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 return tube. (OP1)

3. Move the choke lever to the closed position.

(OP2)

4. Set the ignition switch to the “start” position.

(OP3)

5. While holding the unit firmly, pull out the starter

rope quickly until engine fires. (OP4)

• Avoid pulling the rope to its end or returning it by

releasing the knob. Such actions can cause
starter failures.

6. Move the choke lever to the open position

(OP2). And pull out the starter rope quickly to
restart engine. (OP4)

7. Allow the engine to warm up for several minutes

before starting operation.

1. When restarting the engine immediately after

stopping it, leave the choke open (OP2) and
push the primer pump several times (OP4). 

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.
