OPERATING INSTRUCTIONS It is recommended that the engine
not be operated longer than 1 min- ute at full throttle.
OPERATING POSITION
ALWAYS WEAR:
I i Eye protection
Longpant_
Heavy shoes
Cut from your left to your right.
z_ _WARNING: Always wear eye
protection. Never lean over the trimmer head. Rocks or debris can ricochet or
be thrown into eyes and face and cause blindness or other serious injury.
When operating unit, stand as shown and check for the following:
Wear eye protection and heavy clothing.
Hold trigger handle with right hand and assist handle with left hand.
Keep unit below waist level.
Cut only from your left to your right to ensure debris is thrown away from you. Without bending over, keep line
near and parallel to the ground and not crowded into material being cut.
Do not run the engine at a higher
speed than necessary. The cutting line will cut efficiently when the engine
is run at less than full throttle. At lower speeds, there is less engine noise and
vibration. The cutting line will last longer and will be less likely to "weld"
onto the spool. Always release the throttle trigger and
allow the engine to return to idle speed when not cutting.
J,
To stop engine:
Release the throttle trigger.
Push and hold the STOP switch in the STOP position until the engine
stops.
TWIST AND EDGE
The Twist and Edge feature allows for easy edging of sidewalks, patios,
driveways, etc.
1. Pull the tab toward the engine.
2. Twist the shaft to the edging posi- tion; release tab.
Tab
TRIMMER LINE ADVANCE The cutting head advances line au-
tomatically. Do not tap head on the ground to advance line. This may
break parts and cause cutting head to malfunction.
Upon unit start up, the line will advance
automatically to the correct cutting path
length.
Always keep the shield in place when the tool is being operated.
_&WARNING: Use only 0.080
inch (2 mm) diameter round line. Other sizes and shapes of line will not
advance properly and will result in im-
proper cutting head function or can
cause serious injury. Do not use other
materials such as wire, string, rope,
etc. Wire can break off during cutting and become a dangerous missile that can cause serious injury. CUTTING METHODS
_,WARNING: Use minimum speed and do not crowd the line when
cutting around hard objects (rock, gravel, fence posts, etc.), which can
damage the trimmer head, become entangled in the line, or be thrown
causing a serious hazard.
The tip of the line does the cutting.
You will achieve the best perform- ance and minimum line wear by not
crowding the line into the cutting area. The right and wrong ways are
shown below.
Tip of }ine does Line crowded into the cutting.
MOWING - Your trimmer is ideal for mowing in places conventional lawn
mowers cannot reach. In the mowing position, keep the line parallel to the
ground. Avoid pressing the head into the ground as this can scalp the ground and damage the tool.
Riqht '_/'roncl
The line will easily remove grass and weeds from around walls, fences, trees and flower beds, but it
also can cut the tender bark of trees or shrubs and scar fences. To help
avoid damage especially to delicate vegetation or trees with tender bark, shorten line to 4 - 5 inches (10 - 13 cm) and use at less than full throttle.
For trimming or scalping, use less than full throttle to increase line life
and decrease head wear, especially:
During light duty cutting.
Near objects around which the line
can wrap such as small posts,
trees or fence wire.
For mowing or sweeping, use full throttle for a good clean job.
TRIMMING - Hold the bottom of the trimmer head about 3 inches (8 cm)
above the ground and at an angle. Al- low only the tip of the line to make
contact. Do not force trimmer line into work area.
Trimming
(8 cm) above ground
SCALPING - The scalping technique removes unwanted vegetation down to
the ground. Hold the bottom of the trim- mer head about 3 inches (8 cm) above
the ground and at an angle. Allow the tip of the line to strike the ground
around trees, posts, monuments, etc. This technique increases line wear.
Scalping
Mowing
SWEEPING - The fanning action of the rotating line can be used for a quick and easy clean up. Keep the
line parallel to and above the surfaces
being swept and move the tool from side to side.
Sweeping
EDGING - Adjust trimmer to the edg-
ing position (see TWIST AND EDGE section). Allow only the tip of the line to make contact. Do not force trimmer
line into work area.
