Be sure all safety devices are in working order and warning labels are in place, these items are installed for your safety. Know how to stop the engine and attachments quickly in case of emergency. Understand the use of all controls.
Fire and Burn Hazard . Gasoline is extremely flammable, and gasoline vapor can explode. Use extreme care when handling gasoline. Keep gasoline out of reach of children. l Refuel in a well ventilated area with the engine stopped. l Allowed the engine to cool before refueling. Fuel vapor or spilled fuel may ignite. l The accumulation of dry grass and leaves around the engine, the exhaust system, or on top of the cutter deck (especially around the pulleys) may ignite.
Thrown Object Hazard Objects hit by the blades can be thrown from the tractor with great force, and may cause serious injury. l Before mowing, clear the mowing area of sticks, stones, dog bones, and other litter and loose objects. Mow only in daylight, or in well-lit areas at night, so you can see and avoid objects in the grass. l Before operating the tractor, be sure the side discharge guard is down, or that the optional grass catcher bags and discharge chute are in place.
l l To avoid injury to yourself and others, before leaving the Tractor unattended, ALWAYS, - park on level ground. - disengage the power take-off. - lower the attachment(s). - Lock the parking brake. - stop the engine. - and remove the key. Be sure to follow the instructions below whenever applying the differential lock. - Be sure that the main transmission lever is set in 4th gear or lower, and reduce engine speed before applying the differential lock. - Do not apply while turning the tractor.
MAINTENANCE l l l l l l l SAFETY Before performing maintenance/inspection, read the instructions thoroughly. Before cleaning, inspecting or servicing the tractor, be sure to - Turn off and lower any attachments. - Stop the engine and remove the key. - Remove the spark plug caps.
