1. DANGER This blower uses a four cycle gasoline engine with lubricating oil contained in its crankcase Do not operate the engine unless proper oil level is maintained Failure to operate the engine without the proper crankcase oil level will result in severe engine damage and the possibility of property damage and or personal injury If improperly filled the engine may emit excessive smoke when operated or appear to be seized when attempting to start To correct these situations drain the excess oil and remove the engine spark plug to clear oil trapped above the piston FUELING CAUTIONS Gasoline is flammable Use extreme caution when handling gasoline or mixing fuel Always use UL approved containers for the fuel storage and or transportation of fuel Do not smoke operate spark inducing equipment nearby or bring any fire or flame near the fuel Always shut off the engine and allow it to cool before refueling Never remove the gasoline tank filler cap while the engine is running Never operate an engine without a gasoline tank filler cap Select bare ground for refueling and move at least 10 feet from the fueling spot before starting the engine Wipe off any spilled fuel before starting the engine and check for leakage If a fuel or oil leak is found do not start or run the engine until the leak is fixed and the spillage has been wiped away 10 Take care not to get fuel or oil on your clothi2. Start up 1 Connect air supply line to air motor 2 Turn on air supply valve on motor 3 Regulate the air pressure to 40 psi and 30 CFM a Any variation of that will affect the performance of the air motor and pump Shut down Shut down air supply to air motor Slowly bleed off any excess air pressure and close valve Disconnect supply airline Blow dry clean air through motor at a low pressure to rid the motor of any damaging moisture eS Storage 1 If motor is to be stored a Disassemble plumbing from inlet port b Add a few drops of oil to the inlet port c Manually rotate shaft to circulate the oil GASOLINE POWERED BLOWER 9505 amp 9505 50 Filling the Engine Crankcase with Oil Tools required e Small clean funnel e Aclean shop rag e Oil 1 Position the blower on level ground 2 Wipe away any dust or dirt from the engine crankcase on the end opposite to the gasoline tank Remove the filler plug 3 Using the funnel pour 2 3 qt or 21 ounces if required of high grade 30W motor oil into the engine crankcase DO NOT OVERFILL Refer to the operation and maintenance instructions supplied by the engine manufacturer for specific information regarding proper oil type weight and engine service classification 4 Reinstall the engine crankcase filler plug Wipe off any excess oil spilled on engine 5 Do not mix oil with the gasoline The air filter element is the paper type and does not require oiling
3. 1 Place the blower on level ground on the desired work location a Ensure motor is filled with the recommended oil and oil level is maintained b The location should be relatively flat to prevent vibration from allowing the blower tc move 2 Open the fuel feed valve 3 When starting a cold engine move the choke lever to the CLOSED position or as far as possible in the direction indicated by the arrow on the lever a Awarm engine may not require choking 4 Pull the throttle control lever to the RUN position or 2 3 of the way to the FAST position 5 Turn the engine switch to the ON position 6 Position the recoil starter handle until resistance is felt a Pull briskly and return starter grip gently b If the engine fires but does not start do not continue to choke the engine c Repeat until the engine starts d When the engine starts open the control gradually 11 7 Select an adequate clearance for the operator s arm and or hand when starting the engine a A small or confined work area for starting the engine can result in personal injury 8 Operate the blower at proper governed engine RPM or at the speed that delivers the required air flow rate 9 To stop the blower move the throttle control lever to the STOP position or by grounding the spark plug with the lever provided if so equipped DANGER Operation of the blower on any given surface material and or configuration may generate random movem
