Electrocution Hazard Warning
DANGER
THE MHP14AT / MHP13AT AERIAL WORK PLATFORM, IN STANDARD
CONFIGURATION, IS NOT ELECTRICALLY INSULATED
If the platform, scissor arms assembly or any other conductive part of the machine contacts a high voltage electrical conductor the result can be SERIOUS INJURY or DEATH for persons on or near the machine.
GO NO CLOSER THAN THE MINIMUM SAFE APPROACH DISTANCES
(M.S.A.D) - SEE BELOW)
Be sure to allow for sag and sway in the wires and the work platform.
If the machine comes in contact with a live electrical conductor, the entire machine can be charged.
If that happens, you should remain on the machine and not contact any other structure or object within reach. That includes the ground, adjacent buildings, poles, and any other object not part of the machine.
Such contact could make your body a conductor to the other object creating an electrical shock hazard resulting in SERIOUS INJURY or DEATH.
DO NOT attempt to enter or leave the machine until you are sure the electricity has been turned off.
If the machine is in contact with a live conductor, the platform operator MUST warn others on the ground in the vicinity of the machine to STAY AWAY from the machine, since their bodies can also form a path for electricity to ground thus creating an electrical shock hazard with possible ELECTROCUTION and DEATH.
DO NOT attempt to operate the machine ground controls when the platform, scissor arms assembly or any other conducting part of the machine is in contact with electrical wires or if there is an immediate danger of such contact.
Regard all conductors as energised.
Personnel working on or near the machine must be continuously aware of electrical hazards, recognizing that SERIOUS INJURY or DEATH can result if contact with an electrical wire does occur.
IMPORTANT - M.S.A.D.
It is the operators responsibility to ensure M.S.A.D., (Subject to local regulations and laws),
are known and adhered to.

Note
Whilst some of the safety rules and guidelines that follow may not apply specifi cally to this machine (e.g. references to driving) they are included as part of an overall safety strategy relating to the use of elevating work platforms.
Work Place Inspection and Practices
Do not use the MHP as a ground for welding. Ground to the work piece.
Before the MHP is used, and during use, check the area in which the MHP is to be used for possible haz­ards such as, but not limited to:
Drop offs or holes
• Side slopes
• Bumps and fl oor obstructions
• Debris
Overhead obstructions & electrical conductors
• Hazardous locations
Inadequate surface and support to withstand all load forces imposed by the aerial platform in all operating confi gurations
Wind and weather conditions
Presence of unauthorised persons
Other possible unsafe conditions
Before the MHP is used, determine the hazard classifi cation of any particular atmosphere or location according to ANSI/NFPA 505-1987. Any MHP operated in a hazardous location must be approved and of the type required by ANSI/NFPA 505-1987. While operating the MHP a recommended safety practice is to have trained and qualifi ed personnel in the immediate work area of the machine to:
Help in case of an emergency
Operate emergency controls as required
Watch for loss of control by platform operator
Warn the operator of any obstructions or hazards that may not be obvious to them
Watch for soft terrain, sloping surfaces, drop offs, etc, where stability could be jeopardized
Watch for bystanders and never allow anyone to be under, or to reach through the booms while operating the aerial platform.
Safe Operation
Knowledge of the information in this manual, and proper training, provide a basis for safely operating the MHP. Know the location of all the controls and how they operate to act quickly and responsibly in an emergency. Safety devices reduce the likelihood of an accident. Never disable, modify or ignore any safety device. Safety alerts in this manual indicate situations where accidents may occur. If any malfunction, hazard or potentially unsafe condition relating to capacity, intended use or safe operation is suspected, stop the operation of the MHP and seek assistance. The operator bears ultimate responsibility for fol­lowing all manufacturers instructions and warnings, regulations and safety rules of their employer and/or any country or regional law.
Electrocution Hazards
The MHP is an all metal boom aerial work platform and is not electrically insulated. Do not operate it near electrical conductors. Regard all conductors as being energised. Do not operate outside during a thunderstorm.
Pre-start Inspection
At the start of each work shift, the MHP shall be given a visual inspection and function test. See the Daily Inspection and Maintenance chapter 7 in this manual for a list of items to inspect and test.
WARNING
DO NOT operate the MHP unless you are trained and authorised, understand the operation char­acteristics of the machine and have inspected and tested all functions to be sure they are in proper working order.
WARNING
NEVER use an MHP that has a known fault or is malfunctioning in any way until the machine has been repaired by a qualifi ed technician.
Operating a machine in faulty condition could result in death or serious injury.

