ORBITAL PADS & CHEMICAL-FREE FINISH REMOVAL (CFR)

NOTE

: Do not lower the orbital head without a pad installed. Doing so may damage the Mighty-Lok

®

 face. 

STANDARD CLEANING OPERATIONS

STANDARD CLEANING OPERATIONS

1.  Align the corners of the pad to the corners of the aluminum plate and press to attach.

2.  Lower the scrub deck onto the pad.

3.  Ensure the pad is properly aligned front-to-back and left-to-right.

CHEMICAL-FREE FINISH REMOVAL (CFR) PAD ASSEMBLY

CHEMICAL-FREE FINISH REMOVAL (CFR) PAD ASSEMBLY

A specialized surface preparation pad, in addition to the traditional cleaning pad, is required for chemical-free 

finish removal. The traditional pad acts as a “backer pad” and compensates for variances in the floor.
1.  Place the black retainer pad 2” back from the front of the red 

scrub pad and the maroon CFR pad to allow water saturation.

2.  Align and assemble the pads with the red pad on top and the 

maroon pad on the bottom facing the floor.

3.  Ensure the gap mentioned in step 1 is facing forward and refer 

to steps 1-3 of “

Standard Cleaning Operations

” above to 

install the CFR Pad Assembly.

MACHINE SETUP

MACHINE SETUP

1.  Install the CFR Pad Assembly as described above.

2.  Fill the solution tank with clean water.

3.  Set the down pressure to Heavy (see “Selecting Down Pressure” above).

4.  Set the solution flow to midrange. Adjust as needed for maximum finish removal, using the least amount of 

water needed for effective rinsing. 

5.  Adjust the machine speed as required.
