Operation
Pre-Starting
j. WARNING: Wear adequate winter
/V outer garments, footwear which will
improve footing on slippery surfaces
and eye protection such as safety
goggles. DO NOT wear loose
clothing or scarves that may get
caught in rotating parts of unit.
(Red) gasoline container.
Check fuel supply. Fill gasoline tank with good
grade of fresh unleaded gasoline (leaded if

gasahol or mix gasoline with oil.
NOTE: To prevent foreign particles from entering
tank while filling; wipe snow, dust, dirt and debris
from around cap before removing.
A CAUTION: Make sure all hardware is
tight, all safety devices in place and
all adjustments correct.
IMPORTANT: Check impeller to be sure it is not
frozen by removing spark plug wife, engaging
attachment clutch and pulling rewind starter. If
impeller is frozen, move Sno-Thro to a heated
area and thaw to prevent possible damage to
unit.
NOTE: This product is equipped with an internal
combustion type engine. DO NOT use unit on or
near any unimproved, forest-covered or brush
covered land unless exhaust system is equipped
with a spark arrester meeting applicable local,
state or federal laws. A spark arrester, if it is
used, must be maintained in effective working
order by operator.
Check that engine crankcase oil is full using
dipstick. Refer to Lubrication and Maintenance
Section.
Starting
CAUTION: DO NOT attempt to start
your engine at this time. Thoroughly
read this entire Owner’s Manual and
engine manufacturers operating
instructions first.
Function of Clutches
CAUTION: Check clutch
disengagement before each use. If
clutches do not function properly,
adjust or repair per instructions in
Adjustments Section of this manual
before operating unit.
On units with interlock, check interlock by
pressing down on clutch levers (engaging both
clutches). Remove hand from attachment clutch
lever, attachment clutch should remain engaged
until traction clutch lever is released then both
clutches must disengage.
Differential Lock
On units with differential, to engage differential
lock pull and turn knob to "LOCKED" position
and release (it will snap in when positioned
correctly). To resume differential action, for
transport, etc., pull and turn knob to
"UNLOCKED" and release.
With differential locked, power is applied equally
to both wheels. Engage differential lock (located
in left wheel hub) for best traction when throwing
snow.
Runners
NOTE: Try out each control without running
engine to see how they work and what they do.
Fuel
yk CAUTION: Adjust auger/impeller
housing (scraper blade) height to
clear gravel or crushed rock
surfaces.
- WARNING: Gasoline is highly
^ flammable and must be handled with
care. Never fill tank when the engine
is running or hot from operation. DO
NOT allow open flame, matches or
smoking in area. DO NOT overfill.
Wipe up any spills. Use approved
Runners should be adjusted as conditions
require. Raising or lowering runners controls
distance scraper blade (auger/impeller housing)
is held above surface being cleared.

Operation (Continued)
When operating machine on gravel surface,
lower runners so that housing will not pick up
gravel. On concrete, blacktopped or packed
snow surfaces raise runners so that scraper
blade scrapes clean. To reduce tendency of
housing to ride up over heavy wet or hard-
packed snow, remove runners and re-install with
their narrow edge down.
Position Sno-Thro on a flat level surface. Adjust
runners by inserting a spacer of desired
thickness under center of scraper blade, loosen
hardware, slide runners to flat surface and
retighten hardware.
NOTE: Above method keeps housing level by
adjusting runners equally. Uneven runners make
machine difficult to steer and results in uneven
clearing.
Chute Deflector
Position Deflector at desired height. DO NOT
throw snow any higher than necessary. (Remote
control, turn knob 1/4 turn to unlock, push in or
pull out to desired height and turn knob to lock
deflector in position). _ __ — -