Use three points of support when getting on or off the platform (two hands and one foot or a similar set of points). Keep the platform clean.
Maintain a fi rm footing on the platform fl oor. Operate the controls slowly and deliberately to avoid jerky and erratic operation. Always stop the controls in neutral before going in the opposite direction.
Do not dismount while the platform is in motion or jump off the machine. Do not start until all personnel are clearly away from the machine.
Do not start until all personnel are clearly away from the machine.
Never cover the fl oor grating or otherwise obstruct your view below. Make sure the area below the plat­form is free of personnel before lowering.
Tipover and Falling Hazards
Operate the machine only on a fi rm, fl at level surface capable of withstanding all load forces imposed by the MHP in all operating conditions.
DANGER
The machine can tip over if it does become unstable. Death or serious injury can result from a tip over accident. Do not drive or position the MHP platform for elevated use near any drop­offs, hole, slope, soft or uneven ground, or other tip-over hazard.
Do not operate the machine from a position on trucks, trailers, railway cars, fl oating vessels, scaffolds or similar equipment unless the application is approved in writing by Snorkel.
Care shall be taken to prevent rope, electrical cords and hoses etc from becoming entangled in the aerial platform. If the platform or elevating assembly becomes caught, snagged or otherwise prevented from normal motion by an adjacent structure or other obstacle such that control reversal does not free the platform, remove all personnel from the platform before attempts are made to free the platform using ground controls.
No person shall access or egress from the platform in the elevated position (except in an emergency) un­less the requirements of AS2550.10 have been met. For full requirements refer directly to AS2550.10.
DANGER
Pinch points may exist between moving compo­nents. Death or Serious injury can result from be­coming trapped between components, buildings, structures or other obstacles. Make sure there is suffi cient clearance around the machine before moving the chassis, booms or platform. Allow suffi cient room and time to stop movement to avoid contact with structures or other hazards.
Keep ground personnel from under the platform when the platform is raised.
Secure all accessories, containers, tools and other materials in the platform to prevent them from accidentally falling or being kicked off the platform.
Always look in the direction of travel. Drive with care and at speeds compatible with the workplace condi­tions. Use caution when driving over rough ground, on slopes, and when turning.
Do not engage in any form of horse play or stunt driving while operating the MHP and do not permit riders on the machine any place other than on the platform.
Remove all loose objects stored in or on the machine, particularly in the platform. Remove all objects which do not belong in or on the machine.
Never steady the platform by positioning it against another platform.
Do not operate an MHP that is damaged or not functioning properly. Do not use the MHP until the machine has been repaired by a qualifi ed mainte- nance person.
Do not operate an MHP that does not have all its de­cals and placards attached and legible.
Watch for bystanders and never allow any one to be under, or to reach through, the machine and its equipment while operating.
Use the recommended transport device when loading the machine.
Operation
If you encounter any suspected malfunction of the aerial platform, or any hazard or potentially unsafe condition relating to capacity, intended use, or safe operation, cease operation immediately and seek assistance from management.

