[3] DISASSEMBLY/ASSEMBLY
[3] -1. Hammer Case Section
ASSEMBLING
(3) Assemble Bumper to the machine. (Fig. 10)
Fig. 10
Mount Bumper to Hammer case cover
by engaging four inner projections
with four corresponding holes,
and two inner notches
with two corresponding claws.
[3] -2. Rotor
DISASSEMBLING
(1) Remove Bumper and Hammer case cover. Then, after removing Housing (R), separate Motor section from Hammer
case section. (Figs. 2 and 3)
(2) Rotor can give damage on the coil of Stator complete when pulling it off from Stator complete because Rotor attracts
Stator complete with its very strong magnetic force.
Therefore, Rotor must be removed from Stator complete as drawn in Fig. 11 to protect Stator complete from damage.
Fig. 11
1. Put the Motor section on a workbench so that the drive end of Rotor
touches the work bench. Then separate Stator complete from Rotor
by pulling it down towards the workbench.

Caution for Handling of Rotor
When handling or storing multiple Rotors, be sure to keep a proper distance between Rotors as shown in Fig. 12.
Because Rotor is a strong magnet, failure to follow this instruction could result in:
Finger injury caused by pinching between Rotors pulling each other
Magnetic loss of Rotors or damage on the magnet portion of Rotor. (Fig. 13)
