Before You Operate Your Lift Truck iii
Before You Operate Your Lift Truck
...Be Prepared
Lift trucks are specialized machines with unique operating
characteristics. They require specific instructions and rules for safe
operation and maintenance. CLARK lift trucks are built to take hard
work, but not abuse. They are built to be dependable, but they are
only as safe and efficient as the operator and the persons
responsible for maintaining them.
Safety Standards
Your CLARK lift truck is designed and built to be as safe and efficient
as today’s technology can make it. As manufactured, it meets all the
applicable mandatory requirements of ANSI B56.1 Safety Standard
for Powered Industrial Trucks. In addition, all standard trucks
conform to Underwriters Laboratories requirements for the type
designation shown on the truck capacity plate. Each truck is also
furnished with certain safety devices—horn, for example—as
standard equipment.
ANSI B56.1, the standard for lift truck operation, includes rules about
operation, selection, training, supervision, and maintenance. We
suggest that owners, operators, and supervisors read this standard.
See “Safety Standards” in Section 6 for more information.
Safe Operation
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 is not properly trained
• Operator is not experienced with lift truck operation
• Basic safety rules are not followed
• Lift truck is not maintained in safe operating condition.
For these reasons, CLARK wants you to know about the safe
operation and correct maintenance of your lift truck. Clark provides
this Operator's Manual to help.
This manual is not a training manual, however. It is a guide to help
trained and authorized operators safely operate their lift trucks. It

iv Before You Operate Your Lift Truck
emphasizes and illustrates the correct procedures, but it cannot
cover every possible situation which may result in an accident. You
must watch for all hazards in your work areas and avoid or correct
them. While it is important that you know and understand the
information in this manual, you must also know and follow your
company safety rules! Be sure that your equipment is maintained in a
safe condition. Do not operate a damaged truck. Practice safe
operation every time you use your lift truck.
Remember, before you start operating this lift truck, be sure that you
understand all operating procedures. It is your responsibility, and it is
important to you and your family, to operate your lift truck safely and
efficiently. Be aware that the Federal Occupational Safety and Health
Act (OSHA) and state laws require that operators be completely
trained in the safe operation of lift trucks. If you think you need
training, ask your supervisor.
Safety and Planned Maintenance
Regular maintenance and care of your lift truck is essential for your
safety. A faulty lift truck is a potential source of danger to the
operator, and to other personnel working near it. Proper
maintenance is also important for economy and utilization. As with all
quality equipment, keep your lift truck in good operating condition by
following the recommended schedule of maintenance.
A lift truck should be examined by the user on a daily basis to be sure
it is safe to operate. Do not make any repairs to this truck unless you
have been trained in safe lift truck repair procedures and are
authorized by your employer.
In addition to the daily user inspection, CLARK recommends that a
planned maintenance and safety inspection program (PM) be
performed by trained and authorized personnel. Inspections,
adjustments, and repairs done during the PM increase the life of
components and reduce unscheduled downtime. The PM can be
scheduled to meet your particular application and lift truck usage.
Your CLARK dealer is prepared to help you implement a PM
program with trained service personnel who know your lift truck and
can keep it operating safely and efficiently.
