Changing coolant
The coolant should be changed periodically to ensure long engine
life.
- Wait for the engine to cool completely.
- Put the QUAD in a horizontal position.
- Remove the radiator cap.
- Place a bowl under the drain plug and drain the fluid from the
radiator and the engine, by unscrewing the drain plug which is in
the lower part of the water pump cover. Immediately wipe or wash
off any coolant that spills on the frame, engine, or wheels.
WARNING
Coolant on tyres will make them slippery and can cause an accident.
-Inspection of the coolant. If white marks are visible in the fluid, this
means that the aluminium parts of the coolant system are corroded.
If the fluid is brown the parts made of steel or iron in the system are
rusted. In both cases clean the system.
- Check the cooling system for damage, loose joints, or leaks.
- Install the water pump cover drain plug with the specified torque
shown in the table. Replace seals with new ones.
Tighten bolts (see table of tightening torques)
Water pump plug: 9 Nm.
- Fill the radiator up to the edge and fit the cap on the radiator.
- Check the cooling system for leaks.
- Start the engine, warm up the engine, and then stop it.
- Check the coolant level after the engine cools down.
AIR FILTER
CAUTION
The air filter must ALWAYS be cleaned after going out with the Quad.
Dirt may enter the engine and damage it severely.
WARNING
A blocked air filter allows dirt to enter the carburettor and keeps the
throttle open. This could cause an accident.
A blocked air filter, restricts the entry of air to the engine, increases
fuel consumption and reduces engine power and damages the spark
plugs.
NOTE
There is a test hose in the lower part of the air filter casing. If
dust or water enter the hose, empty it and clean the air filter
element and casing.
