Operator's manual – Page 7

Preface

The Operator’s Manual contains important information on the operation, servicing, maintenance and
inspection of your

Menzi Muck A111.

A copy of this Operator’s Manual should always be kept in the pocket provided for it in the driver’s cab.

We recommend that you read through the Operator’s Manual carefully and repeatedly and take note of
the information given therein. The Operator’s Manual does not contain instructions for carrying out major
repairs and installations. The performance and availability of your MENZI MUCK walking excavator is not
just dependent on the machine but are largely influenced by the operating personnel. Continuing opera­tional reliability is only guaranteed if the machine is correctly handled and serviced. Operating errors
and inadequate maintenance, on the other hand, lead to breakdowns in use and avoidable repairs. It is
therefore in your interest to work in accordance with the operating instructions. The suitability and ability
of the excavator driver are of great importance. Frequent changing of the excavator driver may impair the
functioning of the machine and should be avoided. Better performance is achieved if the excavator driver
handles the machine sensitively and without using force. MENZI MUCK AG has an extensive customer
service organisation with well-trained specialist personnel, who will check over and repair your Menzi
Muck in case of need. When ordering please observe the ordering instructions in the spare parts book.
When making written or telephone enquiries, state the type designation and the machine number.

Page 8 – Operator's manual

Menzi Muck A111E

Type-plate

On the intermediate wall in the cab underneath the operator's seat you can find the type-plate with fol­lowing contents: producer's address, type of machine, chassis-No. and engine-No., year of construction
and engine rating, total weight (without bucket) and max. permissible weight, axle load front and rear.

Notes for spare part orders

Use only original Menzi Muck spare parts.
For every order, specify the complete part number, name and quantity of the required parts.
For every order, specify the type and production number of the machine (type plate).
The buyer is responsible for any incorrect deliveries as the result of incomplete ordering information.
Prepare telephone orders carefully. In order to avoid inconvenient enquiries and possible incorrect
deliveries, an order must contain precise listings of address, postcode, shipment method, and
destination, and these must be easily legible.

1.2 Warnings and use instructions

Be sure to understand the following warning and use notes:

Warning: Danger or unsafe action, which may result in serious injury or death.

Warning: Danger or unsafe action, which can result in only mild injury, but can cause serious
property damage, financial losses or environmental harm.

Note: Information intended to provide the user with use the product in an efficient and
technically correct manner, or to understand product characteristics.

1.3 Safe handling of fuel

Exercise care in handling fuel: it is highly flammable. Never smoke while fuelling
the machine and make sure that no open flame or sources of sparks are nearby.
Shut down the motor while fuelling the machine. Only fuel outdoors. Prevent fires
by making sure the machine is kept free of dirt and greasy residue. Always clean
up spilled fuel.

1.4 Emergency preparedness

Be prepared for potential fires. Keep a first aid kit and fire extinguisher within
reach at all times. Keep the emergency numbers for doctors, ambulance,
hospital, and fire department available at the telephone at all times.

1.5 Safe handling of starter uids

Starter fluids are highly flammable. When using starter fluid, keep away from sparks
and flames. Keep starter fluid away from batteries and cables. To prevent accidental
discharge during storage of pressurised containers, do not touch the seal cap
and store the container in a cool, safe place. Do not burn or puncture starter fluid
containers.

1.6 Wearing protective clothing

Wear close-fitting clothes and the necessary safety gear for the task at hand.
Safe operation of the equipment requires the complete attention of the operating
personnel. While operating the machine, do not wear headphones for listening
to music or the radio.

1.7 Noise protection

A long-lasting, high noise level can result in hearing damage or deafness. When exposed to
loud noises, wear proper heading protection (for example, earmuffs or earplugs).

Operator's manual – Page 13

1.8 Safety during maintenance tasks

Maintenance tasks require that those performing them are familiar with the procedures
involved. Keep the work area clean and dry. Only perform tasks such as lubrication,
maintenance and adjustments when the machine is at a standstill. ake sure that
hands, feet and clothing do not come within reach of moving parts. Switch off all
drive systems and release pressure using the controls. Lower the equipment to the
ground. Shut off the engine. Remove the key. Allow the machine to cool off. Build
an accident-proof support under machine parts that must be raised for maintenance. Always check all
parts for good condition and proper installation. Fix damage immediately. Replace worn-out or damaged
parts. Remove accumulations of lubricating grease, oil or dirt.

1.9 Safe maintenance of the cooling system

Severe burns can be caused by explosion-like fluid leaks from the pressurised cooling
system. Shut off the engine. Do not remove the radiator cap until it has cooled down
enough to touch it with bare hands. First turn the cap to the first stop to release the
pressure; then, only after the pressure has been released, remove it completely.

1.10 Good workplace ventilation

Exhaust gases can cause severe injury or death. If an engine must be operated in a
closed room, guide the exhaust gases out of the room using an exhaust extension. If no
exhaust extension is available, open the doors to allow outside air to enter.

1.11 Precautions for high-pressure liquids

Escaping high-pressure liquids and cause severe injury. Therefore, de-pressurise the machine before
disconnecting lines. Tighten all line connections before re-pressurising the machine.
To search for leaks, use a piece of cardboard. Protect hands and body from high­pressure liquids. In case of injury, seek a doctor’s assistance immediately. If a liquid
has penetrated the skin, a doctor must be consulted.

1.12 Avoiding heat build-up around pressurised lines

Severe burns can be caused by flammable mist resulting from heat build-up around pressurised lines.
Do not cause any heat build-up around pressurised lines conductors or other flammable materials by
welding, soldering or use of a welding torch. Pressurised lines can be accidentally
separated if heat develops beyond the immediate flame area.

