Maintenance And Adjustments
3.
Belt replacement.
Tilt the machine on its side
(observing the following precautions) and block
securely.
**KAWASAKI twin cylinder - Do not tilt the machine on
its nose as this is where the carburetor is located. It is
okay to turn this model on either its left or right side.
(a) Remove pad.
(b) Use a suitable wrench to secure the top of the
shaft and spin off the pad driver and remove it
from the machine.
(c) Remove old belt carefully and completely.
(d) Install new belt and adjust the pressure of the
Lovejoy tensioner.
(e) Reinstall pad driver.
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 200 Hour Maintenance
Return machine to authorized service center for overall
checkup.
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 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, contact your sales or service
representative.
2.
EXCESSIVE VIBRATION -
Look for the following
possibilities:
(1) Pad is off center. Remove and reinstall.
(2) Pad Driver is bent or cracked. (Possibly from
striking a curb or bolt in the floor.) Replace
immediately with a new part only.
(3) Bearings in Front End Assembly are worn.
P
lace
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.
(4) 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 for instruc-
tions 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,
contact your sales or service representative.
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.
Place the buffer on its side (with the muffler down)
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 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 BACKFIRES
LOUDLY AND REGULARLY SUDDENLY -
Check
the sparkplug 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 your sales or service representative.
