ADjUSTING DEPTH OF CUT

Proper cutting depth should be determined according to the hardness, gumminess or moisture content of the material being cut, as well as the feed rate, and is largely a matter of experience. Start with a light cut and increase the depth setting if the planer moves freely through the workpiece with no excessive load on the motor. Do not change depth of cut while planing.

The cutting depth is determined by the difference in height between the adjustable front shoe, and the fixed rear shoe of the planer. As the front shoe is adjusted, it retracts and exposes the blade, which can then

remove the desired amount from the workpiece. The cutting depth is graduated from 0 to 1/16 of an inch, and the "0" indicates the blade is fully retracted.

Adjusting depth of cut: Rotate depth adjustment knob until the indicator engages the detent which indicates the desired cutting depth on the depth scale (Fig. 1).

The planer may be set to cut any depth from 0 to 1/16 of an inch.

PORT SELECTOR LEVER

Moving the port selector lever to position 1 (towards front of tool) discharges chips to the left, while position 2 (towards rear of tool) discharges chips to the right (Fig. 1)

Operating Instructions

TRIGGER "ON/OFF" SWITCH Hold the tool with both hands while starting the

tool, since torque from the motor can cause the tool to twist.

To turn tool "ON", depress the "Lock-OFF" button and squeeze the trigger switch. To turn the tool "OFF", release the trigger switch which is spring loaded and will return to "OFF" position automatically.

To increase switch life, do not turn switch on and off while tool and drum are held against a workpiece.

BRAKE

When the trigger is released it activates the electrical brake to stop the blade quickly. This feature is especially useful when making repetitive cuts.

PLANING ACTION

Check that the workpiece is held in place securely on your work surface. Stand comfortably, hold the planer firmly with both hands. With the planer fully adjusted, place the front shoe on the workpiece, (be certain that the cutter drum is not in contact with the work) and start the planer. With pressure on the front shoe, and the fence against the side of the work (to control the width or angle) feed the planer steadily until the rear shoe fully engages the workpiece. Gradually transfer pressure to the rear shoe and continue planing to the end of the cut. Feed the planer at a uniform and reasonable rate, which does not put excessive strain on the motor or blades.

Do not pull the planer back over the surface already cut. Use progressive cuts until you are

near the desired depth, and then re-adjust to a light cut for the final pass to obtain a good surface finish.

!CAUTION The motor may stall if improperly used or

overloaded. Reduce the pressure (feed rate) or depth of cut to prevent possible damage to the tool if the motor labors.

STANDARD GUIDE FENCE

The guide fence can be used to control the width of the cut or for simply providing added stability and protection when cutting materials that are up to 3-1/4" wide.

Note: When used for rabbeting, the fence must be attached to the left side of the tool. (Fig. 1).

Installing the guide fence: Place the wing knob through the appropriate hole in the guide bracket and screw into preferred side of the housing. Securely tighten wing knob. Setting the cutting width: Place wing knob through the appropriate fence arm and slide along the guide bracket to the desired position. Securely tighten wing knob. Be certain that the flat washer (supplied) is fitted between the bottom of the guide fence and wing knob or the guide fence is likely to slip.

DELUxE GUIDE FENCE

The deluxe guide fence can be used to control the width of the cut or for simply providing added stability and protection when cutting materials that are up to 3-1/4" wide, with the additional capability of guiding the planer on any angle up to 45 degrees, to allow edge chamfering and beveling (Fig. 7).
