OPERATION

OPERATING YOUR TRIMMER
Before operating the unit, stand in the operating posi -
tion (Fig. 15). Check for the following:
• The operator is wearing eye protection and proper
clothing.
• With a slightly-bent right arm, the operator' s right
hand is holding the shaft grip.
• The operator' s left arm is straight, the left hand hold -
ing the handle.
• The unit is at waist level.
• The cutting attachment is parallel to the ground and
easily contacts the grass without the need to bend over.
ADVANCING THE CUTTING LINE
String advance is controlled by tapping the string head
on grass while running engine at full throttle.
1. Run engine at full throttle.
2. Tap the knob on ground to advance string. The string
advances each time the knob is tapped. Do not hold
the knob on the ground.
TIPS FOR BEST TRIMMING RESULTS
• For best trimming results, operate unit at full throttle.
• 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 ef -
ficiency and may overload the engine.
• Cut grass over 8 inches (200 mm) by working from
top to bottom in small increments to avoid prema -
ture line wear or engine drag.
• Slowly move the trimmer into and out of the cutting
area at the desired height. Move either in a forward-
backward 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:
1. Proper adherence to explained trimming techniques
2. What vegetation is cut
3. Where vegetation is cut
For example, the line will wear faster when trimming
against a foundation wall as opposed to trimming
around a tree.
Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick, stalky weeds
• Forcing the line into objects such as walls or fence posts

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-degree angle to the ground (Fig. 16).