Do not attempt repairs to hydraulic systems unless you are trained. Refer to experienced repair person­nel for help.
Fire Prevention
Never operate your MHP near a fl ame or spark. Hydraulic oil and gasoline are fl ammable and can explode.
Note
This machine is equipped with an internal combus­tion engine (in its standard confi guration) and should not be used on or near any unimproved forest cov­ered, brush covered or grass covered land unless the engines exhaust system is equipped with a spark arrester meeting applicable laws. If a spark arrester is used, it should be maintained in effective working order by the operator.
Engine and Fuel Handling Precautions
WARNING
Engine exhaust contains carbon monoxide, a poisonous gas that is invisible and odourless. Breathing engine exhaust fumes can cause death or serious illness. Do not run the engine in an enclosed area or indoors without adequate ven­tilation.
Only refuel your MHP outdoors in a clear area void of gas fumes or spilled gas.
Never remove the fuel cap or refuel a gasoline engine while the engine is running or hot. ALWAYS allow the engine to cool before refueling. Never allow fuel to spill on hot machine components.
DANGER
DO NOT smoke or permit open fl ames while fueling or near fueling operations.
Maintain control of the fuel fi lter nozzle when fi lling the tank
CAUTION
ENSURE you use an approved fuel container with appropriate fuel fi lter nozzle.
Do not exceed the restricted platform capacity as in­dicated on the capacity placard at the entrance to the platform. Do not carry loads from any point outside of the platform.
Make sure that all protective guards, cowlings and doors are in place and secure. Be sure the guard rail system, including the gate, is in place and secure.
Do not climb on the guardrails or use ladders, planks or other devices to extend or increase your work position from the platform.
Do not use the machine as a crane, hoist or jack, or for any other purpose other than to position person­nel, their tools and materials.
Do not operate the machine in winds, or wind gusts of 28 mph, 45 km/h 12.5 m/s or more.
DANGER
Do not add banners, fl ags, screens or shelters etc to areas of the MHP that are exposed to wind forces as this will increase the wind loading and effect stability.
General Safety Precautions
Do not modify the MHP in any way. When parts or components are replaced, they shall
be identical or equivalent to original Snorkel parts or components.
Do not override any of the safety features of the MHP.
Hydraulic System Precautions
The hydraulic system contains hoses with hydraulic uid under pressure.
DANGER
Hydraulic fl uid escaping under pressure can have enough force to inject fl uid into the fl esh. Serious infection or reaction can result if med­ical treatment is not given immediately. In case of emergency by escaping hydraulic fl uid, seek medical attention at once.
DO NOT place your hand or any part of your body in front of escaping hydraulic fl uid. Use a piece of card- board or wood to search for hydraulic leaks.

This is to allow the unit to be operated by unlicensed operators in accordance with Australian Legislation.
WARNING
An Australian operator MUST hold a WP cer­tifi cate of Competency in order to operate the machine in excess of 11m.
Height Restriction on MHP13AT
The MHP13AT (in standard mode) is fi tted with a re- strictor in the upper hydraulic lift cylinder to keep the platform to a maximum height of 10.9m.
10.9 Meter Restriction Kit
Machines that are built for the Australian market may be fi tted with a 10.9m restriction kit.
This kit which can be fi tted to the MHP14AT is fi tted to restrict the maximum height to the platform fl oor at
10.9m from the ground.
Note
See the Options chapter page 6 for details concerning this kit.
Safety Decals and Placards
There are a number of safety decals and placards on the MHP. Their locations and descriptions are shown in this section on the following pages. Take time to study them.
CAUTION
Be sure that all the safety decals and placards on the MHP are legible. Clean or replace them if you cannot read the words or see the pictures. Clean with soap & water and a soft cloth. Do not use solvents.
Note
From time to time certain Snorkel decals may be deleted, altered or replaced, or new decals may be added in line with new safety regulations or machine specifi cation changes.
If you are unsure or want to check a particular decal or its placement on the machine contact your nearest Snorkel dealer or the Snorkel website.
Do not fi ll the fuel tank to capacity. Allow room for expansion.
If gasoline is spilled, clean up spilled fuel immedi­ately, push/tow the MHP away from the area of the spill and avoid creating any source of ignition until the spilled fuel has evaporated.
Tighten the fuel tank cap securely. if the cap is lost, replace it with an appropriate cap from Snorkel. Use of a non-approved cap without proper venting may result in pressurization of the tank.
Never use fuel for cleaning purposes. For diesel engines, use the correct fuel grade for the
operating season.
Batteries
Charge batteries in a well ventilated area free of ame, sparks or other hazards that might cause fi re or explosion.
WARNING
Batteries give off hydrogen and oxygen that can combine explosively. Death or serious injury can result from a chemical explosion. Do not smoke or permit open fl ames or sparks when checking batteries. Battery acid can damage the skin and eyes. Serious infection or reaction can result if medi­cal treatment is not given immediately. Wear face and eye protection when working near batteries.
CAUTION
If acid contacts your eyes, fl ush immediately with clear water and get medical attention. If acid con­tacts your skin, wash off immediately with clear water.
Height Restriction
IMPORTANT
The height restrictor fi tted to the standard MH- P13AT, is not the same device as the 10.9m restriction kit, although both of these devices achieve the same result of restricting the maxi­mum height of the platform to 10.9m from the ground.

