without hesitation.
9. Once the engine is warmed up, place the blue choke lever
in Position 3 (Fig. 7). The unit is ready for use.
IF
... The engine hesitates, return choke lever to Position 2 (Fig. 7)
and continue warm up.
IF
... The engine does not start, go back to step 3.
IF

The engine fails to start after a few attempts, place the blue
choke lever in Position 3 and squeeze the throttle control. Pull the
starter rope briskly 3 to 8 times. The engine should start. If not, repeat.

OPERATING INSTRUCTIONS
HOLDING THE TRIMMER
Before operating the unit, stand in the operating position (Fig. 9).
Check for the following:
• The operator is
wearing eye
protection and proper
clothing
• With a slightly-bent
right arm, the
operator’s right hand is
holding the shaft grip
• The operator’s left arm is straight, the left hand holding the D-handle
• The unit is at waist level
• The cutting attachment is parallel to the ground and easily
contacts the grass without the need 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. 10) 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
WARNING:
Always wear eye, hearing, foot and body
protection to reduce the risk of injury when operating this
unit.

Each time the head is
bumped, about 1 inch
(25.4 mm) of trimming
line releases. A blade in
the cutting attachment
shield will cut the line to
the proper length if any
excess line is released.
For best results, tap the bump knob on bare ground or hard soil. If
you attempt a line release in tall grass, the engine may stall. Always
keep the trimming line fully extended. Line release becomes more
difficult when the cutting line gets shorter.
NOTE: Do not rest the Bump Head™ on the ground while the unit is
running.
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 posts

CAUTION:
Do not remove or alter the line cutting
blade assembly. Excessive line length will make the unit
overheat. This may lead to serious personal injury or
damage to the unit.
