Spark Plug; Lubricating The Bar Tip Sprocket; Needle Bearing Lubrication; Adjustment Of The Oil Pump - Husqvarna 570 EPA II Manuel D'utilisation

Spark plug

The spark plug condition is influenced by:
• Incorrect carburetor adjustment.
• An incorrect fuel mixture (too much or incorrect type of
oil).
• A dirty air filter.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difficulties.
If the machine is low on power, difficult to start or runs poorly
at idle speed: always check the spark plug first before taking
any further action. If the spark plug is dirty, clean it and check
that the electrode gap is 0.5 mm (0,020"). The spark plug
should be replaced after about a month in operation or earlier
if necessary.
Note! Always use the recommended spark plug type! Use of
the wrong spark plug can damage the piston/cylinder. Check
that the spark plug is fitted with a suppressor.

Lubricating the bar tip sprocket

Lubricate the bar tip sprocket each time you refuel. Use the
special grease gun and a good quality bearing grease.

Needle bearing lubrication

The clutch drum has a needle bearing on the output shaft.
This needle bearing must be lubricated regularly (once a
week). CAUTION! Use only high quality bearing grease or
engine oil. See instructions under the heading Cutting
equipment.
MAINTENANCE

Adjustment of the oil pump

The oil pump is adjustable. Adjustments are made by turning
the screw using a screwdriver or combination spanner. The
machine is supplied from the factory set to 1 turn open.
Turning the screw clockwise will reduce the oil flow and
turning the screw anti-clockwise will increase the oil flow.
Recommended settings:
Bar -15":
Bar 15" -18":
Bar 18" -24":
Bar 24" -:
These recommendations apply to Husqvarna's chain oil, for
other chain oils increase the oil flow by one step.
