86343970 18HP LIGHTNING BURNISHER
3-5
PROBLEM
CAUSE
SOLUTION
The burnisher seems to run
well but dies down when
the pad is placed on the
floor or soon thereafter
To check for this, close the valve
completely and then reopen very slowly
while you listen for a "click" when the gas
begins to travel through the valve. If you
hear this very slight noise, the valve is
only partially opening. This allows enough
gas through to start and idle the engine,
but not enough for full throttle operation.
As the throttle is increased, allowing more
air to enter the intake, the engine will quit
from fuel starvation. Call your dealer or
the factory for instructions on where to
have the service valve replaced.
Meanwhile, to get by, you can continue to
open the service valve until you don't hear
a “click" and then the engine will run
normally. IF IT DOES NOT, call our
customer service department for further
assistance.
Excessive noise from under
burnisher
Belt has stretched or is loose
As a new belt wears in, it naturally
stretches a bit and the tensioner will begin
to rattle. Place the burnisher on its side
(with the muffler down) and reset by
taking up the slack in the belt and tighten
the Tensioner.
Starter barely turns the
engine over or the solenoid
just clicks on 12 volt models
The battery is low in charge
Recharge the battery using a 12 volt
battery charger at 4.12 amperes. The
battery is located under the frame at the
rear of the burnisher. The positive post
has the RED cable attached to it. Follow
the instructions that came with the battery
charger.
NOTE: this will continue to
happen unless the burnisher's engine
is run for sufficient time between starts
to recharge the battery.
Engine suddenly begins to
backfire regularly
Cracked spark plug boot
Remove the sparkplug lead from the
sparkplug and replace the boot. The
engine should now run smoothly. IF IT
DOES NOT, contact our customer service
department for further assistance.
