PROPANE SAFETY INFORMATION
Facts About
Liquid Propane
Gas (LPG)
Facts About
Propane Tanks
As a fuel, propane gas is unmatched for both safety and dependability. It
has been used a a domestic household fuel for over half a century, and for
over thirty years as an internal combustion engine fuel.
Propane is a highly flammable fuel that is contained under pressure as a
liquid. Vaporized gas has a similar explosive force to gasoline and
mixtures as low as 2% LP gas to air may be ignited in a closed
environment. Care should be exercised to avoid escaping vapor as it can
freeze skin and cause frost bite. Vaporized fuel is heavier than air and will
collect in the lowest confined space available.
Propane tanks are constructed according to ASME or Federal DOT
#4ET20 pressure safety codes. Including the tank, all valves and fittings
are UL listed. Propane gas is noncorrosive and will not rust the inside of a
tank. Should the tank exterior become damaged or rusted, discontinue
use. DO NOT tamper with the tank gauges or safety relief valves. NEVER
use a tank not intended for use with a propane burnisher. DO NOT
substitute tanks that are used with a barbecue grill, etc. WerkMaster
recommends having propane tanks tested once a year by an authorized
National LP Gas Association propane dealer.
The fuel tank is supplied directly from the manufacturer and is void of fuel.
The tank must be purged at the time of the first fill. Local propane fuel
vendors should be familiar with this operation and will provide this service.
Recommended
Purge Procedures
WARNING
DO NOT attempt to repair the tank. Return the tank to your propane if
necessary.
!! ! ! !
New containers may contain vapor, air, or other contaminants. It is
essential that these be removed before filling the container and putting it
into service. Air in the container will cause abnormally high pressure, with
the result that the pressure relief valve may open. Air in the system is also
likely to cause a lean mixture, making ignition difficult. If a tank is
suspected of being depressurized or open to the atmosphere for a period
of time, it must be re-purged.
See an authorized propane dealer for proper purging of your new tank.
Symptoms of a non-purged propane tank:
Relief valve opens due to over-pressurized propane tank creating
•
hazardous situation
Moisture in the propane tank
•
Burnisher operates initially but shuts down when the fuel mixture
•
becomes too lean.
OPERATOR’S MANUAL

Filling Propane
Tanks
WARNING
ALWAYS have an authorized propane dealer fill your tank.
NEVER OVERFILL THE PROPANE TANK. ONLY FILL TO 80%.
OVERFILLING PROPANE TANKS IS HAZARDOUS. EXPANSION
MUST BE ALLOWED FOR.
FILL THROUGH THE SERVICE VALVE ONLY.
These machines use a 20 lb (9.1 kg) capacity aluminum or steel cylinder,
which meets the DOT4E240 standards. These standards are also listed
by UL. In addition, the steel cylinder meets meets European TPED
specifications and is CE compliant.
The engine and the fuel system on your WerkMaster machine are
designed to run on vapor propane NOT liquid propane. Liquid propane
and vapor propane are NOT interchangeable. Interchanging the fuel will
VOID THE WARRANTY.
Use a vapor withdraw cylinder NOT a liquid withdraw cylinder on this
machine. The use of a liquid withdraw cylinder on a vapor withdraw
system could freeze the regulator and create a fire hazard.
If the regulator freezes, stop the burnisher and take the tank outside and
inspect. Use gloves or pliers to open the bleeder valve and purge the tank
until only vapor is escaping.

Storing Propane
Tanks
Propane tanks should NOT be stores in buildings used by employees, the
public or frequented by anyone passing through.
When not in use tanks should always be stored outside in an upright position
in a secure, tamper-proof, steel mesh storage cabinet. The cabinet may be
located next to the building, but with at least five (5) feet (1.5 m) of space
between the cabinet and the nearest building opening (door or window).
NEVER store spare propane tanks in an enclosed van or trailer, or near
an open flame or heat-producing device..
PROPANE TANKS SHOULD ALWAYS BE INSTALLED, USED.
TRANSPORTED AND STORED IN AN UPRIGHT POSITION.
The National Fire Protection Association (NFPA) Standard for Storage and
Handling of LP Gas is the appropriate authority for safe propane use. A
copy of this publication is available through the National Fire Protection
Association (1.800.344.3555) or www.NFPA.org.
Storing Machine
Transporting
Machine
Store the machine in a dry location, temperature not to exceed 120º F
(50º C), away from objects that may fall and damage it, and away from
open flames or heat-producing devices.
NEVER store machine with propane tanks installed.
Make sure the machine is properly cleaned before storing.
When transporting a propane-powered machine with the propane tank
installed, the tank should be securely fastened and the service valve
closed. Any propane tanks not installed should be upright and securely
fastened to avoid movement and damage.
Check the propane tanks for over-filling BEFORE transporting; If overfilled, use the bleeder valve to vent the excess propane outside in a safe
area.
When loading onto or unloading off of a truck or trailer, turn the machine
OFF.
ONLY use a truck or trailer that will support the weight of the machine.
