Maintenance - Urrea DG927 Manual De Usuario

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 oil drip-
ping from the muffler.
ADVANCING THE STRING
String advance is con-
trolled by tapping
string head on grass
while running engine
at full throttle.
1. Run engine at full
throttle.
2. Tap string head on ground to advance string.
String advances each time the head is tapped.
NOTE: Several taps may be required until string
strikes the cut off blade.
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; this 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 CUT-OFF
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.
NOTE: Advance string whenever you hear the
engine running faster than normal.
This will maintain best performance and keep
string long enough to advance properly.

Failure to do so can cause possible injury, poor
performance and may void your warranty.
REPLACING THE NYLON THREAD
1. Hold the string head
and unscrew the spool
retainer.
Turn counterclock-
wise.
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 (gen-
tly pull the strings to
the outside if neces-
sary).
When the spool is positioned in the string
head, grasp the strings and pull sharply to re-
lease them from the slots in the spool.
6. Push down and turn the spool counterclock-
wise until it no longer turns. Hold the spool
down and rotate clockwise a small amount.
Release the spool. The spool should be locked
down in the string head. If not, hold down and
rotate until locked.
7. Make sure the string head and the spool re-
tainer are installed on the drive shaft by turn-
ing the retainer clockwise to tighten.
8. Pull the strings again to rotate the spool into
cutting position. Push the spool retainer down
while pulling on string(s) to manually advance
the string and to check for proper assembly of
the string head.
