of the hopper. To rotate the hopper, move the lever forward to the dump position and hold. Release the lever
when the hopper reaches the desired position. The return the hopper after dumping, move the lever back to the
RETURN position. The hopper will rotate back and the hopper will lower to the seated position. Release the

The Hopper Lift/Side Broom lever is located to the left side of
the drive compartment. The lever is a three position control
that operates the hopper lift, side broom and optional left side
broom.

been rotated to clear the body of the sweeper.
The lever is spring centered from the rear position. The center
position turns OFF the side broom (or brooms) and is the
HOLD position when dumping the hopper. The lever is
detonated in the forward position. Move the lever forward to
turn ON the side broom when sweeping or to LOWER the
hopper when dumping the hopper. Move the lever back to

and the middle is lower speed (2050 "no load"
RPMs). "Load" (brooms and/or brushes and/or
dust control operating) and "No Load" (brooms,
brushes & dust control off) RPMs are the same for
gas and LP equipment; there will be a slight drop
between "Load" and "No Load" RPMs with diesels.
Always return the throttle lever to the idle position
before turning off the key to stop the engine.
