8. Install the positive cable (rubber boot over end) to the
positive (+) terminal and the negative cable (black) to
the negative (–) terminal of the battery and secure them
with capscrews and nuts. Slide the rubber boot over the
positive terminal to prevent a possible short-out from
occurring (Fig. 2).
9. Lower the hood and secure the latches.
Checking the Engine Oil
The engine is shipped with 3 quarts of oil in the crankcase;
however, the oil level must be checked before and after the
engine is first started.
1. Position the machine on a level surface.
2. Unscrew the dipstick (Fig. 3) and wipe it with a clean
rag. Screw the dipstick into the filler neck and make
sure it is seated fully. Unscrew the dipstick out of the
filler neck and check the oil level. If the oil level is low,
add enough oil to raise the level to the FULL mark on
the dipstick.

1. Dipstick
Note: If the oil level is at the ADD mark on the dipstick,
add 1 quart of oil to raise the oil level to FULL. Do not
overfill.
3. Pour oil into the filler neck until the level is at the
FULL mark on the dipstick. The engine uses any
high-quality oil having the American Petroleum
Institute (APl) “service classification” SF or SG. The
recommended viscosity (weight) of oil to use is SAE
30.
Important The aerator operates at very high engine
loads, so check the oil level every 8 operating hours or
daily. A new engine may consume some oil until it is
broken in. Initially, change the oil after the first 25 hours of
operation; thereafter, under normal conditions, change the
oil and filter after every 100 hours of operation. Change the
oil more frequently when the engine is operated in
extremely dusty or dirty conditions.
Filling the Gas Tank
We recommend the use of fresh, clean, unleaded regular
grade gasoline. Unleaded gasoline burns cleaner, extends
engine life, and promotes good starting by reducing the
build-up of combustion chamber deposits.
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline
that spills.
• Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1 in.
(25 mm) below the bottom of the filler neck.
This empty space in the tank allows gasoline to
expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where gasoline
fumes may be ignited by a spark.
• Store gasoline in an approved container and
keep it out of the reach of children. Never buy
more than a 30-day supply of gasoline.
• Always place gasoline containers on the ground
away from your vehicle before filling.
• Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior
carpets or plastic truck bed liners may insulate
the container and slow the loss of any static
charge.
• When practical, remove gas-powered equipment
from the truck or trailer and refuel the
equipment with its wheels on the ground.
• If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a gasoline dispenser
nozzle.
• If a gasoline dispenser nozzle must be used, keep
the nozzle in contact with the rim of the fuel
tank or container opening at all times until
fueling is complete.
Note: Do not mix oil with the gasoline. Never use
methanol, gasoline containing methanol, gasohol, gasoline
additives, premium gasoline, or white gas because engine
and fuel system damage could result.