1.13 Removing paint before welding or heating

Avoid the formation of poisonous vapours and dust. Dangerous vapours can form if paint is heated by
welding or soldering, or when it is heated with a welding torch.

Remove paint before heating:

• Remove a minimum of 70mm of paint from the area to be heated

• When removing the paint by sandblasting or sanding, do not inhale the dust this
generates. Wear appropriate breathing protection equipment.

• When using a solvent, the solvent must be removed with soap and water before
welding. Remove containers of paint thinner and other flammable materials from the
work area. Wait at least 15 minutes before welding or heating, so that the vapours can
dissipate.

Do not use any chlorinated solvents in areas where welding is performed.
Perform all work in a well-ventilated area, from which poisonous vapours and dust are ventilated.
Dispose of paint and solvents according to regulations.

1.14 Compliant disposal of waste

If disposal does not take place according to regulations, the environment and ecological
systems can be harmed. Drain fluids into leak-proof and sealed containers. Do not use
food or beverage containers from which someone could mistakenly drink. Never pour
waste on the floor, down the drain or into a body of water. Information about the correct
recycling or disposal method is available from the locally responsible environmental
protection office or from the dealer.

2 Directions of safe operation

2.1 Operators

MENZI MUCK excavators may only be operated or serviced by these people who:
a) are physically and mentally capable
b) have been instructed in the operation and servicing of the machine, and who have proved their

capability and from whom one may expect that they
c) are reliable enough to carry out the responsibilities assigned to them.
d) They should have a permit from the owner to operate or service the machine.

2.2 Operating

The machine should only be operated from the operator’s seat. Ensure that all hand rails and foot steps
(i.e. those parts used for entering the machine) are kept in a perfect condition.

2.3 Operating instructions

For servicing, maintenance, repair and transport work please follow the manufacturer’s instruction
manual. The contractor is responsible for adapting safety instructions to local laws and conditions, where
necessary. Operating instructions and written directions should be displayed visibly in the operator’s cab
or at the site of operation.

2.4 Road driving

Menzi Muck may only be driven on public roads when a permit has been obtained.

2.5 Danger Zone

No one is allowed within the machine’s danger zone. The danger zone is that area around the machine
where people could come to harm through operational movements (of the machine it’s hydraulic arm or
accessories) or through falling debris or collapsing machine parts. The operator may only operate the
machine when no one is within the danger zone. The operator must warn those people of approaching
the danger zone. If they do not leave the danger zone, the operator must stop work. Compliance with
these instructions will ensure that those accidents that are typical for excavator operations, e.g. when
transferring loads or during spotting etc. are avoided.

2.6 Safety distance

To avoid danger of crushing, a safety gap of minimum 0,5 m / 1,5 ft should be left between the machine
and solid constructions such as buildings, working faces, scaffolding and other machines. If for some
reason the safety gap cannot be maintained, then the gap should be barricaded.

2.7 Stability

The machine may only be operated as long as it’s stability is assured. Factors which can impair the
machine’s stability are: overloading, unstable subsoil, sudden acceleration or working on very steep
slopes. Important also is that the operator adapts his style of work to the environmental conditions, and
that loads should be moved as near the ground as possible (to lower the center of gravity).

Operator's manual – Page 17

2.8 Working in the region of underground cables

Before commencing excavation work, the contractor should clarify whether, within the planned working
area, there are any underground cables or pipes which represent a potential danger to persons working
there. If this is the case, then with the cooperation of the cable’s or pipe’s owner or operating body, the
cable’s or pipe’s pathway should be exactly plotted and relevant safety precautions should be taken.

2.9 Working in the region of overhead wires

When working with the MENZI MUCK in the region of overhead wires, it is imperative to maintain a
safety distance between the wires and the MENZI MUCK and it’s accessories, the safety distance to be
directly proprotional to the rated voltage in order to avoid grounding. This safety distance is valid also for
attachments and loads.
The following safety distances are to be observed:

Rated voltage Safety distance

up to 1000 V 1.0 m / 3,28 ft
from 1 kV to 110 kV 3.0 m / 9,84 ft
from 110 kV to 220 kV 4.0 m / 13,12 ft
from 220 kV to 380 kV 5.0 m / 16,4 ft
when unknown 5.0 m / 16,4 ft

In case of sparking, the operator should remove the machine from the danger area, by raising or
lowering the hydraulic boom, or by driving or swivelling the boom away. If none of these are possible,
the operator should:

1. not leave the cab

2. warn those nearby not to approach nor to touch the machine

3. demand that the electricity be turned off.

2.10 Working underground or in enclosed areas

Menzi Muck with diesel engine may only be used in enclosed areas galleries or tunnels when these are
well ventilated.

2.11 Working interruptions

Before breaks and at the end of the day, the operator must ensure that the excavator boom is either
resting on the ground or is secure enough that it cannot move. Under no circumstances is the operator
to leave the machine until the excavator boom has been lowered or secured.

Page 18 – Operator's manual

Menzi Muck A111E

2.12 Lifting operations

Under the term “lifting operations” is understood the lifting, transporting and lowering of secured loads,
whereby assistance is required for fastening and loosening the load. Included is also the extraction
and lowering of pipes, shaft collars etc. It must be ensured that no one stands underneath the load
or operating attachment. The operator is not to swing the load over nearby persons. Loads must be
fastened that they cannot slip or fall off. Assistants must always stay within the operator’s vision. The
operator should move loads as near the ground as possible and avoid swinging the load. When using
the excavator for lifting and pipe-laying operations, the pipe laying operator should approach the boom
only from the side and only with the operator’s permission to be given only when the machine and boom
are no longer in motion.

