OIL
Use a premium quality 4-stroke motor oil to ensure
longer service life of your vehicle. Use only oils that
meet API service classifications SG and that
have a viscosity rating of SAE15W/40. If oil with a
rating of SAE 15W/40 is not available, select an
alternative according to the chart.
ENGINE COOLANT
Since antifreeze also has corrosion and rust-inhibiting properties, always use coolant containing antifreeze,
even if the atmospheric temperature does not go below the freezing point.
It is suggested that the freezing point of antifreeze should be 5
℃
lower than the lowest ambient temperature
where the vehicle is used.
Recommended Coolant: -35
℃
antifreeze, corrosion-resistant, high boiling point coolant
Warning!
Coolant is poisonous. Never drink it. Store it properly.
Caution: DO NOT mix coolant with that of other engines.
3.2.4 BREAK-IN PROCEDURES
During manufacturing only the best possible material are used and all machined parts are finished to a very
high standard. It is still necessary to allow the moving parts to “BREAK-IN” before subjecting the engine to
maximum stresses. The future performance and reliability of the engine depends on the care and restraint
exercised during its early life. Refer to the following break-in engine speed recommendations.
For better performance and durability, a new engine requires a run-in time of 20 hours as under:
0~10 Hours:
Avoid continuous operation above half throttle. Allow a cooling off period of five to ten minutes after every hour
of operation. Vary the speed of vehicle from time to time. Do not operate it at one set throttle position.
10~20 Hours
Avoid prolonged operation above 3/4 throttles. Rev the vehicle freely but do not use full throttle at any time.
Note: Keep the daily maintenance during the run-in time and eliminate the troubles, if any. After 20h run-in time,
do the maintenance according to the owner’s manual for normal operation of the UTV.
