LINE TRIMMINg CUT-Off bLADE
See Figure 5.
The trimmer is equipped with a line trimming cut-off blade
on the grass deflector. Replace the string whenever you hear
the engine running faster than normal, or when trimming ef-
ficiency diminishes. This will maintain best performance.
OPERATINg ThE TRIMMER
See Figure 6.
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.
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.
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, dis-
connect the spark plug wire, and remove the grass.
NOTE: Always operate at full throttle. 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.
OPERATION
CUTTINg TIPS
See Figures 6 - 7.

Avoid hot surfaces by always keeping the tool away
from your body. (Proper operating position shown in
figure 6.)
 Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
 The trimmer cuts when passing the unit from right to left.
This will avoid throwing debris at the operator. Avoid cut-
ting in the dangerous area shown in figure 7.
 Use the tip of string to do the cutting; do not force string
head into uncut grass.
 Wire and picket fences cause extra string wear and break-
age. Stone and brick walls, curbs, and wood may wear
string rapidly.
 Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the string.
