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 the power is off
and the key is removed. Put a DO NOT OP-
ERATE tag in the operator's compartment.
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 the correct Service Manual sec-
tion.
WHEN WORKING NEAR THE MAST ALWAYS:
1.
Lower mast and carriage completely. Make
sure all parts of mast that move are fully low-
ered. Push lift/lower control button and make
sure there is no movement in mast.
OR
2.
If parts of the mast must be in raised position,
install a safety chain to restrain moving parts
of mast. Connect moving parts to a part that
does not move. Follow these procedures:
a.
Raise mast to align bottom or middle cross-
member of inner weldment with top of outer
weldment. On the two-stage mast, the mov-
ing part is the inner weldment. On the three-
stage mast, it is both the inner and inter-
mediate weldments. See Figure 5.
b.
Install a safety chain (3/8-in. minimum) with
a hook around lower crossmember of inner
weldment and top of outer weldment. Put
hook on back side of mast. Make sure hook is
completely engaged with a link in the chain.
Make sure safety chain does not touch lift
chains or chain sheaves, tubes, hoses, fit-
tings, or other parts on mast.
c.
Lower mast until there is tension in safety
chain and free-lift cylinder (full free-lift
masts only) is completely retracted. Move the
key to the OFF position and remove the key
from the key switch. Put a DO NOT OPER-
ATE tag in the operator's compartment. Dis-
connect the battery and put a tag or lock on
the battery connector. Install a DO NOT
REMOVE tag on safety chain(s).
NOTE: MAST OPERATOR GUARD MUST BE RE-
MOVED TO INSTALL SAFETY CHAIN. REMOVE
SAFETY CHAIN AND INSTALL THE GUARD
AF-
TER REPAIRS ARE COMPLETE.
