Clarke Propane Floor Burnisher manuel dutilisation Trouble Shooting

When troubles occur, be sure to check the simple causes which at first may seem too obvious to be considered. For example, a starting problem could be caused by fuel starvation due to an empty propane cylinder, an un- opened service valve, or a loosened fuel quick coupler. If you don't check for this, starter burnout could result.

1.KAWASAKI - "SURGING IDLE" - To smooth out the engines' idle characteristics, adjustment is provided by an idle screw on the lower left side of the carbure- tor as viewed from the operator's position. The screw is bright steel and 1/4" in diameter with a Phillips head on it. To gain access to the engine throttle screw, pop the black snap-in plug off of the top of the engine cowling. Rotating the screw clockwise will increase the idle speed and this should cure the "surging idle". IF IT DOES NOT, call our customer service department for assistance.

2.EXCESSIVE VIBRATION - Look for the following possibilities:

(a)Pad is off center. Remove and reinstall.

(b)Pad Driver is bent or cracked. (Possibly from striking a curb or bolt in the floor.) Replace immediately with a new part only.

(c)Bearings in front end assembly are worn. Tilt the machine back as you would to replace the pad. Grip pad driver and move up, down and from side to side to check for slack in the bearings. If this is the case, then to effect a proper repair, the bearings should be replaced and possibly the shaft.

(d)Check to see if the bolts on shaft housing are tight. Look to see if the nuts, bolts and spacers on the Flex Coupler Assembly are all in place and tight.

3.ENGINE STARTS AND IDLES, BUT WILL QUIT AS THE THROTTLE IS ADVANCED - It is possible that the propane tank's service valve is faulty. To check for this, close the valve completely and then reopen very slowly while you listen for a "click" when the gas begins to travel through the valve. If you hear this very slight noise, then what is happening is the valve is only partially opening. This allows enough gas through to start and idle the engine, but not enough for full throttle operation. As the throttle is increased, allowing more air to enter the intake, the engine will quit from fuel starvation. Call your dealer or the factory for instructions on where to have the service valve replaced. Meanwhile, to get by, you can continue to open the service valve until you don't hear a "click" and then the engine will run normally. IF IT DOES NOT, call our customer service depart- ment for further assistance.

4.THE BUFFER SEEMS TO RUN WELL BUT DIES DOWN WHEN THE PAD IS PLACED ON THE FLOOR OR SOON THEREAFTER - Check for the same problem as in #3.

5.EXCESSIVE NOISE FROM UNDER BUFFER - If this problem has developed after use of the machine from new, then the first place to check is the Lovejoy tensioner. As a new belt wears in, it naturally stretches a bit and the tensioner will begin to rattle.

Tilt the machine back as you would to change the pad and reset by taking up the slack in the belt and tighten the Lovejoy tensioner.

6.STARTER WILL HARDLY TURN THE ENGINE OVER or THE SOLENOID JUST CLICKS ON 12 VOLT OPTION MODELS - The battery is likely low in charge. This can be remedied by recharging the battery using a 12 volt battery charger at 4-12 amperes. The battery is located inside the control box, located directly in front of the propane tank. The positive post is the one with the RED cable attached to it. Follow the instruc- tions that came with the battery charger. REMINDER: this will continue to happen unless the buffer's engine is run for sufficient time between starts to recharge the battery.

7.KAWASAKI V-TWIN ENGINE BACKFIRES LOUDLY AND REGULARLY SUDDENLY - Check the spark- plug boots. One of them is likely cracked, possibly due to contacting a corner of a shelf or a door frame. Remove the sparkplug lead from the sparkplug and replace the boot with a new one. The engine should now run normally. IF IT DOES NOT contact our customer service department for further assistance.
