Please read and adhere to all of the following Instructions before operating propane equipment.

1 The fuel supply system and cylinder connections of the floor maintenance machine shall be checked for leakage

immediately after a cylinder is connected.

2 Connection and disconnection of cylinders shall be done in a well ventilated area with no source of ignition with

10 ft. (3m) from the point of connection. 3 When the engine of a floor maintenance machine is running the operator shall not leave the unit unattended. 4 When a floor maintenance machine is not in use and stored indoors, the cylinder shall be removed and stored

outdoors and protected from damage and tampering. 5 A sign indicating “NO SMOKING” shall be permanently displayed at the storage area. The sign shall be in

accordance with the sign required In Clause10.12.3 of CAN/CGA-b149.2-M91, Propane Installation Code. (Does not

apply in industrial buildings). 6 When the cylinder is attached to the floor maintenance machine for use, the operator shall not leave the unit

unattended except for short periods of time such as rest stops, washroom or meal stops. 7 A floor maintenance machine shall only be used In buildings:

a. provided with continuous mechanical ventilation that removes the products of combustion to the outdoors of not

less than 300 CFM for each 10,000 Btu input or fraction thereof;

b provided with natural ventilation of not less than 300 CFM for each 10,000Btu input or fraction thereof, based on

a maximum of one quarter air change per hour for the net building volume.

8 The owner of a floor maintenance machine must ensure that the operator has participated in a course authorized

by the manufacturer of the unit on the safe handling of propane and the safe operation of the machine. 9 The owner of a floor maintenance machine shall ensure that the unit is maintained in accordance with the

manufacturer’s recommended maintenance procedures in a safe operating condition and the owner shall

maintain a record of the maintenance for a period of two years. 10 Before transporting a floor machine, the cylinder shall be securely fastened, with the system valve closed and the

cylinder shall be located in a well ventilated space.

4 Clean all air filters by blowing out dust and dirt and/or washing

the foam filters (recoil and carburetor pre- filter) with warm, sudsy water and rinsing clean.

(Be careful not to wet the paper

The following information refers to United States regulations on propane. For outside the United States, owner, must assure that required regulations are met.

The manufacturer would like to acknowledge NFPA 58, Standard for Storage and Handling of Liquefied Petroleum Gases, 1993 Edition. This publication is available through the National Fire Protection Association (NFPA) in Quincy, Massachusetts (1-800-344-3555). The NFPA was established to set guidelines for, among other things, the use of propane.

Propane is a flammable gas whose vapors are heavier than air. It can explode under certain conditions. It is not different than other items commonly used today which must be operated in a safe way such as automobiles, gas stoves, airplanes, etc. Propane is odorized with an agent with a distinct odor that is recognizable at very low concentrations. This helps in identifying leaks even when they are small.

Awareness and basic safely precautions are required. As long as these precautions are followed, risk is negligible. Ignorance, however, could pose needless risk. Therein lies the reason behind NFPA 58 and the Safety Publication.

NFPA 58 categorizes propane-powered buffers with fork lift trucks, (see section 3-6.4.4). In essence, the only difference between the two lies in the ability of the buffer with its 20-pound tank to be stored in concealed areas (like janitor closets, etc.).

If a machine and its tank of propane were stored in a closet and afire occurred, the propane in the tank could be a threat to fire fighters due to the potential for a B.L.E.V.E. (Boiling Liquid Expanding Vapor Explosion). Exposure of the tank to heat can also cause the relief valve to open thereby releasing flammable vapors that can cause the fire to intensify when ignited.

The NFPA Technical Committee prohibits the storage of such containers in buildings.

NOTE:

See

‘INSTALLING OR CHANGING LPG FUEL TANK” for Tank

Removal.

The LP gas tank supplied with machine has a 20Ib. (9.3kg), 5-gallon (18.9L) capacity.

DO NOT OVERFILL. DO NOT OVERFILL.

DO NOT OVERFILL. Overfilling will cause the regulator to freeze up. Use only D.O.T. and U.L. Listed propane tank and only fill tank at a reputable propane dealer .

DO NOT attempt to repair the propane tank yourself. Return tank to dealer for repair.

NOTE:NOTE:

NOTE: Never use a tank not intended for the propane machine. Do not substitute tanks from barbecue grills, etc.

The manufacturer exclusively uses aluminum and steel cylinders that meet the Department of Transportation guidelines contained in the D.O.T. # 4ET240 and are additionally U.L. listed.

NFPA 58 discusses the major concerns for filling tanks properly in Chapter 4. In summary, the tank should never be completely filled with liquid. A tank that is completely full could create a hazard. The hazard is known as a hydrostatic pressure situation.

To illustrate this situation, suppose the temperature outside is very cold (perhaps well below freezing). You fill your tank outside and then bring it inside where the temperature is maybe 60 degrees Fahrenheit or warmer. An increase in air temperature will drive up the cylinder pressure placing stress on the tank. Before reaching a critical pressure point, the relief valve should open, relieving the pressure by venting vapor at the top of the tank. However, if there is no vapor at the top of the tank, this safety measure is compromised. Overfilled tanks do not allow this built-in safety feature to function properly.

TTENTION!TTENTION!

TTENTION!

Overfilling a tank usually results in liquid flowing through the hose and down into the regulator. This can result in damage to the machine.

If you observe frost on the regulator, someone has overfilled the tank. Take the tank to a safe outside location and vent the excess propane. Venting is accomplished by:

1 Removing the tank from machine. 2 Taking tank outside of building to safe area. 3 Opening the small relief valve located on top of machine. 4 Keep tank upright. 5 Allow to vent until fuel vapor is not visible.

Whether the tank is filled by weight (most accurate) or by volume, using a gage, make sure the person doing the filling is qualified.

CAUTION!CAUTION!

CAUTION!

Avoid overfilling tanks. Only fill to 80% of capacity. The manufacturer recommends that refueling be accomplished by qualified personnel away from public buildings outside. We further recommend that additional tanks be used so that rather than refueling at the job site, a simple exchange of tanks occurs.

TTENTION!

Tanks (20Ib.) should not be stored in buildings used by the public or frequented by anyone passing through or working in the building. Inside storage in buildings designated as shop or machinery facilities are acceptable.

Section 5-2.1.1 of the NFPA 58 says: “Containers in storage shall be so located as to minimize exposure to excessive temperature rise, physical damage or tampering.”

Provision must be made for venting the actual storage area with both floor level and high level openings. This venting assures that the heavier than air propane gas will not settle in pockets, but disperse.

If storage is in a shop or machine storage area that is connected or a part of an office complex, it should be separated by afire wall along with proper venting to the outside.

Since these requirements can seldom be found, outside open air storage is the most practical alternative.

When this option is used, the storage container may be located with “zero” clearance from the building and with at least 5' of space between the cage and the nearest building opening.

The tank must be in a secure, tamper-proof security storage enclosure that provides safety from accident or vandalism.

CAUTION!CAUTION!

CAUTION!

Tanks must always be stored in the upright position. The upright position assures that the discharge is largely vapor rather than liquid. This is important from the standpoint of both the quantity of the potential flammable vapor/air mixture and the relieving capacity for the pressure relief device. (The escape of vapor presents much less hazard than the escape of liquid).

The manufacturer recommends that tanks be removed from the machine after use and stored accordingly. The machine can then be placed in a secure area inside, away from the tank.

NOTE: NOTE:

NOTE: Local jurisdiction always prevails there may. Be varying requirements. Always check with the local authorities.
