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.
