Maintenance; Optional Accessories - Makita N1923B Instruction Manual

Shiplapping (Rabbeting)
► Fig.13
To make a stepped cut as shown in the figure, use the
edge fence (guide rule).
Draw a cutting line on the workpiece. Insert the edge
fence into the hole in the front of the tool. Align the
blade edge with the cutting line.
► Fig.14: 1. Blade edge 2. Cutting line
Adjust the edge fence until it comes in contact with the side
of the workpiece, then secure it by tightening the screw.
► Fig.15: 1. Edge fence 2. Screw
When planing, move the tool with the edge fence flush
with the side of the workpiece. Otherwise uneven plan-
ing may result.
Maximum shiplapping (rabbeting) depth is 23 mm.
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).

► Fig.17
CAUTION:
• The blade edge should be made to protrude
outside slightly (0.3 mm - 0.6 mm). Otherwise,
nicks and generally poor shiplapping results.
► Fig.18
Chamfering
To make a chamfering cut as shown in the figure, align
the "V" groove in the front base with the edge of the
workpiece and plane it.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
Sharpening the planer blades
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.
► Fig.21: 1. Sharpening holder
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.
► Fig.22: 1. Wing nut 2. Blade (A) 3. Blade (B) 4. Side
(D) 5. Side (C)
Immerse the dressing stone in water for 2 or 3 minutes
before sharpening. Hold the holder so that the both
blades contact the dressing stone for simultaneous
sharpening at the same angle.

Replacing carbon brushes
► Fig.24: 1. Limit mark
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 chip cover or nozzle.
► Fig.25: 1. Chip cover or Nozzle 2. Screwdriver
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.
