Remove the air filter cover and take out the filter. Wash it
clean in warm, soapy water.
If the machine is used in dusty conditions the air filter
should be soaked in oil. See instructions under the
heading Oiling the air filter.
An air filter that has been in use for a long time cannot be
cleaned completely. The filter must therefore be replaced
with a new one at regular intervals.
A damaged air filter
must always be replaced.
• Refit the air filter and air filter cover.
Oiling the air filter
560BTS, BFS
Always use special filter oil. Filter oil contains a solvent to
make it spread evenly through the filter. You should
therefore avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour
off the excess before fitting the filter to the machine. Never
use common engine oil. This would drain through the filter
quite quickly and collect in the bottom.
Shoulder strap
If the shoulder strap is damaged, it may break while in use
and the machine may fall causing personal injury. Follow
the instructions below to replace the shoulder strap.
1 Remove the clamp from the strap.
2 Run the end of the strap through the hanger.
3 Refit the clamp to the strap.
!
WARNING! Check that the thick round
pin in the clamp is inserted in the strap. If
it is inserted incorrectly it may lead to
personal injury.
