DOUBLE INSULATED
The power tool is double insulated to
provide a double thickness of insulation
between you and tool’s electrical
system. All exposed metal parts are
isolated from the internal metal motor
components with protecting insulation.
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 fi t in a polarized outlet only one
way. If the plug does not fi t fully in the
outlet, reverse the plug. If it still does
not fi t, contact a qualifi ed electrician to
install the proper outlet. Do not change
the plug in any way.
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 qualifi ed 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 circuit.
This circuit must not be less than a
#12 wire with a 20 A time lag fuse or
a #14 wire with a 15 A time lag fuse.
NOTE: When using an extension
cord on a circuit with a #14 wire, the
extension cord must not exceed 25
feet in length.
2. If the motor will not 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 fi nished.
4. FUSES may “blow” or circuit
breakers may trip frequently if:
a. MOTOR is overloaded –
overloading can occur if you feed
