OPERATION WARNING: Always shut off engine before fueling. Never add fuel to a machine with a running or hot engine. Move at least 30 ft. from refueling site before starting engine. Do not smoke! Failure to heed this warning could result in serious personal injury. OXYGENATED FUELS suddenly "thrust" the unit away from the object that was hit. This reaction can be violent enough to cause the operator to lose control of the unit. Blade thrust can occur without warning if the blade snags, stalls, or binds. This is more likely to occur in areas where it is difficult to see the material being cut. For cutting ease and safety, approach the weeds being cut with the brushcutter from the right to the left. In the event an unexpected object or woody stock is encountered, this practice could minimize the blade thrust reaction. DO NOT USE E85 FUEL. IT WILL VOID YOUR WARRANTY. WARNING: NOTE: Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates stated below are not covered under warranty. Extreme care must be taken when using blades to ensure safe operation. Read the safety information for safe operation when using a blade and refer to the safety rules and instructions in your attachment manual. Ethanol. Gasoline containing up to 10% ethanol by volume (commonly referred to as E10) or 15% ethanol by volume (commonly referred to as E15) are acceptable. E85 is not. STARTING AND STOPPING See Figures 6 - 8. OPERATING THE POWER HEAD See Figure 5. WARNING: Always position the unit on the operator's right side.

If it is not, continue to press the primer until you see fuel in the bulb. Set the choke lever to the FULL CHOKE position. WARNING: To avoid burns from hot surfaces, never operate unit with the bottom of the engine above waist level.

WARNING: Always hold the attachment away from the body keeping clearance between the body and the product. Any contact with the attachment cutting head can result in burns and/or other serious personal injury. BLADE THRUST Exercise extreme caution when using a blade attachment with this unit.
