Slope Operations
Slopes are a major factor related to slip and fall accidents, which can result in severe injury. All
slopes require extra caution. If you feel uneasy on a slope, do not mow it.
DO:
Mow across the face of slopes; not up and down. Exercise extreme caution when
changing directions on slopes.
Always keep the mower below you when mowing on the slope.
Remove objects such as rocks, tree limbs, etc.
Watch for holes, ruts or bumps. Tall grass can hide obstacles.
(Figure 1)

DO NOT:
Do not mow near drop-offs, ditches or embankments. The operator could lose
footing or balance.
Do not push the mower up the slope.
Do not mow slopes that are steeper than 45°incline.
Do not mow on wet grass. Reduced footing could cause slipping.
(Figure 2)
Children
Tragic accidents can occur if the operator is not alert to the presence of children.
Children are often attracted to the mower. Never assume that children will remain where
you last saw them.
1. Keep children out of the mowing area and under the watchful care of a
responsible adult.
2. Be alert and turn mower off if children enter the area.
3. Before and while moving backwards, look behind and down for small
children.
4. Never allow children to operate the mower.
5. Use extra care when approaching blind corners, shrubs, trees or other objects
that may obscure vision.

Service
1. Use extra care in handling gasoline and other fuels. Gasoline is highly

Figure 4
3. Secure the throttle cable neatly behind the handles using black tie wraps. Use one tie wrap
for the upper handle and one tie wrap for the lower handle.
Preparing the Engine
IMPORTANT: The Engine is shipped without oil.
Fill the engine with oil prior to startup in order to avoid
serious damage to the engine.
Consult the engine manual for more
complete instructions regarding engine
maintenance and operation.
Filling the Crankcase with Oil
The crankcase holds 0.58 U.S. quarts (0.55 liters) of oil. Use only high-quality SAE 10W30
weight detergent oil that has the American Petroleum Institute (API) service classif ication SF,
SG, or equivalent. SAE 30 W oil is recommended for ambient temperatures exceeding 80
°F.
Before each use, ensure that the oil level is between the Lower and Upper limit marks on the
dipstick (Fig.5)
Figure 5

To add oil:
1. Move the lawn mower to a level surface.
2. Stop the engine and wait for the blade to stop.
3. Clean around the dipstick.
4. Remove the dipstick by rotating the cap.
5. Wipe the dipstick clean with a clean cloth.
6. Insert the dipstick into the f iller neck BUT DO NOT SCREW IT IN. Then remove the
dipstick and read the oil level. (Fig. 5)
7. If the oil level reading is below the Lower Limit mark on the dipstick, slowly pour only
enough oil into the f iller hole to raise the oil level to the Upper Limit mark on the dipstick.
Do not overf ill the crankcase with oil and run the engine; engine damage will result. Drain
the excess oil until the oil level on the dipstick is within the limit.
8. Insert the dipstick into the f iller neck and rotate the cap clockwise until it is tight.
Filling the Fuel Tank with Gasoline
•Use clean, fresh, lead-free gasoline with an octane rating of 86 or higher. Using unleaded
gasoline results in fewer combustion deposits and longer engine life.
•Do not use gasoline containing more than 5% methanol, 10% ethanol, or 15% MTBE. Using
fuels containing a higher percentage of these additives will damage the engine and void
manufacturer’s warranty.
•Do not use gasoline that is stale or has been stored since the last mowing season or longer.
Figure 6
To Fill the Tank:
1. Stop the engine and wait for the blade to stop.
2. Clean around the fuel tank (Fig 6)
3. Remove the cap from the tank.
4. Fill the fuel tank to the bottom of the fuel level limit in the neck of the fuel tank. Do not over
f ill.
5. Install the cap and wipe up any spilled gasoline.

Operating Tips
•Review the safety instructions and read this Manual carefully before operating the lawn
mower.
•Never mow on slopes with inclines exceeding 45°.
•Never attempt to mow by pushing the lawn mower up the slope.
•Keep the mower pointing down when mowing slopes.
•Always stay above the mower when mowing slopes.
•Walk across the slopes not up and down.
•Clear the area of sticks, stones, wire, branches and other debris that the blade could hit or
throw.
•Keep everyone, especially children and pets, away from the area of operation.
•Avoid striking trees, walls, curbs or other solid objects. Never deliberately mow over any
object.
•If the lawn mower strikes an object or starts to vibrate, immediately stop the engine,
disconnect the wire from the spark plug and examine the lawn mower for damage.
•Maintain sharp blades throughout the cutting season.
•Replace the blades when necessary with original Eastman Industries replacement blades.
•Mow only dry grass or leaves. Wet grass and leaves tend to clump on the yard and can cause
the lawn mower to plug or the engine to stall.
•Wet grass or leaves can cause serious injury if you slip and come in contact with the blades.
•Clean the underside of the lawn mower deck after each mowing. Keep the engine in good
running condition.
•Clean the air f ilter frequently. Mulching stirs up more clippings and dust which clogs the air
f ilter and reduces engine performance.
•Consult the Engine Operator’s Manual for more complete instructions regarding engine
maintenance and operation.
