TRUCK LUBRICATION AND CHAIN MAINTENANCE

Chain Lubrication

CAUTION
• Lubricate the chains as required by the Operator’s
Daily Checklist beginning on page 1-7.
• Use lubricant listed on the Lubrication Chart located
on page 1-12. Brush lube along all chain surfaces.
• Each pair of chains has been factory-lubricated using
heat and pressure to force the lubricant thoroughly
into the chain links. Avoid removal or contamination
of this factory applied lubricant. Do not wash, sand
blast, etch, steam clean, or paint the chains.
Chain Adjustment
The chain must be adjusted so each strand is under
equal tension for proper load distribution and mast
operation.
To determine whether the chains are properly
adjusted:
1. Remove load from forks.
2. Extend the mast to put the chains under tension.
3. Press the center of a strand of chain with your thumb,
then press at the same place on the other chain of
the pair.
4. Each chain in a pair should have equal “give”. If
tension is not equal, adjust them as described in the
manufacturer’s mast service manual.
Measuring Chain Stretch
If the chains stretch beyond the recommended amount,
they should be replaced in pairs. Chain stretch can be
measured with a chain wear scale. See Figure 6-10. The
scale indicates whether the distance between two chain
links is within tolerance. The shaded area in the
illustration, compares a stretched chain, to a new chain.
Measure the chains according to the instructions printed
on the chain wear scale, without load on the carriage.
• To check the free lift chains, raise the carriage 1 ft.
(30 cm) off the ground to put tension on the chains.
• To check the main lift chains, raise the mast until the
inner upright starts to extend putting tension on the
chains.

Figure 6-10: Measuring Chain Stretch
Check Primary Lift Chain
1. Park the truck on a flat, level surface.
2. Set the mast in the center of the truck, facing straight
ahead, level to the floor and empty (unloaded).
3. Set the key switch to OFF, remove the key and place
the key in a secure area.
4. Measure the distance from the floor to the bottom
heel of each fork tine. Measurement must be 1/8”
(3.175 mm) minimum to 1/4” (6.35 mm) maximum.
If it is not within 1/8” to 1/4” (3.175 mm to 6.35 mm),
adjust the primary lift chain accordingly.
Check Lift Operation
1. Check the lift cylinders to ensure proper sequencing.
If adjustment is needed, see supplier information in
Chapter 7.
The chains must be coated with a film of lubricant
at all times.
