OPERATION

DISCONNECT THE TOOL FROM THE POWER SOURCE.

Always wear safety glasses while operating a laminate trimmer.

1.Allow your workpiece to overhang the base material by at least 1/8".

2.Firmly grasp the motor housing, being sure switch is in the “OFF” position.

3.Ensure that the bit is clear of foreign objects and that the cord will not “hang up” on any obstructions.

4.Hold the workpiece firmly in place. Use clamps when necessary.

5.Plug in the power supply cord. Be alert to resist the starting torque of the motor. Turn motor “ON”.

6.Allow the motor to reach “full speed”. Place the base of the trimmer on the surface of the workpiece. Feed the trimmer into the work until the bit pilot contacts the base material. When guiding on a previously laminated surface, always wax or lubricate the area where the guide will ride.

NOTE: While operating the trimmer with the tilt base at any tilt setting other than “0” degrees, keep the long side of the base perpendicular to the piloting surface to prevent possible work spoilage.

7.Feed from left to right with a smooth steady motion (See Fig. 16).

8.When the operation is complete, turn the switch “OFF”. Allow the motor to come to a complete stop before laying the trimmer down.
