Do you know how the General Trimmer Head Maintenance?

The most common cause of trimmer head malfunction is poor mainte-nance, especially true for tap-for-line, bump-feed, and fully automatic heads. Customers buy these heads for convenience so they don’t have to reach down and advance the line–yet that added convenience often means the head is not properly maintained. A Few Tips Clean the head thoroughly each time line is refilled. Wipe all grass and debris from internal parts. Water will dissolve accumulated buildup, but a cleaner such as 409 will aid in the task. Replace worn eyelets. Never run a trimmer head without eyelets in-stalled. Running with an eyelet missing will cause the trimmer line to wear into the body of the head as well as create excessive vibration. Replace any noticeably worn parts. A knob at the bottom of a head is a wear part if it contacts the ground, especially in abrasive soil conditions and when the head is run against sidewalks and curbs. When winding line, keep both strings separate. Try to wind as evenly as possible to prevent snarling and reduce vibration. Trim line ends to equal length from the eyelet. Operation with uneven length trimmer line will cause excessive vibration. Always replace worn or damaged parts promptly. Make sure line is wound in the correct direction for the rotation of the head–For heads with a LH arbor bolt,

wind line counterclockwise as viewed from the knob at the end of the trimmer head. For heads with a RH arbor bolt, wind line clockwise as viewed from the knob. ”Clockwise for RH, Counterclockwise for LH” Any plastic material can dry out, especially when stored at high tem- perature and when exposed to direct sunlight. To prevent this, Shindaiwa packages much of their trimmer line in all-plastic holders so the line can be soaked in water to restore moisture. Trimmer line with very low moisture content is brittle and inflexible. Wind-ing dry line on a trimmer head can be very difficult. After soaking in water, the same line will become very flexible and far tougher, and service life will be significantly extended. NOTE: This also applies to flail blades. CAUTION: Remove the bearing or bushing from from Super Flail blades before soaking in water.
