6. Emergency Lower/Slew.
With the top and bottom booms raised approximately 500mm each and the unit switched
off, check:
The emergency slew can be operated with the slew handle provided.
The emergency lower valves located on the lift cylinders lower the boom when pushed in
a slow and controlled manner and that the boom movement is stopped on releasing the
valve
To Reset the hydraulic system after checks;
□ Fully slew the Basket to the right, so that he ram is fully extended.
Fully extend the Outriggers while still maintaining Level. (check the bubble) □
Using the ground controls, fully extend both Top and Bottom Booms. □
Fully extend the Flick Out Boom □ .
All rams must be fully extended at the same time before returning them to their transit
position.

With the unit set up for working (i.e. outriggers down, under load and the machine level
with wheels clear of ground) it is possible to lower the cage using the emergency hand
pump.
8. Battery Power (Where applicable)
Check batteries are fully charged and topped up with distilled water (these.are fitted
under the slew cover on both sides of the platform) and that the Battery Isolating Plug is
securely connected.
Hydrometer reading should be 1280-1320sg.
With machine level, the distilled water should cover the plates by approximately 6mm.
9. Mains Power (Where applicable)
Connect the mains supply, either 110V or 220/240V A.C., depending upon the motor
specification. Check the motor is running when the key is turned to the ON position.
Check that the voltage and frequency of the power input matches that of the motor. All
extensions must be a minimum of 2.5mm², and no longer than 10m due to possible
voltage drop.
10. Petrol Power (Where applicable)
Check the fuel and oil levels of the engine. Switch on the ignition using the key switch on
the slew mounted legend panel. Check the engine runs using the start and stop buttons
in the basket. Check that there is sufficient oil and fuel to complete a full working shift.