If you have the optional foot switch fi tted the enable switches on the upper control box and ground control box will still function.
Platform Overload Protection
As soon as either boom is raised out of the travel cra­dle (a boom stowed switch changes state) the over­load protection system becomes active.
If 90% of rated capacity is reached in the platform the overload light will illuminate.
This is a warning to the operator that the platform is reaching rated capacity. Normal function will remain and the machine can continue to be used.
• If 100% of rated capacity is reached in the plat­form, the overload light will continue to illuminate and an alarm will sound.
This is a warning to the operator that rated capacity has been reached and the platform load must be re­duced. Normal function will remain to allow the platform to be positioned to remove some load from the platform.
• If 110% of rated capacity is reached in the plat­form the overload light will continue to illuminate and an alarm will continue to sound and all func­tions will be disabled.
The operator must remove load from the platform. Normal function will resume once the platform load has been reduced below 110% for at least two (2) seconds.

The RCD (Residual Current Device) is located at the base and will protect against short circuits to earth. When there is a short circuit the RCD will shut down the 230V AC power to the platform outlet.
To reset the outlet disconnect the power tool lead from the platform control box and reset the RCD at the base. If the problem persists call a trained service technician.
Stabiliser/Boom Interlock Test
All machines in the Snorkel ‘MHP’ Series of Trailer Mounted Elevated Work Platforms are fi tted with a very important safety feature, a ‘Stabiliser/Boom Interlock’ system that prevents the booms being ele­vated to an unsafe position unless all four stabilisers have been correctly set and have made fi rm contact with the ground.
IMPORTANT
The correct operation of the Stabiliser/Boom Interlock is critical to ensure that the MHP is operated safely and without risk.
Detailed instructions on how to carry out a test to ensure that this function is working correctly are provided at the beginning of the Pre-Operational In­spection chapter in this manual.
Flashing light (Option)
The fl ashing light alerts people that the booms / platform of the MHP are moving. The light fl ashes at about one fl ash per second any time the Master Key switch is on. There is no On/Off switch for the ashing light, it cannot be turned off while the MHP is running.

Hydraulic Oil Level
Figure 4.3 - Hydraulic Oil Level
The hydraulic oil level gauge is attached to the side of the hydraulic tank. Read it only when the booms are fully lowered and the stabilisers are raised in the travel position.
The hydraulic oil level should be between the two (2) marks on the decal.
If necessary, add hydraulic oil at the fi ller cap. See the ‘Specifi cations’ chapter 3, for type and grade of hydraulic oil.
Hourmeter
Figure 4.1 - Hourmeter
The hourmeter is basically an electric clock. It accumulates time when the master key switch is turned on. The hour meter cannot be reset. An MHP qualifi ed service technician can use it to tell when it is time for the periodic maintenance listed in the main­tenance manual.
Level Bubble
Figure 4.2 - Level Bubble
A level bubble is mounted on the trailer base. Watch the bubble while you set the stabilisers. Lower the stabilisers, front ones fi rst, one (1) at a time just enough to center the bubble in the middle on top of the gauge. When the bubble is central the platform is level and the platform can be safely raised.

Electrical Circuit Protection
There is only one (1) fuse, on a standard MHP, that is accessable to the operator. Its purpose is to protect the electrical circuits from electrical overloads. When the fuse blows replace it with an identically rated fuse. If the fuse blows a second time, take the MHP out of service and refer to a qualifi ed trained service tech- nician for repair.
RCD/ELCB Outlet (Option)
Figure 5.1 - RCD/ELCB Outlet
The RCD (Residual Current Device) is located at the base and will protect against short circuits to earth. When there is a short circuit the RCD will shut down the 230V AC power to the platform outlet.
To reset the outlet disconnect the power tool lead from the platform box and reset the RCD at the base.
If the problem persists call a trained service techni­cian.
Stabilisers
Figure 5.2 - Stabilisers
The MHP booms cannot be raised unless the sta­bilisers are set and the lift enable light on the lower control box is lit. Once the booms are raised from the stowed position the stabilisers become disabled until the booms are stowed in the travel position.

