GUIDE BAR
• Clean before using.
• Clean the groove of the guide bar with for
example a small screw drive.
• Clean oil holes with a wire.
• Reverse guide bar periodically.
• Clean sprocket, clutch and bar mount area
before installation of guide bar.
NOTE
When replacing guide bar or saw chain, ask your
dealer.
AUTOMATIC OILER
• The discharge volume of the automatic oiler
is adjusted to 7 mL/min approximately at
7,000 r/min, prior to shipment from factory.
• To increase the delivery volume, turn the
adjusting screw anticlockwise. When the
adjusting screw touches stopper and stops,
this position indicates maximum discharge
volume. (13 mL/min 7,000 r/min)
• Do not turn the adjusting screw beyond the
max. or min. limit of volume adjustment.
MAGNETO
• The unit has CDI (Capacitor Discharge
Ignition) system, which does not require
adjustment of ignition timing.
• Check for secure (tight) wire connections.
SPROCKET
• The damaged sprocket will cause premature
damage or wear of saw chain.
• When the sprocket has worn out 0.5mm or
more replace it.
• Check sprocket when you install new chain.
• Replace it if worn
.
SPARK PLUG
• Check periodically.
• The standard spark gap is 0.6 to 0.7 mm.
Correct the spark gap if it is wider or narrower
than the standard gap.
• Fastening torque: 15 to 17 N • m
(150 to 170 kgf•cm)
CYLINDER FINS
• Check periodically.
•
Clogged fins will result in poor engine
cooling.
•
Remove dirt and dust from between fins to let
cooling air pass easily.
