Each time the head is bumped, about 1 inch (25.4 mm.)

of trimming line is released. A blade in the cutting

attachment shield will cut the line to the proper length if

excess line is released.

For best results, tap the Bump Head™ on bare ground

or hard soil. If line release is attempted in tall grass, the

engine may stall. Always keep the trimming line fully

extended. Line release becomes more difficult as the

cutting line becomes shorter.

NOTE: Do not rest the Bump Head™ on the ground

while operating.

CAUTION: Do not remove or alter the line

cutting blade assembly. Excessive line length

will make the clutch overheat. This may lead

to serious personal injury or damage to the

unit.

Some line breakage will occur from:

• Entanglement with foreign matter

• Normal line fatigue

• Attempting to cut thick, stalky weeds

• Forcing the line into objects such as walls or fence

HOLDING THE TRIMMER

WARNING: Always wear eye, hearing, foot

and body protection to reduce the risk of

injury when operating this unit.

Before operating the unit, stand in the operating position

(Fig. 7). Check for the following:

• The operator is wearing eye protection and proper

clothing.

• The right arm is slightly bent, and the hand is holding

the shaft grip.

• The left arm is straight, and the hand is holding the

handle.

• The unit is below waist level.

• The cutting attachment is parallel to the ground and

easily contacts the vegitation to be cut without the

operator having to bend over.

ADJUSTING TRIMMING LINE LENGTH

The Bump Head™ cutting attachment allows you to

release trimming line without stopping the engine. To

release more line, lightly tap the cutting attachment on

the ground (Fig. 9) while operating the trimmer at high

speed.

NOTE: Always keep the trimming line fully extended.

Line release becomes more difficult as cutting

line becomes shorter