Page 7-1
Rev C
MHP14AT & MHP13AT
At the start of each work day (or 8 hour shift) an MHP qualifi ed operator must perform the Pre-Operational Inspection as listed in the table below.
The purpose of the Pre-Operational Inspection is to keep the MHP in proper working condition and to de­tect signs of malfunction at the earliest possible time.
This chapter shows how to perform the inspec­tion and maintenance required for each item in the Pre-Operational Inspection table.
Pre-Operational Inspection Table
The MHP should be in the stowed position and the master key switch set to off before you begin this inspection.
Defective parts and/or equipment malfunctions jeop­ardize the safety of the operator and other personnel, and can cause damage to the machines.
WARNING
Do not operate an MHP that is known to be damaged or malfunctioning. Repair all equipment damage or malfunctions, before placing the MHP into service.

Stabiliser / Boom Interlock Test
All machines in the Snorkel MHP Series of Trailer Mounted Elevating Work Platforms are fi tted with a very important safety feature, a ‘Stabiliser / Boom Interlock’ system that prevents the booms being ele­vated to an unsafe position unless all four stabilisers have been correctly set and have made fi rm contact with the ground.
This same safety feature also prevents the Stabilisers being operated while either or both booms are elevated.
The correct operation of the Stabiliser/Boom Interlock is critical to ensure that the MHP is operated safely and without risk.
DANGER
To ensure the interlock system is functioning correctly , before operating the MHP the following test MUST BE CARRIED OUT PRIOR TO OPER­ATION EACH DAY, in conjunction with all other relevant daily Pre-Operational checks.
1. Position the machine on a fi rm level surface. Chock the wheels as required, engage the parking brake, and remove the machine from the towing vehicle.
2. From the base controls, start the engine and allow it to warm up. Remove the travel pins from both the upper and lower booms (as applicable to the model). Move the Stabiliser/Boom selector switch to ‘Boom’.
3. Attempt to raise the Upper Boom; it must not rise out of the boom rest at all. Repeat this step for the Lower Boom. It must not rise at all either. If the booms will rise from the boom rest, proceed to Step 5.
DANGER
4. If either boom rises from the boom rest and con­tinues to rise higher than approximately 400mm,
stop the engine immediately!
Using the Emergency Lowering valve, lower the Boom into the boom rest, remove the machine from service and affi x a Danger Tag warning others that the machine is not to be used.
In the fi rst instance contact the owner of who will then contact the Snorkel branch or authorised agent to in­spect, repair and test the machine before allowing it
to be placed back into service.
5. Follow the correct procedure in the Operators manual for setting up the machine on the Stabi­lisers.
6. When the stabilisers are correctly set, the green Enable Lamp is lit and the machine is level, move the Stabiliser / Boom selector switch to ‘Boom’.
7. From the base controls, raise the Upper Boom (no more than) approximately 400mm from the boom rest.
IMPORTANT
Move the Stabiliser / Boom selector switch to the ‘Stabiliser’ position.
8. Using the stabiliser controls, operate one (1) of the Stabiliser control switches or levers (any one). There must be no corresponding movement of the stabiliser for the switch or lever used. If the stabiliser does not move, lower the Upper Boom back into the boom rest, and repeat steps 7 and 8 for the Lower Boom.
9. If there is no corresponding movement of the Stabilisers when Steps 7 and 8 are followed for both Booms, the Stabiliser / Boom Interlock cir­cuit is functioning correctly and the machine can now be used safely as per the instructions in the Operations Manual
DANGER
10. If there is a corresponding movement of any of the Stabilisers when Steps 7 and 8 are followed,
stop the engine immediately.
Using the Emergency Lowering valve, lower the Boom into the boom rest. Re-start the engine and fully retract all four stabilisers. Remove the machine from service and proceed as in Step 4.

Note
Pay particular attention to the emergency stop switch (7) to see that it turns the MHP engine off when the button is struck.
Emergency Lower
There are two manual bleed down valves to operate from the ground position. One controls the descent of the lower boom and the other controls the descent of the upper boom. The lower boom must be lowered rst.
Ground station
Figure 7.21.1 - Emergency Lower Valve,
Controlling Lower Boom
The valves are opened by pushing in the red knob and turning it anti-clockwise 180 degrees.
With the booms raised, open the valve on the lower boom (see fi gure 7.21.1). The boom should begin to lower.
When the lower boom has fully descended, open the valve for the upper boom (see fi gure 7.21.2). The boom should begin to lower.
Figure 7.21.2 - Emergency Lower Valve,
Controlling Upper Boom
Note
The manual emergency lower valves must be closed after the test to ensure proper boom operation. This is achieved by pushing in the knurled red knob and turning it 180 degrees clockwise.
For full details on emergency lowering operating pro­cedures see ‘Emergency Operation’ chapter 9.
Upper control box
Emergency lowering from the upper control box is achieved by operating the Emergency Lower switch­es together. With the booms raised operate the emergency low­er and enable switches. The booms should begin to lower together.

