Other Tips
• Always use a firm grip when holding the unit.
• To reduce the risk of hearing loss, hearing protection is required.
• Operate power equipment only at reasonable hours when people might
not be disturbed. Comply with times listed in local ordinances. Usual
recommendations are 9:00 am to 5:00 pm, Monday through Saturday.
• To reduce noise levels, operate the unit at the lowest possible speed to
do the job.
• Use rakes and brooms to loosen debris before blowing.
• Watch for bystanders, open windows or cars; blow debris safely away.
• Use the curved tube extension so the unit can work closer to the ground.
• Clean up after using blowers and other equipment. Dispose of debris
appropriately.

CHECKING THE OIL LEVEL
The importance of checking and
maintaining the proper oil level in the
crankcase cannot be overemphasized.
Check oil before each use:
1. Stop the engine and allow oil to drain
into the crankcase.
2. Place the engine on a level surface.
3. Clean the area around the oil plug
before removing it. Keep dirt, grass
clippings, and other debris out of the
engine.
4. Remove the oil plug (Fig. 14).
5. Look into the oil fill hole (use a
flashlight if needed). The oil should
be just touching the innermost
thread (Fig. 13).
6. If the oil level is not touching the
innermost thread on the oil fill hole,
add a small amount of oil to the oil
fill hole and recheck (Fig. 13). Repeat
this procedure until the oil level
reaches the innermost thread on the
oil fill hole.
NOTE: Do not overfill the unit.
NOTE: Make sure the O-ring is in place
on the oil plug when checking and
changing the oil (Fig. 14).
CHANGING THE OIL
Change the oil while the engine is still
warm. The oil will flow freely and carry
away more impurities.
1. Remove the oil fill plug.
2. Pour the oil out of the oil fill hole and
into a container by tipping the unit
to a vertical position (Fig. 15). Allow
ample time for complete drainage.
3. Wipe up any oil residue on the
unit and clean up any oil that may
have spilled. Dispose of the oil
according to federal, state and local
regulations.
4. Refill the crankcase with 2.03 fluid
ounce (60 ml) of SAE 30 SF, SG, SH
oil (Fig. 17).
NOTE: Use the bottle and spout saved
from initial use to measure the
correct amount of oil. The fill line
on the bottle's label measures
approximately 2.03 ounces (60 ml)
(Fig. 16).
5. Check the level, See Checking the
0il Level.
6. Once full, replace the oil plug.

Failure to maintain the air filter will VOID
the warranty.
1. To open the air filter cover, push
the tab on the left side of the cover
inward and pull the air filter cover
slightly out and to the right (Fig. 18).
2. Remove the air filter (Fig. 18).
3. Wash the filter in detergent and
water. Making sure to rinse the filter Air Filter
thoroughly and allow it to dry.
4. Lightly coat the filter with clean SAE
30 motor oil.
5. Squeeze the filter to spread and remove excess oil.
6. Replace the filter.
NOTE: Operating the unit without the air filter will VOID the warranty.
7. To reinstall the air filter cover, position the hooks on the right side of the
air filter cover into the slots at the right side of the back plate (Fig. 18).
8. Swing the cover to the left and press closed so the air filter cover tab
snaps into the slot on the back plate (Fig. 18).
IDLE SPEED ADJUSTMENT
The idle speed of the engine is adjustable. An idle adjustment screw is
between the air filter cover and the engine starter housing (Fig. 19).
NOTE: Careless adjustments can seriously damage to the unit. A Sears or
other qualified service dealer should make carburetor adjustments.
If, after checking the fuel and cleaning the air filter, the engine still will not
idle, adjust the idle speed screw as follows:
1. Start the engine and warm up
according to the Starting/Stopping
Instructions.
2. Release the trigger and let the engine
idle. If the engine stops, insert a
small Phillips screwdriver in between
the Air Filter Cover and the Engine
Cover (Fig. 19). Turn the idle speed
screw 1/8 of a turn clockwise at a
time until the engine idles smoothly.
Checking the fuel, cleaning the air filter,
ldle A2JrUeStwm e nt
Fig. 19
and adjusting the idle speed should solve most engine problems. If not and
all of the following are true:
• the engine will not idle
• the engine hesitates or stalls on acceleration
• there is a loss of engine power
take the unit to a Sears or other qualified service dealer.
ROCKER ARM CLEARANCE
_, WARNING:
To avoid serious personal injury, always turn the
unit off and allow it to cool before cleaning or maintaining it.
This adjustment requires disassembly
of the engine. If you feel unsure or
unqualified to perform this, take the
unit to a Sears or other qualified service
dealer.
• The engine must be cold when
checking or adjusting the rocker arm
clearance.
• This task should be performed
inside, in a clean, dust free area.
1. Remove the 8 engine cover screws
with the appropriate tool (Fig. 20),
then remove the cover.
NOTE: Make sure to store the screws so
that they can be reinstalled into their
original holes.
2. Disconnect the spark plug wire.
3. Clean dirt from around the spark
plug and rocker arm cover.
Remove the spark plug from the
cylinder by turning a 5/8 in. socket
counterclockwise.

• Both rocker arms move freely, and both valves are closed.
If these statements are not true, repeat this step.
6. Slide the feeler gauge between the rocker arm and the valve return
spring. Measure the clearance between the valve stem and rocker arm
(Fig. 22). Measure both the intake and exhaust valves.
The recommended clearance for both intake and exhaust is .003 - .006 in.
(.076 - 0.152 mm). Use a standard automotive .005 in. (0.127 mm) feeler
gauge. The feeler gauge should slide between the rocker arm and valve stem
with a slight amount of resistance, without binding (Fig. 22).
