Safety Procedures When Working Near Mast 4000 SRM 660
2. If parts of the mast must be in raised position,
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:
a. Put the mast in a vertical position.
b. Raise the mast to align the bottom of the in-
ner weldment to below the anchor for the tilt
cylinders. See Figure 3.
c. Use a 1/2 inch minimum safety chain with
a hook to fasten the weldments together so
that the inner weldment cannot lower. In-
stallthechainonbothsidesofthemast.
Make sure the hooks are completely engaged
with a link in the chain.
d. Lower the mast until there is tension in the
safety chain. If the engine is running, stop
the engine. Apply the parking brake. In-
stall a DO NOT REMOVE tag on the safety
chain. Put a DO NOT OPERATE tag in the
operator’s compartment.
