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 outer weldment with
crossmember on 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. On the four-stage
mast, it is the first intermediate weldment. See
Figure 1.
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 (two-stage full free-
lift, three-stage, and four-stage) is completely
retracted. If running, turn the power OFF. Ap-
ply the parking brake. Install a DO NOT RE-
MOVE tag on the safety chain(s).
5.
Install another safety chain (3/8-in. minimum)
between the top or bottom crossmember of the
carriage bar and a crossmember on the outer
weldment.
6.
After lowering or restraining the mast, shut off
the power, and remove key.
NOTE:
Place a DO NOT OPERATE tag in the op-
erator's compartment.
7.
Disconnect battery and put a tag or lock on bat-
tery connector.
