10. Before using the tool on an actual workpiece, let
it run for a while.
Watch for vibration or wobbling that could indi-
cate improperly installed bit.
11. Be careful of the bit rotating direction and the
feed direction.
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 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 sur-
face. 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).
6
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 progressively
deeper bit settings.
Nylon nut (Fig. 2)
The upper limit of the tool body can be adjusted by turn-
ing 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" position.
To switch off, move the switch lever to the "OFF" position.
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
–1
9,000 min and 23,000 min
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 relationship 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 work-
piece until preset routing depth is reached. Move the tool
forward using both hands. When cutting edges, the work-
piece surface should be on the left side of the bit in the
feed direction as shown in Fig. 7.
