Adjusting the depth of cut

CAUTION.

 Always ensure that the tool is switched off 

and unplugged from the power supply before making 

adjustments or installing or removing blades.
Rotate the depth adjustment knob (3) clockwise for a 

deeper cut and anti-clockwise for a shallower cut.
The numbers on the ring under the depth adjustment 

knob indicate the depth of cut. 

Example, when “1” is next to the 

pointer on the front of the planer, 

the depth of cut is approximately 

1mm. If it is necessary to 

accurately determine the depth 

of cut, plane a scrap piece of 

wood, measure the difference in 

thickness and adjust the setting  

if necessary.

Switching on and off

CAUTION.

 Before plugging the 

machine into the power socket 

always check that the on/off 

switch (1) and lock-off button (2) 

work properly.
1. Plug in the machine and grip 

the tool with your thumb on the 

on/off switch (1). 

2. Push lock-off button (2) forward 

and press in the on/off switch 

(1) with the thumb of the hand 

gripping the tool.  You can 

release the finger hold on the 

lock off button (2) once the 

planer has started.

3. To stop the tool, release the 

thumb hold on the on/off button (1). 

4. In order to restart the machine, it is necessary to operate 

both the lock-off button (2) and the on/off switch (1).  

This is an important safety feature that helps prevent 

accidental operation of the planer. Only when you release 

the thumb hold on the on/off button (1) will the planer stop.

Planing

1. Rest the front base (9) flat on 

the workpiece surface without 

the blades making any contact 

with the workpiece.

2. Switch on the tool and wait for 

the blades to reach full speed. 

3. Move the tool gently forward, 

applying pressure on the front 

of the tool, using your hand on 

the secondary handle (14) at  

the start of planing and 

pressure at the rear of the tool, 

using your hand on the main 

handle (4) towards the end of 

the planing stroke.

4. Push the planer beyond the 

edge of the workpiece without tilting it downwards.

NOTE.

 Planing is easier if you incline the workpiece slightly 

away from you so that you plane “downhill”.
5. The rate of planing and the depth of cut determine the 

quality of the finish. For rough cutting, you can increase 

the depth of cut, however to achieve a good finish you 

will need to reduce the depth of cut and advance the tool 

more slowly.

CAUTION.

 Moving the machine too fast may cause a poor 

quality of cut and can damage the blades or the motor.
Moving the machine too slowly may burn or mar the cut. 

The proper feed rate will depend on the type of material 

being cut and the depth of the cut. Practice first on a scrap 

piece of material to gauge the correct feed rate and the  

cut dimensions.

CAUTION.

 Always use two hands to hold the planer. 

CAUTION.

 Where possible, clamp the workpiece to  

the bench.
