EDGING (AS A TRIMMER)
The trimmer attachment can be used for edging (Fig. 25). Alternatively,
a bladed lawn edger attachment can also be purchased for use with
this unit.
Rotating the Trimmer Attachment
WARNING:
To avoid serious personal injury and
damage to the unit, shut the unit off before rotating the
attachment.
When edging around sidewalks, flowerbeds, etc., rotate the trimmer
attachment 90° inside the coupler. DO NOT rotate the entire unit 90°.
1. Turn the knob counterclockwise to loosen the coupler (Fig. 26).
2. Press and hold the release button (Fig. 26).
3. Rotate the attachment until the release button snaps firmly into
the 90° edging hole (Fig. 26).
4. Turn the knob clockwise to tighten the coupler (Fig. 26).
WARNING:
Only snap the release button into the 90°
edging hole when edging with the trimmer attachment.
Using the 90° edging hole with other attachments could
lead to personal injury or damage to the unit.
Maintaining the Trimming Line
Hard surfaces, such as sidewalks, can cause the trimming line to
wear down quickly or break.
• Frequently check and adjust the trimming line length. Refer to
Adjusting the Trimming Line Length. Always keep the trimming
line fully extended.
• DO NOT force the unit. Make shallow cuts in as many passes as are
necessary to achieve the desired depth. Cut at a slow, even pace.
WARNING:
To avoid serious personal injury, always stop
the engine and allow it to cool before cleaning or maintaining
the unit. Never perform cleaning or maintenance while the
unit is running. Disconnect the spark plug wire to prevent
the unit from starting accidentally.
WARNING:
Wear protective clothing and observe all
safety instructions to prevent serious personal injury.
