OPERATING INSTRUCTIONS
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 motor.
• Cut grass over 8 inches (200 mm) by working from top
to bottom in small increments to avoid premature line
wear or motor 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 forwardbackward 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 previously explained
• What vegetation is 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. 10).
NOTE: Always keep the trimming line fully extended.
Line release becomes more difficult as cutting
line becomes shorter.
Each time the head is bumped, approximately 1 inch
(25.4 mm) of trimming line is released. A blade in the
string guard will cut the line if excess line is released.
For best results, tap the head on bare ground or hard
soil. If line release is attempted in tall grass, the motor
may overheat. Always keep the trimming line fully
extended. Line release becomes more difficult as the
cutting line becomes shorter.
Fig. 9
Bump Head
OPERATING THE TRIMMER
Clear the area to be cut before each use. Remove all
objects such as rocks, broken glass, nails, wire, or string
which can be thrown or become entangled in the cutting
attachment. Clear the area of children, bystanders, and
pets. At a minimum, keep all children, bystanders and
pets outside a 50 feet (15m) radius; there still may be a
risk to bystanders from thrown objects. Bystanders
should be encouraged to wear eye protection. If you are
approached, stop the motor and cutting attachment
immediately.
NOTE: Remove protective tape from the line cut-off
blade before operating trimmer.
ADJUSTING TRIMMING LINE LENGTH
The bump head allows the operator to release more
trimming line without stopping the motor. As line
becomes frayed or worn, additional line can be released
by lightly tapping the trimming head on the ground while
operating the trimmer (Fig. 9).
CAUTION:
Do not remove or alter the line
cutting blade assembly. Excessive line length will
make the unit overheat. This may lead to serious
personal injury or damage to the unit.
WARNING: Always wear eye, hearing, foot
and body protection to reduce the risk of
injury when operating this unit.
