WARNING: To avoid electrical hazards, fire hazards or damage to the cutting tool,
use proper circuit protection.
This tool is wired at the factory for 110–120 V operation. It must be connected to a 110–120 V,
15 A time delayed fuse or circuit breaker. To avoid shock or fire, replace power cord
immediately if it is worn, cut or damaged in any way.

GENERAL SAFETY RULES
WARNING: Read and understand all instructions. Failure to follow all instructions
listed below may result in electric shock, fire and/or serious personal injury.
Work area
• Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
• Do not operate power tools in potentially explosive environments, such as in the
presence of flammable liquids, gas or dust. Power tools create sparks which may ignite
the dust or fumes.
• Keep bystanders, children and visitors away while operating the tool. Distractions can
cause you to lose control.
ELECTRICAL SAFETY
• Double insulated tools are equipped with a polarized plug (one blade is wider than the
other). This plug will fit in a polarized plug only one way. If the plug does not fit fully in
the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to
install a polarized outlet. Do not alter the plug in any way. Double insulation eliminates
the need for the three-prong grounded power cord and grounded power supply system.
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is increased risk of electric shock if your body is grounded.
• Do not expose power tools to rain or wet conditions. Water entering the power tool will
increase the risk of electric shock.

4. Screw the internally-threaded circle cutting guide mounting disc (7) onto the externally-
threaded circle cutting guide mounting insert and hand tighten.
NOTES:
a) Make sure the boss (8) on the cutting guide mounting disc goes through the hole in
the circle guide.
b) Do not over tighten the circle cutting guide mounting plastic parts. Hand tighten only.
5. Adjust the circle cutting guide radius by loosening pivot point knob (9), sliding it to the
correct circle radius and re-tightening in the desired location.
NOTE: Check circle cutting guide radius setting by measuring from the pivot point to the
outside of the cutting bit.

WARNING: Unplug the tool from the power source before changing accessories,
changing bits and making adjustments.
Before turning the tool ON, check to make sure bit and all accessory fasteners are
securely tightened.
1. Mark the centre of the circle you wish to cut on the workpiece and drill a 6 mm or 1/4” pilot
hole.
2. Adjust cutting bit depth to 1/8” longer than the thickness of the material being cut (Ill. 7).
3. Adjust the circle cutting guide radius by loosening pivot point knob, sliding it to the correct
circle radius and re-tightening in the desired location.
NOTE: Check circle cutting guide radius setting by measuring from the pivot point to the
outside of the spiral bit.
4. Rest the edge of the freehand cutting guide on the workpiece with the bit at an angle of
about 45° (Ill. 13). Insert the circle cutting guide pivot point into the pilot hole drilled at the
centre of the circle.
NOTE: DO NOT let the bit touch the workpiece before switch is turned ON and the tool is
up to full speed.
5. Turn the switch ON.
6. When the motor is up to full speed, slowly tip the tool and circle cutting guide assembly to
an upright position, letting the bit cut into the workpiece. Be careful to keep the pivot point
located at the centre of the circle to be cut. Once the tool has reached the upright position
and the bit has cut through the workpiece, slowly move the tool in a clockwise direction
using slow steady pressure to make the cut. Continue to cut the circle, keeping the tool
upright and rotating around the circle cutting guide pivot point.
7. When cut is complete, turn the tool OFF, wait until it comes to a complete stop and remove
it from the workpiece.
