Unintentional sparking can result in fire or electric
shock.
Unintentional start‐up can result in entanglement,
traumatic amputation, or laceration.
BEFORE PERFORMING ADJUSTMENTS OR RE‐
PAIRS
• Disconnect spark plug wire and keep it away from
spark plug.
• Disconnect battery at negative terminal (only
engines with electric start).
WHEN TESTING FOR SPARK
• Use approved spark plug tester.
• Do not check for spark with spark plug removed.
WARNING
Engines give off carbon monoxide, an odorless,
colorless, poison 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
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
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.
WARNING
Rotating parts can contact or entangle 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
Rapid retraction of starter cord (kickback) 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.
• Remove all external equipment/engine loads
before starting engine.
• Direct coupled equipment components such as, but
not limited to, blades, impellors, pulleys, sprockets,
etc., must be securely attached.
WARNING
Oil Recommendations (see fig. )
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
30W, Part Number 100005 (20 oz.) or 100028 (48 oz.).
Use no special additives with recommended oils. Do
not mix oil with gasoline.
Choose the SAE viscosity grade of oil from this chart
that matches the starting temperature anticipated
before the next oil change. (see fig.
)
Note: Synthetic oil meeting ILSAC
GF‐2, API certification mark and API ser‐
vice symbol (shown at left) with “SJ/CF
ENERGY CONSERVING” or higher, is an
acceptable oil at all temperatures. Use of
synthetic oil does not alter required oil
change intervals.
* Air cooled engines run hotter than 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.
** Use of SAE 30 oil below 40° F (4° C) will result in
hard starting and possible engine damage due to
inadequate lubrication.
Check oil level (see fig.
)
Oil capacity is about 1.8 liters (60 ounces) if engine is
not
equipped with oil filter. Oil capacity is about 1.9 liters
(64 ounces) if engine is equipped with oil filter.
Note: Oil capacity will be greater if engine is equipped
with remote
oil filter.
Place engine level and clean around oil fill
Ê.
Remove dipstick
Ë, wipe with clean cloth, insert and
tighten down again. Remove dipstick and check oil level.
Oil should be at FULL mark
Ì. If oil is required, add
slowly. Tighten dipstick firmly before starting engine.
After filling with or changing oil, start and run engine at
idle for 30 seconds. Shut engine off. Wait 30 seconds
and check oil level. Check for oil leaks. Add oil, if
required, to bring level to FULL mark on dipstick.
Fuel Recommendations
Use clean, fresh, regular lead‐free gasoline with a
minimum of 85 octane. Leaded gasoline may be used if
it is commercially available and if unleaded is unavail‐
able. Purchase fuel in quantity that can be used within
30 days. See Storage.
In U.S.A. leaded gasoline may not be used. Some
fuels, called oxygenated or reformulated gasolines, are
gasolines blended with alcohols or ethers. Excessive
amounts of these blends can damage the fuel system
or cause performance problems. If any undesirable
operating symptoms occur, use gasoline with a lower
percentage of alcohol or ether.
This engine is certified to operate on gasoline. Exhaust
Emission Control System: EM (Engine Modifications).
Do not use gasoline which contains Methanol. Do not
mix oil with gasoline.
For engine protection, we recommend using Briggs &
Stratton Fuel Stabilizer available from an Authorized
Briggs & Stratton Service
Dealer.
