MAINTENANCE

installing string in pro cut II string head

See Figure 29.

Use monofilament string between .095 in. and .105 in. di- ameter. Use original manufacturer’s replacement string for best performance.

Stop the engine and disconnect the spark plug wire.

Gather two of the pre-cut lengths of trimmer line provided or cut two pieces of trimmer line, in 11 in. lengths.

Insert the strings into the slots located on the sides of the string head. String should be pushed in until approxi- mately 1 in. protrudes from the holes on the top of the string head.

Remove old string by pulling it from the holes located on the top of the string head.

CLEANING THE EXHAUST PORT AND MUFFLER

NOTE: Depending on the type of fuel used, the type and amount of lubricant used, and/or your operating conditions, the exhaust port, muffler, and/or spark arrestor screen 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 50 hours or yearly to ensure proper performance of your prod- uct. 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.

Idle Speed Adjustment

See Figure 30.

If the cutting attachment turns at idle, the idle speed screw needs adjusting on the engine. Turn the idle speed screw counterclockwise to reduce the idle RPM and stop the cut- ting attachment movement. If the cutting attachment still moves at idle speed, contact a service dealer for adjustment and discontinue use until the repair is made.

WARNING:

The cutting attachment should never turn at idle. Turn the idle speed screw counterclockwise to reduce the idle RPM and stop the cutting attachment, or contact a service dealer for adjustment and discontinue use until the repair is made. Serious personal injury may result from the cutting attachment turning at idle.