2.13 Servicing, maintenance

Before all servicing and maintenance operations, and when refuelling, engine is to be switched off.
When working on the electrical system or when conducting welding operations, the battery should be
disconnected in order not to damage the alternator and to avoid accidental start of operation. On MENZI
MUCK with electric motor, all electrical devices and all connections should be switched off and protected
against accidental and non-authorised operation. Exceptions to these rules are those servicing and
maintenance operations which require a running motor.

2.14 Protective guards

Protective guards on moving parts may only be opened or removed when the motor is switched off and
protected against accidental and non-authorised operation. After completing assembly, servicing or
maintenance work, replace all protective guards.

Operator's manual – Page 19

2.15 Articulated steering lock

On machines with articulated steering, the steering
mechanism must be positively locked for repair and

maintenance work with the safety bar (A).
The steering mechanism must also be positively locked with
the safety bar (A) to prevent movement when the machine is
loaded or transported using hoists.

The red safety bar (A) is located at the back of the vehicle,
immediately above the fuel chassis tank.
To mount the safety bar, the MENZI MUCK must be
positioned in line (not bent).
First detach the swing pins and the safety bar, then fasten to
the chassis (B) on the right side of the vehicle.

The safety bar must be secured using the swing pins (C).

Page 20 – Operator's manual

Menzi Muck A111E

2.16 Valves, hydraulic hoses

The rated pressures on the MENZI MUCK safety and control valves may not be adjusted without the
manufacturer’s permission. As soon as damage or leakage of the hydraulic hoses has been diagnosed,
they are to be replaced. Only hydraulic hoses recommended by the manufacturer are to be used.

2.17 Starting operation

Before operating the machine, check the oil levels, diesel engine and cooling water, hydraulic oil, swing
transmission. For the mobile version check wheel hub transmission. Check also cooling water of diesel
engine.

Before starting the Menzi Muck ensure persons are clear.

1. Insert ignition key and turn to Position 1. Now display unit must be initialised.

2. Turn ignition key to Position 3 and start engine. Release ignition key as soon as engine starts up.
Attempt starting continuously for a maximum of 10 seconds. Wait for approximately 1-2 minutes
between each starting attempt to enable the battery to recover.

3. The warning indicators may not appear when the engine is running. Refer to the operating manual
of the engine manufacturer in case of faults and when starting in winter.
The engine is equipped with a flame glow plug. During cold starting, preheat with the ignition key
in Position 2 for approx. 15 seconds. Operation can be monitored with the indicator on the display.
Then start as described in point 2.

4 The engine is equipped with a flame glow plug. At low temperatures, this is activated automatically

by the engine’s ECU. Its function can be checked on the indicator on the display.

2.18 Shut-off operation

When not in use operator must lower boom and chassis. Furthermore, in winter, the hydraulic hoses on
the chassis and the piston rods must be cleaned so that dirt does not freeze on to them.
– Set back speed adjusting lever so that the engine is made to idle. Do not switch off engine from full

load but let it idle for three minutes to equalize the temperature. Shutting down from full load can
lead to turbo damage.

– Turn ignition key to position 0, engine shuts off. The engine can also be shut off with the Emergency

switch but must be unlocked before starting by turning, otherwise the engine can not be started.

Caution: During work breaks or when work ends, remove ignition key and make it inaccessible
to unauthorized persons.

Operator's manual – Page 21

2.19 Excavator operation

– As soon as the diesel engine has reached its operating temperature and is running at a speed

between 50 and 75% of the max. speed, start the operating or driving movements so that not only
the hydraulic tank but the whole hydraulic system is uniformly heated. In this way the machine will
quickly reach its full working performance. For excavating operation the diesel engine should run at
least 65% of the max. speed. According to the operating activity, the speed must be changed via the
speed adjusting lever.

– Slowing down the upper structure by reversing, i.e. switching on the opposite direction of rotation, is

not permissible.
– Never knock off slopes with the boom or dipper or fill in ditches from the side.
– Grade in boom direction only.
– In winter, the machine must be shut down on dry subsoil to prevent it freezing up.
– The excavator is designed for operating in terrain up to 100% in the line of dip and 70% diagonally to

the line of dip without terrain preparation.
– Only persons which are trained adequately and are authorized may operate the machine.
– The contractor is responsible for adapting safety instructions to local laws and condiditions, where

necessary.
– Before starting excavator operation the operator checks effectiveness of operating and safety

elements. During operation he monitors the correct function of the machine.
– Observed defects must be reported to the foreman or to the succeeding operator.
– In the event of trouble which endanger safety of machine operation must be stopped immediately.

2.20 Tips for the operator

Do not cover the sides of the machine or leave it on an
incline.

Do not use the shovel to perform a hammer function.

Do not dig under the excavator on a slope. Place the
shovel in front of the excavator when advancing.

Advancing the shovel: do not raise the brackets too
high from the ground. The boom must remain between
the brackets when performing steering functions with
the chassis.
Caution: Reverse slowly and carefully and do not make
any abrupt movements.

The shovel must be used as a support on the drop side
when advancing across a slope.

6 Controls

6.1 Main switch

The main switch (A) is located at the rear to the right of
the engine support. If the machine is not to be used for
a prolonged period, switch it off so that the batteries are
disconnected from all consumersThe diagram shows the
main switch in the OFF position. To switch it on, it has to
be turned 90° clockwise.If the machine is not to be used
for a prolonged period, switch it off so that the batteries are
disconnected from all consumers.

6.2 Emergency shut down switch

The Emergency shut down switch (4) shuts the machine down immediately
in an emergency situation. The Emergency shut down switch must be reset
before the machine can be restarted. Do this by turning it clockwise.

Before resetting the Emergency shut down switch, ensure that
restarting the machine will not pose any risk.

