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 shift. 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.
• 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.
WHEN WORKING NEAR THE MAST ALWAYS:
• Lower the mast and carriage completely:
Turn the key switch to the ON position and
push the lift/lower control lever forward un-
til 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
mast upright that moves in outer mast with
crossmember on outer mast. On the two-stage
mast, the moving part is the inner mast. On the
three-stage mast, it is the intermediate mast.
On the four-stage mast, it is the first intermedi-
ate mast. See Figure 2 or Figure 3.
3.
Use a 3/8-inch minimum safety chain with a
hook to fasten the crossmembers together so
the movable member cannot lower. 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, fittings, or other parts on
the mast.
4.
Lower mast until there is tension in safety
chain and free-lift cylinder (full free-lift models)
is completely retracted.
NOTE:
Apply the parking brake. After lowering or
restraining the mast, shut off the power, and re-
move key. Put a DO NOT OPERATE tag in the
operator's compartment. Disconnect battery and
put a tag or lock on battery connector.
5.
Install another safety chain (9.5 mm (3/8 in.)
minimum) between the top or bottom bar of the
carriage (item 6, Figure 2) and a crossmember
on the outer mast as a secondary safety device.
Install a DO NOT REMOVE tag on the safety
chain(s).
