SPROCKET
1. A damaged sprocket wiIl cause premature damage or
wear of a saw chain.
2. When the sprocket has worn out 0,5 mm or more,
replace it.
3. Check sprocket when you install new chain. Replace
it if worn.
AUTOMATIC OILER
1. The discharge volume of the automatic oiler is adjusted
to 7 mL/min approximately at 7,000 r/min, prior to
shipment from factory.
2. To increase the deliverly volume, tum the adjusting
screw anticlockwise. When the adjusting screw touches
the stop and stops, this position indicates maximum
discharge volume. (13 mL/min 7,000 r/min).
3. Do not turn the adjusting screw beyond the maximum
or minimum Iimit of volume adjustment.
SPARK PLUG
1. Check penodically.
2. The standard spark gap is 0,5 to 0,6 mm.
3. Correct the spark gap if it is wider or narrower than the
standard gap.
4. Fastening torque: 15 to 17 N-m (150 to 170 kgf-cm).
MAGNETO
1. The unit has a digital system, which does not require
adjustment of ignltion timing.
2. Check for secure (tight) wire connections.
CYLINDER FINS
1. Check periodically.
2. Clogged fins will result in poor engine cooling.
3. Remove dirt and dust from between fins to let cooling
air pass easily.
CHAIN
1. Never operate a chain saw with a dull or damaged chain.
If the chain requires excessive pressure to cut or
produces dust instead of wood chips then inspect the
cutters for damage.
2. When sharpning the chain the objectives wilI be to
maintain the same angles and profiles throughout its
life as when it was new. Inspect the chain for damage
or wear every time you refuel your chain saw. When
the length of the cutting teeth has worn down to only 4
mm the chain must be replaced.
3. In order to file the chain correctly you need: round file
and file holder, flat file and a depth gauge tool.
4. By using the correct file size (4,0 mm round file) and a
file holder, it is easier to receive a good result.
5. Consult your dealer IBEA for correct sharpening tools
and sizes.