6.3 Ignition lock

The diagram shows the ignition lock (1) in the idle marked position.
Turning the ignition key clockwise to the first setting switches on the
ignition. The next setting is the glow plug preheat position, which
is not required on this machine since preheating is automatic on
demand. To start the machine, the ignition key must be turned again
until it stops. Keep the ignition key turned until the diesel engine starts.
Release the key immediately and leave in this position. When you want
to switch the engine off, return the ignition key to its original position.

The engine cannot be started if the ignition key was originally turned to

the glow plug preheat position and then allowed to return to the
ignition position. Switch off the ignition and turn the key again to the engine start position.

Page 46 – Operator's manual

Menzi Muck A111E

6.4 Speed adjustment

The DYGSY, together with the engine’s ECU, is responsible for adjusting the engine speed, and thus the
control of the injection device, ensuring economical and efficient operation. For heavy loads, the ECU
equalises the pressure of the diesel engine, making possible a higher capacity.

While the engine is running, the engine speed can be set variably
between upper and lower idle speeds by turning the potentiometer
(2) on the instrument panel clockwise or counter-clockwise. The
speed can be read on the display. The maximum permissible
speeds are limited electronically.

6.4.1 Speed reset

If you press the button (6) on the right joystick, the diesel engine slows down to the lower idle speed.
Press the button repeatedly to raise the engine speed to the setting on the potentiometer.

If the diesel engine is shut off when the reset is
activated, and the potentiometer is not returned to
its default setting, when restarting the engine,the
potentiometer must be returned to its default
setting (turn counter-clockwise as far as possible)
before the speed can be increased. This prevents
running up at the highest speed. The reset button is
automatically restored to its original position.

6.4.2 Engine speed governor at low temperatures

To prevent damage to the engine or the hydraulics, the GLR limits the engine speed to 1450 rpm when
the cooling water temperature is under 40° or the hydraulic oil temperature is under 10°C.
If both values exceed these limits, the GLR increases the engine speed to the speed set on the
potentiometer. If during operation, the water temperature or the hydraulic temperature falls 5° below the
respective threshold value, the governor switches on again.

Operator's manual – Page 47

6.4.3 Emergency speed

Failure of the CANBUS between the GLR and ECU means
the injection pump has no mechanical devices that can
enable an emergency gas function. If a malfunction occurs
and the speed set on the potentiometer is no longer
transferred electronically, the engine will automatically run
on in „Emergency gas“ mode. If the malfunction cannot be
remedied by restarting the control (wait approx. 15 s after
turning back the ignition key) and the machine has to be
moved despite the malfunction, avoid starting and stopping
the engine repeatedly! The emergency gas plug (A) is
located below the rear cover near the right engine support.

The emergency gas plug must remain in place. Do not remove.

6.5 Heating/Air conditioning

The Menzi Muck mobile allterrain excavator is fitted with a manual heater and can be supplied with an
air conditioning system as an option. The system is controlled via the switches and pushbuttons on the
instrument panel. The built-in system is a combined heating and air conditioning system. In order to
optimise climate conditions inside the driver’s cab, heating or cooling can be selected on the basis of
the ambient temperature. In order that the system is always able to reach the required temperature, the
following maintenance operations must be carried out. The suggested maintenance intervals are heavily
dependent on the working environment. We can therefore only provide suggestions for a machine
working under average load conditions and the system components to be maintained.

6.5.1 Air vents

The air circulating in the driver’s cab can be controlled using
the built-in air vents. The air flowing out of the heating/air
conditioning system can be directed as required by turning or
opening/closing the individual vents.

1 Front air vent for demisting/defrosting the windscreen
2 Footwell air vent
3 Right-hand air vent
4 Rear air vent

Page 48 – Operator's manual

Menzi Muck A111E

6.5.2 Control

The controls for the heating and air conditioning system are installed on the instrument panel. Press the
controls numbered in the diagram to adapt the settings of the heating and air conditioning system to
meet your requirements.

18 Air conditioning on/off switch
19 Ventilation on/off switch
20 Step switch for ventilation

6.5.3 Heating

In heating mode, the knob (21) must be turned to the right to set the required temperature. Turning the
knob clockwise increases the heating output. Turn the rotary switch (20) to change the blower speed.
Turning the switch clockwise increases the speed. This increases the air renewal rate inside the driver’s
cab. Changing over the switch (19) in addition closes the recirculated air flap. When the system is in
recirculating air mode, the LED on the switch lights up. As a consequence, the system ceases to draw in
fresh air from outside and simply recirculates the air inside the driver’s cab. This function helps to heat
up the cab when the vehicle is first started up in order to achieve a comfortable ambient temperature
more quickly.

6.5.4 Cooling

To activate the cooling function, the switch (18) must be set to the ice crystal symbol. When the system is
in cooling mode, the LED on the switch lights up. When the cooling function is first activated, the rotary
switch (21) must be turned fully to the left (as far as the stop) in order to maximise the cooling power
of the system. The knob (21) can be used to fine-tune the settings for the air blown out. Turning the
knob (21) to the right increases the temperature. Changing over the switch (19) in addition closes the
recirculated air flap. When the system is in recirculating air mode, the LED on the switch lights up. As a
consequence, the system ceases to draw in fresh air from outside and simply recirculates the air inside
the driver’s cab. This function helps to heat up the cab when the vehicle is first started up in order to
achieve a comfortable ambient temperature more quickly.

7 Operating the upper structure in working mode

7.1 General

7.1.1 Working regulations for hoisting operation in the EC.

Lifting and moving loads with a hook up device, eg rope or chain is called hoisting operation. Dislocation
of pieces, pipes or machines can be such a hoisting operation.

