CSG-680
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 saw. Never get any part of your body
behind the saw. Hold the saw firmly with both hands. Throttle up to cutting
speed and make gentle wheel contact with the work.
Stopping Engine
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.
WARNING
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.
Restarting Warm Engine
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 flooding, always first try to start a warm engine without
choking it.
Sequence after Starting Engine
Cutting Asphalt, Tar and Reinforced Materials
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.
DANGER
z
Do not raise saw above chest height, because the saw is hard to
control when held up high, and dust or sparks will fall on you.
z
Wear hearing protection. Without it you risk hearing loss,
especially where bounce-back of sound waves off nearby surfaces
increases the noise.
z
Do not take awkward or risky operating positions. Find solid
footing for both feet, and always hold the saw firmly with both
hands. Never make one-handed cuts.
z
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.
