Checking:
1. Start the Diesel engine for instance from the platform.
2. Set a lever, for instance a wood stick as illustrated between the guide cam B and
the cover.
3.
Press lever A to direction B. The guide B rises deactivating the backup limit switch.
The Diesel engine should now stop running.
4.
If the Diesel engine keeps on operating when the lever is taken away, the Access
Platform must not be used before the fault has been corrected.
Checking of the load lowering valves and the boom sections
1.
Support the Access Platform on the outriggers. Controlling from below, lift the boom
off from the transport support. Turn the boom aside about 10º. Lower the boom to
horizontal position. Extend the telescope boom continuously as long as it goes (the load
control stops it). Leave the engine running.
2.
Operate each outrigger lever back and forth. If the boom is not in the transport
position, the outriggers must not work. If they do, the Access Platform must not be used
before defect has been corrected.
3.
Turn the boom and let it stay about 2 minutes on each outrigger. Watch the
outrigger cylinder. The cylinder must not slide in. Repeat the same with all outriggers.
4.
If the outrigger cylinders or the lifting cylinder slide in, the Access Platform must not
be used before defect has been corrected. See illustrations on page 26.
5.
Switch the engine off. Operate all hydraulic valves, also in the platform. The
lowering movements of the boom and the outriggers must not work, not even slowly. If
they do, the Access Platform must not be used before the hydraulic system has been
checked and repaired.
