Operation - Makita 3612 Instruction Manual

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 bolt height, turn the hex bolts with a
screwdriver or wrench. The stopper block is also
convenient for making three passes with progressively
deeper bit settings when cutting deep grooves.
Switch action
For tool without lock-off button
Fig.5
CAUTION:
Before plugging in the tool, always check to see
•
that the tool is switched off.
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.
For tool with lock-off button
Fig.6
CAUTION:
Before plugging in the tool, always check to see
•
that the switch trigger actuates properly and returns
to the "OFF" position when released.
Make sure that the shaft lock is released before the
•
switch is turned on.
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, push in the lock-off button and pull the
switch trigger. Release the switch trigger to stop.
Speed adjusting dial
For model 3612C only
Fig.7
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.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and
•
unplugged before carrying out any work on the tool.
Installing or removing the bit
Fig.8
CAUTION:
Install the bit securely. Always use only the wrench
•
provided with the tool. A loose or overtightened bit
can be dangerous.
Use always a collet which is suitable for the shank
•
diameter of the bit.
Do not tighten the collet nut without inserting a bit or
•
install small shank bits without using a collet sleeve.
Either can lead to breakage of the collet cone.
Use only router bits of which the maximum speed,
•
as indicated on the bit, does exceed the maximum
speed of the router.
Insert the bit all the way into the collet cone. Press the
shaft lock to keep the shaft stationary and use the wrench
to tighten the collet nut securely. When using router bits
with smaller shank diameter, first insert the appropriate
collet sleeve into the collet cone, then install the bit as
described above.
To remove the bit, follow the installation procedure in
reverse.

OPERATION

Fig.9
CAUTION:
Before operation, always make sure that the tool
•
body automatically rises to the upper limit and the
bit does not protrude from the tool base when the
lock lever is loosened.
Before operation, always make sure that the chip
•
deflector is installed properly.
Set the tool base on the workpiece to be cut without the
bit making any contact. Then turn the tool on and wait
until the bit attains full speed. Lower the tool body and
move the tool forward over the workpiece surface,
keeping the tool base flush and advancing smoothly until
the cutting is complete.
When doing edge cutting, the workpiece surface should
be on the left side of the bit in the feed direction.
