CAUTION:
•Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.

Place the tool on a flat surface. Loosen the screw securing the stopper pole.
Loosen the lock lever and lower the tool body until the bit just touches the flat surface. Tighten the lock lever to lock the tool body.

Next, lower the stopper pole until it makes contact with the adjusting hex bolt. Align the depth pointer with the "0" graduation.
Raise the stopper pole until the desired depth of cut is obtained. The depth of cut is indicated on the scale (1
mmper graduation) by the depth pointer. Then tighten the screw to secure the stopper pole.
Now, your predetermined depth of cut can be obtained by loosening the lock lever and then lowering the tool body until the stopper pole makes contact with the adjusting hex bolt.

CAUTION:
•Since excessive cutting may cause overload of the motor or difficulty in controlling the tool, the depth of cut should not be more than 15 mm at a pass when cutting grooves with an 8 mm diameter bit.
•When cutting grooves with a 20 mm diameter bit, the depth of cut should not be more than 5 mm at a pass.
When you wish to cut grooves more than 15 mm deep with an 8 mm diameter bit or more than 5 mm deep with a 20 mm diameter bit, make several passes with progressively deeper bit settings.

The stopper block has three adjusting hex bolts which raise or lower 0.8 mm per turn. You can easily obtain three different depths of cut using these adjusting hex bolts without readjusting the stopper pole.
Adjust the lowest hex bolt to obtain the deepest depth of cut, following the method of "Adjusting depth of cut". Adjust the two remaining hex bolts to obtain shallower depths of cut. The differences in height of these hex bolts are equal to the differences in depths of cut.
To adjust the hex bolts, turn the hex bolts. The stopper block is also convenient for making three passes with progressively deeper bit settings when cutting deep grooves.
CAUTION:
When using a bit having total length of 60 mm or more, or edge length of 35 mm or more, the depth of cut cannot be adjusted as previously mentioned. To adjust, proceed as follows:
Loosen the lock lever and carefully adjust bit protrusion below the tool base to the desired depth of cut by moving the tool body up or down. Then retighten the lock lever to lock the tool body at that depth of cut. Keep the tool body locked at this position during use. Since the bit always protrudes from the tool base, be careful when handling the tool.
