Each carrier vehicle driver must perform a visual inspection before starting
work. If the test has negative results, immediately prevent any further use of the
folding fork arms. Commissioning must only be carried out after a successful
repair.
Danger to life due to unsecured vehicle or moving parts!
– Secure the carrier vehicle against inadvertently rolling off (e.g., with a parking
brake or by removing the key).
– Always use a suitable lifting device for heavy parts.
– During the disassembly of folding fork arms, ensure that loosened parts do
not fall down or tip over.
– Immediately place disassembled components to one side to prevent them
falling.
Observe the above points before any maintenance task. Uncontrolled move-
ments of the vehicle or parts can result in serious injuries or even death due to
the high dead weight.
