GUIDELINES FOR EXTENSION CORDS
Use a proper extension cord. Make sure extension cords are in good condition.
When using an extension cord, be sure to use a cord heavy enough to carry the
drawn needed by the compound mitre saw. An undersized cord will cause a drop in
line voltage, resulting in loss of power and cause overheating. The table below shows
the correct size to use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the gauge number, the heavier the
cord.
Be sure extension cords are properly wired and in good condition. Always replace
a damaged extension cord or have it repaired by a qualified person before using it.
Protect extension cords from sharp objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for power tools. This circuit must not be less than
#6 wire and should be protected with a time-delay fuse. Before connecting the tool to
the power line, make sure the switch is in the OFF position and the electric current is
rated the same as the current stamped on the motor nameplate, running at a lower
voltage will damage the motor.

WARNING: Ensure the power supply outlet in question is properly grounded. If
you are not sure, have a licensed electrician check the outlet.
SPECIFIC SAFETY RULES
Use only crosscutting saw blades. When using the mitre saw to cut nonferrous
metal, make sure that the blade has a negative hook angle.
IMPORTANT: Do not use thin kerf blades. Thin kerf blades can deflect and contact
the guard which can cause possible injury to the operator.
Do not operate the mitre saw until it is completely assembled and installed according
to these instructions.
If you are not thoroughly familiar with the operation of mitre saws, seek guidance
from a supervisor, instructor, or other qualified person.
Always hold the work firmly against the fence and table. DO NOT perform any
operation free-hand (use a clamp or vise wherever possible).
Keep hands out of the path of the saw blade. If the work piece causes your hands to
be within the "no hands" zone (3'' from blade), the work piece should be clamped in
place before making the cut.
Be sure the blade is sharp, runs freely, and is free of vibration.
Allow the motor to come up to full speed before starting a cut.
Keep the motor air slots clean and free of chips or dust.
