slippery surfaces such as ice,go slow and be very
cautious in order to reduce the chance of skidding or
sliding out of control.
Never oper ate a QU AD in f ast flowing water. Remember
that wet brakes ma y ha v e reduced stopping ability.Test
your brakes after lea ving water.lf necessary. apply them
several times to let friction dry out the linings.

TIRES

Check tire pressure frequently with the air pressure
gauge.
Tire should be inflated to the recommended pressure.
Recommended:
FRONT: 20kpa, (0.2 kgf/ cm2), 2.8 psi
REAR: 20kPA, (0.2 KGF/CM2), 2.8 psi
Minimum:
FRONT:17Kpa, (0.17 kgf/cm2), 2.4 psi
REAR: 17Kpa, (0.17 kgf/cm2), 2.4 psi

The pressure should be checked when the tires are
"cold" before running the vehicle.

Tire wear limit

When the tire groove decreases to 3mm (0.1" ) due to
wear. replace the tire.

OPERATION INSPECTION

Inspect your vehicle e v ery day before you run it. It only
takes a fe w minutes to chec k and might sa ve your live .
Check oil level in crankcase The oil level should be
between the maximum and mini mum marks.

Oil hole

-16-

Check brake operation. If any problem cannot be
corrected by the adjustment, hav e the QU AD inspected
by leader.
Check tires condition and pressure as recommended.
Check throttle for smooth opening and closing. lt must
return back to idle position when released.
Check engine stop switch for good function.
Check steering for proper wheels turning.
Check nuts,bolts and other fastners.

-17-

STARTING PROCEDURE

1. Par king the vehicle on a level surface and lock the
parking brake.

2. Turn the fuel valve to “ON”.

3. Move the engine stop switch to “ON”.

4. Grasp the lever on the right handbar or left.

5. Push the start button on the left handlebar.

6. Push the throttle lever slightly.

RIDING

Begin by finding a safe area free of obstacles with a
level surface. Always keep your feet on the footrest
during operation.
Under normal riding conditions it is not necessar y to
touch the ground for balance.
Then:

1.Start the engine.

2. After the engine has been warmed up, release the
parking brake The vehicle is ready for riding.

3. Increase engine speed by opening the throttle gra­dually.

RUN-IN

During the first two weeks of riding.run your new vehicle
tenderly. Don't run as fast as to approach maximum
rpm.
This run-in process will greatly enhance the long term
power and the life of the engine.

-18-

PARKING

1. Parking at a level surface.

2. After stopping the v ehicle ,turn the engine stop switch
to OFF position.

3. Lock the parking brake at the left handlebar.

TURNING

It is essential that this skill shall be learned at first at
low speed. The rider must learn to move his weight
and control the throttle to allow the rear tires to get the
turn. When turning, the wheel on the outside of the
turn must travel a wider radius and thus a greater
distance than the inside wheel. As the rear axle does
not permit a differing rate of wheel rotation. It is not
enough to merely steer this vehicle into a turn. To turn
steer in the direction of the turn, leaning your body to
the inside of the trun. While supporting your weight on
the outer footrest. Use the throttle to maintain power
throughout the turn. Incorrect turning may cause the
front wheels to slide straight ahead. If this should
occur.close the throttle and stop. Avoid braking or
accelerating until you hav e regained directional control.
Be careful to avoid skids while traveling on slippery
terrain.

-19-

Climbing uphill

Practice riding at first on gentle slopes. Try more difficult
climbs only after you have developed your skill. Avoid
excessive steep hills or slopes. With slippery or loose
surface in rough terrain. Keep both feet on the footrests.
When climbing a hill, shift your weight forw ard, proceed
at a steady rate of speed and throttle opening. If you
are unable to continue up the hill, dismount vehicle on
the uphill side Phypsically turn the vehicle around and
then descend the hill.

Crossing through shallow water.

QUAD 50 can be used to cross slow moving, shallow
water of up to a maximum of 16 cm (6.3") in depth.
Entering the water where there is no sharp drop off,
rocks or other. Remember that wet brakes may have
reduced stopping ability. Test your brak es after leaving
water until you have regained proper braking ability.

SPARK PLUG

Standard spark plug; TORCH LDE6T

1. Disconnect the spark plug cap.

2. Clean up dirt from around the spark plug base.

3. Remove the spark plug.

4. Inspect the plug electrodes for wear .lf the electrodes
and insulator tip appear unusually fouled or burned.
change a new one. Discard the spar k plug if there is
apparent wear or if the insulator is cracked or chipped.

5. The spark plug gap shall be kept in 0.6-0.7mm (0.24"-

0.28"). lf adjustment is necessary,bend the side electrode
carefully.

6. Install the spark plug, scre w it in finger tight and then
tighten with the plug wrench another 1/2 turn to com­press the washer.

AIR CLEANER

The air cleaner will accumulate dust and must be clea­ned periodically. lf riding in very dusty area. The filter
must be cleaned more frequently.
To clean the filter:

1. Remove the air cleaner cover.

2.Take out the filter from the air cleaner case.

3. Wash the filter element in a non-flammable or high
flash-point solvent.Soak the element in clean oil until
saturated, then squeeze out the excess oil.

-22-

4. Let the filter element dry and reinstall it.

Air cleaner

CARBURETOR AND IDLE SPEED ADJUSTMENT

The carburetor is a vital part of the engine and requires
very sophisticated adjustment. Most adjustments should
be left to the leader who has the professional knowl­edge and experience to do so.

BRAKE

Check the brake cable for kinks or signs of wear that
could cause sticking or failure. Lubricate the brake
cable with a available cable lubricant to prevent pre­mature wear or corrosion.
Make sure that the brake arm, spring , rod and fasteners
are in good condition.
Ask your leader to replace the pads when they are
almost in contact with the disc plate.

-23-

Rear axle housing

DRIVE CHAIN

Sometimes,it needs to lubricate the chain. The SAE
80 or 90 gear oil is recommended.
The chain will loosen with use, how to adjust chain.

1) Release two rear axle housings nuts and bolts (total
six nuts and six bolts).

2) Release two Rear axle housings simultaneously,
make sure equal degrees rotation of those and keep
the chain vertical suitable distance.

3) Tighten those bolts and nuts.

THROTTLE CABLE

Inspect throttle cable condition and operation. Replace
the cable if it has become worn or kinked.
Lubricate the cable with oil to prevent premature w ear
or corrosion. Adjustment can be made with the adjuster
beside the throttle lever.
Loosen the lock nut and turn the adjuster.

-24-

The free play should be maintained at 5-10mm (0.197-

0.254).

BATTERY

When reinstalling the battery, be sure to connect the
red cable to the positive (+) lead and the black cable
to the negative (-) lead.
When the battery no longer can hold a charge, replace
it. The battery should be replaced every three years as
a normal service.

Check the lev el of battery fluid and see if the terminals
are tight.
Add distilled water if the fluid level is low. The level
should be between the upper and lower level marks.
