treated lumber.
Your risk of exposure to these chemicals
varies depending on how often you do this

OPERATION TIPS
WARNING
Always hold the
edger away from the body keeping clearance
between your body and the edger. Any
contact with the edger cutting head while
operating can result in serious personal injury.
• Hold the edger with your right hand on the
rear handle and your left hand on the front
handle.
• Keep a rm grip with both hands while in
operation.
• Edger should be held at a comfortable
position with the rear handle about hip
height.
• The edger will edge along sidewalks,
driveways, ower beds, curbs, and similar
areas.
• Cut at a steady pace. If the blade begins
to bog down, you are edging too fast; slow
your pace. Do not force the blade into the
ground.
• Light contact of the blade against the
sidewalk edge, curb, etc., is acceptable
and will not damage the edger.
• Best appearance is obtained when grass
is dry. Avoid edging in wet soil or wet grass
areas or the blade guard might clog and
result in an uneven edge. If the blade guard
becomes clogged, stop the edger, remove
the battery, and remove debris from the
blade guard.
