Trimming (Fig.J, K)
With the trimmer on, angle it and swing side to side as shown 
in FigureJ.
Maintain a minimum distance of 610 mm between the guard 
and your feet as shown in FigureK.
 
WARNING: Keep the rotating string roughly 
parallel with the ground (tilted no more than 30°). This 
trimmer is not an edger. DO NOT TILT the trimmer so that 
the string is spinning near a right angle to the ground. 
Flying debris can cause seriousinjury.
Bump Feed Trimmer Line Feed
Your trimmer uses 2 mm diameter line that is spiral-shaped with 
smooth round edges. Cutting line will wear faster and require 
more feeding if the cutting is done along sidewalks or other 
abrasive surfaces or heavier weeds are beingcut.
As you use the trimmer, the string will get shorter due to wear. 
Gently bump the trimmer on the ground while running at 
normal speed and the line willfeed.
NOTE: Extending nylon line beyond the 381mm swath will 
negatively affect performance, runtime, and the life of the 
trimmer due to potential of damaging motor. Doing so may void 
thewarranty.
Helpful Cutting Tips (Fig.M)
•  Use the tip of the string to do the cutting; do not force string 
head into uncutgrass.
•  Wire and picket fences cause extra string wear, even 
breakage. Stone and brick walls, curbs, and wood may wear 
stringrapidly.
•  Do not allow spool cap
29 
 to drag on ground or 
othersurfaces.
•  In long growth, cut from the top down and do not exceed 
305 mmhigh.
•  Keep trimmer tilted toward the area being cut; this is the 
best cuttingarea.
•  The trimmer cuts when passing the unit from the left to 
right. This will avoid throwing debris at theoperator.
•  Avoid trees and shrubs. Tree bark, wood moldings, siding, 
and fence posts can easily be damaged by thestring.
