Maintenance - Makita 1911B Instruction Manual

Adjusting the depth of cut (Fig. 5)
Depth of cut may be adjusted by simply turning the
knob on the front of the machine.
Switch action
CAUTION:
Before plugging in the machine, always check to see
that the switch trigger actuates properly and returns to
the ''OFF'' position when released.
For machine without lock button and lock-off
button (Fig. 6)
To start the machine, simply pull the trigger. Release
the trigger to stop.
For machine with lock button (Fig. 7)
To start the machine, simply pull the trigger. Release
the trigger to stop. For continuous operation, pull the
trigger and then push in the lock button. To stop the
machine from the locked position, pull the trigger fully,
then release it.
For machine with lock-off button (Fig. 7)
To prevent the trigger from being accidentally pulled,
a lock-off button is provided. To start the machine,
press the lock-off button and pull the trigger. Release
the trigger to stop.
Planing operation (Fig. 8)
First, rest the machine front base flat upon the
workpiece surface without the blades making any
contact. Switch on and wait until the blades attain full
speed. Then move the machine gently forward. Apply
pressure on the front of machine at the start of
planing, and at the back at the end of planing. Planing
will be easier if you incline the workpiece in stationary
fashion, so that you can plane somewhat downhill.
The speed and depth of cut determine the kind of
finish. The power planer keeps cutting at a speed that
will not result in jamming by chips. For rough cutting,
the depth of cut can be increased, while for a good
finish you should reduce the depth of cut and advance
the machine more slowly.
Chamfering (Fig. 9, 10 & 11)
To make a cut as shown in Fig. 9, align the ''V'' groove
in the front base with the edge of the workpiece and
plane it as shown in the Fig. 11.

Sharpening the planer blades
(Fig. 12, 13 & 14)
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 only
(Fig. 15 & 16)
When you wish to perform clean planing operation,
connect a Makita vacuum cleaner to your machine.
Install the nozzle assembly (standard equipment) on
the machine using the screws provided. Then connect
a hose of the vacuum cleaner to the nozzle assembly
as shown in Fig. 16.
