Setting the drum lever
When correctly set, the sanding drum grinds equally across the drum width. If this is not the case, then do the following:
Setting the height of the handle shaft
1)
Loosen the lock nut on the threaded rod.
2)
Then turn the domed nut clockwise and the drum will grind more on
the right side.
3)
Turn the domed nut counter clockwise and the
drum will grind more on the left side.
4)
Fix the new level by screwing the locking nut into place.
The height of the handle shaft can be adjusted:
1)
Push the control lever forward and down. Pull up
the sliding sleeve.
2)
Loosen the locking wheel.
3)
Loosen the Allen screws using a 4 mm Allen
wrench.
4)
Pull up the handle shaft to the higher position. Tighten the Allen
screws.
