Oil Recommendations - Briggs & Stratton Fource 21000 Operating & Maintenance Instructions

WARNING
Gasoline and its vapors are extremely
flammable and explosive.
Fire or explosion can cause severe
burns or death.
WHEN ADDING FUEL
• Turn engine OFF and let engine cool at least 2
minutes before removing gas cap.
• Fill fuel tank outdoors or in well-ventilated
area.
• Do not overfill fuel tank.
• Keep gasoline away from sparks, open
flames, pilot lights, heat, and other ignition
sources.
• Check fuel lines, tank, cap, and fittings
frequently for cracks or leaks. Replace if
necessary.
WHEN STARTING ENGINE
• Make sure spark plug, muffler, fuel cap and air
cleaner are in place.
• Do not crank engine with spark plug removed.
• If fuel spills, wait until it evaporates before
starting engine.
• If engine floods, set choke to OPEN/RUN
position, place throttle in FAST and crank until
engine starts.
WHEN OPERATING EQUIPMENT
• Do not choke carburetor to stop engine.
WHEN TRANSPORTING EQUIPMENT
• Transport with fuel tank EMPTY.
WHEN STORING GASOLINE OR EQUIPMENT WITH
FUEL IN TANK
• Store away from furnaces, stoves, water
heaters or other appliances that have pilot
light or other ignition source because they can
ignite gasoline vapors.
WARNING
Starting engine creates sparking.
Sparking can ignite nearby flammable
gases.
Explosion and fire could result.
• If there is natural or LP gas leakage in area,
do not start engine.
• Do not use pressurized starting fluids
because vapors are flammable.
WARNING
Engines give off carbon monox-
ide, an odorless, colorless, poi-
son gas.
Breathing carbon monoxide can
cause nausea, fainting or death.
• Start and run engine outdoors.
• Do not start or run engine in enclosed area,
even if doors or windows are open.

WARNING
Rapid retraction of starter cord (kick-
back) will pull hand and arm toward
engine faster than you can let go.
Broken bones, fractures, bruises or
sprains could result.
• When starting engine, pull cord slowly until
resistance is felt, then pull rapidly.
• Direct coupled equipment components such
as, but not limited to, blades, impellors,
pulleys, sprockets, etc., must be securely
attached.
WARNING
Rotating parts can contact or en-
tangle hands, feet, hair, clothing, or
accessories.
Traumatic amputation or severe
laceration can result.
• Operate equipment with guards in place.
• Keep hands and feet away from rotating parts.
• Tie up long hair and remove jewelry.
• Do not wear loose-fitting clothing, dangling
drawstrings or items that could become
caught.
WARNING
Running engines produce heat.
Engine parts, especially muffler,
become extremely hot.
Severe thermal burns can occur
on contact.
Combustible debris, such as
leaves, grass, brush, etc. can
catch fire.
• Allow muffler, engine cylinder and fins to cool
before touching.
• Remove accumulated combustibles from
muffler area and cylinder area.
• Install and maintain in working order a spark
arrester before using equipment on forest-
covered, grass-covered, brush-covered
unimproved land. The state of California
requires this (Section 4442 of the California
Public Resources Code). Other states may
have similar laws. Federal laws apply on
federal land.

Unintentional sparking can result
in fire or electric shock.
Unintentional start-up can result in
entanglement, traumatic amputa-
tion, or laceration.
BEFORE PERFORMING
REPAIRS
• Disconnect spark plug wire and keep it away
from spark plug.
WHEN TESTING FOR SPARK
• Use approved spark plug tester.
• Do not check for spark with spark plug
removed.

OIL RECOMMENDATIONS

CAUTION:
Engine shipped from Briggs & Stratton without oil. Before
starting engine, fill with oil. Do not over-fill.
Use a high quality detergent oil classified "For Service SF, SG,
SH, SJ" or higher such as Briggs & Stratton 30, Part Number
100005. Use no special additives with recommended oils. Do
not mix oil with gasoline.
Choose the SAE viscosity grade of oil
Fig. 2
from this chart that matches the starting
temperature anticipated before the next
oil change.
CAUTION:
automotive engines. The use of non-synthetic
multi-viscosity oils (5W-30, 10W-30, etc.) in
temperatures above 40° F (4° C) will result in higher
than normal oil consumption. When using a
multi-viscosity oil, check oil level more frequently.
* CAUTION:
when operating engine under 40° F (4° C) or
engine damage will occur.
** CAUTION:
(10° C), will result in hard starting and possible
engine bore damage due to inadequate
lubrication.
Synthetic oil meeting ILSAC GF-2, API certi-
fication mark and API service symbol (shown
at left) with "SJ/CF ENERGY CONSERVING"
or higher, is an acceptable oil at all temperatu-
res. Use of synthetic oil does not alter required
oil change intervals.
WARNING
ADJUSTMENTS OR
Air cooled engines run hotter than
Synthetic oil must be used
SAE 30 oil, if used below 50° F
