Troubleshooting
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 or an unopened service
valve. 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 carburetor as viewed from the operator's position. The screw is bright steel and 1/4"
in diameter with a Phillips head on it. 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: .
(1) Pad is off center. Remove and reinstall.
(2) Pad Driver is cracked. (Possibly from striking a curb or bolt in the floor) Replace at once with a new part.
(3) Bearings in Front End Assembly are worn. Place machine on its side where the muffler is mounted. 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.
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, 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 department 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 Tensioner. As a new belt wears in, it naturally stretches a bit and the
tensioner will begin to rattle. Place the buffer on its side (with the muffler down) and reset by taking up the
slack in the belt and tighten the Tensioner.
6.
STARTER BARELY TURNS THE ENGINE OVER or THE SOLENOID JUST CLICKS ON 12 VOLT 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 under the frame at the rear of the buffer. The positive post is the one with the RED cable
attached to it. Follow the instructions 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 BEGINS TO BACKFIRE REGULARLY, SUDDENLY - Check the sparkplug boots.
One 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. The engine should now run smoothly. IF IT DOES NOT contact our customer service
department for further assistance.
