Trimming / Brush cutting (Fig. N, O)

With the trimmer on, angle it and swing side to side as 
shown in figure N.
Maintain a minimum distance of 610 mm between the 
guard and your feet as shown in figure O.

 

WARNING: 

Keep the rotating string roughly parallel 

with the ground (tilted no more than 30 degrees). This 
trimmer is not an edger. DO NOT TILT the trimmer so 
that the string or brush cutter blade 

 16 

 is spinning 

near a right angle to the ground. Flying debris can 
cause serious injury.

Bump Feed Trimmer Line Feed

 

WARNING: 

To avoid personal injury, never bump the 

unit when the brush cutter assembly is attached to the 
motor housing.

Your trimmer uses 2.032 mm diameter nylon line. Cutting 
line will wear faster and require more feeding if the cutting 
is done along sidewalks or other abrasive surfaces or heavier 
weeds are being cut.
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 will feed.

NOTE: 

Extending nylon line beyond the 330 mm swath 

will negatively affect performance, runtime, and the life of 
the trimmer due to potential of damaging motor. Doing so 
may void the warranty.

Helpful Cutting Tips

•  Use the tip of the string to do the cutting; do not force 

string head into uncut grass.

•  Wire and picket fences cause extra string wear, even 

breakage. Stone and brick walls, curbs, and wood may 
wear string rapidly.

•  Do not allow spool cap to drag on ground or other surfaces.
•  In long growth, cut from the top down and do not 

exceed 304.8 mm high.

•  Keep trimmer tilted toward the area being cut; this is the 

best cutting area.

•  The trimmer cuts when passing the unit from the left to 

right. This will avoid throwing debris at the operator. 

•  Avoid trees and shrubs. Tree bark, wood moldings, siding, 

and fence posts can easily be damaged by the string.
