MAINTENANCE AND ADJUSTMENTS
Recommended 8 Hour Break In (50 hour there after) Maintenance Items -
>Change engine oil.
>Check pad driver for loose parts.
>Check belt for wear or slippage.
>Check engine pulley for tightness.
>Check wheel bolts.
>Check engine mount bolts.
>Check handle bolts.
>Check for leakage of engine oil at the various seals.
Recommended Oil Change Intervals
Do not exceed the oil change interval. Oil changes more frequent than 50 hours will give even longer engine life. In any case, always use 30HD or 10W30 engine
oil with all of the following API ratings: SJ or higher. Make sure the oil level is maintained at the "FULL" level.
Recommended 200 Hour Maintenance
Return machine to authorized service center for overall checkup.

CARB GARD OPERATION

Carb Gard is a warning device to alert the operator that the engine needs to be serviced.
1. Upon starting the engine, the GREEN "Alert" LED will begin fl ashing. It will continue fl ashing for 3 minutes. This allows the engine and the
oxygen sensor (mounted in the exhaust manifold) enough time to warm up. During this time, it is okay to operate the burnisher.
2. After 3 minutes, the Alert LED will stop fl ashing.
(a) If the engine is idling, then the YELLOW "Idle" LED will begin fl ashing. This allows the engine to idle for up to 2 minutes.
(b) After 2 minutes, the engine will shut down and the idle LED will remain solid to notify the operator why the machine shut down. (Note: If
this occurs, simply turn the key switch to OFF. This will reset the Carb Gard. Restart the engine normally to continue operation).
(c) If at any time before the 2 minute countdown, the engine is revved up to full throttle, the LED will stop fl ashing and the Carb Gard will
being monitoring the oxygen sensor.
(d) If the engine is allowed to slow back down to the idle position, the idle LED will again start fl ashing for another 2 minutes.
NOTE: Every time the engine is revved up and allowed to slow down, the 2 minute countdown restarts itself.
3. Once the engine is revved up, the Carb Gard begins monitoring the oxygen sensor for carbon monoxide (CO).
(a) If at any time during full throttle the Carb Gard senses a higher than normal CO output, it will activate the RED "Service" LED and it will
begin fl ashing.
(b) If the RED service LED fl ashes continuously for 1 minute, then the engine will shut down and the RED service LED will remain solid to
notify the operator why the engine shut down.
NOTE: Carb Gard continuously monitors CO output. If the CO output drops, the service LED will stop fl ashing. If the CO output rises, it will
start fl ashing again. ONLY after it continuously fl ashes for 1 minute will it shut down the engine.
