2.1   Attach the Power Cord

The triple-wire grounded power cord has been factory-

installed into the handle tube. A flexible rubber cable 

connector (11) is used to secure the plug-in connections. 

The burnisher ships with this connector mounted on the cord 

coming out of the handle (10). 
Stretch the connector and slip the male connector (9) 

(coming out of the motor housing) through the connector 

hole and then into the female connector. Now, plug the end 

of the 50-foot cord into a grounded power outlet. Squeeze 

the triggers on the handle and check for power to the motor.

2.2   Inspect the Pad Driver

A flexible, high-speed pad driver has been bolted onto the burnishing machine and 

dynamically balanced. This driver is the connection between the burnisher and a 

disposable pad that burnishes the hard floor finish. If this molded plastic part ever 

becomes damaged or if the molded hooks are worn 

and cannot hold the pad, replace promptly.
Unplug the burnishing machine. Lock the handle 

in the “up” position and tip the machine back fully.
Remove the 4 mounting screws (11) and washers 

(12) from the drive hub (13). 
Place the new pad driver (14) onto the main drive 

pulley. Insert the mounting screws (11) through the 

washers (12) into the bolt hole. Tighten securely.

2.3   Install the Pad

The face (bottom) of the pad driver (14) is covered with small “hooks” that grab onto the 

pad (16). Every time you mount a new pad onto the pad driver, follow these steps:
•  Unplug the burnishing machine. Lock the handle in the “up” position and tip the 

machine back fully.

•  Pad Sizes: 20” diameter pad on the 20” and 21” 

machines. Mount a pad (16) over the male shoulder 

(15) on the pad driver. Make sure that the pad is 

centered on the driver.

•  Insert the locking ring (17) through the center hole in 

the pad and into the shoulder. Tighten until the locking 

ring lies below the face of the pad. If the ring is not 

fully locked, it will scratch the floor.

NEVER operate the burnisher without a pad.
NEVER operate the burnisher with a damaged pad of without a locking ring to hold the 

pad in place.
