Operator's Manual (EN) - DC Propane Burnisher - 17 -
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.

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.

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.
Trouble Shooting
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.
