Sequence after Starting Engine

Cutting Asphalt, Tar and Reinforced Materials

Wheel Thrust
Move ignition switch down to "STOP" position. Keep wheel in the clear until
all movement stops.
If engine does not stop, pull choke control knob out fully to stop engine. The
choked engine will slow to a stop. Be sure to keep the wheel in the clear until
all movement stops.
With trigger latched, wheel will rotate as soon as engine starts. Keep
wheel in the clear.
Wheel will rotate for some time after the trigger is released. Keep
wheel in the clear until all movement stops.
When engine is warm from previous running, move ignition switch to
"RUN" position. And push choke control knob all the way in. Try cranking
at idle throttle without latching it. If this does not work, try again with throttle
latched. Choking may be needed if the engine has cooled. But, to avoid
the possibility of over-choking and fl ooding, always fi rst try to start a warm
engine without choking it.
1. Squeeze and release trigger to unlatch it and take control of the throttle.
2. Let engine warm to operating temperature before doing any cutting.
3. Take cutting stance on left side of cutter. Never get any part of your body
behind the cutter. Hold the cutter fi rmly with both hands. Throttle up to
cutting speed and make gentle wheel contact with the work.
Old, cold and hardened asphalt paving can be cut with a masonry wheel with
good results and little trouble with tarring of the wheel. Fresh asphalt and
tarred surfaces can gum up the wheel and slow its cutting action. Some tar
or resin-impregnated materials also may present problems of this sort.
Masonry containing metal reinforcement is best cut with a masonry wheel
which can cut through the reinforcing steel better than a wheel designed for
metal can cut the masonry. Expect faster than normal wheel wear.
Do not raise cutter above chest height, because the cutter is hard
to control when held up high, and dust or sparks will fall on you.
Wear hearing protection. Without it you risk hearing loss,
especially where bounce-back of sound waves off nearby surfaces
increases the noise.
Do not take awkward or risky operating positions. Find solid
footing for both feet, and always hold the cutter fi rmly with both
hands. Never make one-handed cuts.
When the wheel engages the work, the thrust will exert a forward
pull which you must be ready to control. Keep bystanders out of
the way.
