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.

* Below 40^ (4^) the use of SAE 30 will result in hard starting.
** Above 80^ ( 27^ ) the use of 10W-30 may cause increased oil consumption. Check oil level more frequently.

How To Check/Add Oil - Figure ② ④

Before adding or checking the oil

• Place engine level.
  Clean the oil fill area of any debris.
• Remove the dipstick (A) and wipe with a clean cloth (Figure 2).
• Completely insert the dipstick.
• Remove the dipstick and check the oil level. It should be at the FULL mark (B) on the dipstick.
• 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.

• 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).

• 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.
• Clean the fuel cap area of dirt and debris. Remove the fuel cap (A, Figure 5).
• 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).

About Your Warranty

Briggs & Stratton welcomes warranty repair and apologizes to you for being inconveniently. Any Authorized Briggs & Stratton 3/LC Service Dealer may perform warranty repairs. Most warranty repairs are handled routinely, but sometimes requests for warranty service may not be appropriate. For example, warranty would not apply if engine damage occurred because of misuse, lack of routine maintenance, shipping, handling, warehousing or improper installation. Similarly, warranty is void if the serial number of the engine has been removed or the engine has been altered or modified.

If a customer differs with the decision of the Service Dealer, an investigation will be made to determine whether the warranty applies. Ask the Service Dealer to submit all supporting facts to his Distributor or the Factory for review. If the Distributor or the Factory decides that the claim is justified, the customer will be fully reimbursed for those items that are defective. To avoid misunderstanding which might occur between the customer and the Dealer, listed below are some of the causes of engine failure that the warranty does not cover.

Normal wear: Engines, like all mechanical devices, need periodic parts service and replacement to perform well. Warranty will not cover repair when normal use has exhausted the life of a part or an engine. Warranty would not apply if engine damage occurred because of misuse, lack of routine maintenance, shipping, handling, warehousing or improper installation. Similarly, warranty is void if the serial number of the engine has been removed or the engine has been altered or modified.

Improper maintenance: The life of an engine depends upon the conditions under which it operates, and the care it receives. Some applications, such as tillers, pumps and rotary mowers, are very often used in dusty or dirty conditions, which can cause what appears to be premature wear. Such wear, when caused by dirt, dust, spark plug cleaning grit, or other abrasive material that has entered the engine because of improper maintenance, is not covered by warranty.

This warranty covers engine related defective material and/or workmanship only, and not replacement or refund of the equipment to which the engine may be mounted. Nor does the warranty extend to repairs required because of:

1 Engines that are not properly applied to equipment. It is strongly recommended that the factory be contacted prior to applying a B&S 3/LC engine to equipment that did not originally use a B&S 3/LC engine.
2 Problems caused by parts that are not original Briggs & Stratton parts.
3 Equipment controls or installations that prevent starting, cause unsatisfactory engine performance, or shorten engine life. (Contact equipment manufacturer.)

4 Leaking carburetors, clogged fuel pipes or injectors, sticking valves, contaminated injector pumps, or other damage, caused by using contaminated or stale fuel. Use clean, fresh fuel (lead free gasoline, diesel fuel) and Briggs & Stratton fuel stabilizer, Part No. 5041.
5 Parts which are scored or broken because an engine was operated with insufficient or contaminated lubricating oil, or an incorrect grade of lubricating oil (Check oil level daily or after every 8 hours of operation. Refill when necessary and change oil and oil filter at recommended intervals). OIL GARD may not shut down running engine. Engine damage may occur if oil level is not properly maintained. Read Operator's Manual.
6 Repair or adjustment of associated parts or assemblies such as clutches, transmissions, remote controls, etc., which are not manufactured by Briggs & Stratton.
7 Damage or wear to parts caused by dirt, which entered the engine because of improper air cleaner maintenance, re-assembly, or use of a non-original air cleaner element or cartridge. At recommended intervals, clean and/or replace the filter as stated in the Operator's Manual.
8 Parts damaged by over-speeding, or overheating caused by grass, debris, or dirt, which plugs, clogs radiator or air cooling access openings, or damage caused by operating the engine in a confined area without sufficient ventilation. Engine damage caused by not using accurate mix of anti-freeze and tap water, or water entering the engine due to any cause.
Engine or equipment parts broken by excessive vibration caused by a loose engine mounting, loose cutter blades, unbalanced blades or loose or unbalanced impellers, improper attachment of equipment to engine crankshaft, over-speeding or other abuse in operation.
10 Routine tune-up or adjustment of the engine.
11 Engine or engine component failure, i.e., combustion chamber, valves, valve seats, valve guides, or burned starter motor windings, caused by the use of alternate fuels such as, liquified petroleum, natural gas, altered gasolines, etc.

You are responsible for presenting your engine to an Authorized B&S Service Dealer as soon as a problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.
