Brake Adjustment

For fine adjustment, loosen set screw on side of brake lever knob. Adjust clockwise to tighten brake; adjust
counter clockwise to loosen brake. (Wheel should lock completely, tighten set screw).

For coarse adjustment, turn adjusting nuts on brake cable fitting at brake cable mount.

Two-Minute Rule

The machine may be tipped backward or on its side to facilitate access for cleaning or service, but

longer

than

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.

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

Lubricate the cutting wheel bearings BEFORE first use.
Re-lubricate the cutting wheel bearings after every 10
hours of use.

Failure to properly lubricate and maintain

the cutting wheel bearings may void product warranty

Use a suitable grease gun (not supplied) and automotive
wheel bearing grease (not supplied). Attach the grease gun
to the grease nipple on the bearing holder (

) and pump in 1

or 2 squeezes of grease. Always grease both bearings on
either side of the cutting wheel.

NOTE:

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.

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 wheel 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

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
wheel slippage and belt failure. A belt that is too tight can cause bearing, shaft and belt failure.
