PERIODIC
MAINTENANCE
AIR
CLEANER
If air cleaner becomes too dirty, engine will not receive sufficient air
to run properly. Symptoms: Loss of power, flooding, hard starting
and overheating.
The BF engine isequipped with a paper element and a
polyurethane pre-cleaner that must be removed,
cleaned and oiled every 25 hours of operation, or
more often under extremely dusty conditions.
2.
Depending on conditions in which the welder is
operating,
the inner paper element should be
replaced whenever it becomes excessively dirty.
CAUTION
Never run the engine with the air cleaner
removed.
Dirt will enter the engine and score
the cylinders.
1.
To clean polyurethane pre-cleaner, wash in water
and detergent. Remove excess water by squeez-
ing like a sponge and allow to dry thoroughly.
Distribute three tablespoons of SAE 30 engine oil
evenly around the pre-cleaner. Knead into pre-
cleaner and wring out excess oil.
CRANKCASE BREATHER *
The crankcase breather valve maintains crankcase
vacuum.
No maintenance is generally required. Ifthe
crankcase becomes pressurized as evidenced by oil
leaks at the seals, clean baffle and valve in a suitable
solvent (Figure 2).
