grooves more than 20 mm (13/16") deep, make

several passes with progressively deeper bit

settings.

• Do not lower the knob too low. The bit will protrude

dangerously.

Stopper block

003657

The stopper block has three adjusting hex bolts which

raise or lower 0.8 mm (1/32") 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, first loosen the hex nuts on the

hex bolts with the wrench and then turn the hex bolts.

After obtaining the desired position, tighten the hex nuts

while holding the hex bolts in that desired position. The

stopper block is also convenient for making three passes

with progressively deeper bit settings when cutting deep

grooves.

Switch action

003660

CAUTION:

• Before plugging in the tool, always check to see

that the tool is switched off.

• Switch can be locked in "ON" position for ease of

operator comfort during extended use. Apply

caution when locking tool in "ON" position and

maintain firm grasp on tool.

• Make sure that the shaft lock is released before the

switch is turned on.

• Hold the tool firmly when turning off the tool, to

overcome the reaction.

To start the tool, move the switch lever to the I (ON)

position. To stop the tool, move the switch lever to the O

(OFF) position.

Electric brake

This tool is equipped with an electric brake. If the tool

consistently fails to quickly stop after switch lever moving

to the O (OFF) position, have tool serviced at a Makita

service center.

Speed adjusting dial

For model 3612C only

003802

The tool speed can be changed by turning the speed

adjusting dial to a given number setting from 1 to 5.

Higher speed is obtained when the dial is turned in the

direction of number 5. And lower speed is obtained when

it is turned in the direction of number 1.

This allows the ideal speed to be selected for optimum

material processing, i.e. the speed can be correctly

adjusted to suit the material and bit diameter.

Refer to the table for the relationship between the

number settings on the dial and the approximate tool

speed.

CAUTION:

• If the tool is operated continuously at low speeds

for a long time, the motor will get overloaded,

resulting in tool malfunction.

• The speed adjusting dial can be turned only as far

as 5 and back to 1. Do not force it past 5 or 1, or the

speed adjusting function may no longer work.
