HOLDING THE TRIMMER
WARNING:
protection to reduce the risk of injury when operating this unit.
Before operating the unit, stand in the operating position (Fig. 8).
Check for the following:
• The operator is wearing eye
protection and proper clothing
• With a slightly-bent right arm, the
operator's hand is holding the shaft grip
• The operator's left arm is slightly bent,
the left hand holding the D-handle
• The unit is at waist level
• The trimmer attachment is parallel to
the ground and easily contacts the
grass without the need to bend over
TIPS FOR BEST TRIMMING RESULTS
• Keep the trimmer attachment parallel
to the ground.
• Cut from left to right whenever possible.
Cutting to the right improves the unit's
cutting efficiency. Clippings are thrown away from the operator.
• Trim only when grass and weeds are dry.
• The life of your cutting line is dependent upon:
- Following the trimming tips
- What vegetation is being cut
- Where vegetation is being cut
DECORATIVE TRIMMING
Decorative trimming is accomplished by
removing all vegetation around trees,
posts, fences and more. Rotate the
whole unit so that the trimmer
attachment is at a 30° angle to the ground (Fig. 9).
