C. ENGINE MAINTENANCE

ENGINE OIL LEVEL

Engine oil level must be checked at regular intervals to
ensure that engine oil is maintained at a level that will
provide for adequate lubrication of internal components.
Operating the engine with insufficient oil in the oil sump
will cause engine components to wear prematurely, and
prolonged use with low oil levels may cause engine over-
heating, permanent damage, and voiding of the engine
manufacturer's warranty.
In addition to following the engine manufacturer's instruc-
tions for checking oil level, the recommendations for oil
type and viscosity must also be followed. These recom-
mendations vary based on the season during which the
unit is being operated, and may require that the oil be
changed to suit different operating conditions.
The location of the oil level indicator and oil fill tube are
indicated in the engine manufacturer's manual shipped
with each unit. In general, the oil fill tube is marked with
an oil can symbol or the word "OIL", and is located next
to the engine to permit easy access (See Figure 1).
The engine oil fill tube is usually also the location of the
engine oil level dipstick, allowing oil level checks and fill-
ing to be performed using the same tube.
ENGINE OIL FILTER (WHERE
APPLICABLE)
The engine oil filter should be changed in accordance
with the engine manufacturer's recommendations, which
is generally every 100 hours of operation, or more fre-
quently when operating conditions are hot (over 85°), or
dusty.
The oil filter removes abrasive particles and other conta-
minants from the oil, keeping it clean for maximum lubri-
cation efficiency, and should only be replaced with the
type of filter recommended by the engine manufacturer.
The oil filter is located at the base of the engine, and is
removed by unscrewing the filter from the filter base
using an oil filter wrench.

ENGINE AIR FILTER

The engine air filter filters out dust and dirt from the air
intake of the engine, and must be cleaned or replaced
every 25 hours of operation, or more frequently when
operating conditions are dusty.
Follow the engine manufacturer's recommendations for
removal, cleaning, and replacement. See Figure 1for air
filter locations.

FUEL FILTER

Do not remove fuel filter when engine is hot, as
spilled gasoline may ignite. Follow all precau-
tions for the safe handling of gasoline when
removing and installing the fuel filter. DO NOT
spread hose clamps more than necessary.
Replace clamps if they do not provide a secure,
leak-proof attachment to the fuel filter when rein-
stalled.
The fuel filter is located in the engine compartment and
is installed in the rubber fuel line between the fuel tank
and the fuel pump. The fuel filter should be checked
every 100 hours of operation, or sooner and replaced if it
appears to be dirty or clogged.
A dirty or clogged filter may cause erratic engine opera-
tion, hard starting, or loss of power.
Before removing the hoses from the fuel filter, place a
small container under the filter to catch the gasoline in
the hoses and filter that will drain out as the filter is
removed.
1. Squeeze the tabs on the hose clamps together using
a pliers, and slide the clamps away from the fuel fil-
ter.
2. Note the fuel flow direction indicated on the filter, and
remove the filter by pulling the hoses away from the
filter with a twisting motion. Be prepared for fuel in
the hoses and fuel filter to drain out as the hoses are
disconnected, and catch the fuel in the container.
3. Observing the same fuel filter flow direction noted
during removal, install the new fuel filter in the fuel
line by sliding the hoses onto the filter.
4. Squeeze the tabs on the hose clamps together, and
slide the clamps into place over the fuel filter tubes to
secure the fuel lines to the fuel filter.
NOTE: The hose clamps must connect the fuel line
hoses to the fuel filter securely to prevent fuel leakage
and the possibility of engine compartment fire. Replace
the hose clamps if they do not provide a secure, leak-
proof attachment to the fuel filter.
NOTE: Replace old, brittle, hard, or cracked fuel line.
