MAINTENANCE
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.
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.
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.
Functional inspection
General inspection
• Check that nuts and screws are tight.
Guide rollers
Lubricating the guide rollers
• Connect the grease gun to the grease nipples.
• Pump in grease until clean grease emerges from the
overflow hole.
Replacing the support guide rollers
Replace the guide rollers when half of the flange on the rollers
is worn.
1) New, 3 mm (0.12’’)
2) Worn,
≤
1,5 mm (0.06’’)
• Remove the support roller cover.
NOTICE! A dirty or blocked air intake results in the machine
overheating which causes damage to the piston and
cylinder.
NOTICE! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/
cylinder.