7.1.2 Safety conditions

– Loads may only be moved with activated overload warning device
– Adjustment of overload warning device corresponds to the highest possible stability of the machine,
ie telescoping jacks and wheels must be brought to their widest position and the jacks must be half
extended
– The chassis should be placed as low as possible
– The excavator must be placed on an even and paved ground
– Otherwise, the operator must taken adequate precautions

7.1.3 Working steps

If a load should be moved within the adjusted sector range the overload warning device is switched ON.
If an accoustic or visual signal is triggered when lifting a load or when extending the boom then the load
must be lowered to the bottom immediately (danger of tilting).

Attention: The manufacturer refuses to accept any liability for damage resulting form non-observance of
operating instructions or if the customer carries out changes to the overload warning device.

10 Operation traction drive

10.1 General

10.1.1 Traction drive

The machine is driven via all wheels (4x4) using four hydrostatic wheel hub drives
with hydraulic differential locks.. The transverse differential lock can be enabled at
the switch (25).

Disable the lock when driving on roads or if the chassis is set wide.

The wheel hub drives are equipped with an automatic parking brake. The spring pressure disk brake is a
safety brake that is always closed by compression springs. It is opened by the supply of pressurised oil.
The brake does not need to be adjusted, and thus is also maintenance-free.

10.1.2 Driving

Please read following rules, if the machine isn't in drive position.

Directions

Should the upperstructure be positionend in excess of 900 from the driving position, driving controls
will be in reverse order. To check the function of driving controls operate foot pedal with caution. If the
operator isn't sure in which direction the machine's moving, he has to tip softly on the foot pedal before
start driving.

Driving preparation

Prior to driving warm engine 2 - 3 minutes. Raise chassis and stabilizers off the ground. Parallel steering
stabilizers. Engage steering switch 19 to lock in steering. Place boom assembly between driving wheels.
Steering by the Joy Stick (change into steering mode)

10.1.3 Driving up steep roads

Steep roads must be navigated with the following engine setting:

1. With one speed: Maximum revolutions (2000 rpm), control the speed using the foot pedal.

2. With 2 speeds: Maximum revolutions (2000 rpm.), drive in first gear and control the speed using the

foot pedal.

In this setting, the diesel engine has adequate braking force and cannot therefore be over-revved.

Page 66 – Operator's manual

Menzi Muck A111E

10.2 Driving mode / steering mode

The switch (9) can be used to select normal or automatic driving mode.When the switch is deactivated,
steering is not permitted. Moving the switch to the first or second setting or pressing the button (1) on
the right joystick activates the steering.The machine is steered by moving the joystick to the
left and to the right.

Steering movements that are initiated when the upper structure is not facing
the direction of travel are counteracted.

10.2.1 Conventional driving mode

Moving the switch (9) to the first setting interrupts the bucket function and
activates the steering.Pressing button (1) on the right joystick achieves the
same result. The speed can be controlled using the accelerator pedal and
the engine revs.

10.2.2 Automatic driving operation

Moving the switch (9) to the second setting switches off all boom
functions apart from the steering function. Engine revs and drive
pump are synchronised via the accelerator pedal. This achieves an
automatic-like characteristic; the revs increase on acceleration and
decrease on deceleration. The potentiometer limits the top speed
and releases the accelerator more sensitively.

Use only automatic mode when driving on public roads.

10.2.3 Controlling the traction drive speed

The switch (13) can be used to toggle between first and
second gear. The potentiometer (8) on the instrument panel
enables continuous limiting of the top speed.

10.2.4 Braking

If the MENZI MUCK is to be brought to a standstill, allow
the accelerator pedal to return to its centre position. If this
deceleration is inadequate, locknuts can be used to shorten the brake
path (by controlling the pedal in the opposite direction).

11 Transport

11.1 Transport instructions

Use transport vehicles only if they are in proper functioning condition and are licensed for road travel.

If loading the vehicle using loading ramps:

• Never exceed a drive pitch of 15°.

• The width of the ramps must be no less than 1 to 2-times the width of the wheels.

• Clean the ramps and vehicle wheels of dirt, mud, ice and snow.

• Always take into account the variance in wheel track width between the front and rear wheels.

• Anchor the drive-up ramps on the transport vehicle to prevent them from slipping.

• To ensure safety, provide additional support in the middle of the ramps.

• When loading, engage the parking break on the transport vehicle and put blocks under the wheels.

After loading

• Lower the machine and the excavator arm onto the bed of the transport vehicle. Shut off the engine.
Locking the hydraulics.

• The hydraulic brake valves on the drive are activated when the drive and control lever are activated.
Lock the cab and remove the ignition key.

• After loading the excavator, place blocks under its wheels and secure (lash) the blocks onto the bed
of the transport vehicle so that they cannot slip, tip or otherwise move from their positions.

• The machine can be lashed down only at suitable points. Watch for hydraulic lines and moveable
protective panelling.

• Check the total height and make any necessary adjustments.

Operator's manual – Page 69

11.2 Loading example

This example illustrates how a standard-model MENZI MUCK walking excavator is loaded without the
use of ramps. This loading method may only be carried out by trained drivers and then, only at the
driver’s own liability.

Lower bucket to loading area of truck. Raise wheels up to the height of loading area

and move back truck (bucket slides over the
loading area)

Lower wheels. Swing upperstructure.
(Pull boom and dipper when swinging)

Lift stabilizers and push excavator onto truck.

Lower chassis to loading area. Observe loading height (4 metres) and secure

excavator.

