OPERATION

Grip the workpiece in the vise. Use spacer blocks or
pieces of scrap to prevent deformation of the aluminum
workpiece if necessary. Operate the two feed handles
when cutting the workpiece. For better cutting action, coat
the aluminum workpiece with the oil provided. (Fig. 4)
CAUTION:
• Never apply the oil when the bit is rotating.
When cutting rectangular cutouts, proceed as follows.
1. Hold the crank handle with your right hand and loosen
the knob with your left hand.
2. Hold the transvers feed handle with your left hand so
that the table (bed) does not move. Turn the crank
handle to drill a hole in the workpiece.
3. Tighten the knob to secure the motor in this position.
Then operate the two feed handles to cut the rectan-
gular cutouts.
Angle gauge (Fig. 5)
Use the angle gauge for the angle work. Secure it to the
table (bed) using the wing nut. Then fasten the workpiece
in position as shown in the figure. If the workpiece is big or
long, remove the chip guard (chip deflector).
Adjusting for smooth motor travel (Fig. 6)
If the motor does not travel smoothly, proceed as follows.
1. Loosen the screw (A).
2. Tighten the screw (B) (2 pcs.) evenly until you cannot
turn the crank handle easily.
3. Tighten the screw (A) until you can turn the crank han-
dle smoothly.
NOTE:
• Clean the contacting portions and occasionally lubri-
cate them.
Adjusting for smooth table (bed) travel
(Fig. 7)
If the table (bed) does not travel smoothly in the longitudi-
nal direction, tighten the brake screw accordingly.
Using as a trimmer (Fig. 8)
To use as a trimmer, remove the motor from the tool and
attach the trimmer base assembly (optional accessory) to
the motor as shown in the figure.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
Replacing carbon brushes (Fig. 9)
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.
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. 10)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
