Cleaning; Functional Inspection - Husqvarna K970 II Ring Operator's Manual

Cleaning

External cleaning
• Clean the machine daily by rinsing it with clean water
after the work is finished.
Cooling air intake
• Clean the cooling air intake when needed.
NOTICE! A dirty or blocked air intake results in the
machine overheating which causes damage to the
piston and cylinder.
Spark plug
• If the machine is low on power, difficult to start or runs
poorly at idle speed: always check the spark plug first
before taking other steps.
• Ensure that the spark plug cap and ignition lead are
undamaged to avoid the risk of electric shock.
• If the spark plug is dirty, clean it and at the same time
check that the electrode gap is 0.5 mm. Replace if
necessary.
NOTICE! Always use the recommended spark plug
type! Use of the wrong spark plug can damage the
piston/cylinder.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems and
starting difficulties.
• An incorrect fuel mixture (too much or incorrect type
of oil).
• A dirty air filter.
