PM Program
A planned maintenance program of regular, routine
inspections and lubrication is important for long life and
trouble-free operation of your lift truck. Make and keep
records of your inspections. Use these records to help
establish the correct PM intervals for your application
and to indicate maintenance required to prevent major
problems from occurring during operation.
PM Report Form
As an aid in performing and documenting your PM
inspections, Clark has prepared a “GAS LPG or DIESEL
PLANNED MAINTENANCE REPORT” form. Copies of
this form may be obtained from your Clark dealer. We
recommend that you use this form as a checklist and to
make a record of your inspection and truck condition.
A checkmark or entry is made on the PM Report Form
when the PM is performed. Please note the special
coding system for indication the importance of needed
repairs and/or adjustments.
Do not make repairs or adjustment unless
authorized to do so.
Safety Precautions
•
Remove jewelry (watch, rings, bracelets, etc.)
before working on truck.
•
Disconnect the battery ground (-) cable from the
engine before working on electrical components.
•
Wear safety glasses. Wear a safety (hard) hat in
industrial plants and in special work areas where
protection is necessary or required.
Visual Inspection
The objective of the visual inspection is to be sure that all
components of the truck are:
1)
in place
2)
attached securely
3)
in a safe and proper operating condition
Do not use your hand to check for hydraulic leakage.
Use a piece of cardboard or paper to search for leaks.
Escaping fluid under pressure can penetrate the skin
causing
serious
injury.
Relieve
pressure
before
disconnection hydraulic or other lines. Tighten all
connections before applying pressure. Keep hands and
body away from pinholes and nozzles which eject fluids
under high pressure. If any fluid is injected into the skin,
it must be surgically removed within a few hours by a
doctor familiar with this type injury or gangrene may
result.
