Operating Techniques – Nylon Line Head
Nylon line heads may be used for trimming, scything, edging, and scalping
of grass and light weeds.
Units with Speed Feed
®
line heads only: To advance trimmer line, tap
trimmer head against the ground while the head is turning at normal
operating speed.
Trimming
Feed the spinning line into the material to be cut. Tilt the line head to one
side to direct cutting debris away from you:
• SRM/DSRM/PAS/DPAS/SB/TX/C/T (Straight shaft, counter-clockwise line
head rotation) Models: Tilt the cutting head down on the right side while
cutting to direct cutting debris away from operator. Feed the line gradually
into the material you wish to cut, avoiding contact with fences or other
barriers.
• GT Models: Tilt cutting head to the left while cutting to direct debris away
from the operator.
Scything
Scything - Swing the cutting head in a level arc, gradually feeding the line
into the material being cut. Move forward with each arc to cut a swath.
Width of cutting swath depends on arc. Use a larger arc for a wider swath,
or a smaller arc for a narrow swath. Keep line head tilted to direct cutting
debris forward or away from you.
Edging and Scalping
Both of these are done with the nylon line cutting head tilted at a steep
angle. Scalping is removing top growth, leaving the earth bare. Edging is
trimming the grass back where it has spread over a pavement or driveway.
During both edging and scalping, hold the unit at a steep angle in a position
where the debris, and any dislodged dirt and stone, will not come back
towards you even if it ricochets off the hard surface.
General
• Debris flows in direction of line head rotation. Change line head position
to assure debris flow is directed away from operator.
• Keep cutting line away from wire fences to avoid entanglement.
• Operate trimmer only with cutting head below knee height.
