This machine is manufactured for

commercial use only

This machine is designed and manufactured for indoor
use in burnishing wax coated hard floor surfaces.
CleanFreak does not recommend use of this machine
in any environment other than an indoor environment.
This propane powered floor machine is designed and
manufactured for commercial floor burnishing only. This
machine is designed to burnish most modern types of
floors including composition tile, stone, marble, terrazzo,
and resilient floor covering, and some coated wood
floors. Even though NFPA 11.13.2.3 says...”the use
of floor maintenance machines in buildings frequented
by the public, including the times when such buildings
are occupied by the public, shall require the approval of
the authority having jurisdiction.” CleanFreak suggests
usage when occupancy of a given work area is minimal.

These machines should not be used

l In nursing homes, hospitals, day-care centers, etc.

that are occupied.

l By unqualified or untrained personnel.
l Unless properly maintained and adjusted.
l On areas with obstructions such as thresholds, floor

outlet boxes, etc.

l In areas where loose debris or other objects are

present.

l In rooms and areas without proper ventilation.

Refueling and Storage of Fuel Cylinders

This machine uses a 20lb (9.1kg) capacity aluminum or
steel cylinder, which meets the DOT 4E240 standards.
These cylinders are also listed by UL. In addition, the
steel cylinder meets European TPED specifications
and is CE compliant. Filling should be done ONLY
by a qualified propane dealer. FILL THROUGH THE
SERVICE VALVE ONLY. A properly filled cylinder should
not exceed 80% of the rated capapcity.

DO NOT attempt cylinder repair. Return the cylinder to
your propane dealer if repair is necessary. Please note
that DOT regulations prohibit shipping of cylinders after
the cylinder has been filled with propane. When not in
use, cylinders should always be stored outside in an
upright position in a secure, tamper-proof, steel mesh
storage cabinet. The cabinet may be located next to
the building, but with at least five feet (1.5 m) of space
between the cabinet and the nearest building opening
(door or window).

The cylinder to be used on this machine is a vapor
withdraw cylinder. A liquid withdraw cylinder is not
to be used with this machine. The use of a liquid
withdraw cylinder on a vapor withdraw system could
freeze the regulator and create a fire hazard. The
National Fire Protection Association (NFPA) Standard
for Storage and Handling of LP Gas is the appropriate
authority for safe propane use. A copy of this publication
