suitable size.
(1)There muse be a tight stationary foundation for the engine to avoid vibrations or
movement when the engine is running.
(2)Make sure that the centering position of the output shaft is properly aligned.
(3)If use the belt the pulley drive the engine, the size of the belt pulley should be in

(4)Please confirm whether the shaft hole of the belt pulley and the size of keyway match the
output shaft. Make sure not pack the keyway in to key by force. Otherwise may cause the accident.
Tighten the bolt of output shaft correctly. If the engine emits the black smoke in running, you must
reselect the diameter of the belt pulley.
(5)It is important to guarrantee that the belt tightness is moderate. If the belt is passed tight, it
will cause the engine starting difficult, still will arouse the premature worn out of the belt, even

may shorten the life of the engine. Follow the breaking-in procedures during the first 20 hours.
The operator must follow the following items:
a.Operate the engine for 5 minutes after starting for the first time. Keep the low load and low
speed until the engine hot, make sure not to operate the engine neither in no load of the low speed
nor in full load of the high speed.
b.Avoid overload
The engine can’t be full load running during breaking-in period. It can carry on breaking-in
according to 3000r/min,about 50% of load.
c.Change the lube oil regularly
