OPERATING THE TRIMMER
See Figure 10.
WARNING:
Engine housing may become hot during trimmer opera-
tion. Do not rest or place your arm, hand, or any body
part against the engine housing during trimmer operation.
Only hold the trimmer as shown in Figure 10 with all body
parts clear of engine housing. Extended contact with the
engine housing can result in burns or other injuries.
WARNING:
Always position the unit on the operator's right side. The
use of the unit on the operator's left side will expose the
user to hot surfaces and can result in possible burn injury.
WARNING:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.

OPERATION
9 — English
Hold the trimmer with your right hand on the rear handle
and your left hand on the front handle. Keep a firm grip with
both hands while in operation. Trimmer should be held at a
comfortable position with the rear handle about hip height.
Always operate trimmer in RUN position. Cut tall grass
from the top down. This will prevent grass from wrapping
around the shaft housing and string head which could cause
damage from overheating. If grass becomes wrapped around
the string head, STOP THE ENGINE, disconnect the spark
plug wire, and remove the grass. Prolonged cutting at partial
throttle will result in lubricant dripping from the muffler.
WARNING:
Always hold the string trimmer away from the body keep-
ing clearance between the body and the product. Any
contact with the housing or string trimmer cutting head
can result in burns and/or other serious personal injury.
CUTTING TIPS
See Figures 10 - 12.
 Avoid hot surfaces by always keeping the tool away from
your body. (Proper operating position shown in figure 10.)
 Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
 The curved shaft trimmer cuts when passing the unit from
right to left. The straight shaft trimmer cuts when passing
the unit from left to right. This will avoid throwing debris at
the operator. Avoid cutting in the dangerous area shown
in illustration.
 Use the tip of line to do the cutting; do not force string
head into uncut grass.
 Wire and picket fences cause extra line wear, even
breakage. Stone and brick walls, curbs, and wood may
wear line rapidly.
 Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the line.
ADVANCING STRING USING THE REEL-EASY
TAP ADVANCE SYSTEM
String advance is controlled by tapping the string head's
spool retainer on grass while running engine at full throttle.
 Run engine at full throttle.
 Tap string head on ground to advance string. String
advances each time the head is tapped.
 Several taps may be required until string strikes the cut
off blade.
 Resume trimming.
NOTE: If the string is worn too short you may not be able to
advance the string by tapping it on the ground. If so, STOP
THE ENGINE, disconnect the spark plug wire, and manually
advance the string.
