HOW THE MACHINE WORKS
The machine is powered by a 36V battery pack (Wet
lead/acid or sealed/AGM batteries). The burnishing
process is accomplished by a high- speed rotating pad
with applied pressure and forward motion creating a
smooth polished floor finish. The push model is
assisted by the rotating pad and the drive model is
equipped with a propel motor. The pad pressure and
burnishing speed can be adjusted for floor type and
floor condition. Depending on model, the pad pressure
is mechanically adjusted or done by an actuator. The
dust is collected with a passive or active dust control
vacuum system. The passive dust control vacuum
system uses centrifugal force from the rotating pad to
create a vacuum for dust collection. The active dust
control vacuum system model consists of a vacuum
motor and a high efficiency HEPA rated filter. The
burnishing function is controlled by a start bail at the
control console.
MACHINE SETUP
INSTALLING BURNISHING PAD
There are many types of burnishing pads to choose
from depending on floor type, finish and floor condition.
Contact an authorized distributor for burnishing pad
recommendations.
Each new machine comes equipped with one
pre- installed burnishing pad.
Replacement Factory Supplied Burnishing Pads:
611788 - 20 in/510mm Hair Blend Burnishing Pad (Qty. 5)
