Maintenance - Surtek DG730R Manual De Usuario

Hold the trimmer with the right hand on the
rear handle and the left hand on the front "D"
handle. Keep a firm grip with both hands while
in operation. Trimmer should be held at a com-
fortable position with the rear handle about
hip height.
Always operate trimmer at
full throttle. Cut tall grass
from the top down. This will
prevent grass from wrapping
around the driveshaft hous-
ing and string head which
may cause damage from
overheating. If grass be-
comes wrapped around the
string head, stop the engine, disconnect the
spark plug wire, and remove the grass. Pro-
longed cutting at partial throttle will result in
oil dripping from the muffler.
ADVANCING THE STRING
String advance is controlled
by tapping string head on
grass while running engine
at full throttle.
1. Run engine at full throt-
tle.
2. Tap string head on ground to advance string.
String advances each time the head is tapped.
3. Several taps may be required until string
strikes the cut off blade.
4. 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, and
manually advance the string.
CUTTING TIPS
• Keep the trimmer tilted toward the area be-
ing cut; the section closest to the ground is the
best cutting area.
• Do not cut in dangerous cutting area.
• 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, even breakage. 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.

GRASS DEFLECTOR LINE TRIMMING CUTOFF
BLADE
This trimmer is equipped with a line trimming
cut-off blade on the grass deflector.
For best cutting, advance string until it is
trimmed to length by the cut-off blade. Ad-
vance string whenever you hear the engine
running faster than normal.
This will maintain best performance and keep
string long enough to advance properly.

MAINTENANCE

IMPORTANT: BEFORE USING THE TRIM-
MER, CARRY OUT REGULAR MAINTENANCE
OR CHANGING ACCESSORIES, READ THE "PE-
RIODIC MAINTENANCE CHART" ON PAGE 16.
WARNING: Use only original manufac-
turer's replacement parts, accessories and at-
tachments. Failure to do so can cause possible
injury, poor performance and may void your
warranty.
• You may make adjustments and repairs de-
scribed here. For other repairs, have the trim-
mer serviced by an authorized service dealer.
• Consequences of improper maintenance may
include excess carbon deposits resulting in loss
of performance and discharge of black oily
residue dripping from the muffler.
• Make sure all guards, straps, deflectors and
handles are properly and securely attached to
avoid the risk of personal injury.
REPLACING THE NYLON THREAD
1. Hold the string head and
unscrew the spool retainer.
Turn counterclockwise.
2. Remove the empty spool from the string
head. Keep the spring attached to the spool.
3. Remove the last of nylon threads.
4. Cut and hook the nylon inside the spool,
make sure the two strings are captured in the
slots opposite each other on the spool. Make
sure the ends of each string is extended ap-
proximately 152 mm (6 in.) beyond each slot.
5. Thread the strings into
the eyelets in the string
head. Carefully push
the spool into the string
head (gently pull the
strings to the outside if
necessary).
