Fuel WARNING • Gasoline is very flammable. Avoid smoking or bringing any flame or sparks near fuel. Make sure to stop the engine and allow it cool before refueling the unit. Select outdoor bare ground for fueling and move at least 3m(10ft) away from the fueling point before starting the engine. • The RedMax engines are lubricated by oil specially formulated for air-cooled 2-cycle gasoline engine use.
Operation ■ CONTROL ARM 1.Hold the upper end of the control arm in hand and, while pulling it away from the unit, rotate arm forward (anti-clockwise as the arrow direction) until it clicks. (The first position) ■ STARTING ENGINE IMPORTANT • Avoid operating the blower with the flexible tube and swivel joint disconnected. That will reduce the cooling air and the engine could be damaged by overheating. 1.Push the primer bulb until fuel flows out in the clear tube. 2.When the engine is cool, close the choke.
Operation the choke if it was set closed, and let the engine run at idle speed for a minute to warm it up. NOTE • When the engine fails to start after several attempts due to overchoking, open the choke and repeat pulling the rope. ■ ADJUSTING IDLE SPEED • The idling speed is set for 2000 rpm at the factory. If it is necessary to adjust the idle speed, use the adjustment screw on the top side of carburetor.
Maintenance WARNING • Make sure that the engine has stopped and is cool before performing any service to the blower. Contact with rotating blower fan or hot muffler may result in a personal injury. ■ AIR CLEANER • Never operate the blower without an air filter or with a deformed or broken filter element. • C h e c k the air cleaner every 25 hours of use or more frequently if used under dusty conditions. A clogged air filter may increase fuel consumption while cutting down the engine power.
Maintenance ■ MUFFLER WARNING • Inspect periodically, the muffler for loose fasteners, any damage or corrosion. If any sign of exhaust leakage is found, do not use the blower and have it repaired immediately. • Note that failing to do so may result in the engine catching on fire. ■ AIR INLET NET IMPORTANT • Blowing air is taken in from the air inlet net. When air flow has dropped down during operation, stop the engine and inspect the air inlet net for blocking by obstacles.
Maintenance ■ SHOULDER STRAP • If the shoulder strap is damaged it may break during use, thus causing the product to fall and resulting in personal injury. Follow the instructions below to replace the shoulder strap. • Pass the upper end of the strap through the hanger, making the FLAPPED SIDE OUTSIDE. • Put the end of the strap through the ring on the strap, and then push the ring toward the hanger as close as possible. WARNING • The flap on the end of the strap works as a stopper.
