dealer for safe disposal/recycling facilities.
If oil pressure drops below 1 4 psi (.1 .2 kg/cm
pressure switch (if engine is equipped) will either activate a
warning device or stop the engine. Check oil level with
dipstick. If oil level is between
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 mark on dipstick, add oil to bring
level to mark. Restart engine and check oil pressure.
If pressure is normal, continue to operate engine.
Oil pressure gauge, if engine is equipped, is sup
plied by manufacturer of equipment.
However, to obtain no charge repairs under the terms and
provisions of the Briggs & Stratton warranty statement, any
service or emission control part repair or replacement must
be performed by a factory authorized dealer.
If you perform any maintenance on the
engine, first disconnect the spark plug wires
from the spark plugs, and disconnect the
battery at the negative terminal (electric
starter engines only) to prevent unintentional
sparking. Unintentional sparking can result
in fire or electric shock. Unintentional start
up can result in entanglement, traumatic
amputation or laceration. Use only correct
tools.
• Do not strike the flywheel with hammer or hard
object. If done, the flywheel may shatter during
operation.
• Do not tamper with governor spring, links or other
parts to increase engine speed.
