OPERATION

OPERATING TIPS

Clear the area to be cut before each use. Remove
all objects such as rocks, broken glass, nails, wire,
or string which can be thrown or become entangled
in the string head.

Keep the string trimmer tilted toward the area being
cut. Avoid digging into grass.

Slowly move the string trimmer in and out of the
area being cut.

Use the tip of line to do the cutting - do not force
string head into uncut grass.

Cut tall grass from the top down. This will prevent
grass from wrapping around the string head that
may cause damage from overheating.  If grass or
other debris becomes wrapped around the string
head, STOP THE MOTOR by releasing the trigger
and allow the string head to stop spinning. Remove
the battery pack and then remove the grass or
debris.

CUTTING LINE

This string trimmer is equipped with a string cut off
blade on the grass shield. 

See Figure 11. For best

cutting, advance line until it is trimmed to length by the
string cut-off blade. Advance line whenever you hear
the motor running faster than normal. This will main-
tain best performance and keep the cutting line long
enough to advance properly.

CUT OFF BLADE

Avoid using solvents when cleaning plastic parts.
Most plastics are susceptible to damage from various
types of commercial solvents and may be damaged
by their use. Use a clean cloth to remove dirt, oil,
grease, etc.

  WARNING:

When servicing use only identical Homelite replace-
ment parts. Use of any other parts can create a
hazard or cause product damage.

Wire and picket fences cause extra line wear,
even breakage.   Stone and brick walls, curbs, and
wood may wear line rapidly. Walk around trees
and shrubs. Tree bark, wood moldings, siding, and
fence posts can easily be damaged by the line.

Keep the string trimmer tilted toward the area being
cut. To trim around trees, posts, fences, etc., keep
the string trimmer at a 30-degree angle.

Figure 12.
