CUTTING INSTRUCTION

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.
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 saw above chest height, because the saw 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 saw firmly with both
hands. Never make one-handed cuts.
Kickback may force the cutting-off wheel up and back toward the
operator with a lightning-fast reaction. Kickback can occur whenever
the upper-half of the cutting-off wheel touches an object while op-
erating the machine. This may cause the cutting wheel to touch the
operator, resulting in serious injury
 Rotational kickback
Cutting with the upper part of the cutting wheel generates kickback
from the material being cut; this causes the tip of the cutting wheel
to kick back from the rotation and is extremely dangerous. Always
cut with the bottom of the cutting wheel.
 Linear kickback
When cutting with the bottom of the cutting wheel, the machine may
generate a force that pulls the machine forward. Always hold the
handle firmly while working.
