Operating Safety
Power equipment is only as safe as the operator. If it is misused,
or not properly maintained, it can be dangerous! Remember,
you are responsible for your safety and that of those around
you.
Use common sense, and think through what you are doing. If
you are not sure that the task you are about to perform can be
safely done with the equipment you have chosen, ask a
professional: contact your local authorized dealer.
Read the Manual
The operator’s manual contains important safety information
you need to be aware of BEFORE you operate your unit as well
as DURING operation.
Safe operating techniques, an explanation of the product’s
features and controls, and maintenance information is included
to help you get the most out of your equipment investment.
Be sure to completely read the Safety Rules and Information
found on the following pages. Also completely read the
Operation section.
Children
Tragic accidents can occur with children. Do not allow them
anywhere near the area of operation. Children are often attracted
to the unit and mowing activity. Never assume that children will
remain where you last saw them. If there is a risk that children
may enter the area where you are mowing, have another
responsible adult watch them.
Slope Operation
3.5 ft
(1,5 m)
20.0 ft
(6,0 m)
You could be seriously injured or even killed if you use this unit
on too steep an incline. Using the unit on a slope that is too
steep or where you don’t have adequate footing or traction can
cause you to lose control or slip and fall.
You should not operate on inclines with a slope greater than 10
degrees, which is a 3.5 ft (1,5 m) rise over 20.0 ft (6,0 m).
Always mow across slopes, never up and down.
Also note that the surface you are mowing can greatly impact
control. Wet grass or leaves can seriously affect your footing
and traction on a slope.
If you feel about operating the unit on an incline, don’t do it. It’s
not worth the risk.
Moving Parts
This equipment has moving parts that can injure you or someone
else. However, if you stand behind the handle properly and
follow all the rules in this book, the unit is safe to operate.
The mower has a spinning mower blade that can amputate
hands and feet. Do not allow anyone near the equipment while

Prepare the mower for end-of-season storage as follows:
1. Disconnect the spark plug wire and secure away from the
spark plug.
2. Drain the fuel tank and let the engine run until all fuel is out
of the carburetor.
Note:
If using a fuel stabilizer, there is no need to drain the fuel
tank. See
Fuel System
.

use a damp cloth to wipe down the unit.
4. Tilt the mower up on its rear wheels and inspect the
underside of the deck. (Do not tilt the mower with the spark
plug or carburetor down.) Scrape away stubborn
accumulation of grass with a putty knife and/or wire brush.
5. Lubricate all exposed metal with a light coating of oil to
prevent corrosion.
6. Carefully fold the handles, flexing the control cables to
prevent cable damage.
7. Store the mower in a shed or other dry area, protected from
weather.
Fuel System
Fuel can become stale when stored over 30 days. Stale fuel
causes acid and gum deposits to form in the fuel system or on
essential carburetor parts. To keep fuel fresh, use Briggs &
Stratton Advanced Formula Fuel Treatment & Stabilizer,
available wherever Briggs & Stratton genuine service parts are
sold.
There is no need to drain gasoline from the engine if a fuel
stabilizer is added according to instructions. Run the engine for
two (2) minutes to circulate the stabilizer throughout the fuel
system before storage.
If gasoline in the engine has not been treated with a fuel
stabilizer, it must be drained into an approved container. Run
the engine until it stops from lack of fuel. The use of a fuel
stabilizer in the storage container is recommended to maintain
freshness.
