Section 2 General Instructions

6036/6036T S/N 9B0500 thru 14833

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 personal safety and

then vehicle integrity.

2.2 CLEANING

Clean the exterior of all parts before repairing. Dirt

and abrasive dust reduce the efficient working 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.

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.
