Each time the head is bumped, about 1 inch (25.4 mm) of trimming line is released. A blade in the cutting attachment shield will cut the line to the proper length if excess line is released.
For best results, tap the Bump Head™ on bare ground or hard soil. If line release is attempted in tall grass, the engine may stall. Always keep the trimming line fully extended. Line release becomes more difficult as the

NOTE: Do not rest the Bump Head™ on the ground while the unit is running. 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 |
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 efficiency and may overload the engine. |
• | Cut grass over 8 inches (200 mm) by working from top to bottom in small |
| increments to avoid premature line wear or engine drag. |
• | Cutting from right to 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 |
| shorter lengths produces the best results. |
• | Trim only when grass and weeds are dry. |
CAUTION: Lock the release button in the primary hole and securely tighten the knob before operating this unit.
• The life of your cutting line is dependent upon proper adherence of |
explained trimming techniques, what vegetation is cut, and where |
vegetation is cut. |

• The cutting attachment is parallel to the ground and easily contacts the grass without the need to bend over
For example, the line will wear faster when trimming against a foundation wall as opposed to trimming around a tree.
DECORATIVE TRIMMINGDecorative 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. 15).
