DISASSEMBLING

ASSEMBLING

Fig. 1

Fig. 2

M6x22 - Flat head screw
(left-hand screw)

Note: It is required to remove Drill chuck when replacing Gear assembly,
but you need not when replacing the parts that are independent of
Gear assembly.

(1) Open the jaws of Drill chuck fully, and turn M6x22 - Flat head screw
(left-handed and threadlocker coated) clockwise with Slotted screwdriver.
When it is difficult to remove the screw, use Vise and Impact driver. (Fig. 1)
(2) Set the machine to drill mode, low gear mode and reverse rotation mode.

(3) Hold the long side of Hex wrench 8 in Vise and secure the short side to Drill

chuck firmly as drawn in Fig. 2.
(3) Pull Switch trigger slowly.

Important:
Be sure to hold the grip of Machine tightly with sufficient counterclockwise*
force against clockwise* recoil force of the machine.
Note: The rotational direction marked with * is viewed from operator.

(4) Spindle rotates counterclockwise* and consequently Drill chuck is removed from spindle.
When the above way is not effective, use 1R359 to remove Drill chuck. Refer to Makita repair tool list.

(1) Seat Drill chuck on Spindle.
(2) Set the machine to Drill mode, Low gear mode and Forward rotation mode.

(3) Hold the long side of Hex wrench 10 in Vise and secure the short side to Drill chuck firmly. And then tighten Spindle
into Drill chuck by pulling the trigger of Switch slowly at first and to the full speed in one second not to give impacts
carefully.

Note: Release the trigger of Switch just after Spindle is locked. Do not keep on pulling the trigger for longer
than one second.

(4) Fasten Drill chuck to Spindle with M6x22 - Flat head screw by turning it counterclockwise.

Note: If you reuse the screw removed from Drill chuck, apply an appropriate amount of adhesive
(ThreeBond 1321B/ 1342 or Loctite 242) to the thread for secure fastening.

Hold the flats of this long end in vise.

Do not hold the edges.
