Maintenance - Homelite UT21566 Operator's Manual

 Find the middle of the string section. Loop the string
around the hook in the center of the spool (figure 13).
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 cleaned or replaced every 25
hours or yearly to ensure proper performance of the product.
Spark arrestors 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.
