CUTTING METAL

1. Lift the swing arm fully upward as far
as it will go.
2. Adjust the mitre gauge as required.
3. Firmly lock the metal workpiece to be
cut in the vise.
4. Make sure you are wearing your safety
goggles, dust mask and hearing
protection.
5. Lower the cut-off blade until it
is about 1" (2.5 cm) above the
workpiece.
6. While holding the chop saw handle
firmly in your right hand, turn the
motor switch On.
7. Wait for motor to get up to its full
speed. Carefully lower the cut-off
blade until it contacts the workpiece.
8. Apply only slight pressure to the chop
saw handle as it begins to cut through
the workpiece. DO NOT apply too
much pressure to the handle, as this
will cause the motor to slow down,
slow the cutting action and damage
the motor.
NOTE:
The cut-off disc MUST NOT be touching
the workpiece when the motor switch is turned On.
NOTE:
Many sparks will be generated as soon as
the cut-off disc touches the workpiece.
WARNING!
Never touch the workpiece immediately
after a cut is completed. The metal in the
cutting area will be red hot and will cause
severe burns to your skin.

cut through the workpiece, release
the trigger switch immediately. Wait
for the motor to come to a complete
stop before lifting the cut-off disc
away from the workpiece.
REPLACING CARBON MOTOR
BRUSHES
The carbon motor brushes will wear
down and require replacing. The time
intervals between replacements will vary
depending upon the type of materials
being cut and the hours of use. It is
recommended that the brushes be
checked after each 10 hours of use. When
the length of the carbon brush reaches
1/4" (6.35 mm), the brushes should be
replaced.
1. Use a #2 screwdriver and remove
four screws (1) from the motor end
cap (2).
2. Pull the motor end cap from the
motor housing (3).
3. Use needle-nose pliers to pull the
spade connector (4) from the spade.
4. Use needle-nose pliers to pull the
brush retainer spring (5) away from
the carbon brush (6).
WARNING!
Unplug the tool from the power source
before removing the motor end cap.
