Foreword
This Operator’s Manual should help you to make the best use of your
CLARK Tow Tractor. Read through the instructions carefully and
follow the given procedures strictly. Acquaint yourself with the
controls and in particular observe all the safety regulations. Carry out
all maintenance and care work at the recommended time intervals.
CLARK Tow Tractors are characterized by their easy-maintenance
design. You will therefore be able to carry out this work in a short
time and without too much effort.
Regular maintenance and care of your Tow Tractor is recommended
not just on economic grounds, but because a faulty Tow Tractor
represents a source of potential danger.
In addition you should observe all Federal, State and Local
regulations which provide inspections at set intervals of time.
For any checkup, repair, maintenance and all other work concerning
your Tow Tractor, please contact your CLARK dealer. Here, specially
trained service personnel will be glad to help you at any time. Should
you desire to carry out maintenance, repair and all other work on
your Tow Tractor yourself, you can of course obtain all required
spare parts and all necessary materials from your CLARK dealer.
Please note: Only original CLARK spare parts guarantee the trouble
free functioning and optimum economy of your Tow Tractor. Original
CLARK spare parts are the best for your Tow Tractor. With their
dimensional stability as well as their high material quality due to
continuous and strict quality control, they correspond to those parts
used in the series production of our Tow Tractors.
Finally we would like to draw your attention to the fact that any
secondary damages due to improper handling, insufficient
maintenance, wrong repairs or the use of other than original CLARK
spare parts waive any liability by CLARK.

Operator’s Manual
You must be trained and authorized to operate a Tow Tractor.
Summary of Safe Operating Procedures
1. Do not operate this Tow Tractor unless you have been trained and
authorized to do so. Read all warnings and instructions in the operator’s
manual of this truck.
2. Do not operate this Tow Tractor until you have checked it’s condition. Give
special attention to tires, horn, lights, battery, brakes, steering mechanism,
and guards.
3. Operate tractor only from designated operating position. Never place any
part of your body outside of the confines of the tractor. Do not cary
passengers.
4. Make sure the tow coupling is secure.
5. Do not handle unstable or loosely stacked loads. Use special care when
handling long, high or wide loads to avoid losing the load, striking
bystanders, or tipping the tractor. Loads on trailers must be evenly
distributed and secure.
6. Do not overload the tractor. Check the capacity plate for load weight. The
safe capacity of a tractor-trailer is its stopping ability, not its potential towing
ability.
7. Start, stop, travel, steer and brake smoothly. Slow down for turns and on
uneven or slippery surfaces that could cause the tractor to slide or overturn.
Violent application of brakes is dangerous and may cause “jack-knifing” the
trailer.
8. When making a turn, allow for “corner-cutting” of the trailer.
9. When moving in reverse direction with a trailer, get assistance if vision is
obstructed. Moving in reverse direction with more than one trailer is not
recommended.
YOU can prevent accidents
First: Learn safe operating rules and your company rules.
Next: Read your Operator’s Manual. If you do not understand
it, ask your supervisor for help.
Learn about the unit you operate.

10. Make sure correct tire pressures are maintained.
11. Before driving over a dockboard or bridge plate, make sure it is correctly
secured. Drive carefully and slowly across the dockboard or bridge plate,
and never exceed its rated capacity.
12. Do not run over objects on the traveled surface.
13. Use special care when operating on ramps - travel slowly, and do not
angle or turn.
14. If a tractor must be parked on an incline, put chocks at the wheels.
15. Observe applicable traffic regulations and YEILD the right-of-way to
pedestrians. Slow down and sound horn at cross aisles and wherever vision
is obstructed.
16. Make a report of all accidents involving personnel, building structures
and equipment to the correct authority.
17. Before getting off the tractor, neutralize the travel control and set the
parking brake. When leaving the tractor unattended, turn the ignition switch
Off.

