I. PREPARATION
A. Check that the suggested maintenance
schedule has been observed:
All machines are equipped with a multi-function
maintenance meter. The functions include the
following: hour meter, service alert and tachome
(See Engine Maintenance Meter Instructions on pg5).
B. Check the engine oil before every operation:
Make sure the machine is level when checking the
oil. Always take 2 readings of the dipstick before
adding oil. If the oil level is below the full mark, add
just enough oil to the engine to bring the oil level
up to the full mark. Never over fill. Follow the
guidelines in your Engine Owners Manual. Check
for
foreign material on the dipstick.
C. Properly fill and check your LPG tank and
all LPG fuel lines for leaks:
1. Every tank has been pressure and leak
tested. However, every time a tank is filled
and/or connected to the machine it should be
soap tested. All LPG lines must be pressurized
and every inch of line and connections must be
sprayed. If you find a leak, make the proper
repairs before operating th
NOTE: The connection and disconnection of
the LPG tank must be done in a well ventilated
area with NO source of ignition within 10 feet
(3 meters) from the point of connection.
2. Never over fill the LPG tank! The LPG tank
is designed to hold just 20 pounds of propane.
Make sure to weigh the tank as it is being
filled. The gross weight of a full tank should
not exceed 48 pounds. If while opera
machine, you notice frost forming on the LPG
lines or the regulator, your tank has been over
filled. If you continue to operate the machine
in this condition, damage will occur. The
excess propane in the tank must be removed
before normal operations resume. The
bleeding of a propane tank should be done in a
safe location outside the building. In some
cases the regulator must defrost before

D. Connecting the high pressure hose to the
LPG Tank:
Make sure the couplers are in line and screwed
together hand tight. If this is not done properly,
fuel will not pass through to the regulator. Never
complete the connection of the tanks to the
machine by using a wrench. Always do it by
hand. Listen for the rush of fuel to the lock-out
device when you open the tank valve. If you
hear this,

VI. MAINTENANCE
A. Machine & engine maintenance
1. Refer to engine manufacturer’s owners
manual and comply completely with the
instructions. Change the oil and filter according
to the Engine Owners Manual.
2. Keep a good service log on each machine
with the date, hour meter reading, type(s) of
service performed and the name of the person
who performed them.
3. Clean the entire unit after each use. When
cleaning the unit, check for possible loose nuts
and bolts.
4. The foam engine dust filter should be removed
and cleaned periodically by shaking out the
accumulated dust and rinsing with water and a
mild detergent. Squeeze out the excess water
(do not wring out). Allow the filter to air dry
before replacing. Failure to keep the engine dust
filter clean may result in engine overheating.
B. Engine maintenance meter
This multi-function meter acts as a preventive
maintenance tool, which benefits you with
increased fuel economy, less down-time and
longer engine life.
The meter’s displays are:
Hour Meter:
machine is off.
Tachometer:
operation.
Service Alert:
operation. Thereafter change oil every 50 hours.
The display flashes to alert you to lube and
change the oil at 25 hour intervals. The service
alert only flashes during operation and it warns
you to change the oil for only two hours. After the
two hours is reached, the alert will automatically
reset to the next 25 hour interval. Therefore, it is
recommended that a separate maintenance log
be kept to track oil changes.
Remember that being safe is a full-time, every
day job. Follow all information posted on the
machine and the LPG tank.
Never allow anyone to operate this machine
who has not read or cannot understand the
given instructions.
C. Troubleshooting the electrical system
1. Check all wire connections for obvious
problems. Remove LPG tank, then remove
battery box cover. Check all connections visibly
and physically. If any “loose”, damaged or
unconnected wires are noticed, replace or
repair as needed.
2. Check the battery posts and wires.
