Lubrication of the cutting equipment
To do a check of the saw chain lubrication
Do a check of the chain saw lubrication each time you
refuel.
1. Start the product and let it run at 3/4 throttle. Aim the
tip of the bar at a light coloured surface about 20 cm
(8 inches) away.
2. After 1 minute running you should see a distinct line
of oil on the light surface.
What to do if the saw chain lubrication is not working
Do the following if the saw chain lubrication is not
working:
• Do a check of the oil channel in the bar to make sure
that it is not obstructed. Clean if necessary.
• Do a check of the groove in the edge of the bar to
make sure that it is clean. Clean if necessary.
• Make sure that the bar tip sprocket turns freely and
that the lubricating hole in the tip sprocket is not
blocked. Clean and lubricate if necessary.
