Maintenance - Briggs & Stratton 100000 Operator's Manual

WARNING
POISONOUS GAS HAZARD. Engine exhaust contains carbon monoxide, a
poisonous gas that could kill you in minutes. You CANNOT see it, smell it,
or taste it. Even if you do not smell exhaust fumes, you could still be
exposed to carbon monoxide gas. If you start to feel sick, dizzy, or weak
while using this product, shut it off and get to fresh air RIGHT AWAY. See a
doctor. You may have carbon monoxide poisoning.
Operate this product ONLY outside far away from windows, doors and vents to

reduce the risk of carbon monoxide gas from accumulating and potentially being
drawn towards occupied spaces.
Install battery-operated carbon monoxide alarms or plug-in carbon monoxide

alarms with battery back‐up according to the manufacturer's instructions. Smoke
alarms cannot detect carbon monoxide gas.
DO NOT run this product inside homes, garages, basements, crawlspaces,

sheds, or other partially‐enclosed spaces even if using fans or opening doors
and windows for ventilation. Carbon monoxide can quickly build up in these
spaces and can linger for hours, even after this product has shut off.
ALWAYS place this product downwind and point the engine exhaust away from

occupied spaces.
NOTICE: This engine was shipped from Briggs & Stratton without oil. Before you start
the engine, make sure you add oil according to the instructions in this manual. If you
start the engine without oil, it will be damaged beyond repair and will not be covered
under warranty.
Note: Equipment may have remote controls. See the equipment manual for location and
operation of remote controls.

How To Check / Add Oil
1. Check the oil level. See the
2. Make sure equipment drive controls, if equipped, are disengaged.
3. Move the throttle control (C, Figure 4), if equipped, to the fast position. Operate the
engine in the fast position.
4. If the product is equipped with an engine stop lever (D, Figure 5), hold the engine
stop lever against the handle.
5. Rewind Start: Firmly hold the starter cord handle (E). Pull the starter cord handle
slowly until resistance is felt, then pull rapidly (Figure 4).
WARNING:
Rapid retraction of the starter cord (kickback) will pull your
hand and arm toward the engine faster than you can let go. Broken bones, fractures,
bruises or sprains could result. When starting engine, pull the starter cord slowly until
resistance is felt and then pull rapidly to avoid kickback.
6. Electric Start: Activate the electric start switch .
NOTICE: To extend the life of the starter, use short starting cycles (five seconds
maximum). Wait one minute between starting cycles.
Note: If the engine does not start after repeated attempts, contact your local dealer or go
to BRIGGSandSTRATTON.COM or call 1-800-233-3723 (in USA).

Maintenance

NOTICE: If the engine is tipped during maintenance, the fuel tank must be empty and the
spark plug side must be up. If the fuel tank is not empty and if the engine is tipped in any
other direction, it may be difficult to start due to oil or gasoline contaminating the air filter
and / or the spark plug.
WARNING:
When performing maintenance that requires the unit to be
tipped, the fuel tank must be empty or fuel can leak out and result in a fire or
explosion.

We recommend that you see any Briggs & Stratton Authorized Dealer for all
maintenance and service of the engine and engine parts.
NOTICE: All the components used to build this engine must remain in place for proper
operation.
Emissions Control
Maintenance, replacement, or repair of the emissions control devices and systems may
be performed by any off‐road engine repair establishment or individual. However, to
obtain "no charge" emissions control service, the work must be performed by a factory
authorized dealer. See the Emissions Warranty.
WARNING
Unintentional sparking can result in fire or electric shock.
Unintentional start‐up can result in entanglement, traumatic amputation, or
laceration.
Fire hazard
Before performing adjustments or repairs:
Disconnect the spark plug wire and keep it away from the spark plug.

Disconnect battery at negative terminal (only engines with electric start.)

Use only correct tools.

Do not tamper with governor spring, links or other parts to increase engine

speed.
Replacement parts must be of the same design and installed in the same

position as the original parts. Other parts may not perform as well, may damage
the unit, and may result in injury.
Do not strike the flywheel with a hammer or hard object because the flywheel

may later shatter during operation.
When testing for spark:
Use approved spark plug tester.

Do not check for spark with spark plug removed.

Carburetor And Engine Speed Adjustment
Never make adjustments to the carburetor or engine speed. The carburetor was set at
the factory to operate efficiently under most conditions. Do not tamper with the governor
spring, linkages, or other parts to change the engine speed. If any adjustments are
required contact a Briggs & Stratton Authorized Service Center for service.
NOTICE: The equipment manufacturer specifies the maximum speed for the engine as
installed on the equipment. Do not exceed this speed. If you are unsure what the
equipment maximum speed is, or what the engine speed is set to from the factory,
contact a Briggs & Stratton Authorized Service Center for assistance. For safe and
proper operation of the equipment, the engine speed should be adjusted only by a
qualified service technician.
