Safety

CAUTION

This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.

Wear hearing protection when operating this machine.

Inspect the area where the equipment is to be used and remove all rocks, toys, sticks, wires, bones, and other foreign objects which can be thrown by the machine and may cause personal injury to the operator or bystanders.

DANGER

LPG fuel is extremely flammable and vapors are explosive.

A fire or explosion from LPG fuel can burn you, others, and cause property damage.

Never smoke around tank(s) and stay away from an open flame or where fumes may be ignited by a spark.

Extinguish all sources of spark or flame when approaching LPG tanks or mowers. The hazard increases for enclosed trailers or storage locations where vapor leakage may occur and collect.

LPG is heavier than air and may accumulate in low lying areas, such as ditches, drains, or pits.

LPG tank(s) should be filled by trained and qualified personnel ONLY.

Never tamper with or repair the tank(s); contact trained and qualified personnel.

Do Not change the tank(s) when the engine is running.

Before disconnecting the hose(s), purge all LPG vapors from the system, by closing the fuel valve(s) on ALL tanks and allowing the engine to run until it stops.

Store the tank(s) away from heat, sparks, or open flames.

Do Not operate without entire exhaust system in place and in proper working condition.
