MITER SAW SAFETY
WARNING
40. Do not pick up or carry this saw by the
lower blade guard. Doing so could cause damage
to the guard.
WARNING
41. Do not use this saw to cut fiber
cement board. This saw is not intended to cut fiber
cement board.
42. Remove hold-down clamp from saw before folding
and transporting.
WARNING
43. Do not transport the unit standing up
in a vehicle.
44. Make sure power cord is wrapped up securely before
folding the saw for storage or transport.

ELECTRICAL REQUIREMENTS AND SAFETY

POWER SUPPLY AND MOTOR SPECIFICATIONS

The AC motor used in this saw is a universal, nonreversible
type. See "MOTOR" in the "PRODUCT SPECIFICATIONS"
section on page 1.
WARNING
To avoid electrical hazards, fire hazards, or
damage to the tool, use proper circuit protection. Your
saw is wired at the factory for 120 V operation. Connect
to a 120 V, 15 A circuit and use a 15 A time delay fuse
or circuit breaker. To avoid shock or fire, if power cord
is worn or cut, or damaged in any way, have it replaced
immediately.
ELECTRICAL REQUIREMENTS
Replacement parts – When servicing use only identical
replacement parts.
Polarized plugs – This saw has a plug that looks like the one
shown below:
To reduce the risk of electrical shock, this saw has a polarized
plug (one blade is wider than the other). This plug will fit in a
polarized outlet only one way. If the plug does not fit fully in
the outlet, reverse the plug. If it still does not fit, contact a
qualified electrician to install the proper outlet. Do not change
the plug in any way.
WARNING
Double insulation does not take the place
of normal safety precautions when operating this tool.
To avoid electrocution:
1. Use only identical replacement parts when servicing a tool
with double insulation. Servicing should be performed by
a qualified technician.
2. Do not use power tools in wet or damp locations or
expose them to rain or snow.
MOTOR SAFETY PROTECTION
IMPORTANT:
To avoid motor damage, the motor should be blown out or
vacuumed frequently to keep sawdust from interfering with
the motor ventilation.
1. CONNECT this saw to a 120 V, 15 A circuit with a 15 A
time-delay fuse or circuit breaker. Using the wrong size
fuse can damage the motor.
2. If the motor won't start, release the trigger switch
immediately. UNPLUG THE SAW. Check the saw blade
to make sure it turns freely. If the blade is free, try to
start the saw again. If the motor still does not start, refer
to the TROUBLESHOOTING GUIDE.
3. If the tool suddenly stalls while cutting wood, release the
trigger switch, unplug the tool, and free the blade from
the wood. The saw may now be started and the cut
finished.
4. FUSES may "blow" or circuit breakers may trip
frequently if:
a. MOTOR is overloaded – overloading can occur if you
feed too rapidly or make too many start/stops in a
short time.
b. LINE VOLTAGE is more than 10% above or below the
nameplate voltage rating. For heavy loads, the voltage
at motor terminals must equal the voltage specified
on the nameplate.
c. IMPROPER or dull saw blades are used.
5. Most motor troubles may be traced to loose or incorrect
connections, overload, low voltage or inadequate power
supply wiring. Always check the connections, the load
and supply circuit if the motor doesn't run well. Check
minimum gauge for the length of cord you are using on
the chart below.
