OPERATION INFORMATION
Engine break-in as a result of proper care during the first
hours of operation of a new or rebuilt engine results in the
ideal fitting of all internal moving metal parts, which is
essential for top engine performance. For controlled engine
break-in.
1. Operate the equipment as it is intended to be operated.
However, for the first 3 hours, if possible, operate the
equipment at about half the available engine power,
occasionally operating at full engine power for brief
periods. Also, if possible, avoid prolonged low-speed,
low-power operation during engine break-in.
2. Proper engine oil is especially critical during break-in
because of the higher engine temperatures that can be
expected. See RECOMMENDED ENGINE OIL.
Change the oil if it is not appropriate for the ambient
temperatures during the break-in periods. See Table 1,
Figure 1 Page 6.
3. Check the oil level twice a day or after every 4 hours of
operation during the first 24 hours of operation.
4. Change the oil and oil filter after the first 5 hours of
operation.
OPERATION IN DUSTY CONDITIONS
1. Keep the engine cooling fins and flywheel air inlet screen
and precleaner (filter) clean.
2. Perform air cleaner maintenance more often than
normal - as required.
3. Change the engine oil more often than normal. See
Table 2, Page 10.
OPERATION IN HOT WEATHER
Pay particular attention to the following items when
operating the engine in temperatures above 100°F (38°C):
1. Keep the engine cooling fins and flywheel air inlet screen
and precleaner (filter) clean: See to it that nothing
obstructs air flow to and from the engine.
2. Check the oil level more frequently.
3. Change the oil more often than normal. See Table 2,
Page 10.
4. Make sure the engine oil viscosity is appropriate for
the ambient temperature and change the oil if
necessary. See Table 1, Figure 1 page 6.
OPERATION IN COLD WEATHER
Pay particular attention to the following items when
operating the engine in temperatures below freezing.
Make sure the engine oil viscosity is appropriate for the
ambient temperatures and change the oil if necessary. See
Table 1. If the temperature drops before you have the chance
to change the oil, warm up the engine by moving the
equipment into a heated space before attempting to start
the engine or change oil.
After engine has reached operating temperature while pad
is still off the floor. Before lowering burnishing head, adjust
throttle to operating speed. After slowly lowering machine
to floor, place hands lightly on the handle and allow the
machine to create the floor pressure. Bearing down and
pushing hard will lead to premature belt problems and
operator fatigue. For smoother turns and greater
maneuverability, buff aisles from the right side first.
CAUTION: DO NOT RUN MACHINE FOR MORE THAN 15
SECONDS IN ONE SPOT OR BURNING WILL OCCUR.
IDLING AND STOPPING THE MACHINE
If for any reason the machine needs to be idled for short
periods, simply tilt machine back on its rear caster and
release throttle bail into Idle Position. Machine will now idle
safely.
(CAUTION: DO NOT IDLE BUFFER ON REAR
CASTER FOR MORE THAN TWO MINUTES. This will
raise the emissions level.)
To stop machine tilt back on rear caster, turn valve on
propane tank off, and allow fuel in the lines to be used up.
FOR EMERGENCY SHUT OFF ONLY : turn off ignition
switch. Electric start models: use emergency stop switch
on right side of control panel.
STORAGE
Only authorized and properly trained personnel should have
access to propane tanks and machine.
Making sure tank valve is closed, remove tank from buffer.
Local Fire Codes may require storing tank in separate
location.
We recommend this, as well as following
Local Fire Codes.
Store machine and tank away from objects that may fall
and damage them.
Never store tank or buffer near open flame or heat producing
devices.
Make sure machine is cleaned properly prior to storage.
To prevent damage pad holder, the pad SHOULD remain on
machine during storage.
EMERGENCY STOP
Turn ignition key to OFF position.
Units with emission control device and clutch. Release bail
on handle to activate kill switch.
