Maintenance - Makita 3709 Instruction Manual

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 clockwise direction.
(Fig. 15)
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. (Fig. 16)
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 turn-
ing the adjusting screw (1 mm per turn). At the desired
distance, tighten the clamp screw (B) to secure the trim-
mer guide in place. (Fig. 17)
When cutting, move the tool with the guide roller riding
the side of the workpiece. (Fig. 18)

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
Replacing carbon brushes
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes. (Fig. 19)
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps. (Fig. 20)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized or Factory Service Centres,
always using Makita replacement parts.
