Replacing The Fuel Filter; Checking The Fuel Pump's Air Filter; Checking Tire Pressures - Husqvarna EZ4220 Operator's Manual

Replacing the Fuel Filter

Replace the line-mounted fuel filter every 100 hours
(once per season) or more regularly if it is clogged.
Replace the filter as follows:
1. Move the hose clamps away from the filter. Use
flat-nosed pliers.
2. Pull the filter loose from the hose ends.
3. Push the new filter into the hose ends. Position the
filter with the "FLOW" arrow pointing up toward the
fuel pump. If necessary, a soap solution can be
applied to the filter ends to ease mounting.
4. Move the hose clamps back toward the filter.

Checking the Fuel Pump's Air Filter

Regularly check that the fuel pump's air filter is free
from dirt.
Remove the screws and open the pump, no hoses
need be removed.
The filter can be cleaned with a brush if necessary.
Replace the filter on the console.
