Oil Recommendations
We recommend the use of Briggs & Stratton Warranty Certified oils for best
performance. Other high-quality detergent oils are acceptable if classified for service CF
or CF-4. Do not use special additives.
Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to
select the best viscosity for the outdoor temperature range expected.

How To Check/Add Oil -
Figure

Before adding or checking the oil
•
Place engine level.
•
Clean the oil fill area of any debris.
1. Remove the dipstick (
A
) and wipe with a clean cloth (Figure 2).
2. Completely insert the dipstick.
3. Remove the dipstick and check the oil level. It should be at the FULL mark (
B
) on the
dipstick.
4. If low, remove the dipstick and add oil slowly into the engine oil fill (
C
).
Do not
overfill.
Important:
When adding oil, adequate venting is required as follows:
•
Remove the dipstick.
•
Make sure adequate clearance (
D
) is maintained between the oil fill device (
E
)
and the engine oil fill (
C
). See Figure 4.
5. After adding oil, install the dipstick. Start and run engine at idle for five minutes. Shut
off engine. Wait three minutes and check oil level. If required, add oil to bring oil level
to the FULL mark (
B
) on the dipstick (Figure 2).
6. Install the dipstick.
Oil Pressure
If the oil pressure is too low, a pressure switch (if equipped) will either stop the engine or
activate a warning device on the equipment. If this occurs, stop the engine and check the
oil level with the dipstick.
If the oil level is below the ADD mark, add oil until it reaches the FULL mark. Start the
engine and check for proper pressure before continuing to operate.
If the oil level is between the ADD and FULL marks,
do not start
the engine. Contact
any Briggs & Stratton 3/LC Authorized Dealer to have the oil pressure problem
corrected.
Fuel Recommendations
Fuel must meet these requirements:
•
This engine is certified to operate on diesel fuel. If incorrect fuel is used, black
smoke, power loss, and damage to the engine will occur, which will not be
covered by the warranty.
•
Use clean, fresh diesel fuel with a
minimum of 40 cetane
. Fresh fuel prevents gum
from forming in the fuel system. Purchase fuel in a quantity that can be used within
30 days. See the
Storage
section.
CAUTION:
Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this
caution will damage the engine and
void the engine warranty
.
How To Add Fuel -
Figure
5
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Adding Fuel
•
Turn engine off and let engine cool at least 2 minutes before removing the fuel cap.
•
Fill fuel tank outdoors or in well-ventilated area.
•
Do not overfill fuel tank. Fill tank to approximately 1.5 inches (38 mm) below top of
neck to allow for fuel expansion.
•
Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition
sources.
•
Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if
necessary.
•
If fuel spills, wait until it evaporates before starting engine.
1. Clean the fuel cap area of dirt and debris. Remove the fuel cap (
A
, Figure 5).
2.
Fill the fuel tank (
B
) with fuel. To allow for expansion of the fuel, do not fill above the
bottom of the fuel tank neck (
C
).
3. Reinstall the fuel cap.
Coolant Recommendations
Coolant capacity (see the equipment manufacture’s manual)
Important:
This is a liquid-cooled engine. A 50/50% mixture of phosphate-free
antifreeze and tap water is required for cooling, rust resistance, and lubrication of the
water pump.
How To Check/Add Coolant
Severe thermal burns can occur by escaping steam or hot coolant.
WARNING
•
DO NOT remove radiator cap or reservoir cap if engine is warm or running.
•
Stop engine and allow it to cool before removing radiator cap or reservoir cap and
before changing or adding coolant.
1. Before operating, check the coolant level. The coolant level must be between the
FULL and the LOW/ADD marks on the coolant reservoir. If the coolant level is low,
add a 50/50% coolant mixture of phosphate-free antifreeze and tap water to the
reservoir.
2. To remove the reservoir cap after engine is cool, place a thick cloth over the reservoir
cap. Slowly turn the reservoir cap counterclockwise to remove.
3. If the reservoir is dry, then add coolant to both the reservoir and to the radiator. See
the equipment manual for location, operation, and maintenance of the coolant
reservoir and the radiator.
