STRING REPLACEMENT
See Figures 16 - 19.
n  Stop the engine, disconnect the spark plug wire. Hold the 
string head and unscrew the spool retainer. 
  To remove the spool retainer: 
  Turn the spool retainer counterclockwise for Trimlite and 
Trim n’ Edge. 
  Turn the spool retainer clockwise for Easy Reach. 
n  Remove the spool from the string head. 
  NOTE:  Keep the spring attached to the spool. Remove 
any old string remaining on the spool. 
n 
Cut two pieces of string, each being approximately 9 ft. 
(2.7 m) long. Use only .080 in. (2.0 mm) diameter mono-
filament string. 
n  Insert the first string into the anchor hole in the upper part 
of the spool. Wind the first string around the upper part of 
the spool counterclockwise, as shown by the arrows on 
the spool. Place string in the slot on upper spool flange, 
leaving about 6 in. (152 mm) extended beyond the slot. 
Do not overfill. After winding the string, there should be 
at least 1/4 in. (6 mm) between the wound string and the 
outside edge of the spool.
n  Repeat above step with second string, using the bottom 
part of spool. Do not overfill.
n  Replace the spool and the spool retainer. Refer to “Spool 
Replacement” earlier in this manual.
CLEANING THE EXHAUST PORT AND 
MUFFLER
NOTE: Depending on the  type of fuel used, the type and 
amount  of oil  used, and/or  your  operating conditions,  the 
exhaust port, muffler, and/or spark arrestor screen may be-
come blocked with carbon deposits. If you notice a power loss 
with your gas powered tool, you may need to remove these 
deposits to restore performance. We highly recommended 
that only qualified service technicians perform this service.
SPARK ARRESTOR
The spark arrestor must be cleaned or replaced every 25 
hours or yearly to ensure proper performance of your product. 
Spark arrestors may be in different locations depending on 
the model purchased. Please contact your nearest service 
dealer for the location of the spark arrestor for your model.
