electric circuitry. Locate and repair the fault (see section on Troubleshooting).
Replacing the dust filter
Dust filters should be inspected for signs of damage every 50 operating
hours. A damaged filter allows dust to be blown into the engine compartment
and surrounding area. A significant build-up of dust at the air exit from the
fan is an indication that the filter is not properly seated or is defective.
