OPERATING INSTRUCTIONS

Installing or removing bit

Important:

Always be sure that the tool is switched off and

unplugged before installing or removing the bit.

This tool accepts bits either with or without a collar on its

shank.

Bit with collar (Fig. 1)

Bit without collar (Fig. 2)

To install the bit, follow either procedure (1) or (2)

described below.

(1) For bits with a collar (Fig. 3):

Pivot the tool retainer back and slightly downward. Insert

the bit into the tool holder as far as it will go. To securely

retain the bit, return the tool retainer to its original position.

(a) When the bit is inserted.

(b) When the bit is retained.

CAUTION:

Always assure that the bit is securely retained by

attempting to pull the bit out of the tool holder after com-

pleting the above procedure.

(2) For bits without a collar (Fig. 4):

Pivot the tool retainer forth and slightly downward. With

the notched portion of the bit facing the tool retainer

shaft, insert the bit into the tool holder as far as it will go.

Then pivot the tool retainer further downward toward the

cylinder A to securely retain the bit.

(a) When the bit is inserted.

(b) When the bit is retained.

CAUTION:

• Always assure that the bit is securely retained by

attempting to pull the bit out of the tool holder after

completing the above procedure.

• The bit without a collar cannot be retained by the

method shown in Fig. 3.

Switch action (Fig. 5)

To start the tool, simply squeeze the switch lever.

Release the switch lever to stop.

Operation

Hold the tool firmly with both hands. Turn the tool on and

apply slight pressure on the tool so that the tool will not

bounce around, uncontrolled. Pressing very hard on the

tool will not increase the efficiency.

MAINTENANCE

CAUTION:

Always be sure that the tool is switched off and

unplugged before carrying out any work on the tool.

Replacement of carbon brushes (Fig. 6 & 7)

Whenever carbon brushes must be replaced, they cut out

the tool automatically. When this occurs, remove the motor

housing cover and then replace both carbon brushes at

the same time. Use only identical carbon brushes.

Lubrication (Fig. 8 & 9)

This tool requires no hourly or daily lubrication because it

has a grease-packed lubrication system. It should be

relubricated after every 6 months of operation. Send the

complete tool to Makita Authorized or Factory Service

Centre for this lubrication service. However, if circum-

stances require that you should lubricate it by yourself,

proceed as follows.

First, switch off and unplug the tool. Remove the plate 50

using a screwdriver, then replenish with fresh grease

(60 g). Use only Makita genuine grease (optional acces-

sory). Filling with more than the specified amount of

grease (approx. 60 g) can cause faulty hammering action

or tool failure. Fill only with the specified amount of

grease. Reinstall plate 50 and secure with the screws.

To maintain product safety and reliability, repairs, mainte-

nance or adjustment should be carried out by a Makita

Authorized Service Centre.
