Operation Timing After Replacing the Main Motor
CAUTION:
Turn OFF the power switch before starting to replace and adjust the main motor.
•
To adjust the timing of the scooping block in respect to the brush movement, it is
necessary to adjust the gear engagement.
•
When the motor has been removed from the main body, adjust the gear engagement of
the motor, as shown in the figure below then the operation timing can be adjusted. After
assembling the motor, be sure to tighten the screws again.
•
When it is hard to engage the driving gear, of the motor with the driven gear, loosen the
drive shaft bracket (right) then this will facilitate the assembly. (Refer to the figure on the
below.)
•
After installing the motor, switch the power ON to check the operation timing. (Check
that both right and left scooping blocks operate almost simultaneously.)
•
After doing an operation check, return the wiring arrangement to its original status.
When installing the cover, be careful not to pinch any wires. Be careful that the wiring
does not hinder the operation of moving parts. The wiring, on the inside, should not
hinder adjustments made from the outside of the machine.
NOTE:
To avoid breakage, do not use excessive force with the motor wiring.
Assemble the motor section when the
scooping blocks left, and right are in the
lowest position.
To get the left and right scooping blocks at
almost the same height, clinch the drive
gear of the motor shaft and the gears on the
left and right, and tighten the motor
bracket.
(M2.6 x 8 - 2 pieces)
The left and right scooping blocks
should be at the lowest position.
When the right pin
is vertical, the left
pin
should
be
inclined about 46°.
