Replacing Carbon Brushes - Makita KP312 Manual De Instrucciones

For the correct planer blade setting
Your planing surface will end up rough and uneven, unless the blade is set properly and securely. The blade must be
mounted so that the cutting edge is absolutely level, that is, parallel to the surface of the rear base.
Below are some examples of proper and improper settings.
(A) Front base (Movable shoe)
(B) Rear base (Stationary shoe)

Blade height adjustment (Fig. 8)
Blade height adjustment is usually not necessary. How-
ever, if you notice that the blade edge is below the level of
the rear base or protrudes too far from the rear base, pro-
ceed as follows.
Loosen the eight installation bolts and the set plate
screws. Turn the adjusting screws clockwise to retract the
blade or counterclockwise to protrude it. After adjusting
the blade height, tighten the set plate screws and the
eight installation bolts securely.
Hex wrench storage (Fig. 10)
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
Nozzle assembly and joint (Accessory)
(Fig. 11 & 12)
Nozzle assembly and joint are used when connecting the
tool to vacuum cleaner.
When you wish to perform cleaner operation, connect a
vacuum cleaner to your tool.
To connect vacuum cleaner, remove the chip guide from
the tool. Place nozzle assembly and joint in its place and
then tighten screws to secure them.
Connect a hose of vacuum cleaner to the joint.
OPERATION
Planing operation (Fig. 13)
First, rest the tool front base flat upon the workpiece sur-
face without the blades making any contact. Switch on
and wait until the blades attain full speed. Then move the
tool gently forward. Apply pressure on the front of tool at
the start of planing, and at the back at the end of planing.
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 tool more
slowly.

Front roller (Fig. 14)
When performing repeated cuts, the use of the front roller
enables quick and effortless return of the tool toward an
operator by raising the back end of the tool so that the
tool blades do not contact a workpiece and then sliding
tool on the front roller.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.

Replacing carbon brushes

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. (Fig. 15)
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. 16)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-

using Makita replacement parts.
