1.Press red STOP switch to the “I” ON position for start- ing (Figure 5-2A).

2.Pull the choke (A) out as far as it will go until the choke stays out. (Figure 5-2B). This advances the throttle so you do not have to hold trigger while starting.

After warm up - See the User's Manual section 5-2, step 7
