Always stand clear of discharge area. Do not direct discharge toward other people. OL1805 OL1810 Keep people away from unit while operating. Never carry children. OL1806 OL18111 Shut off engine, remove key, and read manual before you adjust or repair unit. 10 OL1812 NO STEP! Always keep feet away from rotating parts. • If machine stops going uphill, stop blade and back down slowly. • Avoid sudden turns. • Keep safety devices (guards, shields, switches, etc.) in place and working.
8. DANGER! Keep hands and feet away. Do not operate mower unless guards are in operating position or bagger is attached. EMISSION CONTROL SYSTEM CERTIFICATION LABEL Tampering with emission controls and components by unauthorized personnel may result in severe fines or penalties. Emission controls and components can only be adjusted by EPA and/or CARB authorized service centers. Contact your Ariens Equipment Retailer concerning emission controls and component questions.
NEVER direct discharge towards persons or property. Thrown objects may ricochet back towards operator. ALWAYS stand clear of the discharge area. ALWAYS disengage attachment, stop unit and engine, remove key, engage parking brake, and allow moving parts to stop before leaving operator’s position. Use extreme caution on gravel surfaces. Disengage PTO when attachment is not in use and when crossing gravel surfaces. DO NOT operate unit if safety interlock system is damaged or disabled.
NEVER fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling. When practical, remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle.
ASSEMBLY Check Tire Pressure WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. CAUTION: Avoid injury! Explosive separation of tire and rim parts is possible when they are serviced incorrectly: • Do not attempt to mount a tire without the proper equipment and experience to perform the job. • Do not inflate the tires above the recommended pressure. • Do not weld or heat a wheel and tire assembly. Heat can cause an increase in air pressure resulting in an explosion.