Platform Control Switches
Figure 7.22 - Platform Control Switches
On the ground control box set the Ground / Platform selector to platform.
Check that each of the platform moving switches ( (1) through to (5) ) cause the platform to move the way it should.
Check both positions of each switch. For correct operating procedures see the ‘Operation’
chapter 8.
Note
Pay particular attention to the Emergency Stop switch (6) to see that it turns the MHP engine off when struck.
Pay particular attention to the platform Enable switch or the platform foot switch (if that option is fi tted) to see that the platform moving switches are deactivat­ed when the enable switch is not operated.
At the completion of the above section the unit can be returned to the stowed position.
AC Outlet RCD / ELCB (Option)
Figure 7.23 - AC Outlet RCD / ELCB
If the MHP has this option fi tted check the RCD works by connecting a power source to the base inlet and an appliance to the platform outlet.
Push the test button on the RCD / ELCB device and the power outlet at the platform should not work.
CAUTION
RCD / ELCB devices should only be replaced by a qualifi ed electrician.
Placards and Decals
Look to see that all placards and decals are in place and legible. Clean dirty or obscured decals with soap and water and a soft lint cloth. Replace any missing or illegible placards or decals before placing the MHP into service for the daily work shift.
Note
Owing to manufacturing variances and customer preferences there may be some small differences in the decal layout on specifi c machines.

Operation Considerations
To use this chapter, fi rst decide whether you will be starting and operating the MHP from the ground control box or the platform control box.
Stabiliser Operation
Note: All Stabiliser Operations
The stabilisers will only function when the platform is fully lowered and the booms are stowed. Once the booms are raised the stabilisers will not operate.
Once the platform is raised the stabilisers cannot be set or adjusted.
Operating Procedures
This chapter explains how to properly start and op­erate an MHP14A T/MHP13AT. Read and understand all the previous chapters in this manual before you begin to operate an MHP.
CAUTION
Do not leave the MHP engine running if you are sandblasting. Sand drawn into the air intake can erode engine parts.
Control Stations
An MHP can be operated from the ground control box or from the platform control box. There are basically two differences between ground control and platform control operations, both are safely related:
1. The ground control station can override the platform control station at any time. If a person operating the machine from a platform becomes incapacitated, a person on the ground can al­ways take over machine control.
2. The stabilisers can only be selected from the ground control station and only when the booms are in the stowed position.
DANGER
The MHP14AT / MHP13AT is not electrically insulated in its standard form. Death or serious injury to operating person­nel, can occur if the machine should come into contact with energised electrical wires during operation. Do not attempt to operate the MHP14A T/MHP13AT ground controls if the platform, booms or any other conducting part of an MHP is in contact with energised electrical wires or if there is an immediate danger of such contact.
Note
See the ‘Electrical Hazard’ section in this manual for complete explanation of the hazards concerning electricity.
Emergency Stopping
To stop an MHP, press the red emergency stop button in, on either the ground control box or the platform control box.
Page 50
Page 8-2
Rev C
MHP14AT & MHP13AT
8. Operation
Before operating the stabilisers check to see that the ground controls conditions under the four stabiliser pads is fi rm, stable and unobstructed.
DANGER
If the platform is up and the ground compress­es unevenly under different stabiliser pads the MHP might fall over causing serious injury or death. Check the level bubble frequently during operation. If any movement of the bubble occurs, immediately lower the platform and readjust the stabilisers to re-center the bubble in the ring.
When using the stabilisers always check that all four are fi rmly on the ground and that they are clear of manhole covers, drains etc, which may collapse. If the ground is at all soft, steel plates at least 300mm x 300mm x 6mm should be placed under the feet to spread the weight.
DANGER
Death or serious injury can result if an MHP tips over. Do not use the stabilisers to gain extra working height, they are not designed for that purpose. At least one of the stabilisers should raise the MHP above the ground - use the other three to level the MHP as necessary.
Note: Operating The Stabilisers
Before you can operate the stabilisers you need to start the engine. See ‘Starting From Ground Control Box’ on page 3.
Using the manual stabiliser valves
Ensure the Boom / Stabiliser switch (item (5) on the ground control box) (see fi gure 8.7) is set to stabiliser.
Activate the stabilisers with the valve levers (down­wards) (See fi gure 8.3).
Note
Ensure that the front stabilisers are lowered fi rst to prevent damage to the jockey wheel.
Figure 8.3
Lower the rear stabilisers and level the machine using the level bubble (see fi gure 8.4) adjacent to the control levers.
Figure 8.4
WARNING
When leveling the machine in either the manual or automatic mode care is required to ensure that all the foot plates are fi rmly on the ground, the machine is level and the lift enable light is on be­fore entering the platform.
Raising the manually operated stabilisers
Raising the stabilisers is the reverse of setting the stabilisers.
Ensure that the Boom / Stabiliser switch is set to stabiliser.
Raise the stabilisers by activating the individual valve levers (upwards).
Note
Ensure that the rear stabilisers are raised fi rst to pre- vent damage to the jockey wheel.

