1) -4. Disassembling Hammer and Spindle Section
(1) Press down hammer with Large gear extractor (1R045) by turning the handle. (Fig. 8)
(2) Adjust the opening for steel ball insertion to the top of cam groove on spindle. (Fig. 8)
(3) Remove 2 pcs of steel ball 5.6 from spindle. (Fig. 8)
(4) Hold the hammer section as illustrated in Fig. 9, and then loose the handle of large gear extractor.
Caution: Do not hold gear extractor as illustrated in Fig. 8 when loosening the handle of gear extractor.
Failure to follow this instruction could cause steel balls 3.5 to get out of hammer.
(5) Now hammer section can be disassembled as illustrated in Fig. 10.
(6) After removal of flat washer 24, steel balls 3.5 can be removed from hammer. (Fig. 11)

2) Assembling
2) -1. Assembling Sleeve Section
Do the reverse of disassembling procedure.
2) -2. Assembling Hammer and Spindle Sections
(1) Before assembling the parts, apply Makita grease N. No.2 to the following parts.
* Top of the spindle where anvil contacts: approx. 0.5 g
* 2 pcs of steel ball 5.6: approx. 0.5 g
* 24 pcs of steel ball 3.5 which are mounted to hammer: approx. 0.5 g
* 2 pcs of spur gear 22: approx. 2.0 g
(2) And then do the reverse of disassembling procedure. (Fig. 11, 10, 9 and 8)
Note: Make sure that all of 24 steel balls (size = 3.5) are installed on hammer. (Fig. 11)
2) -3. Assembling Housing
When assembling the housing, be sure to follow the instructions below.
1. Before mounting the internal parts, make sure that rubber pin 4 is installed on
each of housing R and L. ( Fig. 12)
2. When mounting FET and FET spacer to yoke unit, tighten a ST3x8 tapping screw
to the recommended torque of 1.1 - 1.5N.m (11 - 15kgf.cm). (Fig. 13)
3. When fastening housing R to housing L, tighten each of eight PT3x16 tapping screws
to the recommended torque of 1.1 - 1.3N.m (11 - 13kgf.cm). (Fig. 14)
4. When mounting LED circuit section, tighten a tapping screw PT3 x 10
to the recommended torque of 0.54 - 0.66N.m (5.3 - 6.5 kgf.cm).

2) -4. Assembling Hammer Case to Housing
(1) When mounting internal gear case to housing, be sure to follow the instructions below. (Fig. 15)
* Always use brand-new M4x12 pan head screw.
* Tighten each of four M4x12 pan head screws to the
recommended torque of 0.88 - 1.8 N.m (9.0 - 18 kgf.cm).
(2) Fit socket 30-78 (Part No.134847-1) over the hex portion of hammer case, and then tighten
the socket to the recommended torque of 25 - 30 N.m (260 - 310 kgf.cm). (Fig.16)
Caution:
Do not fail to install anvil on hammer case before fastening hammer case to housing.
