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.

engine. Your engine will have one of the following types.
ReadyStart System: This features a temperature controlled automatic choke. It
 ®
does not have a manual choke or a primer.
Primer System: This features a red primer to be used for starting in cool

temperatures. It does not have a manual choke.
Choke System: This features a choke to be used for starting in cool temperatures.

Some models will have a separate choke lever while others will have a combination
choke/throttle lever. This type does not have a primer.
To start your engine, follow the instructions for your type of starting system.
Note: Equipment may have remote controls. See the equipment manual for location and
operation of remote controls.
