Trimming Technique and Performance Notes
Tilt trimmer at a slight angle from the ground. Lower to grass or weeds you intend to cut. (If they are over 20cm (8") high, start cutting at top.) Slowly swing unit into and out of area being cut, holding the unit off the ground at desired cutting height. IMPORTANT— for the best cutting action against walls, fences and in high grass, move trimmer slowly so grass is cut WITH THE TIP of the high speed nylon line.
1. Avoid running trimmer with hub in contact with ground.
2. Trim only when grass and weeds are dry.
3. The life of your nylon line is dependent upon following the above trimming techniques, as well as what is being cut, and where the cutting is being done.
EXAMPLE: Line will wear faster when run against a foundation wall as compared to trimming around a tree. Some line breakage will occur from feeding unit too fast, from entanglement with foreign matter, from normal line fatigue, and from attempting to cut thick, stalky weeds in excess of unit’s capability.
Note: As the weather becomes cooler, the tendency for the nylon line to break becomes greater.
DO NOT USE UNIT WHEN TEMPERATURE IS BELOW 50° F