11.3 Transport by helicopter, crane or skyline crane

If it is to be transported by helicopter, crane or skyline crane, secure the machine as shown in Figure (1).
Do not attach the lifting tackle to the cab. The company that undertakes transportation of the machine is
responsible for ensuring that the requisite lifting gear and lifting tackle is of suitable design and adequate
load-bearing strength for safe transportation. See page 9 of this instruction manual for details of the
weights.
The machine can be disassembled if the available lifting gear and lifting tackle is not of sufficient load­bearing strength to lift the machine as a complete unit. In this case it is essential to take all necessary
precautions to ensure safe disassembly and reassembly. It is particularly important to ensure strict
compliance with all applicable water-quality management regulations and stipulations. Fluids and
lubricants must be collected in suitable containers and correctly disposed of if necessary. The weights of
the individual components are listed below.

MENZI MUCK AG expressly refuses to accept liability for damage caused by incorrect
disassembly and assembly of components and the use of contaminated fluids and lubricants.

Maintenance and repairs

12 Tips and hints

Regular and proper servicing and inspection are essential for the faultless operation and long service life
of your excavator. Preventative Maintenance is the simplest and cheapest method of servicing.

12.1 Maintenance

– The engine must be stopped before all service and repair work. Protective devices for moving

machine parts must only be opened or removed when the machine is shut down. At the same time
it must be ensured that the engine cannot be put into operation by unauthorized persons. Only tilt
cab with the cabin door closed. The cabin must be mechanically secured in the tilted state (danger
of accident).

– Defective parts must be promptly replaced to avoid greater damage.
– After using the excavator on an extensive scale, it must be thoroughly cleaned.
– To pevent corrosion damage, regularly grease all exposed parts.
– After completion of maintenance and repair work, put all protective devices properly back again.
– See to the tightness of all bolt connection as well as to leaks in the hydraulic system.
– Pay special attention to correctly tighten nut and bolts. Check and retighten wheel-nuts regularly.
– If there is any visible loss of oil, determine the cause and remedy the fault.
– Retighten hydraulic connections in the event of leaks.
– Replace damaged pipes and hoses immediately with new ones.
– Check machine for cracks and reweld, if necessary.
– Pay attention to the lubrication schedule and to the maintenance work of the Perkins engine.
– Thoroughly clean grease fittings before greasing.
– Change oil only when machine is operationally warm, as warm oil runs off better.
– All filters are carefully adapted to the machine. Trouble-free operation and long service life of the en-

gine and the hydraulic parts can only be achieved if original parts are used.

– Use only original parts. This ensures a trouble-free operation and a long lifetime. Menzi Muck AG on-

ly gives warranty for original parts.

– Do not mix different brands of lubricants with one another, as the quality is possibly influenced by

this. Lubricate according to the maintenance schedule indicated in the lubricating instructions.
Environmental protection provisions must be observed when removing operation materials (i.e., oil,
grease, fuel) etc. from oily components, such as filters.

– 500 hour service only by authorized workshops.

Operator's manual – Page 75

– Shut down engine and activate ignition. The hydraulic system has to be at zero-pressure

by activating the control lever and opening the hydraulic tank screw-cap (hydraulic tank is
pretensioned).

– Shut down engine. Exceptions are only allowed for maintenance and repair works which cannot be

carried out without running engine.

– If in the absence of an assembly pit, the excavator has to be hoisted by the boom, legs or wheels,

work should begin on the chassis only when the raised side of the excavator has been stabilised.

(e.g. timber underlay)
– Disconnect battery when carry out welding jobs.
– After completing servicing, assembly maintenance operations, replace all safety devices.
– Use only original spare parts to ensure correct function and warranty conditions.
– Carry out adjustments on engine or hyraulic system according to manufacturer’s specifications. In

no case, change original adjustments without consulting with the manufacturer.
– Ensure that all important parts of the excavator, such as hand rails and foot steps (i.e. those parts

used for entering the vehicle) are kept in perfect condition.
– All observed defects should be reported to the responsible foreman or to the succeeding operator.
– If you know there is a malfunction, a part that needs adjustment, stop the machine immediately.
– After conclusion of repair works check effectiveness of operating elements and safety devices.
– The pump housing must be filled before the pump is started following any work on the hydraulic

pump.

It is worth reading this lubricating schedule attentively and carefully observing the individual points. In
this way you will help to avoid failure and to give it a longer service life. You will save time, money and
annoyance.

13 Engine and air-conditioning unit

13.1 General

This Operating Manual contains no detailed information on servicing, starting or maintaining the
diesel motor. It provides only auxiliary, important and machine-related data. Please refer to the engine
manufacturer’s Operating Manual for detailed information.

13.1.1 Welding work

If welding work is carried out on the machine, the following precautions must be taken to protect
the electronic components.

1 Disconnect the earth cable from battery to machine.
2 Remove all connectors to ECU and injection pump.
3 Clamp earth gripper of welding unit to the part to be welded. Not over a long distance, since earth

can be restored by cable or similar. This could result in damage.

13.2 Inspection cooling water

The coolant level must be checked every day prior to beginning work. This is easily done by opening
the right casing (see chapter opening side casing). The
level in the cooling unit must completely fill the gauge (A).
Additionally, the level in the expansion cylinder is continually
monitored and displayed on the display (see „Status
displays“). If the display lights up during operation, the
coolant is low and must be replenished immediately. This
is achieved by tipping the cab (see chapter tilting cab). The
coolant cover (B) is located toward the rear under the cover.

When the engine is warm, the coolant circuit is under
pressure. Be carefully when opening the radiator cap
not to be burned by spraying steam.

The cab cannot be tilted completely, as otherwise
the heater would be above the level of the radiator,
resulting in the potential formation of air bubbles in

the system.

