Operating Technique: Hold the unit with both hands. Use a sweeping side-to-side motion, keeping the nozzle 2-3 inches above the ground. Work with the wind when possible for greater efficiency.
This engine uses a gasoline and 2-stroke oil mixture. Do not use straight gasoline or automotive oil.
WARNING! An improper fuel mixture will cause severe engine damage and is not covered under warranty. Never store the unit with fuel in the tank for more than 30 days.
Cold Start (Engine not warm):
Warm Start: Follow steps 1, 4, and 5 above. Do not use the choke or air purge.
