My trimmer vibrates excessively and it never did this before. What can I do to help the situation?
Most likely the trimmer head needs to be cleaned and the line in the spool rewound to ensure optimum balance. Also, keeping the line cutter on the debris shield sharp enough to make a clean cut will ensure equal lengths for a balanced operation. See your dealer if the problem persists.
How do I choose the proper trimmer line for my grass trimmer?
Trimmer line should be chosen by matching its diameter to the horsepower of the unit. The larger the line, the greater the power needed to rotate it.
Word of CAUTION! Failure to match the cutting-line diameter with horsepower may cause mechanical problems such as excessive carbon build-up, spark arrestor clogging, premature clutch failure, or overheating.
The following may be used as a general guide to line selection according to diameter.

What is the proper cutting-line length for my grass trimmer?
To adjust the proper cutting-line length for your grass trimmer, pull the line out of the head and stretch it across the bottom of the head. The ends of the line should overlap 1 to 2 inches.
CAUTION! If more cutting line is used than recommended, mechanical problems such as carbon build-up, spark arrestor clogging, premature clutch failure, or overheating may result.
The line on my trimmer breaks so easily that I continually have to stop and index the string. Is it just me or what's wrong?
Occasional users may experience this problem more than commercial operators simply because of infrequent use, but there are several things that can be done to improve the situation. When operating a string trimmer along wire fences or concrete slabs it is important not to allow the string to make contact with these types of hard surfaces.
Slowing down the travel rate of the trimmer (not engine rpm’s) and allowing the string to actually cut the grass also helps. By keeping the string submerged in water until it will actually be used in a trimmer head helps maintain the moisture content and prevents brittleness.
I've followed the instructions in the manual on how to disassemble the trimmer head and it just will not come apart.
Sometimes while cutting wet grass the residue or build up that results may collect between two different parts and cause them to stick together when it dries. If this occurs try soaking the trimmer head in water, then make another attempt to disassemble the unit.
