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.

21. Counterweight Replacement
REMOVE
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 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 procedure How to Put Lift
Truck on Blocks in the Operating Manual or the
Periodic Maintenance section for your lift truck.
WARNING
DO NOT operate the lift truck if the capscrew for
the counterweight is not installed. When the cap-
screw is removed, the counterweight can fall from
the lift truck.
WARNING
LPG can cause an explosion. DO NOT cause
sparks or permit flammable material near the LPG
system. LPG fuel systems can be disconnected
indoors only if the lift truck is at least 8 m (26 ft)
from any open flame, motor vehicles, electrical
equipment, or ignition source.
Close the shutoff valve on the LPG tank before
any part of the engine fuel system is disconnec-
ted. Run the engine until the fuel in the system is
used and the engine stops.
If the engine will not run, close the shutoff valve
on the LPG tank. Loosen the fitting on the supply
hose from the LPG tank where it enters the filter
unit. Permit the pressure in the fuel system to de-
crease slowly. Fuel leaving the fitting removes
heat. Use a cloth to protect your hands from the
cold fitting.
NOTE: The counterweight is held in position on the
frame by two hooks that are part of the frame. See
Figure 17.
One M24 × 3 x 90 capscrew holds the counterweight
to the lower part of the frame. See Figure 17.

REMOVE AND INSTALL
WARNING
DO NOT operate the lift truck without the over-
head guard correctly fastened to the lift truck.
WARNING
DO NOT weld mounts for lights or accessories to
legs of the overhead guard. Changes that are
made by welding, or by drilling holes that are too
big or in the wrong location, can reduce the
strength of the overhead guard.
See your dealer for Yale lift trucks BEFORE per-
forming any changes to the overhead guard.
NOTE: The lift trucks covered in this manual are
equipped with either a high or low overhead guard.
The removal and installation procedures for both
types of overhead guards are the same.
No welding or drilling on legs of overhead guard is
permitted as per previous WARNING.
NOTE: The lifting device can be connected to any
number of positions on the overhead guard depend-
ing upon the lifting device available. The ideal choices
are a four point sling connected to all four corners on
the top of the overhead guard, or a two point sling
connected to two opposite corners of the overhead
guard. If a single point hoist is used, make sure that
the lift point is as close to the center of the overhead
guard. If during the initial start of the lift the overhead
guard is off balance lower immediately and move the
hoist to a more centered point.
1. Connect a lifting device to remove or install the
overhead guard. Loosen clamp and disconnect
the air intake hose from the elbow. Remove bolts,
elbow, retainer, and grommet from the overhead
guard rear leg. See Figure 20.
2. Disconnect any wires between the frame and the
overhead guard. When the overhead guard is lif-
ted from the frame, make sure that any electrical
wires are moved through the holes in the frame
so that they are not damaged.
3. The rear legs of the overhead guard have two
capscrews that are located under the hood inside
the engine compartment, next to the radiator.
Remove and install the capscrews. See Fig-
ure 21.
4. Remove fender cover, dash, and kick panel to re-
move and install the three capscrews on front
legs of overhead guard. See Hood, Seat, and

EMERGENCY LOCKING RETRACTOR
(ELR)
NOTE: The lift truck models covered in this manual
are equipped with the ELR type seat belts. See Fig-
ure 22 and Figure 23.
When the ELR style seat belt is properly buckled
across the operator, the belt will permit slight operator
repositioning without activating the locking mecha-
nism. If the truck tips, travels off a dock, or comes to a
sudden stop, the locking mechanism will be activated
and hold the operator’s lower torso in the seat.
A seat belt that is damaged worn or does not operate
properly will not provide protection when it is needed.
The end of the belt must fasten correctly in the latch.
The seat belt must be in good condition. Replace the
seat belt if damage or wear is seen. See Figure 22
and Figure 23.
NOTE: The following seat belt operation checks must
be performed three times before replacing the seat
belt assembly:
• With the hood closed and in the locked posi-
tion, pull the seat belt slowly from the retractor
assembly. Make sure the seat belt pulls out
and retracts smoothly. If the seat belt cannot
be pulled from the retractor assembly or the
belt will not retract, replace the seat belt as-
sembly.
• With the hood closed and in the locked posi-
tion, pull the seat belt with a sudden jerk. Make
sure the seat belt will not pull from the retractor
assembly. If the seat belt can be pulled from
the retractor, when it is pulled with a sudden
jerk, replace the seat belt assembly.
• With the hood in the open position, make sure
the seat belt will not pull from the retractor as-
sembly. If the seat belt can be pulled from the
retractor, with the hood in the open position, re-
place the seat belt assembly.
Make sure the seat rails and latch striker are not
loose. The seat rails must lock securely in position but
move freely when unlocked. The seat rails must be
securely attached to the mounting surface. The hood
must be fully closed. Lift the hood to make sure it is
closed and will not move. See Figure 22.
Adjust hood, hood latch, and hood latch striker bolt
when any of the parts of the operator restraint system
are installed or replaced. See the section Hood, Seat,
and Side Covers Replacement in this manual for ad-
justment procedures for the hood.
