WARNING
The following procedures MUST be used when in-
specting or working near the mast. Additional pre-
cautions and procedures can be required when
repairing or removing the mast. See the correct
Service Manual section for the specific mast be-
ing repaired.
• 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 OP-
ERATE tag in the operator's compartment.
Disconnect the battery on electric lift trucks
and put a tag or lock on the battery connec-
tor.
• 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 or 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 proce-
dures in the correct Service Manual for the
mast.
WHEN WORKING NEAR THE MAST ALWAYS:
• Lower the mast and carriage completely.
Push the lift/lower control lever forward and
make sure there is no movement in the mast.
Make sure that all parts of the mast that
move are fully lowered.
OR
• If parts of the mast must be in a raised posi-
tion, install a safety chain to restrain the
moving parts of the mast. Connect moving
parts to a part that does not move. Follow
these procedures:
1.
Put mast in vertical position.
2.
Raise mast to align bottom crossmember of
weldment that moves in the outer weldment
with a crossmember on the outer weldment. On
the two-stage and free-lift mast, the moving
part is the inner weldment. On the three-stage
mast, it is the intermediate weldment. See Fig-
ure 2.
3.
Use a 3/8 inch minimum safety chain with a
hook to fasten the crossmembers together so
the movable member cannot lower. Put the
hook on the back side of the mast. Make sure
the hook is completely engaged with a link in
the chain. Make sure the safety chain does not
touch lift chains or chain sheaves, tubes, hoses,
fittings, or other parts on the mast.
4.
Lower mast until there is tension in the safety
chain and the free-lift cylinder (three-stage) is
completely retracted. If running, stop the en-
gine. Apply parking brake. Install a DO NOT
REMOVE tag on the safety chain(s).
5.
Install another safety chain (3/8 inch mini-
mum) between the top or bottom crossmember
of the carriage and a crossmember on the outer
weldment. See Figure 2.
NOTE: Apply parking brake. After lowering or re-
straining the mast, shut off power and remove key.
Put a DO NOT OPERATE tag in the operator's
compartment. Disconnect battery on electric lift
trucks and put a tag or lock on battery connector.
