oil pressure switch (if equipped) will either activate a
warning device or stop the engine. Check oil level with
dipstick. If oil level is between ADD and FULL mark on
dipstick do not try to restart engine. Contact an
authorized Briggs & Stratton Service Dealer. Do not
operate engine until oil pressure is corrected.
If oil level is below ADD mark on dipstick, add oil to
bring level to FULL mark. Restart engine and check oil
pressure. If pressure is normal, continue to operate
engine.
Note: Oil pressure gauge( if engine is equipped) is
supplied by manufacturer of equipment.
