HOLDING THE TRIMMER

Before operating the unit, stand in the operating position (Fig. 8).
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 slightly bent,

the left hand holding the D-handle

• The unit is at waist level
• The trimmer attachment is parallel to

the ground and easily contacts the
grass without the need to bend over

TIPS FOR BEST TRIMMING RESULTS
• Keep the trimmer attachment parallel

to the ground.

• Cut from left to right whenever possible.

Cutting to the right improves the unit's
cutting efficiency. Clippings are thrown away from the operator.

• Trim only when grass and weeds are dry.
• The life of your cutting line is dependent upon:

- Following the trimming tips
- What vegetation is being cut
- Where vegetation is being cut

DECORATIVE TRIMMING
Decorative trimming is accomplished by
removing all vegetation around trees,
posts, fences and more. Rotate the
whole unit so that the trimmer
attachment is at a 30° angle to the ground (Fig. 9).

WARNING:

Always wear eye, hearing, foot and body

protection to reduce the risk of injury when operating this unit.

WARNING:

Before you begin using any attachment, read

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

CAUTION:

Before operating this unit, be sure that the

release button is fully snapped into the primary hole (Fig. 12),
and that the knob (Fig. 13) is securely tightened.

WARNING:

To avoid serious personal injury and

damage to the unit, shut the unit off before removing or
installing all attachments.
