During use:
•  Trim only when the grass and weeds are dry.
•  Do not trim grass at night. Always make sure you have 
adequate lighting.
•  Hold the grass trimmer/edger by both the switch handle 
and the auxiliary handle for best control and balance.
•  Stand with the cutting head tipped down at an angle in 
front, guiding the grass trimmer/edger in a semicircular 
motion around you.
•  If possible, guide the grass trimmer/edger to the left to 
cut. The line will cut as soon as it leaves the guard, and 
the clippings are thrown away from you.
•  To produce a smoothly trimmed area, move the grass 
trimmer/edger out of the area being cut with consistent 
speed and height.
•  Use only the tip of the cutting line to do the trimming, 
especially near walls and fences. Trimming with the side 
of the cutting line may overload the motor, wear out the 
line faster, and break the line more often.
•  Do not rest the trimmer spool on the ground while trimming. This will cause spool wear and battery 
drain.
•  If the grass is higher than 6 in. (15 cm), trim in small stages.
•  When the grass trimmer/edger is turned off and the spool stops rotating, the cutting line will relax 
and may recede. Feed extra cutting line before storing the trimmer to prevent losing the line 
completely into the spool.
•  If the diameter of the cutting area gets smaller, the line is worn down and needs to be advanced 
more often.
•  If the grass trimmer/edger is not cutting correctly, the cutting line may not be feeding properly. 
Remove and rewind the line spool.
