Inspection Of Forks, Mast And Lift Chains
(See FIGURE 17. and FIGURE 18.)
WARNING
Never work under a raised carriage, forks or mast
channel. Lower the carriage or use blocks and chains
on the mast weldments and carriage so that they can
not move. Make sure the moving parts are attached
to a part that does not move.
Do not try to correct fork tip alignment by bending
the forks or adding shims. Replace damaged forks.
Never repair damaged forks by heating or welding.
Forks are made of special steel using special proce-
dures. Replace damaged forks.
1. Inspect the welds on the mast and carriage for cracks.
Make sure that the nuts and bolts are tight.
2. Inspect the channels for wear in the areas where the
rollers travel. Inspect the rollers for wear or damage.
3. Inspect the forks for cracks and wear. Check that the
fork tips are aligned within 13 mm (0.5 in) of each other
(item 1, FIGURE 17.). Check that the bottom of the fork is
not worn (item 4, FIGURE 17.).
4. Replace any damaged or broken parts that are used to
keep the forks locked in position.
5. Check that the lift chains are correctly lubricated. Use
engine oil to lubricate the lift chains.
6. If the lift truck is equipped with a side--shift carriage or
attachment, inspect the parts for cracks and wear. Make
sure the parts that fasten the side--shift carriage or attach-
ment to the carriage are in good condition.
