WARNING
Fuel leaked or spilled onto hot surfaces or electrical
components can cause a fire. To help prevent possible
injury, turn the ignition switch off when changing fuel
filters or water separator elements. Clean up fuel spills
immediately.
Check/Add Engine Oil Level
Interval:
Before each use.
1. Use the engine oil dipstick (A, Figure 27) to check the
engine oil level.
27
2. If the engine oil level is low, add engine oil through
the engine oil fill (B). Refer to the
Lubricant Viscosity
Recommendations
for specific oil recommendations.
Lubrication Viscosity Recommendations
Use API CK-4 rated oil.
The proper SAE viscosity grade of oil is determined by the
minimum ambient temperature during cold engine start-
up, and the maximum ambient temperature during engine
operation.
Refer to figure 28 (minimum temperature) to determine a
required oil viscosity for starting a cold engine.
Refer to figure 28 (maximum temperature) to select the
oil viscosity for engine operation at the highest ambient
temperature that is anticipated.
Note:
Generally, use the highest oil viscosity that is available
to meet the requirement for the temperature at start-up.

Engine Maintenance
For engine maintenance schedules and procedures, please
refer to the engine operator's manual.
Clean the Engine Compartment Area
with Pressurized Air and Water
Pressurized air and/or water can cause debris and/or hot
water to be blown out. This action could result in personal
injury.
When pressurized air and/or pressurized water is used for
cleaning wear protective clothing, protective shoes, and eye
protection. Eye protection includes goggles or a protective
face shield.
The maximum air pressure for cleaning purposes must be
below 205 kPa (30 psi). The maximum water pressure for
cleaning purposes must be below 275 kPa (40 psi).
Check/Add Coolant Level
WARNING
If engine is warm, DO NOT remove radiator cap.
Escaping steam can cause burns.
Never remove the radiator cap or radiator reservoir cap
while the engine is hot or running. Severe thermal burns or
injury can occur by escaping steam or hot coolant.
• Do NOT touch hot radiator or open reservoir when
engine is running.
• Stop and allow engine to cool before removing the
radiator cap or the reservoir cap and before changing or
adding coolant.
The engine coolant level and quality should be checked
before each use when the engine is cool and off.
1. Remove the radiator cap (A, Figure 29) to check the fluid
level.
