Safety Precautions
A. Saw blade should be inspected daily for excessive wear,
core cracks and arbor damage. Replace any blade that
shows signs of damage.
B. To mount the blade, clean the arbor and outer flanges,
and tighten the nut securely.
C. DO NOT place any portion of your body in line with the
blade while it is rotating.
D. Wet cutting blades MUST be used with water.
E. To reduce the risk of electrical shock, we recommend
the use of GFCI and to refer servicing to a qualified pro-
fessional.
F. When operating the saw, be sure to wear proper safety
gear, such as safety glasses, dust mask, and hearing
protection. A hard hat is also recommended.
G. Never use the machine improperly or work in an unsafe
manner.
H. Maintain alertness while operating the machine. Failure
to maintain attention, by the operator, may lead to seri-
ous injury.
I. Keep work area clean.
J. Before you start working, familiarize yourself with the
work site and its surroundings. Take notice of circum-
stances which may impede work or traffic, observe soil
conditions (good bearing or not) and take measures to
ensure safety (e.g. the shielding of roadworks from pub-
lic traffic).
K. Take measures to ensure that the machine is in a safe
and trouble-free condition prior to usage. Use the ma-
chine only when all protective devices (i.e. guards, noise
absorbers, emergency-off devices) are in place and in
working order.
L. A visual check of the machine must be made at least
once a shift to ensure that visible damages or faults
are recognized. Any changes (including changes in
the performance or behavior of the machine) must be
reported to the supervisor. If necessary, stop the ma-
chine at once and secure it.
M. In the case of a malfunction, stop the machine imme-
diately and secure it. Fix the problem as soon as pos-
sible.
N. To stop and start the machine follow the operating in-
structions and observe any indicator lights.
O. Keep out of reach of children. Before operating ma-
chine, be sure the activated machine will be of no dan-
ger to anyone.
P. Be sure to connect the plug to a properly grounded re-
ceptacle to reduce the risk of electric shock.
Q. Wear proper apparel. Do not wear loose clothing or ac-
cessories. Keep hair and body parts away from open-
ings and moving parts.
