STARTING
STARTING A COLD ENGINE
1. Before starting the engine for the
first time always check the oil level
as shown on page 10.
2. Turn the engine switch on.
3. Set the throttle lever on the
handlebar to the half-way
position.
11
Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]
Page 12
4. Move the choke lever on the
engine to the full choke position.
5. Turn the fuel valve lever to the on
position.
6. Ensure the engine switch is in the
on position.
7. Pull the handle on the recoil
starter slowly several times to help
fuel to flow into the engine’s
carburettor. Hold the handle firmly
and pull the cord out a short
distance until resistance is felt.
Now pull the handle firmly and
briskly and allow the cord to return
gently.
8. Do not let the cord snap back. If
necessary, pull several times until
the engine starts.
9. Allow the engine to run for several seconds to warm up, then gradually
move the choke lever to the OPEN position.
STARTING A WARM ENGINE
Restarting an engine that is already warm from previous running does not
normally require the use of the choke.
1. Ensure the engine switch is on.
2. Set the throttle lever on the handlebar at the half-way position.
3. Hold the handle on the recoil starter firmly and pull out a short distance
until you feel some resistance. Then pull the handle smoothly and briskly
and allow to return gently. Do not let the handle snap back. If necessary,
pull again until the engine starts.

OPERATING
CONTROLLING THE SPEED AND DIRECTION
1. After the engine warms up, move
the throttle lever to set the engine
speed.
2. Engage the required gear and
slowly press down the clutch
control lever to engage the drive.
3. If the gear does not engage
straight away, slowly release the
clutch lever and try again.
• The truck will now start moving.
• When the clutch control lever is released, drive will be disengaged
and the truck will stop automatically.
The gear selected is shown on the
label at the bottom of the truck.
• 3 x forward, neutral and reverse
4. The truck has the steering levers
on the handlebars. To turn right or
left, simply squeeze the
corresponding right or left steering
lever.
NOTE: The sensitivity of the steering
increases in proportion to the
speed of the truck and
weight of the truck. With the
load box empty, a light
pressure on the lever is all
that is needed to turn. When the truck is loaded, more pressure is
required.
The truck has a maximum load capacity of 300kg. However, it is advisable to
assess the weight of the load and adjust it according to the ground on which
13
Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]
Page 14
the truck will be used. Also, bear in mind the weight of the truck added to that
of the load.
Take extra care working over areas of rough ground use a low gear.
Avoid sharp turns and frequent changes of direction, in particularly on rough,
hard terrain with sharp, uneven points with a high degree of friction.
Take extra care when working in adverse weather conditions (ice, heavy rain
and snow) or on types of ground that could make the truck unstable.
If the truck is stopped on a steep slope, place a chock against one or more of
the wheels to prevent unexpected movement.
IDLE SPEED
Set the throttle lever to its SLOW position to reduce stress on the engine when
no work is being done.
• Lowering the engine speed will reduce fuel consumption and help
extend the life of the engine.
STOPPING THE ENGINE
1. Move the throttle lever to the slow
position.
2. Let the engine idle for one to two
minutes.
3. Turn the engine switch to the off
position.
4. Turn the fuel valve lever to the off
position.
Do not move the choke to stop the
engine.
To stop the engine in an emergency simply turn the engine switch to the off
position. Under normal conditions use the above procedure.

Page 15
MAINTENANCE
Proper maintenance and lubrication will help keep the truck in perfect
working condition.
CARE AND PREVENTIVE MAINTENANCE
Turn off the engine and let it to cool before touching engine components.
1. Inspect the general condition of the truck. Check for loose screws,
misalignment or binding of moving parts, cracked or broken parts and any
other condition that may affect its safe operation.
2. Remove all debris that may have accumulated in the truck. Clean after
each use if working in a dirty environment. Use a premium quality
lightweight machine oil to lubricate all moving parts.
3. Never use a pressure washer to clean your truck. Water can penetrate
areas of the machine and its transmission parts and cause damage to
spindles, gears, bearings, or parts of the engine. The use of pressure
washers will result in shortened life and reduce serviceability.
LUBRICATION
The gearbox is pre-lubricated and sealed for life at the factory.
With the engine stopped, remove the engine oil filler plug and check (with the
machine standing level) that the oil is between the upper and lower marks on
the dipstick as shown on page 10. Top up if required.
If changing the engine oil, it should be drained when the engine is hot and oil
will flow more freely. When it is fully drained, replace the drain cap and fill up
with new oil.
TYRE PRESSURES
Check the tyre pressures periodically to make sure they are properly inflated.
• The recommended pressure is 30psi for all tyres. Do not over-inflate.
CLUTCH ADJUSTMENT
As the clutch wears with long term
use the lever could develop a wider
operating range and become
harder to use. This means that it will
be necessary to adjust the cable.
Set the clutch lever to its original
position using the cable adjuster and
the locking nut.
15
Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]
Page 16
DRIVE BELT ADJUSTMENT
The drive belt tension can be
adjusted by means of the cable
pulling on the cam shown.
This in turn also operates the cable to
disengage the gearbox brake.
The drive belt can be seen after
removing the belt pulley cover. When
removing the belt pulley cover, take
care not to unscrew the spacer
shown from the engine. It must
remain fitted to the engine when
tensioning the belt.
The spacer prevents belt chatter
once the belt has been adjusted.
BRAKE CABLE ADJUSTMENT
When the drive belt tensioner is
adjusted it can alter the effectiveness
of the brake which could allow the
truck to move forward when starting.
ADJUSTING THE STEERING
If you have difficulty steering the
truck you will need to adjust the
steering levers with the adjusters
provided.
Slacken off the locknut and unscrew
the adjusters to eliminate the play in
the cable which can occur after
initial use and normal wear.
Take care not to unscrew the
adjusters too far or this will result in loss
of traction. Tighten the locknut when you are finished.

LONG TERM STORAGE
If you do not expect to use the truck for some time then the following tasks
should be undertaken before storing.
1. Empty the fuel tank completely by draining the fuel via the carburettor.
Place a container below the carburettor and use a funnel to avoid
spillage. Remove the carburettor drain bolt and sediment cup, then move
the fuel valve to the ON position. After all fuel has drained, re-fit the drain
bolt and sediment cup.
2. Start the engine and allow to run until it stops for lack of fuel. Ensure the fuel
cap is secure.
3. Remove the spark plug and pour several drops of oil into the cylinder.
4. Crank the engine slowly using the recoil starter in order to distribute oil
around the cylinder and piston, then replace the spark plug.
5. Carefully clean all parts, ensuring a film of oil covers any bare metal parts.
Use a brush to clean the cooling fins. Oil the linkage at the carburettor.
6. Store in a dry environment.
SERVICE AND REPAIRS
In the event of damage or broken components, replacements are available
from Clarke Parts & Service. The engine should be serviced by a qualified
technician. Please contact your CLARKE dealer for technical support.
