Installing the Cutting Attachment or Add-On
EZ-Link™ Coupler
NOTE: Place the unit on
the ground or on
a work bench to
make add-on
installation or
removal easier.
1. Turn knob
counterclockwise to
loosen (Fig. 14).
2. While firmly holding the
add-on, push it straight
into the EZ-Link™
coupler (Fig. 15).
Upper Shaft Housing
NOTE: Aligning the
release button
with the guide
recess will help installation (Fig. 14).
3. Turn the knob clockwise to tighten (Fig. 16).
CAUTION:
Lock the release button in the primary
hole and securely tighten the knob before operating this
unit.
90˚ Edging Hole
For edging (when using
(Trimmer Only)
the line head cutting
attachment with EZ-Link™
models), lock the release
button of the cutting
attachment into the 90°
edging hole (Fig. 16).
CAUTION:
Add-ons are to be used in the primary
hole only. Using the wrong hole could lead to personal
injury or damage to the unit.
HOLDING THE TRIMMER

• 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 assist 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. 18) while operating the trimmer at high speed.
WARNING:
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.
NOTE: Always keep the trimming line fully extended. Line release
becomes more
difficult as the
cutting line
becomes shorter.
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 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
TIPS FOR BEST TRIMMING RESULTS
• For best trimming results, operate unit at full throttle.
• Keep the cutting attachment parallel to the ground.
• Do not force the cutting attachment. Allow the tip of the line to
do the cutting, especially along walls. Cutting with more than the
tip will reduce cutting efficiency and may overload the engine.
• Cut grass over 8 inches (200 mm) by working from top to bottom
in small increments to avoid premature line wear or engine drag.
• Cutting from right to left improves the unit's cutting efficiency.
Clippings are thrown away from the operator.
• Slowly move the trimmer into and out of the cutting area at the
desired height. Move either in a forward-backward or side-to-
side motion. Cutting shorter lengths produces the best results.
• Trim only when grass and weeds are dry.
• The life of your cutting line is dependent upon proper adherence
of explained trimming techniques, what vegetation is cut, and
where vegetation is cut.
For example, the line will wear faster when trimming against a
foundation wall as opposed to trimming around a tree.
DECORATIVE TRIMMING
Decorative trimming is
accomplished by removing
all vegetation around trees,
posts, fences and more.
Rotate the whole unit so
that the cutting attachment
is at a 30° angle to the
ground (Fig. 19).
