sure your extension cord is in good condition. Replace or repair damaged or worn cord
immediately. When using an extension cord, be sure to use one heavy enough to carry the
current your product will draw. An undersized cord will cause a drop in line voltage resulting
in loss of power and overheating. Table 1 shows the correct size to use depending on cord
length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the
gage number, the heavier the cord.

GROUNDING INSTRUCTIONS
This tool should be grounded while in use to protect the operator from electric shock. The
tool is equipped with a three-conductor cord and three-prong grounding type plug to fit the
proper grounding type receptacle. The green (or green and yellow) conductor in the cord is
the grounding wire. Never connect the green (or green and yellow) wire to a live terminal.
Your unit is for use on 120 volts and has a plug that looks like Fig. “A”.

An adapter Fig. “B” and “C” is available for connecting Fig. “A” type plugs to two-prong
receptacles. The green-colored rigid ear, lug, etc., extending from the adapter must be connected to a permanent ground, such as a properly grounded outlet box.

optimum performance and safety of operation.
10. Causes and Operator Prevention of Kickback:
Kickback is a sudden reaction to a pinched,
bound, or misaligned wheel, causing an
uncontrolled tool to lift up and out of the workpiece toward the operator.
When the wheel is pinched or bound tightly
by the kerf closing down, the wheel stalls and
the motor reaction drives the unit rapidly back
toward the operator.
If the wheel becomes twisted or misaligned in
the cut, the teeth at the back edge of the
wheel can dig into the top surface of the
material being cut causing the wheel to climb
out of the kerf and jump back toward the
operator.
Kickback is the result of tool misuse and/or
incorrect operating procedures or conditions
and can be avoided by taking proper precautions as given below:
Maintain a firm grip on the tool and position your body and arm to allow you to
resist KICKBACK forces.
can be controlled by the operator, if proper
precautions are taken.
When wheel is binding, or when interrupting a cut for any reason, release the trigger and hold the tool motionless in the
material until the wheel comes to a complete stop. Never attempt to remove the
tool from the work or pull the tool backward while the wheel is in motion or KICK-

Supports must be placed under the panel on
both sides, near the line of cut and near the
edge of the panel.

11. When operating the tool, keep the cord
away from the cutting area and position it
so that it will not be caught on the workpiece during the cutting operation. Operate with proper hand support, proper
workpiece support, and supply cord routing away from the work area.
WARNING: It is important to support the
workpiece properly and to hold the tool
firmly to prevent loss of control which
could cause personal injury.
