CARBURETORADJUSTMENT
&
WARNING:
If any adjustments
are made
to the engine while the engine is running
(e.g. carburetor),
keep clear of all moving
parts. Be careful of heated surfaces and
muffler.
Minor carburetor adjustment may be required to com-
pensate for differences
in fuel, temperature,
altitude
and load.
Refer to the separate
engine manual
packed with
your unit for carburetor adjustment information.
DRIVE WHEELS
The wheels may be adjusted for two different meth-
ods of operation. The adjustment is made by placing
the klick pins in one of two different holes on the right
side of the unit. See figure 15.
1. One Wheel DrivingmPlace
klick pin in the out-
side axle hole on the right side. This position
gives power drive to the left wheel only, making
the unit easier to maneuver.
,
Both Wheels Driving--Place
klick pin in the hole
in the hub next to the rim on the right side. This
position is good for heavy snow as there is power
drive in both wheels.
IMPORTANT:
Keep all grease
and oil off of the
friction wheel and drive plate.
Shifting Mechanism
Lubricate the shifting mechanism and pivot points on
the shift rod with engine oil at least once a season or
after every 25 hours of operation,
Traction Drive/Auger Clutch Lock
The cams on the ends of the control rods which inter-
lock the traction drive and auger drive clutches must
be lubricated at least once a season or every twenty-
five hours of operation.
The cams can be accessed
beneath the handle panel. Refer to page 16, refer-
ence 39. Use a multi-purpose automotive grease.
Gear Case
The gear case is lubricated with grease at the factory
and does not require checking.
If disassembled
for
any reason, lubricate with 2 ounces of Shell Alvania
grease, part number 737-0168.
Bearings
Lubricate the auger and wheel bearings once a sea-
son with light oil.
AUGERS
The augers are secured to the spiral shaft with two
hex bolts and hex lock nuts. See figure 16. If you hit a
foreign
object
or ice jam,
the snow
thrower
is
designed so that the hex bolts will shear.
If the augers will not turn, check to see if the hex bolts
have sheared. Two replacement
hex bolts and hex
lock nuts have been provided with the snow thrower.
For future use, order part number 710-0890 (hex bolt
5/16-18 x 1.5" long) and 712-0429 (hex insert lock nut
5/16-18 thread).
