BRIGGS & STRATTON TIPS

IMPORTANT TIPS FOR CARE OF THE BRIGGS & STRATTON ENGINE

Fuel System

Fuel must be clean - free from water, dirt, and or- ganic material.

Clean the fuel filter on a regular basis and when contamination is suspected or found in the fuel.

Starting

Start engine with the throttle advanced off idle (1/4 to 1/2 throttle). This will aid starting, especially in cold weather.

Keep the battery fully charged.

Match crankcase oil viscosity to the ambient tem- perature, allowing the engine to crank faster and start easier.

Allow engine to run at idle for a few seconds be- fore stopping engine to avoid run-on or backfiring.

Cooling System

Keep engine air intake screen and cylinder head fins free of grass clippings, chaff, and dirt. Inspect intake screen and cooling fins for cleanliness and damage.

Operate the engine at full speed when mowing. This will allow the engine to produce full horsepower and move more cooling air through the engine cool- ing fins.

Air Cleaner

Use only Briggs & Stratton air cleaner elements. Aftermarket elements may not seal in the air cleaner housing, allowing dirt to enter the engine. Also, af- termarket filters often skimp on the filtration media and require more frequent cleaning and replace- ment.

DO NOT overservice or frequently “disturb” the air filter. A dirty air filter actually cleans better than a new one. Changing and cleaning the filter too of- ten can actually reduce filter efficiency and increase the opportunity for traces of dust to enter the engine. Wait until the element really needs servicing as indi- cated by the loss of engine power.

When the air filter element is removed or re- placed, make sure all dust is cleaned out of the air cleaner body. Use a damp cloth and wipe the inte- rior of the air cleaner body clean (a little dirt left here will be sucked into the engine and reduce engine life). When the filter is reinstalled, make sure the el- ement is held tight and straight in the air cleaner body for proper seating and sealing.

Oil

Single viscosity or multi-viscosity oils may be used with the viscosity matching ambient tempera- tures for the engine operating conditions. This will aid starting in cold weather and assure proper lu- brication in hot weather.

Use only Briggs & Stratton oil filters. Aftermarket filters may not seal properly and/or have the in- correct pressure relief valve for proper lubrication.