Page 86 – Operator's manual

Menzi Muck A111E

13.3 Cooling water quality

The cooling water quality you used has a significant influence on the efficiency and life span of the
cooling system. Basically, a mix of maximum 40- 60% anti-freeze should be used. Use clean and soft
water for the cooling system (see the operating manual provided by the engine manufacturer).

13.4 Cleaning radiator

The engine, hydraulic, charge and air conditioning coolers must be cleaned periodically and any dirt
removed. Regular maintenance is especially essential when working in extremely dusty environments
and damp weather. The radiators are mounted in a maintenance-friendly location on the right-hand side
and can be easily accessed by opening the engine cover.

The air-conditioner radiator can be pushed forward by
loosening the screw (A) and can then be folded downward,
providing easy access to the radiators located behind it.

The radiators must not be damaged by excessive
water pressure.

Operator's manual – Page 87

13.5 Servicing the air lter

The interval for servicing the air filter unit depends on the
dust concentration in the air and on the speed of the engine.
Ideally the filter cartridges are only cleaned or replaced when
the service switch is activated (no later than the ordered
hours). However, every time on starting up the engine it
should be briefly brought up to its maximum speed, and then
it should be observed whether the lamp lights up, and thus
the functioning of the monitoring system is checked. If the
monitoring system does not respond it has to be assumed
that the engine can be put into operation for the whole day
without any faults within the filter system occurring.

1 Remove the fixing screw (A).
2 Swivel the air filter forwards.
3 Unlock the dust collector / dust cap (B) of the air filter, rotate to

the left and remove.
4 Carefully move the filter end (C) back and fro to break the seal.
5 Pull the filter (C) from the outlet pipe and out of the housing.
6 Thoroughly clean inside the filter housing and the outlet bore.
7 To replace the main filter insert (A), carefully pull out the filter

insert. Replace the main filter insert immediately with a new insert

to prevent dust penetrating the air intake system.
8 Fit the new or the cleaned preliminary filter insert. Place the hand

at the outer filter edge and apply pressure.
9 Refit the dust collector / dust cap of the air filter, turn to the right

and lock.

Remove the main filter insert (safety insert) (A) ONLY if you
want to replace it. Do NOT attempt to clean, wash or reuse

the main filter insert. Under normal circumstances, the
main filter insert ONLY needs to be replaced if there is a hole in the
preliminary filter insert.

Please refer to the engine manufacturer’s Operating Manual for
detailed information on replacing the air filter cartridge.

Page 88 – Operator's manual

Menzi Muck A111E

13.6 Engine oil and lter change

Dismantle the engine plate (A) before changing the engine
oil and filter. Undo the screws at the back of the engine
plate and remove it. The Menzi Muck must be in a horizontal
position to enable the engine oil to flow away cleanly. Before
starting, place a suitable vessel below the drain.

1 Run the engine for 5 minutes to warm up the engine oil.

Switch off the engine.
2 Remove the oil sump drain plugs (B).
3 Drain the engine oil only when warm.

4 Rotate the filter insert (C) using a suitable filter button

and remove. Dispose of the oil filter insert.

The oil must be correctly filtered to ensure efficient
lubrication. Replace the filter at regular intervals.
The used filter must conform to the John Deere

specifications.

Operator's manual – Page 89

5 Apply clean engine oil to the new filter at the internal (A) and

external (B) seals and apply to the filter thread.

6 Wipe both sealing surfaces of the filter head (C, D) using a clean

cloth. Make sure that the grooves in the dust seal (E) are correctly
located in the slots in the housing. Replace the dust seal if
damaged.

Once the filter insert has been fitted, TIGHTEN only BY HAND.
A filter key may be used ONLY for REMOVAL. Make sure that
the grooves in the dust seal (F) are correctly located in the

slots in the housing.

7 Screw the oil filter on by hand until it is flush with the dust

seal (F). Do not, as is normal practice with standard
filters, tighten the filter by an additional 3/4 to 1 1/4
rotation once the filter is in contact with the seal.

8 Tighten the drain seal to the specified torque. (Drain

seal with copper washer 70 Nm, drain seal with O-ring
50 Nm)

9 Fill the engine crankshaft housing with the specified

motor oil through the oil fill seal (F) on the engine side.
The correct quantity is stated in the Specifications
Section.

Immediately after an oil change, rotate the engine for
30 seconds without allowing it to start. This ensures
the engine components are adequately lubricated

before the engine starts.

The fill quantity can vary slightly. Always top up the
crankcase until the oil level is within the hatched
area. Do not overfill.

10 Switch on the engine and allow to run so that it can be

checked for leaks.

11 Switch off the engine, wait for 10 minutes and then

check the oil level (G). The oil level should be within
the hatched area (G) on the dipstick.

13.7 Fuel lter replacement

1 Clean around the fuel filter thoroughly.
2 Remove the wire from the water sensor (A).
3 Loosen the drain seals (B) and drain the fuel into a

suitable container.

Raising the securing ring as it is being turned makes
it easier to rotate over the catch.

4 Hold the securing ring firmly and turn 1/4 rotation

clockwise (as viewed from the top). Remove the ring

and the filter insert (D).
5 Check whether the filter base is clean. Clean as

required.

To ensure correct installation, the guide pin on the
fuel filter housing must line up with the slots in the
mounting base.

6 Attach the new filter inserts (D) to the mounting bases.

Make sure that the inserts line up and are firmly seated

on the bases. The filter may have to be rotated so that it

lines up correctly. Remove the filter insert from the water

collector (E). Empty and clean the collector. Dry with compressed air. Attach the pot to the new

insert. Tighten.
7 Line up the shim on the filter insert with the slots in the filter base.
8 Attach the securing ring to the mounting base, ensuring that the filter base is fitted with the dust

seal. Tighten the securing ring anticlockwise by hand (approx. 1/3 of a rotation) until a clicking noise

is heard indicating that is has engaged. Do NOT over-tighten the securing ring.

