SECTION 5: MAKING ADJUSTMENTS  
Drive Control  
When the drive control is released and in the  
disengaged “up” position, the cable should have very  
little slack. It should NOT be tight.  
Check the adjustment of the drive control as follows:  
1. With the drive control released, push the snow  
thrower gently forward. The unit should roll freely.  
2. Engage the drive control and gently attempt to push  
the snow thrower forward. The wheels should not  
turn. The unit should not roll freely.  
3. With the drive control released, move the shift lever  
back and forth between the R2 position and the F6  
position several times. There should be no  
resistance in the shift lever.  
If any of the above tests failed, the drive cable is in need  
of adjustment. refer to the figure at the right and  
proceed as follows:  
Figure 3  
Figure 4  
Figure 5  
Loosen the hex jam nut on the auger control cable  
“Z” fitting and rotate the coupling end of the cable  
downward to provide more slack or upward to take  
up slack. See Figure 3.  
Retighten the hex jam nut and repeat all three tests  
to verify proper adjustment has been achieved.  
Skid Shoes  
The space between the skid shoes and the ground can  
be adjusted. See Figure 4.  
For close snow removal on a smooth surface, raise  
skid shoes higher on the auger housing.  
Use a middle or lower position when the area to be  
cleared is uneven, such as a gravel driveway.  
CAUTION: Loose gravel can be picked up  
and thrown by the auger, causing injury to the  
operator and bystanders and/or damage to  
the snow thrower and surrounding property.  
Adjust skid shoes by loosening the four hex nuts  
(two on each side) and carriage bolts. Move skid  
shoes to desired position.  
Make certain the entire bottom surface of skid shoe  
is against the ground to avoid uneven wear on the  
skid shoes. Retighten nuts and bolts securely.  
Chute Bracket Adjustment  
If the spiral at the bottom of the chute directional control  
is not fully engaging with the chute assembly, the chute  
bracket can be adjusted. To do so, loosen the two nuts  
which secure the chute bracket and reposition it slightly  
before retightening the nuts. See Figure 5.

Tire Pressure  
Before operating, check tire pressure and reduce  
pressure to between 15 psi and 20 psi.  
NOTE: If the tire pressure is not equal in both tires, the  
unit may pull to one side or the other.  
Auger Control  
Refer to Auger Control Test on Page 11 to adjust the auger  
control.  
Chute Assembly  
The distance snow is thrown can be adjusted by  
changing the angle of the chute assembly. To do so,  
stop the engine by removing the ignition key and loosen  
the plastic wing knob found on the left side of the chute  
assembly. Pivot the chute upward or downward before  
re-tightening the wing knob. See Figure 6.

SECTION 7: OFF-SEASON STORAGE  
Drain carburetor by pressing upward on bowl drain,  
located below the carburetor cover.  
WARNING: Never store the machine or  
fuel container indoors where there is an open  
flame, spark or pilot light such as on a water  
heater, furnace, clothes dryer or other gas  
appliances.  
NOTE: Fuel stabilizers, such as STA-BIL®, are an  
acceptable alternative in minimizing the formation of  
fuel gum deposits during storage. Do not drain  
carburetor if using a fuel stabilizer.  
WARNING: Drain fuel into an approved  
container outdoors, away from open flame.  
Allow engine to cool. Extinguish cigarettes,  
cigars, pipes, and other sources of ignition  
prior to draining fuel. Fuel left in engine for  
extended period deteriorates and will cause  
serious starting problems.  
Wipe equipment with an oiled rag to prevent rust.  
Remove spark plug and pour one ounce of engine  
oil through spark plug hole into cylinder. Cover  
spark plug hole with rag. Crank engine several  
times to distribute oil. Replace spark plug.  
Follow the lubrication recommendations found in  
the Maintenance Section.  
If unit is to be stored over 30 days, prepare for storage  
as follows:  
Always store the snow thrower in a clean, dry area.  
When storing any type of power equipment in an  
unventilated or metal storage shed, care should be  
taken to rust proof the equipment. Using a light oil or  
silicone, coat the equipment, especially any chains,  
springs, bearings and cables.  
Remove gasoline from carburetor and fuel tank to  
prevent gum deposits from forming on these parts  
and causing possible malfunction of engine.  
Run engine until fuel tank is empty and engine  
stops due to lack of fuel.
