2.3 REPLACEMENT
Replace O-rings, seals, and gaskets whenever
they are disturbed. Never mix new and old seals
or O-rings regardless of condition. Always lubri-
cate new seals and O-rings with hydraulic oil
before installation.
When replacing parts, use the correct tool.
2.4 HOSES AND TUBES
2.4.1 Inspection
1. If the hose end fittings are damaged, always
replace hoses and tubes . Damaged, dented,
crushed, or leaking hose fittings restrict oil flow
and the operation of the parts being served.
Fittings showing signs of movement from their
original position have failed and must be
replaced.
2. Be sure hoses are in good condition. If in
doubt, replace them.
3. Replace hoses if the following occur:
• chafed outer cover
• concealed corrosion of wire reinforcement.
• ballooning (replace immediately !)
• kinked, crushed, stretched, or deformed.
2.4.2 Installation
1. When installing a new hose, loosely connect
each end and make sure the hose takes up
the designed position before tightening the
connection. Clamps should be tightened
sufficiently to hold the hose without crushing
and to prevent chafing.
2. If a hose is replaced on a moving part, be sure
it does not foul by moving the part through its
complete range of travel.
3. Be sure any hose which has been installed is
not kinked or twisted.
4. Free moving, unsupported hoses must never
touch each other or related work surfaces.
This causes chafing reducing hose life.
2.1 INTRODUCTION
Appropriate service methods and proper repair
procedures are essential for safe, reliable opera-
tion of the forklift and safety of the individual doing
the work. This Maintenance Manual provides
general directions for accomplishing service and
repair work with tested, effective techniques.
Following them will assure reliability.
There are many variations in procedures, tech-
niques, tools, and parts for servicing vehicles, as
well as work skills. This Manual cannot possibly
anticipate all such variations and provide advice or
cautions for each one. Accordingly, anyone who
intends to depart from the instructions in this
Manual must first consider his safety and the
vehicle integrity.
2.2 CLEANING
Clean the exterior of all parts before repairing. Dirt
and abrasive dust reduce the efficient work life of
the part and lead to costly replacement.
Use cleaning fluids and solvents which are suit-
able for cleaning parts and do not risk the safety of
the user. Certain types of fluids damage rubber
parts and/or cause skin irritation.
The following precautions must be observed to
insure hydraulic cleanliness:
1. Flush hose and tube assemblies with a solvent
compatible with hose assemblies. Blow out
excess solvent with shop air.
2. Cap hydraulic fittings and protect threads until
installation.
3. Cap hoses and tube assemblies until installa-
tion
4. Flush hydraulic reservoir, fuel tank, and gear
housing with a suitable solvent to remove
paint, metal chips, welding shot, etc.
5. Protect system components from airborne
contaminants. Plug all cylinder, valve, reser-
voir, tank, and pump openings until in-
stallation.
6. Use clean, filtered oil when filling the system.
7. System cleanliness level must be a minimum
ISO code 18/15 particle ratio count.
