Safety Information
WARNING
Gasoline and its vapors are extremely
flammable and explosive.
Fire or explosion can cause severe
burns or death.
WHEN ADDING FUEL
S Turn engine OFF and let engine cool at least 2
minutes before removing gas cap.
S Fill fuel tank outdoors or in well-ventilated
area.
S Do not overfill fuel tank.
S Keep gasoline away from sparks, open
flames, pilot lights, heat, and other ignition
sources.
S Check fuel lines, tank, cap, and fittings
frequently for cracks or leaks. Replace if
necessary.
WHEN STARTING ENGINE
S Make sure spark plug, muffler, fuel cap and air
cleaner are in place.
S Do not crank engine with spark plug removed.
S If fuel spills, wait until it evaporates before
starting engine.
S If engine floods, set choke to OPEN/RUN
position, place throttle in FAST and crank until
engine starts.
WHEN OPERATING EQUIPMENT
S Do not choke carburetor to stop engine.
WHEN TRANSPORTING EQUIPMENT
S Transport with fuel tank EMPTY.
WHEN STORING GASOLINE OR EQUIPMENT
WITH FUEL IN TANK
S 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
Engines give off carbon monoxide, an
odorless, colorless, poison gas.
Breathing carbon monoxide can
cause nausea, fainting or death.
S Start and run engine outdoors.
S 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.
S If there is natural or LP gas leakage in area, do
not start engine.
S Do not use pressurized starting fluids because
vapors are flammable.
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.
S When starting engine, pull cord slowly until
resistance is felt, then pull rapidly.
S Direct coupled equipment components such as,
but not limited to, blades, impellers, pulleys,
sprockets, etc., must be securely attached.

Safety Information
WARNING
Rotating parts can contact or entangle
hands, feet, hair, clothing, or accessories.
Traumatic amputation or severe laceration can result.
S Operate equipment with guards in place.
S Keep hands and feet away from rotating parts.
S Tie up long hair and remove jewelry.
S 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.
S Allow muffler, engine cylinder and fins to cool
before touching.
S Remove accumulated combustibles from
muffler area and cylinder area.
S 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
Unintentional sparking can result in
fire or electric shock.
Unintentional start-up can result in
entanglement, traumatic amputation,
or laceration.
BEFORE PERFORMING ADJUSTMENTS
OR REPAIRS
S Disconnect spark plug wire and keep it away
from spark plug.
S Disconnect battery at negative terminal (only
engines with electric start.)
S Do not strike the flywheel with a hammer or
hard object because the flywheel may later
shatter during operation.
S Do not tamper with governor spring, links or
other parts to increase engine speed.
S Use only correct tools.
WHEN TESTING FOR SPARK
S Use approved spark plug tester.
S Do not check for spark with spark plug
removed.
