For the correct planer blade setting

Your planing surface will end up rough and uneven, unless the blade is set properly and securely. The blade

must be mounted so that the cutting edge is absolutely level, that is, parallel to the surface of the rear base.

Below are some examples of proper and improper settings.

(A) Front base (Movable shoe)

(B) Rear base (Stationary shoe)

Adjusting the depth of cut (Fig. 12)

Depth of cut may be adjusted by simply turning the

knob on the front of the tool.

CAUTION:

Before plugging in the tool, always check to see that

the switch trigger actuates properly and returns to the

''OFF'' position when released.

For tool without lock button and lock-off button

(Fig. 13)

To start the tool, simply pull the trigger. Release the

trigger to stop.

For tool with lock button (Fig. 14)

To start the tool, simply pull the trigger. Release the

trigger to stop. For continuous operation, pull the

trigger and then push in the lock button. To stop the

tool from the locked position, pull the trigger fully, then

release it.

For tool with lock-off button (Fig. 15)

To prevent the trigger from being accidentally pulled,

a lock-off button is provided. To start the tool, press

the lock-off button and pull the trigger. Release the

trigger to stop.

Planing operation (Fig. 16)

First, rest the tool front base flat upon the workpiece

surface without the blades making any contact.

Switch on and wait until the blades attain full speed.

Then move the tool gently forward. Apply pressure on

the front of tool at the start of planing, and at the back

at the end of planing. Planing will be easier if you

incline the workpiece in stationary fashion, so that you

can plane somewhat downhill.

The speed and depth of cut determine the kind of

finish. The power planer keeps cutting at a speed that

will not result in jamming by chips. For rough cutting,

the depth of cut can be increased, while for a good

finish you should reduce the depth of cut and advance

the tool more slowly.

Shiplapping (Fig. 17, 18, 19 & 20)

To make a stepped cut as shown in Fig. 17, use the

edge fence.

Draw a cutting line on the workpiece. Insert the edge

fence into the hole in the front of the tool. Align the

blade edge with the cutting line.

Adjust the edge fence until it comes in contact with the

side of the workpiece, then secure it by tightening the

screw.

You may wish to add to the length of the fence by

attaching an extra piece of wood. Convenient holes

are provided in the fence for this purpose, and also for

attaching an extension guide (optional accessory).
