1.

Turn knob counterclockwise to loosen (Fig. 8).

2.

While firmly holding the add-on, push it straight into the EZ-
Link™ coupler (Fig. 9).

NOTE:

Aligning the release button with the guide recess will help
installation (Fig. 8).

3.

Turn the knob
clockwise to tighten
(Fig. 10).

For decorative
trimming/edging with the

line head cutting
attachment

, lock the

release button of the
cutting attachment into
the 90° hole  (Fig. 10).

WARNING:

Before you begin using any attachment, read and understand the manual

that came with the attachment.  Follow all safety information contained within.

HOLDING THE TRIMMER

Before operating the unit, stand in the operating position (Fig. 11).
Check for the following:

The operator is wearing eye protection and proper clothing

With a slightly-bent right arm, the operator’s 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. 12) while
operating the trimmer at high speed.

NOTE:

Always keep the trimming line fully extended. Line release
becomes more difficult when the cutting line gets shorter.

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

TIPS FOR BEST TRIMMING RESULTS

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.

Cut from right to left whenever possible. Cutting to the 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:

Following the trimming techniques

What vegetation is being cut

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. 13).

WARNING:

Always wear eye, hearing, foot and body protection to reduce the risk of

injury when operating this unit.

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.
