Safe Operating Practices

Training

What is LPG? LPG stands for liquefied petroleum gas and is more commonly called propane. LPG is a liquid fuel that is stored in a tank under pressure. Before the liquid leaves the tank, it is converted into a vapor. Since LPG is stored as both liquid and gas, it may leak from joints or connections that are not sealed properly. LPG becomes flammable when it is mixed with air.

The LPG information in this Operator’s manual is provided only as a guide. Consult the NFPA 58: Liquefied Petroleum Gas Code, 2008 Edition for additional safety information. This National Fire Protection Association (NFPA) code pertains to the handling, storing, transporting, and usage of LPG.

Read the Operator’s Manual and other training material. If the operator(s) or mechanic(s) can not read English it is the owner’s responsibility to explain this material to them.

Become familiar with the safe operation of the equipment, operator controls, and safety signs.

All operators and mechanics should be trained. The owner is responsible for training the users.

Never let children or untrained people operate or service the equipment. Local regulations may restrict the age of the operator.

Only adults and mature teenagers should operate a mower, and even mature teenagers should have adult supervision. Be sure a teenager:

1.has read and understands the Operator’s Manual and recognizes the risks involved;

2.is sufficiently mature to use caution; and

3.is of sufficient size and weight to operate the controls comfortably and to manage the mower without taking risks.

The owner/user can prevent and is responsible for accidents or injuries occurring to himself or herself, other people or property.

Preparation

Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use accessories and attachments approved by Exmark.

Wear appropriate clothing including safety glasses, substantial footwear, long trousers, and hearing protection. Do Not operate when barefoot or when wearing open sandals. Long hair, loose clothing or jewelry may get tangled in moving parts.
