WARNING
LETHAL EXHAUST GAS
NEVER RUN THE ENGINE
IN A CLOSED BUILDING
OR CONFINED AREA
Exhaust gases contain poisonous carbon
monoxide. Carbon monoxide is odorless,
colorless, and can cause death if inhaled.

SAFETY
General Safety Information
Keep hands, feet, strings and ties away from all moving
parts while the machine is in operation. The exhaust system
gets very hot so keep hands, clothing and any items that can
burn away from the engine, engine manifold, and muffler
while hot.
PowerBuff machines are built tough and durable,
however do not abuse the machine and the machine won’t
abuse you. With proper care and maintenance this unit will
give you trouble free operations for the years to come.
Warning: Lethal Exhaust Gases
Engine exhaust gases contain poisonous carbon
monoxide. Carbon monoxide is odorless, colorless,
tasteless, and can cause death if inhaled. Avoid
inhaling exhaust fumes and never run the engine in a
closed building or confined area without proper
ventilation.
Although LPG burns more efficiently and emits
less carbon monoxide than gasoline, some carbon
monoxide is produced. Avoid inhaling exhaust gases -
especially over prolonged periods of time. Do not
allow engine to run unattended.

CARBON MONOXIDE DETECTOR
The “CO” carbon monoxide detector detects carbon monoxide before
it reaches dangerous levels. This detector is a must for those who run
propane powered equipment in or around enclosed areas.
• The CO Detector is for everyone’s protection against Carbon
Monoxide Poisoning.
• Effective for 30 days after package has been opened
• Mount with self-adhesive strip on the side of machine handle or
locate it near the operator’s collar.
• If the orange disk on the detector changes to gray or black -
your Carbon Monoxide Levels are at a Dangerous Level. See
(1) & (2)
(1) If the orange disk changes to gray or black you must turn
your buffer off immediately and return it to your nearest
authorized PowerBuff Inc. distributor for an emissions test.
(2) Do Not Restart the machine until the emissions have been
checked and corrected.
This is for your protection as well as your customers. CO detectors
are a must for safe operation and maximum efficiency of your
equipment.
For replacement CO detectors, contact your PowerBuff Inc.
distributor. Ask for the carbon monoxide detector or part P1125.

Tank Storage and Maintenance
We at PowerBuff Inc., use the Worthington gas
cylinders designed for vapor withdraw. The fuel lockoffs,
regulators, and engines are also designed for vapor
withdrawal. “Fuel freeze-ups” or “frozen regulators” are a
result of liquid propane being introduced into the system. To
prevent these “freeze-ups” from occurring follow this
important procedure:
(1) Do not overfill - the best gauge is a scale - never
allow tank to weigh over 36 pounds for an
aluminum tank and 43 pounds for a steel tank.
(2) Store tanks outside in a well-ventilated area.
(3) Store tanks in the upright position (valves up).

INSTRUCTIONS
BEFORE STARTING THE MACHINE
Before any operation should begin, you first should read your Engine Operation
Manual and your Owner’s Manual.
Your machine is shipped ready for your operation, however there is no fuel in the
tank. When having the tank filled, you must make sure the tank is never over
filled.
The best way to do this is to tell the filling station to weigh the tank full. On an
aluminum tank, it should weigh no more than 36 pounds and on a steel tank no
more than 43 pounds.
Adjustable Handle: Adjust the handle for comfortable operation. Use two 3/4”
wrenches and loosen handle. Adjust to comfortable height and re-tighten bolts to
40-50 ft/lbs.
• Check Oil Level: Starting the engine without the proper amount of oil will
cause severe engine damage. Always keep the engine oil level between the
full and add marks on the dipstick. Do not loosen oil fill cap or remove dipstick
while engine is running.
o Park your PB 17-V-Twin on a level surface.
o Turn the oil fill cap counter clockwise and then lift from the fill tube.
o Wipe the dip stick clean and push it back into the oil fill tube until the cap
seats and then withdraw it to check: the oil level. (Do not screw cap on to
check oil). Add if necessary. If the oil level is low, add API Class SG or SH
oil having a SAE viscosity grade appropriate for the expected
temperatures as indicated in the Operators Manual.
o Important Note: DO NOT OVERFILL
o Replace oil cap.
• Inspect fuel hoses and fittings for leaks. Repair leaks immediately.
• Look and listen for exhaust leaks. Have all leaks repaired before operating.
• Check the carburetor filter and air filter for debris. Clean and replace if
necessary.
• Connect fuel hose to tank by screwing the hose fitting to tank. You must
tighten all the way down to make fuel connection. Turn tank knob slowly until
you hear the flow of fuel into fuel system.

INSTRUCTIONS
STARTING THE ENGINE
The PB 17-V-Twin is equipped with a 12 volt starter and a key switch
start.
(1) Start the Extreme Strip machine with the brushes in the running
position, flat on the floor.
(2) Open propane tank valve (turn counterclockwise).
(3) Put throttle cable into the “slow” position.
Note: If starting is difficult, you can place throttle in the “fast”
position, and after the engine starts, back off to the slow
position before the centrifugal clutch engages.
(4) Turn the ignition - start switch to the “start” position and hold it
there until the engine starts. Do not crank for more than 20
seconds at a time and wait at least one minute between tries
when cranking. See troubleshooting guide if the engine does not
start after several tries.
(5) After engine starts, set throttle so that the centrifugal clutch will
not engage until the engine has warmed up. Do not operate
machine until the engine has warmed up sufficiently. ( 3 to 5
minutes )
STOPPING THE ENGINE * * *
1. Turn propane tank valve to the closed position (turn clockwise)
and allow the engine to continue running until it runs out of fuel.
This can be done with the centrifugal engaged or not engaged.
* * *
2. Turn key to the off position.
***In an emergency, immediately turn
the key to the off position.
Backfiring may occur when using this method.
