2. Fill fuel tank with fresh gasoline (unless a fuel stabilizer was used).
3. Check to be sure engine fins are clean and air flow is
unobstructed.
4. Start the engine outdoors. Allow the engine to warn
up before blowing snow.
Do not operate on gravel or crushed rock surfaces.
Avoid picking up this type of material with auger since
damage to unit could result and particles can be discharged with considerable force that could cause serious
injury.
Always be alert to hidden hazards that might be struck
by the auger. Should a foreign object be struck by the
auger, immediately stop the engine and inspect machine
for any damage. Repair damage before continuing operation.
5. Check the operation of all the controls.

LUBRICATION
Note: The drive pulley end of auger shaft is supported by
a sealed ball bearing and requires no lubrication. The
ball bearing on other end of auger shaft is also sealed,
and will not require lubrication.
Lightly Oil
• A few drops of oil should be placed on wheel
hubs occasionally to keep wheels turning
freely.
Figure 9. Lubrication points
• Apply oil to pivot points of auger control periodically, wiping off any excess oil.
• A couple of drops of light machine oil applied to
upper end of auger control cable will assure free
movement of cable through outside casing. Wipe off
any excess oil.
Pivot Point
• Remove belt cover and lightly apply oil to the pivot
point for idler pulley arm. BE CAREFUL NOT TO
GET OIL ON BELT OR PULLEYS.
Grease

AUGER CONTROL
CABLE ADJUSTMENT
Adjusting the Cable
The length of the auger control cable is adjustable.
However, it will seldom be necessary to change the
cable length since the operating tension on the drive belt
is maintained by the spring on the end of the cable.
2. Locate and loosen the lower locknut securing the
auger control cable (shown in Figure 14).
1. Remove the engine cover.
3. To change the slack in the cable, turn the upper locknut slightly just until the slack between the spring
and the exposed cable has been eliminated.
If the auger turns too slowly under heavy load or
momentary squealing of drive belt is heard when entering heavy snow, pressure applied to drive belt by idler
pulley must be increased by reducing the slack in the
cable.
4. Tighten the lower locknut.
5. Test the units to make certain that the cable has
been adjusted properly.
If the auger continues to turn when the auger control
is released, the cable is too tight. The pressure applied
to the drive belt must be eliminated by increasing the
amount of slack to the cable adjustment.
WARNING
Use extreme care when making adjustments that
require engine to be running. Keep hands, feet,
hair and loose fitting clothing away from moving
parts.
WARNING
Make certain the cable is not placing and tension
on the spring. If the cable places tension on the
spring, the auger may turn when the control has
not been engaged.
Testing the Auger Control Cable
Start the snowthrower engine and pull back on auger
control to operate auger. Release auger control and
check to be sure auger stops turning.
Checking the Adjustment.
If auger continues to turn after auger control is
released, cable is too tight and will have to be adjusted to make it longer. Cable must be slightly slack
when auger control is released (away from handle).
1. Remove the cover. (See page 14.)
2. Measure the spring while the auger control on the
handle is disengaged. Record this measurement.
3. Pull the auger control against the handle and again
measure the spring. Record this measurement.
CARBURETOR ADJUSTMENT
4. Compare the two measurements. The measurement
obtained with the spring extended should be 7/16
inch (11 mm) greater than with the spring at rest.
The carburetor is properly calibrated and preset at the
factory for efficient cold weather operation. There are no
adjustments.
