7) 7) AIR CLEANING AIR CLEANING
Always maintain a lift truck in a clean condition. Do not allow dirt, dust, lint, or other contaminants
to accumulate on the truck. Keep the truck free from leaking oil and grease. Wipe up all oil spills.
Keep the controls and floorboards clean, dry, and safe. A clean truck makes it easier to see
leakage and loose, missing, or damaged parts, and helps prevent fires. A clean truck runs cooler.
The environment in which a lift truck operates determines how often and to what extent cleaning
is necessary.
For example, trucks operating in manufacturing plants that have a high level of dirt, dust, or lint(for
example, cotton fibers or paper dust) in the air or on the floor or ground, require more frequent
cleaning. The radiator especially may require daily air cleaning to ensure correct cooling.
If air pressure does not remove heavy deposits of grease, oil, etc., it may be necessary to use
steam or liquid spray cleaner.
※
Lift trucks should be air cleaned at every PM interval, or more often if necessary. Lift trucks should be air cleaned at every PM interval, or more often if necessary.
Use an air hose with special adapter or extension, a control valve, and a nozzle to direct the air
properly. Use clean, dry, low pressure, compressed air. Restrict air pressure to 207 kPa (30 psi),
maximum (OSHA requirement).
Wear suitable eye protection and protective clothing when air cleaning. Never point the air Wear suitable eye protection and protective clothing when air cleaning. Never point the air

Air clean the mast assembly, drive axle, radiator- from both counterweight and engine side,
engine and accessories, drive line and related components, and steering axle and cylinder.
8) 8) CRITICAL FASTENER TORQUE CHECKS CRITICAL FASTENER TORQUE CHECKS
Fasteners in highly loaded(critical) components can quickly fail if they become loosened. Also,
loose fasteners can cause damage or failure of the component. For safety, it is important that the
correct torque be maintained on all critical fasteners of components that directly support, handle, or
control the load and protect the operator. (SEE SECTION 8. SPECIFICATIONS)
Critical items include:
·Drive axle mounting
·Cabin
·Drive and steering wheel mounting
·Tilt cylinder mounting and yokes
·Counterweight mounting
·Mast mounting and components
Torque specifications are in your service manual.
9) 9) LIFT CHAIN MAINTENANCE LIFT CHAIN MAINTENANCE
The chain system on the mast was designed for safe, efficient, and reliable transmission of lifting
force from hydraulic cylinder to the forks. Safe use of your truck with minimum down time depends
on the correct care and maintenance of the lift chains. Most complaints of unacceptable chain
performance are a result of poor maintenance. Chains need periodic maintenance to give
maximum service life.
Do not attempt to repair a worn chain. Replace worn or damaged chains with a set (LH & RH). Do not attempt to repair a worn chain. Replace worn or damaged chains with a set (LH & RH).
Do not piece chains together. Do not piece chains together.
