General
WARNING
The lift truck must be put on blocks for some
types of maintenance and repair. The removal
of the following assemblies will cause large
changes in the center of gravity: mast, drive
axle, engine and transmission, and counter-
weight. When the lift truck is put on blocks,
put additional blocks in the following posi-

• Before removing the mast and drive axle, put
blocks under the counterweight so the lift
truck cannot fall backward.
• Before removing the counterweight, put
blocks under the mast assembly so the lift
truck cannot fall forward.
The surface must be solid, even, and level when
the lift truck is put on blocks. Make sure that
any blocks used to support the lift truck are
solid, one-piece units. See the Operating Man-

the removal and installation of the counterweight,
hood, overhead guard, and engine (including the
transmission) are found in this section. Checks for
the operator restraint system and procedures for the
repair of tanks and installation of safety labels are
also included.

The hood is connected to the operator module with
hinges. Two gas-controlled springs give assistance
