TIPS FOR BEST RESULTS
• To direct clippings away from the operator, tilt the cutting head
slightly down to the left; cut from right to left whenever possible.
• Do not trim wet grass or weeds.
NOTE: Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick vegetation
• Forcing the line into objects such as walls or fence posts
• Remove the battery from the unit when it is not in use.
DECORATIVE TRIMMING
When trimming around trees, posts, fences, etc., rotate the whole
unit so that the cutting head is at a 30° angle to the ground (Fig. 16).
EDGING
Rotating the Lower End of the Unit
WARNING:
To avoid serious personal injury and
damage to the unit, turn the unit off and remove the
battery before rotating the lower end.
WARNING:
Keep the cutting head shield positioned to
deflect debris away from the operator. Small objects can
be propelled at high speed, causing injury.
When edging around sidewalks, flowerbeds, etc., rotate the lower
end of the unit 90° (Fig. 17).
1. Pull the boom mount away from the locking collar (Fig. 18).
2. Rotate the lower end of the unit counterclockwise 90° (Fig. 18).
3. Release the boom mount.
4. Make sure the lower end of the unit is securely locked in place.
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.
