Do not use waste or regenerated oil that can cause damage to the oil pump. NOTE NOTE ¦ STARTING ENGINE The cutting head will start rotating upon the engine starts. 1. Feed fuel and chain oil into their respective tanks and tighten the caps securely. (OP1) 2. 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. 3. Push the primer pump several times until overflown fuel flows out in the clear tube. (OP2) 4. Move the choke lever to the closed position. (OP3) 5. Set the ignition switch to the “start” position. While pulling the throttle lever, push the set button, and release the throttle, then the throttle lever is in to the “start” position. (OP4) 6. While holding the unit firmly, pull out the starter rope quickly until engine fires.

Such actions can cause starter failures. 7. Move the choke lever downward to open the choke. And restart engine. (OP3) 8. Allow the engine to warm up for a several minutes before starting operation. 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. NOTE IMPORTANT WARNING 8.

Maintenance .025 in 0.655mm MA12 ¦ SPARK PLUG • Starting failure and mis-firing are often caused by a fouled spark plug. Clean the spark plug and check that the plug gap is in the correct range. For a replacement plug, use the correct type specified by RedMax. (MA12) • REPLACEMENT PLUG IS A NGK CMR7A. IMPORTANT • Note that using any spark plug other than those designated may result in the engine failing to operate properly or in the engine becoming overheated and damaged. • To install the spark plug, first turn the plug until it is finger tight, then tighten it a quarter turn more with a socket wrench. 87~104 in-lbs TIGHTENING TORQUE: (9.8~11.8 N.m.) ¦ MUFFLER WARNING (1) MA13 • Inspect periodically, the muffler for loose fasteners, any damage or corrosion.
