Spur gears
Rotor’s gear
3 Before pushing Rotor section (Rotor and Stator) fully
in Gear assembly, make sure that Rotor’s gear engages
with the super gears of Gear assembly to rotate them smoothly.
(1) Assemble Gear assembly and Rotor section in the reverse order of disassembly. (Refer to
Figs. 9 and 8
)
Note
: Be careful not to pinch your fingers between Stator and Rotor’s fan when assembling Rotor. (
Fig. 11
)
1. While holding Stator on workbench, insert Rotor into Stator
slowly until the drive end of Rotor reaches the workbench.
2. When the drive end of Rotor reaches

1. Apply the front Compression
spring 4 of Speed change lever
assembly to the flat side
(without pin) of Gear assembly
for Speed change.
2. Push Speed change lever assembly
toward Rotor side until it stops to
have space between the pin of
Gear assembly and the rear
Compression spring 4.
3. Fit the pin of Gear assembly to
Spring’s coil with slowly
returning Speed change lever
assembly toward Drill chuck side.
Space between the rear Compression
spring 4 and the pin on the lever of
Gear assembly.
Pin on the lever of Gear assembly fit to
the coil of the rear Compression spring 4
4. Slide Speed change lever
assembly to the either position
2 (High speed mode) or
1 (Low speed mode).
