ii A Message to CLARK Lift Truck Operators
A Message to CLARK Lift Truck Operators
Lift trucks are specialized machines with unique operating
characteristics, 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
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.
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.
A Message to CLARK Lift Truck Operators iii
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
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; it is also an OSHA
requirement that a machine inspection be performed before every
shift. If you think you need training in 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 efficient 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.
CAUTION
!
This forklift burns fuel, which will produce exhaust gases
that are harmful to humans. They include carbon monox-
ide, carbon dioxide, nitrogen oxides and hydrocarbons.
The amounts of each of these gases will vary, depending
on a number of related factors. With the correct fuel,
proper tuning of the system by technicians and adequate
ventilation, this truck can produce emissions that are con-
sidered safe for indoor use. Of the four gases, carbon
monoxide poses the greatest threat. Carbon monoxide
symptoms may vary with individuals, depending on
breathing rate, the amount of work or exercise being per-
formed at the time of exposure, and the physical state of
the subject. In case of working in an enclosed area, the
area should be well ventilated. We recommend the forklift
not be operated in a small enclosed area for long periods.
To maintain the emission levels to a normal level, custom-
ers are requested to follow the maintenance schedule. A
truck using diesel fuel is not recommended indoor use.

Introduction
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
efficient as today’s technology can make it. As manufactured, it
meets all the applicable mandatory requirements of ANSI / ITSDF
B56.1 Safety Standard for Powered Industrial Trucks. Each truck is
also furnished with equipment to help you operate safely; for
example, load back rest, parking brake, safety restraint system, seat
belts 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. To 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 are 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 efficiently.
Modification of the truck prohibited
Unauthorized modification of the truck is not permitted, and, in case
that a problem has occurred due to a modification without permis-
sion, the warranty service shall not be provided.
For instance, the modifications which may void the warranty include
those that may negatively affect the performance, durability and
safety of the truck due to addition of unauthorized electrical devices
(lamp, black box, electrical instrument, communication equipment,
etc.), braking system, steering system, vision improvement system
and detachable attachment device that were not mounted when the
equipment was shipped out of the factory.