Block the wheels and tie the machine securely to the truck or trailer.
OPERATOR’S MANUAL

ENGINE EMISSIONS AND CARBON MONOXIDE SAFETY
DANGER
All engines powered by by LPG (Liquid Propane Gas), including this engine,
Carbon Monoxide (CO). it is a FATAL POSION gas that is colorless, odorless,
tasteless, and non-irritating. It is produced by incomplete combustion of
carbonaceous material such as LPG.
Failure to provide for proper venting of CO produced during the operation
of combustion powered engines may result in SERIOUS INJURY OR
DEATH to the operator and those in the contaminated area.
The effects of CO can experienced at different exposure levels,
depending on the health of the individual. Conditions that affect the
tolerance of the individual are smoking, age, temperature, humidity, and
other conditions.
Symptoms include lightheadedness, confusion, headaches, vertigo,
drowsiness, dizziness and nausea.
If the operator experiences any of these symptoms STOP USING THE
MACHINE IMMEDIATELY. Move to a well-ventilated area. If symptoms
persist, get medical attention.
CO Exposure
Limits
Methods to Reduce
the Risks of CO
Poisoning
Prolonged or high exposure to CO may result in vomiting, confusion, and
collapse in addition to loss of consciousness and muscle weakness; call
911 for emergency medical attention. If you have experienced these
symptoms DO NOT operate the machine or any other propane machine
until cleared by a doctor. Excessive exposure to CO may result in death.
All distributors, owners, and operators should be aware of the potential
effects of CO and the methods used to prevent over-exposure.
Please refer to OSHA, WCB or local workplace industry guidelines for CO
exposure limits.
Air Exchange and CO Diffusion
CO does not mix with air on its own. Air currents can “stir” the CO and
dilute the concentration values by mixing it with the available air. Stirring
can occur by walking around and with the use of fans and ventilation
systems.
Application Considerations
Consider the operation you are performing and the size of the area to be
worked. A low movement operation in a smaller area will increase the
build-up of the CO, while a much quicker operation over the same area
may not have the same potential for CO build-up.
Stirring or CO mixing MUST be forced by the use of fans in order to
reduce the high concentration of CO when activity is concentrated to a
smaller area while performing a low movement operation.
OPERATOR’S MANUAL
12
Air Quality Monitoring
Use of a monitor/detector is essential for the safe operation of any
equipment that has the potential to produce CO. See local regulations for
the approved monitors/detectors and their correct methods of use.
Room Size and Time Estimations
The concentration and volume of CO production, the size of the area, and
the amount of air exchange are factors involved with determining safe
time limits for operation in a specific room size.
The smaller the work area and the slower the movement, the greater the
build-up of CO. Fans MUST be used to stir the air and reduce the
concentration of CO.
Maintenance of Equipment
LPG engines are dependent on engine tune-ups and air filter
replacements. CO concentration (production) increases when the air to
fuel ration becomes fuel rich. Follow the recommended Maintenance
SChedule for the engine.
CO Safety Equipment Available
WerkMaster propane machines are equipped with a catalytic muffler and
an ACCU-Sense monitoring system on the Stealth and an AUTO-Sense
monitoring system on the Spectre to reduce the CO emissions and
promote a safer work environment.

ACCU-Sense
Emissions
Monitoring System
The engine throttle controls the engine speed. To increase the engine
speed, move the hand lever forward. For the idle position pull the lever
back.
The Stealth ACCU-Sense is an emissions monitoring device that monitors
the exhaust emissions and will shut the engine down if the emission levels
are too low or too high.
After engine starts, the YELLOW alert light will flash for a 3 minute warmup cycle of the ACCU-Sense system. The machine may be operated
during the warm-up period. After the warm-up cycle, the alert light will go
out. None of the ACCU-Sense lights will be illuminated as long as the
machine is running safely.
Any light that is on when the engine stops will remain illuminated for 20
seconds to indicate the reason for the machine shut down.
OPERATOR’S MANUAL
15
OIL: The light will come on when there is low oil pressure. If the engine
looses oil pressure, the engine shuts down until the condition is corrected.
The light comes on each time the engine is stopped.
TILT/IDLE: The light will come on when the machine is tilted to the pad
change position and the engine shuts down. If the machine is allowed to
idle for more than 4 minutes, the light flashes for 1 minute, then the
engine shuts down.
RED ACCU-SENSE SERVICE: If carbon monoxide levels exceed a preset level, the light will flash. The machine will shut down after the light
flashes continuously for 1 minute. If the machine does not operate
normally after the engine air filter is checked and cleaned, it must be
serviced by a qualified technician.
YELLOW ACCU-SENSE ALERT: If the light comes on during normal
operation, check and clean the engine air filter. Check the carburetor air
filter for holes, tears, or punctures and replace if damaged. If the light still
remains on, the machine must be serviced by a qualified technician.
OXYGEN SENSOR: If light comes on during normal operation, check the
oxygen sensor wire for a snug fit into the harness and for a snug fit of the
harness into the ACCU-Sense board. If the light still remains on, the
machine must be serviced by a qualified technician.
