Router Safety Warnings; Functional Description - Makita 3612 Instruction Manual

ROUTER SAFETY WARNINGS

1. Hold power tool by insulated gripping surfaces,
because the cutter may contact its own cord.
Cutting a "live" wire may make exposed metal parts of
the power tool "live" and shock the operator.
2. Use clamps or another practical way to secure and
support the workpiece to a stable platform. Holding
the work by your hand or against the body leaves it
unstable and may lead to loss of control.
3. Wear hearing protection during extended period of
operation.
4. Handle the bits very carefully.
5. Check the bit carefully for cracks or damage
before operation. Replace cracked or damaged bit
immediately.
6. Avoid cutting nails. Inspect for and remove all
nails from the workpiece before operation.
7. Hold the tool firmly with both hands.
8. Keep hands away from rotating parts.
9. Make sure the bit is not contacting the workpiece
before the switch is turned on.
10. Before using the tool on an actual workpiece, let it
run for a while. Watch for vibration or wobbling
that could indicate 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 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.
SAVE THESE INSTRUCTIONS.
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)
GEB018-4
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
adjusting hex bolt. The stopper pole can be moved rapidly
by depressing the fast-feed button. While pressing 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 adjusting hex
bolt. 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).
Now, your predetermined depth of cut can be obtained by
loosening the lock lever and then lowering the tool body
until the stopper pole makes contact with the adjusting
hex bolt.
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 20 mm at a pass when cutting
grooves. When you wish to cut grooves more than 20
mm deep, make several passes with progressively
deeper bit settings.
• Do not lower the knob too low. The bit will protrude
dangerously.
For the tool with knob (Fig. 2)
By turning the knob, 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
knob to lower the upper limit.
For the tool with nylon nut (Fig. 3)
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 block (Fig. 4)
The stopper block has three adjusting hex bolts which
raise or lower 0.8 mm per turn. You can easily obtain three
different depths of cut using these adjusting hex bolts
without readjusting the stopper pole.
Adjust the lowest hex bolt to obtain the deepest depth of
cut, following the method of "Adjusting depth of cut".
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.
