Lift trucks are specialized machines with unique operating characteristics, designed to perform a specifi c job. Their function and operation
is not like a car or ordinary truck. They require specifi c 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
For these reasons, CLARK wants you to know about the safe operation
and correct maintenance of your lift truck.
This manual is designed to help you operate your lift truck safely. This
manual shows and tells you about safety inspections and 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.
Illustrations and important safety messages are included for clear understanding. A section on maintenance and lubrication is included for
the lift truck mechanic.
A Message to CLARK Lift Truck Operators
iii
The operator’s manual is not a training manual. It is a guide to help trained
and authorized operators safely operate their lift truck by emphasizing
and illustrating the correct procedures. However , it cannot cover every
possible situation that may result in an accident. You must watch for
hazards in your work areas and avoid or correct them. It is important that
you know and understand the information in this manual and that you
know and follow your company safety rules! Be sure that your equipment is maintained in a safe condition. Do not operate a damaged or
malfunctioning truck. Practice safe operation every time you use your
lift truck. Let's join together to set high standards in safety.
Remember , before you start operating this lift truck, be sure you understand all driving procedures. It is your responsibility , and it is important
to you and your family, to operate your lift truck safely and effi ciently .
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; it is also an OSHA requirement that a machine
inspection be performed before every shift. If you have not been trained
(or need refresher training) operating or inspecting your lift truck, ask
your supervisor.
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 effi cient as the
operator and the persons responsible for maintaining them. 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.

CLARK welcomes you to the growing group of professionals who
own, operate, and maintain CLARK lift trucks. We take pride in the
long tradition of quality products and superior value the CLARK name
represents. This manual familiarizes you with safety, operating, and
maintenance information about your new lift truck. It has been specially
prepared to help you use and maintain your CLARK lift truck in a safe
and correct manner.
Your CLARK lift truck has been designed and built to be as safe and
effi cient as today’s technology can make it. As manufactured, it meets
all the applicable requirements of ANSI/ITSDF B56.1 Safety Standard
for Powered Industrial T rucks. Each truck is also furnished with equipment to help you operate safely; for example, load back rest, parking
brake and horn are standard equipment.
Safe, productive operation of a lift truck requires both skill and knowledge
on the part of the operator. The operator must know, understand, and
practice the safety rules and safe driving and load handling techniques
described in this manual. T o develop the skill required, the operator must
become familiar with the construction and features of the lift truck and
how they function. The operator must understand its capabilities and
limitations, and see that it is kept in a safe condition.
Routine Servicing and Maintenance
Regular maintenance and care of your lift truck is not only important
for economy and utilization reasons; it 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. As with all quality equipment, keep your
lift truck in good operating condition by following the recommended
schedule of maintenance.
Introduction
vii
Operator Daily Inspection — Safety and Operating Checks
A lift truck should always be examined by the operator, before driving, to be sure it is safe to operate. The importance of this procedure
is emphasized in this manual with a brief illustrated review and later
with more detailed instructions. CLARK dealers can supply copies of
a helpful “Drivers Daily Checklist.”
Planned Maintenance
In addition to the daily operator inspection, CLARK recommends that a
planned maintenance and safety inspection program (PM) be performed
by a trained and authorized mechanic on a regular basis. The PM will
provide an opportunity to make a thorough inspection of the safety and
operating condition of your lift truck. Necessary adjustments and repairs
can be done during the PM, which will increase the life of components
and reduce unscheduled downtime and increase safety. The PM can
be scheduled to meet your particular application and lift truck usage.
The procedures for a periodic planned maintenance program that
covers inspections, operational checks, cleaning, lubrication, and
minor adjustments are outlined in this manual. Your CLARK dealer is
prepared to help you with a Planned Maintenance Program by trained
service personnel who know your lift truck and can keep it operating
safely and effi ciently .
viii
This manual is a digest of essential information about the safe operation,
the features and functions, and explains how to maintain your lift truck.
