Make sure the steering system operates smoothly and

EVERY 150 HOURS OR MONTHLY
NOTE: Do these procedures in addition to the 8 hour checks.
LIFT CHAINS, LUBRICATION
Lubricate the lift chains with SAE 30 engine oil. The
best procedure is to remove the chains from the lift truck
and soak them in oil.
WARNING
Do not repair a worn or damaged lift chain. Replace
a worn or damaged lift chain with a new chain. If a
pair of lift chains is used in the mast, both lift chains
must be replaced.
LIFT CHAIN ADJUSTMENTS
(See FIGURE 14.)
When the lift chains are correctly adjusted:
•
The tension will be the same on each chain of
the chain set. Check tension by pushing on both
chains at the same time.
•
The chain length will be correct.
•
The chains must travel freely through the com-
plete cycle.
1. Put a load equal to 80 to 90% of the capacity load on
the forks. Lower the forks as much as possible. Tilt the
mast fully backward.
2. Check the amount that the bottom carriage roller ex-
tends below the inner channel of the mast. The carriage
roller must not extend more than 1.3 in (34 mm) below
the inner channel. If the adjustment is not correct, adjust
the chain anchors. Make sure each anchor is adjusted the
same amount.
3. Remove the load from the forks. Check the clearance
of the carriage when the mast is fully extended. The car-
riage must not touch the top crossmember of the inner
weldment. The chains are too tight if the carriage
touches the crossmember. Put the mast in a vertical posi-
tion and lower the carriage completely. If the forks do
not just touch the surface the chains are too tight. If the
chains are too tight adjust the chain anchors. Make sure
each anchor is adjusted the same amount.

WARNING
Do not repair a worn lift chain. Replace a worn chain
with a new chain. If a pair of chains is used in the
mast, both chains must be replaced.
NOTE: When the chain adjustments are complete,
make sure that the threads on the nuts of the chain an-
chors are completely engaged. Make sure that all of the
adjustment is not removed from the chain anchors. The
chain anchors must be able to move in their sockets.
AIR TANKS
Operate the drain valve to check its operation and to
drain moisture from the air tank. The drain valves are in-
stalled at the bottom of the air tanks.
DRIVE SHAFT
Lubricate the three fittings on the transmission drive
shaft with multi–purpose grease.
