Clarke Propane Floor Burnisher Carb-Gard Operation, Recommended 20 Hour Maintenance Items

ENGLISH EN

Maintenance And Adjustments

(c)Apply a thin coat of engine oil to the seal of the oil filter.

(d)Install the filter by turning it clockwise until the seal contacts the mounting surface of the engine.

(e)Then turn the filter by hand(s) 3/4 turn more.

(f)Run the engine at a slow idle speed for 2 minutes and check the oil filter and drain line for leaks.

6.Adjusting Pad Pressure -

(a)Tilt the machine back as you would to change the pad.

(b)To increase the pad pressure, move the wheels towards the rear of the machine. To do this, disconnect the hairpin from the clevis pin. Slide the clevis pin out and move the wheel to the back hole in the wheel caster. Reinsert the clevis pin and attach the hairpin.

(c)To decrease pad pressure, use the same proce- dure and move the wheel towards the front of the machine.

Recommended 20 Hour 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 20 hour oil change interval. Oil changes more frequent than 20 hours will give even longer engine life. In any case, always use 30HD or 10W30 engine oil with all of the following ratings: SF, SG,

CC.The various engines have different oil sump capaci- ties. Make sure the oil level is maintained at the "FULL" level.

Recommended 100 Hour Maintenance

The dust control filter must be changed every 100 hours.

Recommended 200 Hour Maintenance

The paper carburetion intake filter must be changed every 200 hours. 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 flashing. It will continue flashing 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 flashing.

(a)If the engine is idling, then the YELLOW "Idle" LED will begin flashing. 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 flashing 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 flashing 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 flashing.

(b)If the RED service LED flashes 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-Garb continuously monitors CO output. If the CO output drops, the service LED will stop flashing. If the CO output rises, it will start flashing again. ONLY after it continuously flashes for 1 minute will it shut down the engine.
