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

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.

• 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 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

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

• 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

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.

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

• 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.

WARNING

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 from this chart that matches the starting

temperature anticipated before the next oil change.

Oil capacity is approximately 90 ml (3 oz).

°F

-20 0 20 40 60 80 100

°C

-30 -20 -10 0 10 20 30 40

CAUTION: 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.

* CAUTION: Synthetic oil must be used when operating engine under

40° F (4° C) or engine damage will occur.

** CAUTION: SAE 30 oil, if used below 50° F (10° C), will result in hard

starting and possible engine bore damage due to inadequate

lubrication.

Checking or Adding Oil

CAUTION:

To check oil, engine must be level,

with oil fill facing up. If not level, dipstick reading will not be accurate and could lead to

possible over/under filling of oil. This may lead to possible engine damage.

• Check oil level before starting the engine.

• Check oil level before every use.

• Keep oil level at FULL.

• DO NOT overfill, use oil measure cup for filling.

• Add only 15 ml

 (0.5 oz) to 30 ml  (1 oz) of oil at a time. Oil capacity is

approximately 90 ml (3 oz).
