9. Test the override systems of this unit. The lower controls must override the upper
controls. If the overrides (station selector) are not operating correctly, the machine
should not be used until the problem is corrected.
10. With no one in the platform
, cycle the aerial device functions through the
complete range of motion from the lower control station
. If all functions operate
properly from the lower control station, then test the operation of each function from
the upper controls. While the unit is operating, look for oil leakage from the hydraulic
lines and components. If any function does not operate properly, or an oil leak is
found, the problem must be corrected before further operation of the aerial device.
11. There is an electrical interlock system on the upper controls. When the trigger on the
single handle upper controller is activated, the boom can be moved. When this trigger
is released, it should not be possible to move the boom and it should not be possible
to rotate the unit. The machine must not be operated unless the trigger is working
correctly.
Warning
Platform occupant(s) must always wear a certified CSA or OSHA approved personal
fall protection system attached and secured to the anchor provided.
12. This unit is equipped with an emergency lowering DC pump, start the DC pump from
the portable control to check the pump for proper operation. Then start the DC pump
at the upper control station and check the pump for proper operation (if applicable).
Caution
The DC pump is intended for emergency lowering use only. Do not run for over three
(3) minutes continuously. Damage to the pump or motor can result.
13. The upper controls’ enclosure is a very important part of this unit. It must be kept dry
at all times. If for any reason, a component has to be changed in and/or on the upper
controls’ enclosure, then the seals or gaskets have to be replaced, if they are
damaged. If you suspect that a water seal is damaged, then it must be replaced
immediately.
Warning
Erratic movements of the aerial device can happen if upper controls enclosure is not
kept watertight check all seal and rubbers before to operate.
