SCRUB BRUSHES

Two disc-type scrub brushes scrub the floor. Each
scrub brush is driven by its own electric motor
through a floating drive assembly. Part of each
floating drive assembly is a spring lock clip which
holds the scrub brushes.

There are many variations of brushes and
cleaning pads to choose from. There is a brush or
cleaning pad available for almost any application.
Scrub brushes are ready for use when they are
equipped with a brush drive plate and spring clip.

Scrub brushes should be checked daily for
tangled wire or string wear damage. Scrub
brushes should be replaced if large portions of the
brush bristles are missing or if the remaining
brush bristle length is less than 0.50 to 0.25 in (15
to 5 mm).

NOTE: Be sure to replace brushes in sets.

Otherwise one scrub brush will be more

aggressive than the other.

TO REPLACE SCRUB BRUSHES

1. Raise the scrub brushes.

2. Turn machine off and set the 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.

3. Remove the scrub head cover by pressing

on the release levers on both sides of the
scrub head cover and pulling forward.
