Inspection of Mast, Carriage, Header Hoses,
Lift Chains, and Attachments
WARNING
Lower the lift mechanism completely. Never allow
any person under a raised carriage. DO NOT put
any part of your body in or through the lift mecha-
nism unless all parts of the mast are completely
lowered and the lift truck traction motor is OFF.
1.
Inspect the welds on the mast, cylinders, and
carriage for cracks. Make sure that the cap-
screws and nuts 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 load backrest extension for cracks
and damage.
4.
If the lift truck is equipped with a sideshift car-
riage or attachment, inspect the parts for
cracks and wear. Make sure the parts that fas-
ten the sideshift carriage or attachment to the
carriage are in good condition.
WARNING
Always wear the proper protective equipment in-
cluding eye protection and petroleum-resistant
gloves when handling hydraulic oil. Thoroughly
wash oil from exposed areas of skin as soon as
possible.
WARNING
Never check for leaks by putting hands on hy-
draulic lines or components under pressure. Hy-
draulic oil under pressure can be injected into the
skin.
5.
Visually inspect hoses/fittings for hydraulic
leaks; hose covers for cuts, cracks, or exposed
reinforcement; defective/broken clamping devi-
ces or sheaves; and proper tracking during op-
eration. Adjust/repair/replace hose/components
as necessary.
6.
Check that lift chains are correctly lubricated.
Use SAE 30W engine oil to lubricate lift chains.
7.
Inspect the lift chains for cracks or broken links
and worn or turned pins. Lift chains must be
replaced as a set. See Figure 8.
NOTE: Chain anchor pins MUST be replaced any-
time chains are replaced.

Inspect the chain anchors and pins for cracks

by authorized personnel.