Safety Regulations
1. The Tow Tractor
Use in accordance with the regulations.
• Tow Tractors may only be
used in accordance with the
regulations, following these
operating instructions.
• Tow Tractors are designed to
tow loads.
• If a Tow Tractor is to be used
for other purposes, permission must be obtained from
CLARK, in writing, and if necessary from the supervisory
authorities responsible, in order to prevent hazards from
arising.
Stability
• CLARK Tow Tractors are stable in the working positions and
when driving, if used with due care and attention and
observing the maximum permissible loads.
• The trailing capacity of your CLARK Tow Tractors should
never be surpassed. It would endanger its braking capacity.

1-2
Safety Regulations
2. Inspection
Inspection prior to bringing into first use
• The Tow Tractor must be
checked as to its functionality
prior to putting it into opera-
tion. The working area to be
used must be inspected as to
its ground conditions (carry-
ing capacity, flatness, suffi-
cient width).
Regular and statutory inspections
• Tow Tractors must be regularly checked by trained and
authorized service personnel. CLARK recommends an
annual check-up based on an average operational perfor-
mance.
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 permission, the warranty service shall not be pro-
vided. For instance, the modifications which may void the
warranty include those that may negatively affect the perfor-
mance, durability and safety of the truck due to addition of
unauthorized electrical devices (lamp, black box, electrical
instrument, communication equipment, etc.), braking sys-
tem, steering system, vision improvement system and
detachable attachment device that were not mounted when
the equipment was shipped out of the factory.

• Only trained and authorized
personnel may be charged
with driving a Tow Tractor.
Please also observe all State
and Federal laws and regula-
tions.
• Please read this Operator’s
Manual and understand the
contents carefully.
• We strongly recommend that
you wear safety clothes
suited for your work. Any
wide or loose clothing must
be avoided. Always wear a
hard hat, safety shoes and, if
required, safety glasses.
• Never drive your Tow Tractor

he position of the tSafety Regulations
The working area
Operating aisles
• Never drive in areas which
are closed to Tow Tractors,
but only use aisles cleared for
Tow Tractors operation. Trav-
eling aisles and loading areas
must be clearly identified and
free of obstacles. Tow Trac-
tors shall only be used on
routes without sharp curves,
excessive slopes and gades which are too narrow or too
low. Watch the road surface - it must be sufficiently smooth
and free of bumps. Please further observe all State and Fed-
eral regulations.
Hazard areas
• Tow Tractors which are to be used in flammable or explosive
environments must be specially equipped for this purpose.
The hazard areas must be identified accordingly.

1-5
Safety Regulations
Getting ON/OFF the Equipment
• It is very dangerous to jump on or off the equipment.
• To get on or off the equipment, stop the equipment and use
guide rail or steps to keep from losing your balance.
• The general rule is therefore that the operator shall always
dismount when facing the truck.
• When getting on or off the equipment, do no grab the gear
lever.
• Keep the guide rail or steps clean and well-maintained.

1-6
Safety Regulations
When driving
Driving conduct
The operator shall comply with internal instructions on in-
house traffic regulations and the relevant road traffic
regulations on public roads. The speed of the Tow Tractor has
to be adjusted to local conditions. For example, the operator
shall drive slowly in bends, at and in narrow passageways or
gates, when driving through swinging doors, at blind
intersections or on uneven surfaces. He always shall keep a
safe braking distance from vehicles or persons in front of him
and he must always have his truck under control. Sudden
stops, quick turns, overtaking at dangerous or blind
intersections shall be avoided.
Tow Tractors shall not be put in motion when the operator is
not assuming the proper operating position in the operator's
seat.
Whilst driving, it is forbidden, amongst other things:
• To put arms or legs outside the truck
• For the operator to lean over the edge of the Tow Tractor
• To move from one truck to another or to fixed parts of a
building.
The operator shall bring his truck to a standstill as soon as
possible if the steering equipment is defective.

