The following guidelines are provided for routine main-
tenance.
I:3 Replace the oil supply line filter. The line filter car-
tridge must be replaced to avoid contamination of
the fuel pump and nozzle.
I:3 Inspect the oil supply system. All fittings should be
tight and leak=free. The supply lines should be free
of water, sludge and other restrictions.
I:3 Remove and clean the pump strainer if applica-
ble.

nual basis, to remove any build-up or dark stains
from the windows.
