Makita 3708 Instruction Manual page 10

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 3 mm at a pass when
cutting grooves. When you wish to cut grooves more
than 3 mm deep, make several passes with progres-
sively deeper bit settings.
Straight guide (Fig. 9, 10, 11 & 12)
The straight guide is effectively used for straight cuts
when chamfering or grooving.
Attach the guide plate to the straight guide with the
bolt, the wave washer, the flat washer and the wing nut.
Loosen the wing bolts and secure the tool base hori-
zontally. Attach the straight guide with the clamp
screw (A). Loosen the wing nut on the straight guide
and adjust the distance between the bit and the
straight guide. At the desired distance, tighten the
wing nut securely.
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 trimmer base. Feed the tool in the
direction of the arrow.
Templet guide (Fig. 19, 20, 21 & 22)
The templet guide provides a sleeve through which the bit passes, allowing use of the trimmer with templet
patterns.
Remove the tool base from the tool. Loosen the wing bolts and secure the tool base horizontally. Loosen the
two screws on the tool base.
Place the templet guide on the tool base. There are four convex portions on the templet guide. Secure two of
the four convex portions using the two screws. Install the tool base on the tool.
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.
NOTE:
The workpiece will be cut a slightly different size from the templet. Allow for the distance (X) between the router
bit and the outside of the templet guide. The distance (X) can be calculated by using the following equation:
outside diameter of the templet guide – router bit diameter
Distance (X) =
10
Circular work (Fig. 13, 14 & 15)
• Circular work may be accomplished if you assem-
ble the straight guide and guide plate as shown in
Fig. 13 or 14.
Fig. 13 for cutting circles between 70 mm and
121 mm in radius.
Fig. 14 for cutting circles between 121 mm and
221 mm in radius.
Note:
Circles between 172 mm and 186 mm in radius
cannot be cut using this guide.
• Min. and max. radius of circles to be cut (distance
between the centre of circle and the centre of bit)
are as follows:
Min.: 70 mm
Max.: 221 mm
Align the centre hole in the straight guide with the
centre of the circle to be cut. Drive a nail less than
6 mm in diameter into the centre hole to secure the
straight guide. Pivot the tool around the nail in clock-
wise direction.
Trimmer guide (Fig. 16, 17 & 18)
Trimming, curved cuts in veneers for furniture and the
like can be done easily with the trimmer guide. The
guide roller rides the curve and assures a fine cut.
Loosen the wing bolts and secure the tool base hori-
zontally. Install the trimmer guide on the tool base
with the clamp screw (A). Loosen the clamp screw
(B) and adjust the distance between the bit and the
trimmer guide by turning the adjusting screw (1 mm
per turn). At the desired distance, tighten the clamp
screw (B) to secure the trimmer guide in place.
When cutting, move the tool with the guide roller rid-
ing the side of the workpiece.
