Two minute rule
The machine may be tipped backward or on its side to facilitate access for cleaning or
service, but no longer than 2 minutes. If the machine is held in this position for too long,
the engine can be damaged by gasoline draining into the crankcase. Should this happen,
perform an extra oil change on the engine over a few revolutions with the starter handle
before starting the engine again.
Cleaning and washing
Regular cleaning and washing will increase the machine’s life span. Make it a habit to clean
the machine directly after use, before the dirt sticks. Check before reusing that the fuel tank
lid is properly in place to avoid getting water in the tank. Use caution when using high-
pressure spray because warning decals, instruction signs and the engine can be damaged.
Do not exceed 70 bar/1000 PSI water pressure when cleaning.
Lubricate the machine after cleaning. This is particularly important if the machine is to be
stored.
Lubricating Bearings
Cutting blade bearings should be greased after every 10 hours of operation. Lubricate two
fittings (one on each cutting blade bearing).
Drive belts
The drive system of the stump machine is composed of a 9J Joined Narrow V-belt. The stump
machine’s V-belt tension should be checked daily.
Before beginning to check or adjust belt: shutdown the machine, be sure that all
moving parts have come to a complete stop. Extreme caution must be used to
avoid death or serious injury. Stay clear of belts, pulley, clutch and cutting blade
when they are moving.
To adjust belt tension, loosen the 2 bolts behind clutch. Also loosen the 4 engine mounting
bolts. Turn square head adjusting bolt on frame clockwise to tighten belt, counter clockwise
to loosen belt. (Make sure to tighten all bolts after proper belt adjustment is
achieved). To check belt tension, you should be able to depress the belt down about 1/4-
3/8〞(6 -10 mm) from the original position.
To extend belt life, proper tension must be maintained. A loose belt will cause
excessive cutting blade slippage and belt failure. A belt that is too tight can cause
bearing, shaft and belt failure.
NOTICE
PUMP GREASE IN SLOWLY AND CAREFULLY TO PREVENT DAMAGE TO THE BEARING
SEALS. USE EXTREME CAUTION WHEN USING A HIGH PRESSURE OR HIGH VOLUME
GREASE GUN.
