AFETY INSPECTION

This Safety Inspection shall be carried out by the owner immediately prior to
transporting this machine.

This Safety Inspection shall also be carried out by the user prior to use each day.

The procedure is to carry out the following 14 checks in order as follows.

1.Remove the rear chassis covers by means of the two top twist-locks and the two lift­and-turn catches at the sides. The cover is removed by sliding it backwards and
upwards. Use the central handle provided.

2.Ensure that the mast and jib are fully lowered. Remove the hydraulic oil filler cap and
check that the hydraulic oil level is correct. Oil should be visible on the dip stick. Top
up as necessary using hydraulic oil Viscosity Grade ISO 46.

3.Inspect the chassis area for oil leaks, loose parts, frayed cables and hoses and
structural damage etc. Check that all cable connections to the solenoid valves are
intact.

4.Open the Inspection hatches on both sides of the upper mast cover. Check that the AC
mains cable is disconnected from the battery charger. Check the electrolyte level in
each battery cell. Top up as necessary with distilled water only.

5.Use the automated battery top-up system fill the batteries to the correct electrolyte
level. This is done by opening the shut off valve and pressing the green fill button for
approximately 10 seconds, then re-closing the shut-off valve.

Batteries should be examined for cracks, acid leakage and terminal corrosion. Take
corrective action immediately if either check fails.

routing of the hoses and cables. Check the Emergency Lowering feature of the jib.
Ensure that when the Emergency Lowering lever/button is disengaged, the jib no
longer descends. Return the jib to its rest position using the normal Lower Control
Station.

8.Check mast chains by elevating the masts approximately 30cm above the rest
position. Check for correct routing of the energy chain. Raise the masts to full height

chain. Record the approximate deflection i.e. the offset distance from the mast.
Repeat the measurement on the adjacent chain at the same location. Chains bearing
equal load will deflect equal amounts. Carefully adjust the slack chain until the
deflections are approximately equal. Torque up the locknuts to 70 Nm.

NOTE: Apply a thin layer of grease to the lifting chains with a small paintbrush.

Over-tensioning of either lifting chain will result in unnecessary
lifting of the mast and a subsequent increase in machine stowed
height.

The function of the mast straps is to ensure that masts descend in the correct order
and more importantly, that masts cannot continue to descend if the jib or platform
meets an external obstacle. Raise the masts about 30cm. Check the external mast
clamp screws for tightness. Pull on the short length of each strap and check that they
are secure. Refer to the maintenance manual for instructions on more stringent
periodic checks on these straps.

Check the Emergency Lowering feature of the mast. The lever is located in the upper
mast over. Open the left hand battery inspection hatch and locate the ‘Emergency

necessary.

9.Elevate the jib fully. Using the Lower Control Station, turn the mast assembly through
about 90 degrees. Check the correct routing of the hoses and cables and the correct
smooth operation of the energy chain in its chassis base slide. Continue rotating
through 180 degrees in both directions. Confirm that the rotation stops are intact.

10.STANDARD PLATFORM CONTROLS Repeat the mast, jib and rotate functions from
the Upper Control Station in the platform. Check that pressing the emergency stop
button prevents subsequent operation of the joystick.

12.MACHINE TRAVEL - UNELEVATED Travel functions are possible only from the
platform Upper Control Station. As with all such controls, the deadman handgrip switch
must be depressed before any function can operate.

Select Drive on the upper control panel. Pushing back and forward on the joystick
moves the machine backwards and forwards respectively.

The pothole protection will begin to retract immediately. However, full demand speed
will not be realised until the bars are fully raised. This takes about 3 seconds. Check
that the motion alarm DOES sound during travel. Check that the thumb operated
switches on the top of the joystick operates the front wheel steering.

13.MACHINE TRAVEL-ELEVATED While the masts are raised, it is possible to drive and
steer the machine at a much reduced speed. Also note that while the masts are raised,
the pothole protection bars should be fully extended and should remain extended
during slow speed motion of the machine.

The issue of reduced speed while elevated and deployment of the
pothole protection bars is crucial to the safe operation of this
machine.

The machine may not be released or operated unless these
functions operate properly.

14.FINAL PREPARATION Configure the masts and jib to the stowed position. Replace all
machine covers and secure.

4.The MB20/26 may be lifted by forklift subject to the following strict procedure.

5.Ensure that the mast and jib are fully stowed and that the pothole bars are fully
retracted (raised).

L

IFTING

The MB20/26 may be lifted by an overhead hoist/crane subject to the following strict
procedure.
Raise the jib to clear the lifting straps as shown.

Use 4 separate lifting straps connected to a spreader beam. DO NOT use a lesser
number of threaded straps as these could slip and lead to instability. The
recommended minimum capacity of EACH of the 4 straps is 2 tonne and the minimum
length of each strap is 2 metres. Damage to the covers and/or cage rails can occur if a
spreader beam is not deployed during a crane lift.

BY C

RANE

Apply the straps via 1 tonne shackles to each of the 4 lifting lugs on the chassis. See
Figure 9: below.

Figure 11: Lifting by Crane

DO NOT apply lifting straps to any other part of the machine.

a standard loading ramp (Up to 14 degrees).
It is recommended to reverse the machine up on to the truck thus forward travelling

down the ramp at the delivery point. Winch-assisted loading is allowable for larger
slopes, however, operate the trucks assist winch at minimum speed to avoid over­pressurising the hydraulic system in the machine.

When the MB20/26 is on the truck or trailer it should then be made secure by:-

1.Chocking the wheels.

2.Securing with adequate chains or straps to the lifting lugs on the chassis.

DO NOT loop straps through the cage, ladder or jib as this could
cause permanent structural damage during transportation.

RANSPORTATION

Proceed as follows:­Refer to the valve block drawing Figure 13.

1.Fully lower the jib boom and the mast sections. Rotate the mast into the stowed
position.

2.Turn the Upper Control Box to the OFF position and remove the key.

3.Remove the rear GRP cover from the chassis and locate the hydraulic control valve
block.

4.The hand valve marked ‘A’ should be turned fully clockwise to close. The hand valve
marked ‘B’ should be turned fully anti-clockwise to open.

5.Operate the red handpump a number of times to develop sufficient pressure to
‘separate’ the internal brake disks. These brakes are integral with the hydraulic drive
motors.

NOTE: The machine can now be safely towed or winched.

6.On completion of towing/winching, reverse the position of the rotary hand valves ‘A’
and ‘B’. The handpump becomes inoperative when the valves are returned to their
normal position.

RISK OF SERIOUS INJURY. Releasing the brakes will cause the
machine to move uncontrollably on a slope. Damaging momentum
can be developed due to the large mass of a slow moving machine

1.Disconnect the batteries at the quick connect plug and socket. This is located in the
chassis between the controller and the hydraulic tank.

2.Disconnect the battery leads and tape up the lead terminals to ensure insulation.
Better battery life and efficiency is achieved if the batteries are used consistently. It is

therefore recommended that the batteries are used elsewhere if the machine is to be
unused for an extended period (2 weeks or more).
