Operation - Makita 3612 Instruction Manual

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.
Fig.10
NOTE:
Moving the tool forward too fast may cause a poor
•
quality of cut, or damage to the bit or motor.
Moving the tool forward too slowly may burn and
mar the cut. The proper feed rate will depend on
the bit size, the kind of workpiece and depth of cut.
Before beginning the cut on the actual workpiece, it
is advisable to make a sample cut on a piece of
scrap lumber. This will show exactly how the cut
will look as well as enable you to check
dimensions.
When using the straight guide or the trimmer guide,
•
be sure to install it on the right side in the feed
direction. This will help to keep it flush with the side
of the workpiece.

Straight guide (optional accessory)
Fig.12
The straight guide is effectively used for straight cuts
when chamfering or grooving.
Install the straight guide on the guide holder with the
wing bolt (B). Insert the guide holder into the holes in the
tool base and tighten the wing bolt (A). To adjust the
distance between the bit and the straight guide, loosen
the wing bolt (B) and turn the fine adjusting screw (1.5
mm per turn). At the desired distance, tighten the wing
bolt (B) to secure the straight guide in place.
Fig.13
Wider straight guide of desired dimensions may be
made by using the convenient holes in the guide to bolt
on extra pieces of wood.
Fig.14
When using a large diameter bit, attach pieces of wood
to the straight guide which have a thickness of more
than 15 mm to prevent the bit from striking the straight
guide.
When cutting, move the tool with the straight guide flush
with the side of the workpiece.
Templet guide (optional accessory)
Fig.15
The templet guide provides a sleeve through which the
bit passes, allowing use of the tool with templet patterns.
For tool without lock plate
To install the templet guide, loosen the screws on the
tool base, insert the templet guide and then tighten the
screws.
Fig.16
For tool with lock plate
To install the templet guide, pull the lock plate lever and
insert the templet guide.