TURN GAS OFF: Light comes on to remind the operator to turn off the
gas after the engine shuts down.
BATTERY: The light comes on when the battery voltage is low indicating
the need to service the charging system.
The oxygen sensor must reach operating temperature before it will start to
send signals to the ACCU-Sense module. This warm-up period is
approximately 3 minutes. After the initial 3 minutes, the module will start
evaluating the signal from the oxygen sensor. If the module receives an
abnormal reading for a period of 1 minute, the unit will shut down.
If the machine is also allowed to idle for more than 4 minutes, an indicator
light will flash for 1 minute and then the engine will shut down. If this
happens, turn the key to the OFF position for several seconds to clear the
ACCU-Sense module and restart the machine.
Once the engine has started, advance the bail throttle to operating
position and start the operation. With the engine at full throttle, under load,
the signal from the oxygen sensor should be within the normal operating
ranges for safe operation.
If the engine’s air intake filter needs to be serviced, or an over-filled
propane tank has been installed by mistake, or there is a problem with the
fuel system that causes the oxygen sensor’s signal to be out of range,
ACCU-Sense will shut the unit down after 1 minute. The unit can be restarted after clearing the module by turning the key switch OFF. If
corrections have not been made to the unit, ACCU-Sense will continue to
shut the unit down until the problem is corrected.
OPERATOR’S MANUAL
16
Engines tend to go to a lean burn if allowed to idle for even short periods.
Even at high idle speeds most engines will continue to lean downward. it
is always best to shut the engine off when it is not being used to do work.
Remember, the engine is always creating emissions as long as it is
running.
The best manner to operate a unit equipped with ACCU-Sense is as
follows:
With the bail throttle in the idle position, turn the key switch to the
•
START position. Once the engine starts, advance the bail throttle to
the operating position.
When ready to stop operation, release the bail throttle. If the unit will not
•
be used within 45 seconds, turn the key switch to the OFF position, or
if the unit will not be returned to service within a few minutes it is best
to turn the gas valve on the tank off first and let the engine consume
all fuel that is in the lines. Once the engine dies, turn the key switch to
the OFF position.
When ready to restart, open the gas valve on the tank and turn the key
•
switch to the START position. Once the engine has started, move the
bail throttle to the operating position and return to operation.
SPECTRE
AUTO-Sense
Emissions
monitors the exhaust emissions and will shut the engine down if
the emission levels are too low or too high.
The Spectre AUTO-Sense is an emissions monitoring device that
Monitoring System
The monitor must receive a signal from the oxygen sensor in order to
function. The oxygen sensor must reach operating temperature before
it will start to send signals to the AUTO-Sense module. This warm-up
period is approximately 3 minutes. After the initial 3 minutes, the
module will start evaluating the signal from the oxygen sensor. If the
module receives an abnormal reading for a period of 1 minute, the
unit will shut down.
If the machine is also allowed to idle for more than 4 minutes, an indicator
light will flash for 1 minute and then the engine will shut down. If this
happens, turn the key to the OFF position for several seconds to clear the
AUTO-Sense module and restart the machine.
OPERATOR’S MANUAL
17
Once the engine has started, advance the bail throttle to operating
position and start the operation. With the engine at full throttle, under load,
the signal from the oxygen sensor should be within the normal operating
ranges for safe operation.
If the engine’s air intake filter needs to be serviced, or an over-filled
propane tank has been installed by mistake, or there is a problem with the
fuel system that causes the oxygen sensor’s signal to be out of range,
AUTO-Sense will shut the unit down after 1 minute. The unit can be restarted after clearing the module by turning the key switch. If corrections
have not been made to the unit, AUTO-Sense will continue to shut the unit
down until the problem is corrected.
Engines tend to go to a lean burn if allowed to idle for even short periods.
Even at high idle speeds most engines will continue to lean downward. it
is always best to shut the engine off when it is not being used to do work.
Remember, the engine is always creating emissions as long as it is
running.
The best manner to operate the machine is:
With the engine throttle in the SLOW position, turn the key switch to the
START position. Once the engine starts, advance the throttle to full
throttle FAST.
When ready to stop the machine, move the engine throttle to the SLOW
position. If the machine will not be used within 45 seconds, turn the key
switch to the OFF position, or if the machine will not be used within a few
minutes, it is best to turn the gas valve off first and let the engine consume
all fuel that is in the lines. Once the engine dies, turn the key switch to the
OFF position.
Hour Meter/
Tachometer
When ready to restart, open the gas valve on the tank, put the engine
throttle in the SLOW position and turn the key switch to the START
position. Once the engine has started, move the engine throttle to the
FULL position and return to operation.
The hour meter/tachometer records the number of hours the machine has
been powered ON. The hour meter reading is used to mark the
recommended maintenance intervals. It also displays the engine speed.
The meter displays hours when the machine is turned OFF and the
engine speed when the machine is turned ON.
