III. OPERATION
Provide and use ear protection during operation.
Never let an untrained person operate or
perform repairs on the machine. They may hurt
themselves, damage the floor or the equipment.
Engine speed not to exceed 3400 RPM.
This machine is not suitable for picking up
hazardous dust.
Do not use on surfaces with a gradient
exceeding 2%.
IV. STOPPING THE ENGINE
Turn the propane tank valve clockwise to a closed
position and turn the key OFF.
NOTE: The exhaust system will be very hot and
takes several minutes to cool, so keep yourself
and all materials clear.
V. PROCEDURES
Follow machine (straight ahead) at moderate
walking speed. Keep moving.
• Do not operate the machine in one location
for more than a few seconds — it will
damage — “burn” the finish.
• When operation is completed remove tank
and store in a secure, protected off site
(preferably outdoor) location.
• Do not use for scrubbing operations.
• Never tilt back machine to maintenance
position while engine is running.
• Never reach under protective shroud when
engine is running.
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: Displays total run hours when
machine is off.
Tachometer: Indicates engine RPM during
operation.
Service Alert: Change oil after first 8 hours of
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. Always
wear a face shield, safety glasses and protective
clothing when working around a battery! The
gases can be explosive and the acid is highly
corrosive to metals, cloth and ALL HUMAN
TISSUE (skin, eyes, etc.) If the battery post(s) are
corroded, remove the wires and clean posts and
wires. Applying some axle grease on the posts of
the battery after they are cleaned will slow down
the battery corrosion process.
If nothing obvious is noted, a more detailed
investigation is warranted. Before any such
troubleshooting begins, the following things
should be done:
a. Replace propane LPG tank with one from a
machine that runs.
