STRING REPLACEMENT

Stop the engine and 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 MightyLite
26CS.
Turn the spool retainer clockwise for MightyLite 26SS.

Remove the spool from the string head.
NOTE: Keep the spring attached to the spool. Remove
any old string remaining on the spool.
 For the MightyLite 26CS: Cut one piece of trimmer line
9 ft. long. Find the hole in the center of the spool (figure
14). Insert one end of the line into the hole. Carefully wind
the string in the direction indicated on the top of the spool.
Nearing the end of the string, slide the end of the string
into the nearest open slot on the spool. Do not overfill.
For the MightyLite 26SS: Cut one piece of trimmer line
18 ft. long. Find the middle of the string section. Loop the
string around the hook in the center of the spool (figure
15). Carefully wind the string in the direction indicated on
the top of the spool. Nearing the end of the string, slide
one end of the string into each slot of the spool. Do not
overfill.
 Replace the spool and the spool retainer. Refer to Spool
Replacement earlier in this manual.
CLEANING THE EXHAUST PORT
Depending on the type of fuel used, the type and amount
of lubricant used, and/or your operating conditions, the
exhaust port may become 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 recommend that only qualified service technicians
perform this service.
SPARK ARRESTOR
The spark arrestor must be replaced every 50 hours or yearly
to ensure proper performance of the product. Spark arres-
tors may be in different locations depending on the model
purchased. Please contact the nearest service dealer for the
location of the spark arrestor for your model.
