REGULAR MAINTENANCE
MAINTENANCE AND ADJUSTMENT OF THE CHAIN
Regular performing of maintenance is one of the best methods of contributing to the
prolonging of the service life of the machine, ride safety and the lowering of expenses.
Loosen the rear wheel axle and the check nuts of the adjustment bolts. Adjust the
recommended slack of the chain to 5 mm, by even tightening / loosening of the ad-
justment bolts on both sides. Tighten the wheel axle. Tighten the check nuts of the
adjustment bolts against the movable blocks. It is suitable to measure the given mea-
surement (x) using a slide gauge (it must be the same on both sides of the fork).
The chain must be regularly lubricated which increases its service life and decreases
the operational noise. The chain must be lubricated every time after riding on a wet
road. We recommend to lubricate it with a special oil in a spray. If it is necessary to
replace the chain then also inspect both of the sprocket-wheels. If they are worn then
they must be replaced with the chain at the same time.
A - Before each ride:
- Inspect the cables / hoses and the effectiveness of the breaks.
- Inspect the lubrication and the adjustment of the chain drive. The chain should
have a slack of 5 mm.
- Always clean the minibike and maintain it in a clean state after every use.
Do not use aggressive cleaning products.
- After 1 hour of riding always wash the air lter in gasoline and smear oil on to it for
air lters. The same applies after every ride in the rain.
- After 1 hour of riding clean the clutch with compressed air and perform an inspe-
ction of the adjustment of the clutch levers.
- Inspect the condition of the brake pads. The lining thickness cannot be less than 1 mm.
Perform the basic adjustment of the brakes.
- Inspect the cooling system for leaks and the amount of the cooling liquid in the
leveling reservoir - must be 1/2 the volume of the reservoir.
- Inspect the condition of the clutch lining - its thickness cannot be less than 1 mm!
Perform an adjustment of the clutch levers.
- Make a visual inspection of the entire minibike. Replace all the damaged parts
(worn, deformed) with new ones.
- Inspect the tires’ air pressure.
- Inspect the tightness of all the bolts and nuts - see the tightening torques table.
B - Always following 5 hours of operation:
- Thoroughly clean the oat chamber of the carburetor.