1-7
Safety Regulations
Braking
The driving speed must be selected so that there is always an
adequate braking distance in front of the truck. It should be
noted in this respect that the pure braking distance increases
at a higher rate of speed and that the drive wheels may spin or
the truck may overturn in case of sudden braking.
Gradients
• Always reduce your speed and drive with special care on
grades.
• Always keep the load fixed if you drive on grades.
• With restricted visibility always seek assistance when travel-
ling on grades.
• Do not turn when going up or down a grade. Never drive
diagonally across the grade. The truck can easily roll over in
this case.
• Grades should always have a sufficiently rough surface. For
smooth, and even travel avoid any load contact with the
ground.
• Grades used by trucks shall not exceed the limits specified
by the manufacturer.

1-8
Safety Regulations
Climatic condition for Operation
• Maximum ambient temperature, short term(up to 1h) : +104 °F
(+ 40
°C).
• Average ambient temperature for continuous duty :
+ 77 °F
(+ 25
°C).
• Lowest ambient temperature :
- 4 °F (- 25 °C) (in normal out-
door condition),

• Relative humidity : in the range 30 % to 95 % (non-condensing)
Tips for Operation according to the Weather
1) Hot Weather
Driving in hot weather impairs driving ability and work effi-
ciency. Take rest at regular intervals.
2) Cold Weather
Remove the ice, snow or frost on the weather enclosure
window before start operation. (If weather enclosure
installed)
Take utmost care when driving on icy surface.
Do not step on slippery surface when getting in or out of
the equipment.
Use an ice removing device equipped with a handle and
ladder to remove ice. snow or frost.
Replace worn tire immediately. Especially, worn tires can
cause serious accident on icy ground.
Do not apply abrupt braking or starting on icy ground.

3) Rainy Weather
If forklift truck is to be operated outdoors during rainy con-
ditions, make sure cab is in place to prevent damage to
electrical components
Behavior during operation

and all warning signs. Always
behave as if traveling on pub-
lic roads. Reduce the speed
of your Tow Tractor and use
the horn near corners,
entrances, exits and near
people.

1-10
Safety Regulations
When driving
• Avoid any abrupt starting, excessive traveling speeds and
sudden directional changes.
• Select the driving speed so that sufficient stopping distance
is always available. It must be remembered that the net
stopping distance increases by approximately the square of
the speed and that sharp braking of the Tow Tractor can
cause the drive wheels to slip and the truck to tip over. Brak-
ing on curves further increases the danger of the Tow Trac-
tor tipping due to the tilting moment which occurs.
• Reduce speed before curves and ramps, in narrow pas-
sageways, on wet roads and restricted visibility.
• Always look in the driving direction. No parts of the body
should extend outside the truck.
• Always keep a sufficient distance from other vehicles so as
to be able to stop in time in case of danger.
Safety of people
• Always make sure that there
is nobody within the hazard-
ous area of your Tow Tractor.
Ask these people to leave the
area immediately.
• Do not let other persons ride on the truck, on trailers.

1-11
Safety Regulations
Tow Tractor tip over
Tow Tractors can be tipped
over if not operated properly.
Teach your operators that there
are a number of things they
must watch for that can cause a
truck to tip over.
• Slow down before turning. Go
into and out of turns slowly,
using a slow rotation of the steering wheel.
• Do not move unstable loads.
• Do not turn on down- and up-slopes
• Drive careful and slowly at ramp edges or steps
• You may find that you have some long runs where you oper-
ate the truck empty, close to its top speed. Slow down before
turning.

1-12
Safety Regulations
The operator must wear personal safety devices and follow the
instructions for safety to prevent serious personal injury if the
equipment overturns.
1. In the event your Tow Trac-
tor is equipped with a
weather enclosure, wear
safety belt. Never jump off
the equipment.
2. Hold the steering wheel
firmly.
Stiffen your legs to support
yourself.
3. Lean against the opposite
side wall, as shown in the
figure.
