Lift trucks are specialized machines with unique operating character-
istics, designed to perform a specific job. Their function and operation
is not like a car or ordinary truck. They require specific instructions and
rules for safe operation and maintenance.
Safe operation of lift trucks is of primary importance to CLARK. Our
experience with lift truck accidents has shown that when accidents
happen and people are killed or injured, the causes are:
• Operator not properly trained
• Operator not experienced with lift truck operation
• Basic safety rules not followed
• Lift truck not maintained in safe operating condition
Forthesereasons,CLARKwantsyoutoknowaboutthesafeoperation
and correct maintenance of your lift truck.
This manual is designed to help you operate your lift truck safely. This
manualshowsand tells youaboutsafetyinspectionsand the important
general safety rules and hazards of lift truck operation. It describes
the special components and features of the truck and explains their
functions. The correct operating procedures are shown and explained.

derstanding. A section on maintenance and lubrication is included for
the lift truck mechanic.
