Fuel System
Filter Change
The Boxer 1800 is equipped with a spin on fuel filter (1)
located in the front of the engine compartment under the
operator station.
To change the filter lift up and secure the rubber flap open
to gain access to the filter.
• Clean filter head and sounding areas to keep fuel
system clean.
• Place a small catch pan under the filter to contain
any spilled fuel.
• Using a filter wrench loosen the filter and remove.
• Before installing the new filter, lubricate the sealing
ring with fuel and fill the filter with clean fuel up to
the threads.
• Install the new filter hand tight, and with a wrench
give an additional 1/4 turn.
Note: When the fuel filter has been changed air enters
the fuel system. By pre filling the fuel filter it reduces the
amount of air that enters the system.
When starting the machine for the first time after the fuel
filter change:

• Set throttle lever at about 1/4 speed
• Let run for 5 minutes to purge the air form the
system.
If the engine stops after restart, start the engine again. If
the engine does not re start it may be necessary to use
the primer pump (2) on the engine located just below the
coolant purge tank.