Correct installation is signalled by a clicking noise and when the securing ring is felt to be loose.
The new insert is supplied with a stopper for plugging the used insert.

9 Reconnect the water sensor wiring.
10 Bleed the fuel system. (See Bleeding the fuel system Section). Tighten the bleed screw (F).

Operator's manual – Page 91

13.7.1 Bleeding the fuel system

Prevent fuel contamination. Do not open fuel lines to
bleed the fuel system.

1 Manually undo the bleed screw (A) at the fuel filter base

by two full rotations.

2 Actuate the fuel pump preliminary lever (B) on the fuel

filter base until fuel escapes from the bleed screw.

3 Tighten the bleed screw. Continue to actuate the

preliminary pump until there is no noticeable pump
effect.

4 Switch on engine and check for leaks. If the engine will

not start, repeat steps 1-4.

13.7.2 Drain off condensation at the fuel filter

Condensate water can be drained from both the preliminary fuel filter
and the fuel filter. This is normally done during a service and filter
change.If engine performance starts to drop, check to make sure there
is no water in the filters. Provide a suitable vessel. The bleed valve (C)

13.8 Cleaning the crankcase bleed pipe

1 Remove the crankcase bleed pipe (A) and clean.
2 Fit the bleed pipe. Make sure that the O-ring is correctly

seated in the rocker cover of the elbow adapter.Tighten

the hose clamp.

13.9 Checking and adjusting valve play

The valve play must be adjusted and re-adjusted after 2000 operating hours. Lower machine in a
horizontal position onto the chassis. The rear, side and engine covers must be removed to enable work
to be carried out unhindered.Please refer to the John Deere Operating Manual for further details.

Operator's manual – Page 93

13.10 Heating/Air conditioning system maintenance

With few exceptions, the heating and air conditioning
system does not require any maintenance. To ensure the
fault-free operation and maximum performance of the
system, depending on dust concentration levels, the intake
air must be flushed out of the air channel in the intake
port at least every 150 operating hours. The intake air
flow will be reduced dramatically if the filter elements are
excessively dirty, considerably affecting heating and cooling
performance. The filter element is easy to maintain and
can be accessed from the left-hand side of the machine by
removing the intake port.

13.10.1 Coolant

The air conditioning system coolant circuit contains approx. 750 g of coolant. The manufacturer
designation of the coolant used, which is a tetra-fluoro-ethane compound, is R134a. Unlike the
compounds used in the past, like R12, which were composed of fluorine, chlorine, carbon and
hydrogen, this coolant meets the conditions and requirements of a modern environmentally-friendly
coolant. However, guidelines governing the use of such coolants, which are designed to protect health
and the environment, must be observed.

13.10.2 Filling

The system is filled before leaving the factory. Special equipment and expert knowledge are required
to fill the system correctly. We recommend that the fill level is checked every 2 years by a specialist
operator or a Menzi Muck Service Centre or service engineer.

13.10.3 Cooling oil

In this case too, the system is filled to the correct level before leaving the factory. Do not open any
couplings on the compressor to avoid the risk of coolant leaking. The correct fill level or residual amount
of compressor oil is checked by Menzi Muck engineers during servicing. However, should you need to
top up the compressor oil, you should only use PAG diester oils. The oil used must be able to combine
with the coolant in order that even system components which are separate from the compressor, in
particular the expansion valve and binary pressure switch, can be lubricated.

13.10.4 Repairs to the coolant circuit

Should repairs need to be made to the coolant circuit, please contact one of our Service Centres or
a specialist operator in your area. You should never make modifications to or carry out repairs on the
coolant circuit. If the coolant heats up, as is the case during soldering and welding, it decomposes and
produces extremely poisonous gases and vapours. Decomposition products are also very aggressive.

14 Electrical equipment

14.1 General

The electrical equipment operates at an operating voltage of 24 Volts. The batteries aredry batteries with
815 A current start. The diesel engine is equipped with a 7.2 kW kw starter motor.
A windscreeen wiper, horn, hour meter, fuel level indicator and two working headlights in front and on the
back are also part of the equipment.
Before commencing work on the electrical system or welding work on the machine, the battery should
be disconnected (first the negative, then the positive terminal) to prevent short circuits. To reconnect­attach first the positive then the negative terminal.

Terminals should be firmly connected and not just lightly laid in. Terminals which are not secure
can cause damage to the electronics and the alternator control unit. Never disconnect terminals
while the engine is running.

Difficult starting of the engine can frequently be attributed to loose or corroded battery terminals.
These overload the life of these components.

Battery power is reduced at lower temperature.

Pause for approximately two minutes each starting procedure so that the battery is able to
recover.

Proceed as follows to protect electronic devices during welding work:

1. Ignition switch to „OFF“

2. Disconnect starter battery. Battery main switch must be off.

3. Connecting the earth terminal to electronic welding devices: The earth terminal must
be connected to the part to be welded. The earth terminal must never be connected via
revolving connections. Undefined welding currents must be avoided.

4. Welding cables must not be laid parallel to electrical lines.

5. Electronic component housings and electrical lines must not come into contact with the
welding electrode.

If one of the stated actions cannot be carried out, the connector must be detached from the
electronic devices prior to welding.

In the case of plasma welding, the connectors must be detached from the CGM, the DIGSY
Compact and other electronic devices prior to welding.

Procedure for fast battery charging
Fast battery charging for powering the control and control components requires the battery to be
disconnected.

Procedure for jump starting combustion engines
Combustion engines may only be jump started with the starter battery disconnected.