Bi-Energy, Petrol/Diesel / 24V DC
These are various Bi-Energy options available for the MHP14AT / MHP13AT. The following describes the Petrol/ Diesel / 24V option.
This consists of a combination of both a gasoline or diesel engine and a 24V DC motor to give a Bi-Ener­gy option.
Specifi cally a 24V DC motor is mounted on the column under the left hand side cover. This provides an alternative power source to the gasoline or diesel engine.
The DC motor is powered by four “Deep Cycle Trac­tion Batteries” mounted 2 each side of the column and an automatic battery charger that is also mount­ed on the column.
DC motor
The DC motor is mounted under the left had side cover (see fi gure 11.1).
Figure 11.1 - DC Motor
DC motor operation
A Fuel / Electric switch is used to select either the gasoline / diesel engine or the DC motor. This switch is mounted on the front of the lower con­trol box (see fi gure 11.2).
Figure 11.2 - Fuel / Electric Switch
If the gasoline / diesel engine is selected [switch up] the DC motor will not function and if the DC motor is selected [switch down] the gasoline / diesel engine will not run.
DC motor battery switch
In order to operate the DC motor the 24V DC bat­tery isolator switch, mounted at the center rear of the column, will also need to be switched on (see fi gure
11.3).
Figure 11.3 - DC Motor Battery Isolate Switch
Note - 24V DC Battery Switch
When operating the gasoline / diesel engine the 24V DC battery switch should be turned to the off position.
Setting the automatic stabilisers
In order for the stabilisers to function an additional switch (see fi gure 11.4) needs to be operated.
This switch, mounted adjacent to the stabiliser valve levers, must be held on in the stabiliser enabled (1) position while the individual stabiliser valves are operated.
Figure 11.4 - Stabiliser Enable Switch
Note - Stabiliser Enable Switch
This switch is only fi tted to units that have manual stabiliser valve levers.
Setting the automatic stabilisers
When the Automatic Stabiliser Option is fi tted there is no need to use the stabiliser enable switch described above.
For automatic stabiliser operation refer to the Oper­ation Chapter.

Operation
Once the DC mode is selected the motor will then power all the functions in the normal manner, (exclud­ing the manual stabiliser operation described above).
The only difference is that the DC motor will only run when a function is selected e.g. raising a boom.
Batteries
Since the Bi-Energy MHP is powered by “Deep Cycle Traction Batteries” Particular attention should be paid to the batteries on-board charger to ensure proper operation.
The batteries are mounted at each side of the column (see fi gures 11.5 and 11.6).
Figure 11.5 - Two DC Motor Batteries
(Lower Control Box Side)
Figure 11.6 - Two DC Motor Batteries
(Petrol / Diesel Engine Side)
IMPORTANT
The side covers must be removed / raised whilst charging to allow gasses to escape.
DANGER
Lead-acid batteries contain sulphuric acid which will damage eyes or skin on contact.
When working around batteries, always wear a face shield to avoid acid in the eyes.
If acid contacts eyes, fl ush immediately with clear water and get medical attention.
Wear rubber gloves and protective clothing to keep acid off the skin, if acid contacts the skin, wash off immediately with clear water.
Lead-acid batteries produce fl ammable and explosive gasses. Never allow smoking, fl ames or sparks around batteries.
Battery charger
The Bi-Energy MHP is fi tted with an on-board charger (see fi gure 11.7). The charger will completely re- charge the batteries and automatically turn off after the cycle is completed.
Figure 11.7 - On-Board Battery Charger
The battery charger is fi tted with an ‘interlock’. This means that during the charging cycle all functions on the machine are inoperative and will remain so until the charger unit is switched off.
The charging cycle may last from 1 to 12 hours depending on the state of the batteries.
If the charging cycle should exceed 16 hours (indicat­ing a fault) the charger will automatically shut down and the batteries should be checked.
The inlet for connection of mains power to the char­ger is mounted under the left hand side cover and can be accessed with the side cover removed (see gure 11.8).

