[3] -2. Replacing Switch, LED circuit and Terminal

(1) Do the steps (1), (2), (3) and (4) of the previous page.
(2) Insert Battery and pull the trigger to locate Hammer at
lowest position to release tension of Compression spring 17.
Remove Battery after this procedure is finished.
Go to the next step without changing spring position
in case Switch or DC motor is disorder.
(3) Separate housing R by removing Tapping screws and Pan head
screws drawn in Fig. 9 while holding trigger section
to prevent spring from jumping out.
(4) Switch, LED circuit and Terminal now can be removed.

[3] -3. Replacing Motor

(1) Remove Front cover and Housing R as drawn in Fig. 2 and Fig. 9.
(2) Remove M4x6 Hex socket head bolt. Pull out Upper rail complete, and then separate Magazine ass'y from Housing L

(3) Dismantle Housing R by removing 8 pcs. of Bind PT3x16 Tapping screws, 2 psc of M4x14 Pan head screw and
a M4x35 PAn head screw. Now DC motor can be removed provided Compression spring 17 has no tension.
(4) When Motor or Switch is out of order, Hammer of Spring section often stops in the halfway position and
Compression spring 17 remains compressed. It is impossible to remove DC motor from Housing L.
In this condition, remove 2pcs. of Bin PT3x16 Tapping screw (Fig.11), and insert slotted screwdriver into the gap
between Housing L and Rail of Spring section, and then lever up Spring section with the slotted screwdriver

(2) Mount the following parts on Housing L (Fig. 27);
Spur gear 55 complete, Cam block section, Lock arm section and two Leaf springs

Note: When disassembling Lock arm section, do not remove M3x4 Pan head screw. It becomes easy to set gear
section in place.

Regarding two Leaf springs, install them in the space for Internal gear 69 as drawn in Fig. 28.
(3) Face the rim portion of Internal gear 69 oposit side of DC motor and assemble Internal gear section (Fig. 29).
(4) Install Anti back plate to Spur gear 7 complete with the direction described in Fig. 30
and mount them in Housing L. (Fig. 31) Be sure to put Roller portion of Spur gear 55 complete under
the hook of Hammer.
