Functional Description; Operation - Makita 3612BR Instruction Manual

12. Do not leave the tool running. Operate the tool
only when hand-held.
13. Always switch off and wait for the bit to come to a
complete stop before removing the tool from
workpiece.
14. Do not touch the bit immediately after operation; it
may be extremely hot and could burn your skin.
15. Do not smear the tool base carelessly with thinner,
gasoline, oil or the like. They may cause cracks in
the tool base.
16. Use bits of the correct shank diameter suitable for
the speed of the tool.
17. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
18. Always use the correct dust mask/respirator for
the material and application you are working with.

WARNING:
DO NOT let comfort or familiarity with product (gained
from repeated use) replace strict adherence to safety
rules for the subject product. MISUSE or failure to
follow the safety rules stated in this instruction
manual may cause serious personal injury.

FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Adjusting the depth of cut (Fig. 1)
Place the tool on a flat surface. Loosen the lock lever and
lower the tool body until the bit just touches the flat
surface. Press the lock lever down to lock the tool body.
Now lower the stopper pole until it makes contact with the
stopper block. The stopper pole can be moved rapidly by
depressing the fast-feed button. Raise the stopper pole
until the desired depth of cut is obtained. The depth of cut
is equal to the distance between the stopper pole and the
stopper block. Stopper pole travel can be checked with
the scale (1 mm per graduation) on the tool body. Minute
depth adjustments can be obtained by turning the stopper
pole (1.5 mm per turn).
The stopper block has the adjusting hex bolts which move
1 mm per turn. They are convenient for making stepped
cuts. To adjust the hex bolt height, turn the hex bolts with
a screw driver or wrench.
Nylon nut (Fig. 2)
By turning the nylon nut, the upper limit of the tool body
can be adjusted. When the tip of the bit is retracted more
than required in relation to the base plate surface, turn the
nylon nut to lower the upper limit.
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. When you wish to cut grooves more than 15
mm deep, make several passes with progressively
deeper bit settings.
• Do not lower the nylon nut too low, or the bit will
protrude dangerously.
• Before operating the tool, check to be sure that the tool
automatically rises to the upper limit.
Switch action (Fig. 3)
CAUTION:
• Make sure that the shaft lock is released before the
switch is turned on.
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.
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. 4)
CAUTION:
• Install the bit securely. Always use only the wrench
provided with the tool. A loose or overtightened bit can
be dangerous.
• Do not tighten the collet nut without inserting a bit or
install smaller shank bits without using a collet sleeve.
Either can lead to breakage of the collet cone.
Insert the bit all the way into the collet cone and withdraw
it very slightly (approx. 2 mm). 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

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. 5)
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
