How to Perform Planned Maintenance 7-27
Section 7. Planned Maintenance and Lubrication
CAUTION
!
CAUTION
!!
Wear suitable eye protection and protective clothing
when air cleaning. Never point the air nozzle at anyone.
Air clean the upright assembly, drive axle, radiator—from both
counterweight and engine side, engine and accessories, driveline
and related components, and steer axle and cylinder.
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.
Critical items include:
• Drive axle mounting
• Overhead guard
• Drive and steer wheel mounting
• Tilt cylinder mounting and yokes
• Counterweight mounting
• Upright mounting and components
Torque specifications are in your Service Manual.
Lift Chain Maintenance
The chain system on the upright 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.
WARNING
!
Do not attempt to repair a worn chain. Replace worn or
damaged chains. Do not piece chains together.
