[3] -7. Disassembling/ Assembling of Switch Section
Although Switch section can be disassembled, you can also use Switch assembly to entirely replace Switch section.
DISASSEMBLING
1) Remove Clutch case section and Housing (L).
(Refer to [3] -1, 6.)
2) Remove Switch unit in Trigger while expanding
the ribs. (Fig. 27)
3) Switch unit for rotation reverse can be replaced by
removing PT3x16 Tapping screw, then removing
Cover.
Now the following parts can also be replaced:
F/R Change lever, Leaf spring, Switch lever A,
Compression spring A
ASSEMBLING
Put Leaf spring in place on F/R Change lever, and Compression
spring 4 on Switch lever A.
Put F/R Change lever, Switch lever and Switch unit for rotation
reverse in place. At this time, fit the protrusion on F/R Change
lever in Switch lever A. (Fig. 28)
Then, while pushing these parts with Cover, fasten with PT3x16
Tapping screw.
[3] -8. Rotor Handling
Important
Physical contact between Rotors is strictly prohibited as it may cause Rotor quality
disorder due to the following two reasons.
1. Magnetic force decrease caused by physical contact between Rotors
2. Damage or internal cracking of magnet due to strong impact when Rotors smash
sharply each other. (Fig. 29)
Be very careful when placing Rotors together as it has strong magnet force to
attract each other if they are placed nearby.
