IMPORTANT:
Check level of oil every 8 operating
hours or daily. Initially, change oil after the first 8
hours of operation; thereafter, under normal
conditions, change oil after every 50 hours of
operation and filter after every 100 hours of
operation. However, change oil more frequently
when engine is operated in extremely dusty or dirty
conditions, under heavy load or in high ambient
temperatures.
FILL FUEL TANK WITH GASOLINE
This engine is certified to operate on unleaded
gasoline. Use clean, fresh, unleaded gasoline with
a minimum of 85 octane. Do not mix oil with
gasoline. Purchase fuel in quantity that be used
within to 30 days assure fuel freshness. Use Briggs
& Stratton Gasoline Additive (See your Authorized
Briggs & Stratton Service Dealer for Part No. 5041
or the single-use pouch.)
In countries other than the U.S.A., leaded gasoline
may be used if it is commercially available and
unleaded is unavailable.
Note: Some fuels called oxygenated or
reformulated gasolines, are gasoline blended with
alcohols or ethers. Excessive amounts of these
blends can damage the fuel system or cause
performance problems. Do no use gasoline which
contains Methanol. If any undesirable operating
symptoms occur, use gasoline with a lower
percentage of alcohol or ether.
1.
Remove cap from the fuel tank (Fig. 6) and fill the
4.5 gallon tank to within 1 inch from the top with
unleaded gasoline. Install fuel tank cap tightly.
Because gasoline is flammable, caution
must be used when storing or handling it.
Do not fill fuel tank while engine is
running, hot or when machine is in an
enclosed area. Vapors may build up and
be ignited by a spark or flame source
many feet away. DO NOT SMOKE whiIe
filling the fuel tank to prevent the possibil
ity of an explosion. Always fill fuel tank
outside and wipe up any spilled gasoline
before starting engine. Use a funnel or
spout to prevent spilling gasoline before
starting engine and fill tank to about I inch
(25 mm) below the filler neck. Store
gasoline in a clean safety- approved
container and keep the cap in place on the
container. Keep gasoline in a cool, well-
ventilated place; never in an enclosed
area such as a hot storage shed. To
assure volatility, do not buy more than a
30 day supply of gasoline. Gasoline is a
fuel for internal combustion engines;
therefore, do not use it for any other
purpose. Since many children like the
smell of gas, keep it out of their reach
because the fumes are explosive and
dangerous to inhale.