IMPORTANT
Do not recharge the batteries unless the electro­lyte level has been checked.
DANGER
Do not allow smoking, fl ames or sparks around batteries.
IMPORTANT
Do ensure the side covers are removed / raised during the charging process to allow gasses to escape.
Batteries general maintenance
Always keep the batteries clean, free of dirt and corrosion. A fi lm on top of the battery can accelerate discharge.
Cold reduces battery capacity and retards charging. Heat increases water usage and can (in extreme circumstance) result in over charging. Use distilled water to refi ll the batteries. Avoid water containing metallic solids such as iron.
Batteries - charging
Fully recharge the batteries, immediately after use. One charging cycle per day is preferred. Fully charged batteries perform best. The deeper the discharge, the fewer the number of cycles a battery will deliver. Deep discharges deteriorate the battery quicker then shal­low cycles. An overly discharged battery may need to be cycled a few times before it can fully recover. If a battery begins to heat before becoming fully charged, it may be necessary to recharge and discharge the battery a few times.
The MHp is equipped with an automatic battery char­ger that will completely recharge the batteries and turn off after the charge cycle is complete.
Bi-Energy, Petrol/Diesel / 240V AC
Another Bi-Energy option available for the MHP is the 240V AC / Petrol/Diesel option described below.
This consists of a combination of both a gasoline or diesel engine and a 240V AC motor to give a Bi- Energy option.
Specifi cally a 240V AC motor is mounted on the column under the left hand side cover. This provides an alternative power source to the gasoline or diesel engine.
The AC motor is powered from an external AC power source.
AC motor
The AC motor is mounted under the left hand side cover (see fi gure 11.9).
Figure 11.9 - AC Motor
AC motor operation
A Gas/Electric switch is used to select either the petrol/diesel engine or the AC motor (see fi gure

AC power connection
In order for the AC motor to operate (when the petrol / electric switch is in the electric position) an AC power source must be connected to the MHP (see fi gure
11.11).
Figure 11.11 - AC Power Input Connector
Operation
The same controls are used to stop, start and operate the electric motor as are used for the petrol / diesel motor.
If the petrol / electric switch is in ‘electric mode’ but no AC power source is connected the MHP will default to petrol operation when the ignition switch is activated.
Bi-Energy, hydraulic oil tank.
For both Bi-Energy options described an additional feed line from the hydraulic oil tank is used (see fi g- ure 11.12).
Figure 11.12 - Bi-Energy Hydraulic Tank
Other Options
Air Line To Platform
This consists of pressure fl ex yellow hose rated at 150 psi working pressure, fi tted with quick disconnect couplers at each end.
Work Lights
Rubber encased work lights can be fi tted to the plat- form guardrails. The lights are swivel mounted and each has its own switch.
Flashing Light
Mounted on the lower boom the fl ashing light alerts people that the MHP is moving. The light fl ashes at about one fl ash per second any time the master key switch is on. There is no ON/OFF switch for the ashing light, it cannot be turned off while the MHP is running.
Battery Isolate Switch
Isolates the battery power and can be locked into the off position.
Figure 11.13 - Battery Isolate Switch
Alternative Power Options
There are a variety of alternative power options available for the MHP. These consist of: Diesel engine, 24V power, 240V power and 110V power.
RCD / ELCB AC Outlet
A 3 core wire rated at 600 volts AC 15 amps is run up the booms as standard.
