SCRUB HEAD
SCRUB HEAD
The scrub head houses the two scrub brushes,
and their drive and lift mechanisms. The scrub
head has one adjustment – scrub head leveling. It
is factory adjusted and should not be changed
unless scrub head parts are damaged or are
replaced. If the scrub head is not level, the
brushes will apply uneven pressure and may
bounce. It also would cause excessive wear on
the brush drive plugs and bearings.
TO LEVEL SCRUB HEAD
1. Stop the machine on a smooth, level floor.
2. Lower the scrub brushes.
3. Turn the machine off and set the machine
parking brake, if equipped.
FOR SAFETY: Before Leaving Or Servicing
Machine; Stop On Level Surface, Set Parking
Brake (If Equipped), And Turn Off Machine
And Remove Key.
4. Remove the scrub head cover by pressing
on the release levers on both sides of the
scrub head cover and pulling forward.
