2. General
WARNING
The lift truck must be put on blocks for some
types of maintenance and repairs. The removal of
the following assemblies will cause large changes
in the center of gravity: mast, drive axle, engine
and transmission, and counterweight. When the
lift truck is put on blocks, put additional blocks in
the following positions to maintain stability:
• 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 Manual or the
section Periodic Maintenance 8000YRM1750
NOTE: For lift trucks equipped with a PSI 2.0L LPG
engine, see PSI 2.0L LPG Fuel System
0900YRM1739 for procedures to remove and install
the exhaust system components. If lift truck is
equipped with a Yanmar 2.6L diesel engine, see
Exhaust System Repair in this manual for procedures.
This section contains the description of the frame (see
Figure 1) and connected parts. Procedures for
removing and installing the counterweight, hood,
overhead guard, engine and transmission, cooling
system, exhaust system (see NOTE above), and
other components attached to the frame 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.

3. Description
The frame is one weldment and includes the hydraulic
tank and fuel tank for gasoline or diesel fuel. See Fig-
ure 1.
There is a counterweight for each capacity of lift truck.
The counterweights are similar in appearance, but are
different weights. See Counterweight Replacement
section.
The muffler is fastened to the frame inside the coun-
terweight.
The overhead guard, cowl, and hood are installed on
the frame. The hood is connected to the frame with
hinges. Two gas-controlled springs provide assis-
tance when raising the hood and hold the hood in the
open position. The floor plate and side covers can be
removed for access to the engine, transmission, and
other components.
