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 thin-
ner, gasoline, oil or the like.
They may cause cracks in the tool base.
16. Draw attention to the need to use cutters of the
correct shank diameter and which are 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.
SAVE THESE INSTRUCTIONS.
WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.
OPERATING INSTRUCTIONS
Installing or removing the router bit (Fig. 1)
Important:
Always be sure that the tool is switched off and
unplugged from the supply outlet before installing or
removing the router bit.
Insert the router bit all the way into the collet. 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 mount
the appropriate collet, then install the bit as described
above.
CAUTION:
• Do not tighten the collet without inserting a router
bit.
• Use always a collet which is suitable for the shank
diameter of the router bit.
• Use only router bits of which the maximum speed,
as indicated on the bit, does exceed the maximum
speed of the router.
Adjusting the depth of cut (Fig. 2)
Important:
Always be sure that the tool is switched off and
unplugged before adjusting the depth of cut.
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. While pressing the fast-feed button, move the
stopper pole up or down until the desired depth of cut
is obtained. Minute depth adjustments can be
obtained by turning the stopper pole (1.5 mm per
turn).
CAUTION:
The depth of cut should not be more than 20 mm at a
pass when cutting grooves. For extra-deep grooving
operations, make two or three passes with progres-
sively deeper bit settings.

Nylon nut (Fig. 2)
The upper limit of the tool body can be adjusted by
turning the nylon nut. Do not lower the nylon nut too
low. The bit will protrude dangerously.
Stopper (Fig. 3)
As the rotary stopper has three adjusting hex bolts,
you can easily obtain three different depths of cut
without readjusting the stopper pole. To adjust the
hex bolts, loosen the hex nuts on them and turn the
hex bolts. After obtaining the desired position, tighten
the hex nuts to secure the hex bolts.
Switching ON and OFF
For tool without lock-off button (Fig. 4)
CAUTION:
Make sure that the shaft lock is released before the
switch is turned on.
To switch on, move the switch lever to the "ON" posi-
tion.
To switch off, move the switch lever to the "OFF" posi-
tion.
For tool with lock-off button (Fig. 5)
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 switch on, push the lock-off button and at the
same time press the trigger.
To switch off, release the trigger.
Speed change knob (Fig. 6)
For 3612C only
The tool speed can be infinitely adjusted between
9,000 rpm and 23,000 rpm by turning the speed
change knob. 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 below for relation-
ship between the number settings on the speed
change knob and approx. tool speed.

Operation (Fig. 7)
Place the tool on the workpiece and switch on.
Release the lock lever and slowly lower the tool onto
the workpiece until preset routing depth is reached.
Move the tool forward using both hands. When cut-
ting edges, the workpiece surface should be on the
left side of the bit in the feed direction as shown in
Fig. 7.
