Planing Operation; Maintenance - Makita M1902 Instruction Manual

Nozzle cleaning
Clean the nozzle regularly.
Use a compressed air to clean the clogged nozzle.
OPERATION
WARNING:
To reduce the risk of injury to
persons, do not operate without nozzle or chip
cover in place.
Hold the tool firmly with one hand on the knob and the
other hand on the switch handle when performing the
tool.

Planing operation

► Fig.11: 1. Start 2. End
Apply the tool front base flat upon the workpiece
surface without the planer blades contacting the work-
piece. Switch on and wait until the blades attain full
speed. Then move the tool gently forward at a uniform
speed. Apply pressure on the front of tool at the start of
planing, and on the rear at the end of planing.
The speed and depth of cut determine the finish. To
obtain a good surface finish, plane deeply until you get
near the desired depth, and then plane thinly and slowly
for the final pass.
Shiplapping (Rabbeting)
► Fig.12
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.13: 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.14: 1. Screw 2. Edge fence
When planing, move the tool with the edge fence flush
with the side of the workpiece. Otherwise uneven plan-
ing may result.
► Fig.15
Maximum shiplapping (rabbeting) depth is 9 mm
(11/32").
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.16
NOTE: The shape of the guide rule is differ from
country to country. In some country, the guide rule is
not included as a standard accessory.
Chamfering
► Fig.17
► Fig.18
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 inspection or maintenance.
CAUTION:
Never use gasoline, benzine, thin-
ner, alcohol or the like. Discoloration, deformation
or cracks may result.
Sharpening the planer blades
For conventional planer blades only
Always keep your planer blades sharp for the best per-
formance possible. Use the sharpening holder (optional
accessory) to remove nicks and produce a fine edge.
► Fig.19: 1. Sharpening holder
First, loosen the two wing nuts on the holder and insert
the planer blades (A) and (B), so that they contact the
sides (C) and (D). Then tighten the wing nuts.
► Fig.20: 1. Wing nut 2. Planer blade (A) 3. Planer
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.22: 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.23: 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.
