CARBURETOR ADJUSTMENT
WARNING: If any adjustments are
made to the engine while the engine is
running (e.g. carburetor), disengage all
clutches and blades. Keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
NOTE: A dirty air cleaner will cause an engine to
run rough. Be certain it is clean and properly
attached before adjusting carburetor. Refer to
separate engine manual packed with your unit for
information regarding air cleaner maintenance.
Refer to separate engine manual packed with your
unit for carburetor adjustment information or see an
authorized Briggs & Stratton service dealer.

wire(s) and ground against the engine
before performing any adjustments, repairs
or maintenance.
ENGINE
Refer to the separate engine manual for engine
maintenance instructions.
Check engine oil level before each use as
instructed in the separate engine manual packed
with your unit. Read and follow instructions
carefully.
Changing Engine Oil
• Unscrew oil fill cap and remove dipstick from
the oil fill tube. See Figure 12.
Figure 12
• Pop open the protective cap on the end of the
oil drain valve to expose the oil drain port. See
Figure 12.
• Push oil drain hose (packed with unit) onto the
oil drain port. Route the opposite end of the
hose into an appropriate oil collection
container with a capacity great enough to
collect the used oil.
• Push the oil drain valve in slightly, then rotate
counterclockwise and pull outward to begin
draining oil. See Figure 12.
• Service the oil filter (if so equipped) as
instructed in the separate engine manual
packed with your unit.
Perform the above steps in the opposite order after
oil has finished draining.
• Refill the engine with new motor oil.
IMPORTANT: Refill the engine with the proper
capacity and weight of motor oil as instructed in the
separate engine manual.
Service air cleaner every 25 hours under normal
conditions. Clean every few hours under extremely
dusty condition. To service the air cleaner, refer to the
separate engine manual packed with your unit.
The spark plug(s) should be cleaned and the gap
reset once a season. Replacement is recommended
at the start of each mowing season; check engine
manual for correct plug type and gap specifications.
CLEANING THE ENGINE AND DECK
Any fuel or oil spilled on the machine should be
wiped off promptly. Do NOT allow grass, leaves, and
dirt to accumulate around the cooling fins of the
engine or on any other part of the machine,
especially the pulleys and other moving parts. Clean
the underside of the deck with a wisk broom, putty
knife or forced air after each mowing.
IMPORTANT: The use a pressure washer or
garden hose to clean your tractor is NOT
recommended. It may cause damage to electrical
components, spindles, pulleys, bearings or the
engine. The use of water will result in a shortened
life of the tractor and reduce its serviceability.
