5. For safe operation ■ BEFORE STARTING THE ENGINE 1. The area within a perimeter of 50 feet (15m) of the person using the product should be considered a hazardous area into which no one should enter. If necessary yellow warning rope, warning signs should be placed around the perimeter of the area.
5. For safe operation WARNING Never place the throttle into the high speed position when starting the engine. 3. After starting the engine, check to make sure that the cutting attachment stops rotating when the throttle is moved fully back to its original position. If it continues to rotate even after the throttle has been moved fully back, turn off the engine and take the unit to your authorized Red Max servicing dealer for repair.
5. For safe operation • IF SOMEONE COMES 1. Guard against hazardous situations at all times. Warn adults to keep pets and children away from the area. Be careful if you are approached. Injury may result from flying debris. 2. If someone calls out or otherwise interrupts you while working, always be sure to turn off the engine before turning around. ■ MAINTENANCE 1.
5. For safe operation ■ HANDLING FUEL 1. The engine of the RedMax product is designed to run on a mixed fuel which contains highly flammable gasoline. Never store cans of fuel or refill the tank of the unit in any place where there is a boiler, stove, wood fire, electrical sparks, welding sparks, or any other source of heat or fire which might ignite the fuel. 2. Never smoke while operating the unit or refilling its fuel tank. 3. When refilling the tank, always turn off the engine and allow it to cool down.
6. 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.
6. Fuel again for at least one minute. As some oils may be difficult to agitate depending on oil ingredients, sufficient agitation is necessary for the engine to last long. Be careful that, if the agitation is insufficient, there is an increased danger of early piston seizing due to abnormally lean mixture. 5. Put a clear indication on the outside of the container to avoid mixing up with gasoline or other containers. 6. Indicate the contents on outside of container for easy identification.
7. Operation ■ STARTING ENGINE OP1 WARNING (1) The cutting head will start rotating upon the engine starts. OP2 (2) (4) OP3 (5) (3) 1. Rest the unit on a flat, firm place. Keep the cutting head off the ground and clear of surrounding objects as it will start rotating upon starting of the engine. 2. Push the primer pump several times until overflown fuel flows out in the clear tube. (OP1) 3. Move the choke lever to the closed position. (OP2) 4. Set the ignition switch to the “START” position.
7. Operation NOTE 1. When restarting the engine immediately after stopping it, leave the choke open. 2. Overchoking can make the engine hard to start due to excess fuel. When the engine failed to start after several attempts, open the choke and repeat pulling the rope, or remove the spark plug and dry it. ■ STOPPING ENGINE (OP3) 1. Release the throttle lever and run the engine for a half minute. 2. Shift the ignition switch to the “STOP” position.
