A Message to Operators
The CLARK OSQ is a mobile multipurpose elevated platform vehicle that
is designed to e󰀩ciently pick and transport goods in the warehouse or
storeroom, assist in overhead maintenance, and other related tasks. It is to
be used indoors on clean, level surfaces only. Do not use on mezzanines
or balcony areas.
Its function and operation is not like a car or ordinary vehicle. It requires
specic instructions and rules for safe operation and maintenance.
The safe operation of this vehicle is of primary importance to CLARK. Our
experience with vehicle accidents has shown that when accidents occur
and people are injured or killed, the most common causes are:
• An improperly trained operator
• An inexperienced operator, unfamiliar with vehicle operation
• Basic vehicle safety rules NOT being followed
• The vehicle NOT maintained to a safe operating condition
For these reasons, CLARK wants you to know how to safely operate and
properly maintain your OSQ.
This manual is designed to assist you in operating your vehicle safely.
This manual shows and describes correct safety inspections and import-
ant general safety rules and hazards of vehicle operation. It shows and
explains the special components and features of your specic vehicle and
their functions. The correct operating procedures are shown and explained.
Illustrations and important safety messages are included to provide a clear
understanding. A specic section detailing proper maintenance and correct
lubrication is included for the vehicle service technician.
This operator’s manual is not a training manual. It is a guide to help trained
and authorized operators safely operate their vehicle by emphasizing and
illustrating the correct procedures. This manual cannot cover every possible
situation that could result in an accident. You must be aware of possible
hazards in your specic work area and make sure to correct or avoid them.
It is important that you know and understand the information in this manual
and that you understand and follow your company's safety rules. Make sure
that your vehicle is maintained to a safe, working condition. Do not operate
a damaged or malfunctioning vehicle. Practice safe operation every time
you use your vehicle.

v
Let's join together to set high standards in safety!
Remember, that before you begin operating this vehicle, make sure you
understand all correct driving procedures. It is your responsibility to operate
the vehicle safely and e󰀩ciently.
Be aware that the Federal Occupational Safety and Health Act (OSHA)
and state law, requires operators to be trained and certied in the safe
operation of material handling vehicles. It is an OSHA requirement that an
inspection of the vehicle be performed prior to every shift. If you have not
been certied (or require recertication training) to operate or inspect your
vehicle, notify your supervisor.
CLARK vehicles are designed and built to handle hard work, but not abuse
from the operator. They are built to be dependable, but are only as safe and
e󰀩cient as the operator(s) and person(s) responsible for maintaining them.
Do not make any repairs to this vehicle unless you have been properly
trained and authorized to perform safe vehicle repair.
For any repair, maintenance, or any other service work concerning your
vehicle, please contact your CLARK dealer.
Only use CLARK original spare parts to guarantee trouble free functionality
and optimum performance of your vehicle.

Introduction
Foreword
CLARK welcomes you to the growing group of professionals who own, op-
erate, and maintain CLARK vehicles. We take pride in the long tradition of
quality products and superior value the CLARK name represents. This manual
will familiarize you with the safety, operation, and maintenance information
concerning your new CLARK OSQ. It has been specially prepared to help
you use and maintain your CLARK vehicle in a safe and correct manner.
Your CLARK OSQ has been designed and built to be as safe and e󰀩cient
as today’s technology can make it. As manufactured, it meets all the appli-
cable mandatory design and construction requirements of the ANSI / SAIA
A92.6 - 2006 (R2014) American National Standard for Self-Propelled
Elevating Work Platforms.
Safe and productive operation of your vehicle requires both skill and knowl-
edge 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 skills required, the operator must
become familiar with the construction and features of the vehicle and how
they function. The operator must understand its capabilities and limitations,
and ensure that it is maintained to a safe working condition.
Routine Servicing and Maintenance
Regular maintenance and care of your vehicle is not only important for econ-
omy and utilization reasons; it is essential for your safety. A faulty vehicle is
a potential source of danger to the operator, and other personnel working
near it. As with all quality equipment, keep your vehicle in optimal operating
condition by following the recommended schedule of Planned Maintenance.

vii
Operator Daily Inspection — Safety and Operating
Checks
Your vehicle should always be examined by the operator, prior to driving,
to make sure it is safe to operate. The importance of this procedure is
described in this manual with a brief illustrated review and later with more
detailed instructions. Your CLARK dealer can supply you with copies of a
helpful Operator's Daily Checklist.
Planned Maintenance
In addition to the Daily Inspection, CLARK recommends that a Planned
Maintenance (PM) and safety inspection program be performed by a
trained and authorized mechanic on a regular basis. This PM will provide
an opportunity to make a thorough inspection of the safety and operating
condition of your vehicle. Necessary adjustments and repairs can be done
during the PM, which will increase the life of components and reduce
unscheduled downtime (increased productivity) and increase safety. The
PM can be scheduled through your CLARK dealer to meet your particular
application and vehicle usage.
The procedure for a periodic Planned Maintenance program covers inspec-
tions, operational checks, cleaning, lubrication, and minor adjustments. These
are outlined in this manual. Your CLARK dealer is prepared to help you with
a Planned Maintenance program by o󰀨ering trained service personnel who
know your vehicle and can keep it operating safely and e󰀩ciently.

The rst section of this manual is devoted to a review, with illustrations and
brief messages, of general safety rules and the major operating hazards you
may encounter while operating a vehicle. Next, you will nd descriptions of
the components of your specic vehicle model and how the instruments,
gauges, and controls operate. Then, you will nd a discussion of safe and
e󰀩cient operating procedures, followed by instructions on how to tow a
disabled vehicle. The later sections of the manual are devoted to mainte-

procedures in this manual. Understand how all the gauges, indicator lights,
and controls function. Please contact your authorized CLARK dealer about
any questions you may have about your vehicle’s features, operation, or
manuals.
Operate your vehicle safely; careful driving is your responsibility. Drive
defensively and think about the safety of other personnel who are working
nearby. Know your vehicle’s capabilities and limitations. Follow all instruc-
tions in this manual, including all IMPORTANT, CAUTION, WARNING, and
DANGER messages to avoid damage to your vehicle and to avoid any
harm to yourself or others.
It is an OHSA requirement that this Operator's Manual and the Manual of
Responsibilities be permanently attached to your vehicle. Keep these on
the vehicle as a reference for anyone who may operate or service it. If the
vehicle you operate is not equipped with either of these manuals, inform
your supervisor to obtain a replacement to be reinstalled to the vehicle.
