INSPECTION, CLEANING AND REPLACING THE SPARK PLUG
1. Disconnect the spark plug wire and remove the spark plug, use a spark plug wrench.
2. Clean the spark plug and measure the distance between the spark gap (distance between
electrodes). The correct distance is between 0.7mm-0.8mm
0.7 mm - 0.8 mm
3. Replace the spark plug.
When replacing with a new one after tightening; tighten an additional 1/2 turn, tighten by
hand. When mounting the old spark plug, tighten an additional 1 / 8-1 / 4 turn.
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 checkb
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 cut-
ting blade slippage and belt failure. A belt that is too tight can cause bearing, shaft and belt
failure.
