MACHINE OPERATION
3. Press and hold the top of the bumper raise/lower switch
(left switch). Release the switch when the bumper is at the
desired height.
4. Press and hold the top of the hopper raise/lower switch
(center switch). Release the switch when the hopper is at
the desired height.
WARNING
Raised bumper of hopper may fall. Insert squeegee lift
and hopper safety pins.
Note
: There is an upper, middle, and lower safety pin hole in
each support tube. The upper holes are used when the bum-
per and hopper are in the fully raised position. The lower holes
(“maintenance” position) are used when it is desirable during
maintenance to have the bumper or hopper in a lower more ac-
cessible position.
1. Remove the bumper lift safety pin from the back of the right
side support tube.
2. If the bumper is fully raised, insert the safety pin into the
upper hole. If the bumper is raised to one of the lower
“maintenance” positions insert the safety pin into the
appropriate lower hole.
