IDEA NOTE
A handle is used for manual height adjustment
Manual height adjustment is made easy using handle.
IDEA NOTE
Synchronizing height adjustment
Push bolts and cams are used for synchronized height adjustments.
IDEA NOTE
Simplifying brush replacement
The brush section is designed with a mechanism to be removed together with the shaft in order to simplify brush replacement.
1. Remove the mounting screws of parts No. 218 and 220, and slide No. 220 to left to pull the right end from part No. 218.
2. Remove all the parts that are installed on part No. 226. The bearing, oil seal and collar are to be pulled out to the left side.
3. This enables part No. 220 to be tilted, allowing its left end to be pulled from part No. 226 by moving it to the right (motor) using a small clearance.
