MasterCraft 55-6857-6 Operating Manual page 5

Replacement parts: When servicing, use only identical replacement parts.
Polarized plugs: This mitre saw has a plug that looks like the one shown:
To reduce the risk of electrical shock, this mitre saw has a polarized plug (one blade
is wider than the other). This plug will fit in a polarized outlet only one way. If it still
does not fit, contact a licensed electrician to install a proper outlet. Do not change or
alter the plug in any way.
WARNING: Double insulation does not take the place of normal safety
precautions when operating this tool.
WARNING: To avoid electrocution:
1. Use only identical replacement parts when servicing a tool with double insulation.
Servicing should be performed by qualified service technicians.
2. Do not use power tools in wet or damp locations or expose them to rain or snow.
This tool is intended for indoor use only.
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.
CONNECT this mitre saw to a 120 V, 9 A. Circuit with a 9 A time-delay fuse or circuit
breaker. Using the wrong size fuse can damage the motor.
IF the motor won't start, release the ON/OFF 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.
"TROUBLESHOOTING GUIDE"
IF the tool suddenly stalls while cutting wood, release the ON/OFF trigger switch,
unplug the tool, and free the blade from the wood. Check to see that the mitre saw is
operating normally. If so, resume cutting operation. If not, refer to "TROUBLE
SHOOTING GUIDE"
FUSES may "blow" or circuit breakers may trip frequently if:
a. MOTOR is overloaded–overloading can occur if work piece is fed too rapidly or too
many "start/stops" are made 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.
Most motor troubles may be traced to loose or incorrect connections, overloading,
low voltage or inadequate power supply wiring. Always check the connections, the
load and the supply circuit if the motor does not run well. Refer to extension cord
chart in this manual.
If the motor still does not start, refer to the
