SAFETY INFORMATION Do not operate or service the equipment before reading the entire manual. Safety precautions should be followed at all times when operating this equipment. Failure to read and understand the safety messages and operating instructions could result in injury to yourself and others. Potential hazards associated with the operation of this equipment will be referenced with hazard symbols which may appear throughout this manual in conjunction with safety messages.
SAFETY INFORMATION GENERAL SAFETY CAUTION NEVER operate this equipment without proper protective clothing, shatterproof glasses, respiratory protection, hearing protection, steel-toed boots and other protective devices required by the job or city and state regulations. Avoid wearing jewelry or loose fitting clothes that may snag on the controls or moving parts as this can cause serious injury. NEVER operate this equipment when not feeling well due to fatigue, illness or when under medication.
SAFETY INFORMATION TROWEL SAFETY NOTICE ALWAYS keep the machine in proper running condition. DANGER Engine fuel exhaust gases contain poisonous carbon monoxide. This gas is colorless and odorless, and can cause death if inhaled. The engine of this equipment requires an adequate free flow of cooling air. NEVER operate this equipment in any enclosed or narrow area where free flow of the air is restricted.
SAFETY INFORMATION NOTICE NEVER run engine without an air filter or with a dirty air filter. Severe engine damage may occur. Service air filter frequently to prevent engine malfunction. NEVER tamper with the factory settings of the engine or engine governor. Damage to the engine or equipment can result if operating in speed ranges above the maximum allowable. FUEL SAFETY DANGER BATTERY SAFETY DANGER DO NOT drop the battery. There is a possibility that the battery will explode.
SAFETY INFORMATION TRANSPORTING SAFETY CAUTION NEVER allow any person or animal to stand underneath the equipment while lifting. Ride-on trowels are very heavy and awkward to move around. Use proper heavy lifting procedures and DO NOT attempt to lift the trowel by the guard rings. NOTICE The easiest way to lift the trowel is to utilize the lift loops that are welded to the frame. These lift loops are located to the left and right sides of the operator’s seat.
SAFETY INFORMATION Trailer should be adjusted to a level position at all times when towing. Raise and lock trailer wheel stand in up position when towing. Place chock blocks underneath wheel to prevent rolling while parked. Place support blocks underneath the trailer’s bumper to prevent tipping while parked. Use the trailer’s swivel jack to adjust the trailer height to a level position while parked. ENVIRONMENTAL SAFETY NOTICE Dispose of hazardous waste properly.
