Maintenance - Makita 3620 Betriebsanleitung

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
with an 8 mm diameter bit.
[Note: When cutting grooves with a 20 mm diameter bit,
the depth of cut should not be more than 5 mm at a pass.]
When you wish to cut grooves more than 15 mm deep
with an 8 mm diameter bit or more than 5 mm deep with
a 20 mm diameter bit, make several passes with progres-
sively deeper bit settings.
Stopper block (Fig. 5)
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 bolts, first loosen the hex nuts on the hex bolts with
the wrench and then turn the hex bolts. After obtaining the
desired position, tighten the hex nuts while holding the
hex bolts in that desired position. The stopper block is
also convenient for making three passes with progres-
sively deeper bit settings when cutting deep grooves.
CAUTION:
When using a bit having total length of 60 mm or more, or
edge length of 35 mm or more, the depth of cut cannot be
adjusted as previously mentioned. To adjust, proceed as
follows:
Loosen the lock lever and carefully adjust bit protrusion
below the tool base to the desired depth of cut by moving
the tool body up or down. Then re-tighten the lock lever to
lock the tool body at that depth of cut. Keep the tool body
locked at this position during use. Since the bit always
protrudes from the tool base, be careful when handling
the tool.
Adjusting the lock lever (Fig. 6)
The locked position of the lock lever is adjustable. To
adjust it, loosen the lock lever 3/4 turn and press the
center of the lock lever. The hex nut will come out. Set the
hex nut to the desired position and tighten the lock lever.
Switch action (Fig. 7)
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the ''OFF''
position when released.
To start the tool, simply pull the trigger. Release the
trigger to stop.
Operation (Fig. 8)
• 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.
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, 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 (Fig. 9, 10 & 11)
The straight guide is effectively used for straight cuts
when chamfering or grooving.
To install the straight guide, insert the guide bars into the
holes in the tool base. Adjust the distance between the bit
and the straight guide. At the desired distance, tighten the
wing bolts to secure the straight guide in place.
When cutting, move the tool with the straight guide flush
with the side of the workpiece.
If the distance (A) between the side of the workpiece and
the cutting position is too wide for the straight guide, or if
the side of the workpiece is not straight, the straight guide
cannot be used. In this case, firmly clamp a straight board
to the workpiece and use it as a guide against the router
base. Feed the tool in the direction of the arrow.
Templet guide (optional accessory)
(Fig. 12, 13 & 14)
The templet guide provides a sleeve through which the bit
passes, allowing use of the router with templet patterns.
To install the templet guide, loosen the screws on the tool
base, insert the templet guide and then tighten the
screws.
Secure the templet to the workpiece. Place the tool on the
templet and move the tool with the templet guide sliding
along the side of the templet.
Vacuum head set (optional accessory)
(Fig. 15, 16 & 17)
When you wish to perform clean cutting operation, use
this vacuum head. Install the vacuum head on the router
base using the two screws and connect a vacuum cleaner
to the vacuum head.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and unplugged
before carrying out any work on the tool.
To maintain product safety and reliability, repairs, main-
tenance or adjustment should be carried out by a Makita
Authorized Service Center.
