Maintenance - Makita N1923BK Instruction Manual

Shiplapping (Fig. 12, 13, 14 & 15)
To make a stepped cut as shown in Fig. 12, use the
edge fence.
Draw a cutting line on the workpiece. Insert the edge
fence into the hole in the front of the machine. Align
the blade edge with the cutting line.
Adjust the edge fence until it comes in contact with the
side of the workpiece, then secure it by tightening the
screw.
You may wish to add to the length of the fence by
attaching an extra piece of wood. Convenient holes
are provided in the fence for this purpose, and also for
attaching an extension guide (optional accessory).
NOTE:
When planing, move the machine with the edge fence
flush with the side of the workpiece. Otherwise
uneven planing may result.
Max. shiplapping depth is 23 mm.
Chamfering (Fig. 16, 17 & 18)
To make a cut as shown in Fig. 16, align the ''V''
groove in the front base with the edge of the work-
piece and plane it as shown in the Fig. 18.
Nozzle assembly (optional accessory)
(Fig. 19 & 20)
Use of the special nozzle assembly will minimize chip
scatter, making for a cleaner work area.
The nozzle assembly may be attached after the chip
cover on the machine body is removed. When slip-
ping on the assembly, fit the pin on it into the rear
cover hole. Use the chip cover screws to fasten it in
place.
Sharpening the planer blades
(Fig. 21, 22 & 23)
For standard blades only
Always keep your blades sharp for the best perfor-
mance possible. Use the sharpening holder to
remove nicks and produce a fine edge.
First, loosen the two wing nuts on the holder and
insert the blades (A) and (B), so that they contact the
sides (C) and (D). Then tighten the wing nuts.
Immerse the dressing stone in water for 2 or 3
minutes before sharpening. Hold the holder so that
the blades both contact the dressing stone for simul-
taneous sharpening at the same angle.
Connecting a vacuum cleaner
For European countries and areas (Fig. 24)
When you wish to perform clean planing operation,
connect a Makita vacuum cleaner to your machine as
shown in Fig. 24.
For other countries and areas
A nozzle and joint (optional accessories) are neces-
sary to connect a Makita vacuum cleaner to your
machine. Consult a Makita catalogue or representa-
tive on the nozzle and joint.

MAINTENANCE

CAUTION:
Always be sure that the machine is switched off and
unplugged before carrying out any work on the
machine.
Replacement of carbon brushes
(Fig. 25, 26 & 27)
Replace carbon brushes when they are worn down to
the limit mark. First, remove the chip cover and then
replace the carbon brushes. Both identical carbon
brushes should be replaced at the same time.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by
Makita Authorized Service Center.
