On lift truck models listed below, equipped with a
three-stage full free-lift mast, there are two free lift
chains and chain sheaves. On lift truck models lis-
ted below, equipped with a two-stage limited free-
lift mast, there are no free lift chains or sheaves.
• H2.0-2.5CT (H50CT) (A274)
On all lift trucks, the free-lift chains connect at one
end of the mid-crossmember of the inner mast. Two
chain sheaves are installed on a crosshead on the
rod of the free-lift cylinder. The chains then go over
sheaves on the crosshead and connect to the car-
riage.
Safety Procedures When Working Near Mast
The following procedures MUST be used when in-
specting or working near the mast. Additional pre-
cautions and procedures can be required when re-
pairing or removing the mast.
WARNING
Mast parts are heavy and can move. Distances be-
tween parts are small. Serious injury or death can
result if part of the body is hit by parts of the mast
or the carriage.
•
Never put any part of the body into or under
the mast or carriage unless all parts are
completely lowered or a safety chain is in-
stalled. Also make sure that the power is
OFF and the key is removed. Put a DO NOT
OPERATE tag in the operator's compart-
ment. Disconnect the battery and put a tag
or lock on the battery connector.
•
Be careful of the forks. When the mast is
raised, the forks can be at a height to cause
an injury.
•
DO NOT climb on the mast or lift truck at
any time. Use a ladder or personnel lift to
work on the mast.
•
DO NOT use blocks to support the mast
weldments nor to restrain their movement.
•
Mast repairs require disassembly and re-
moval of parts and can require removal of
the mast or carriage. Follow the repair pro-
cedures in this section.
