Section II - MACHINE OPERATION
PRE-START CHECK & ADJUSTMENTS
A. ENGINE LUBE: Check level and add oil, if needed,
of weight and grade specified in the Engine Owner's
Manual.
B. FUEL SUPPLY: After making sure unit is safely
away from ignition-producing appliances, and in an
area where gasoline fumes can be dissipated, fill
fuel tank with gasoline specified in Engine Manual.
C. CHECK TIRES and bring pressure up to specifi¬
cations -12-15 psi without tire chains or 15-20 psi
with chains.
D. CHECK UNIT to make sure guards and shields are
in place and tight. Also check blower housing to
insure that it is free of all foreign objects.
E. RESET SKID SHOES to suit area to be cleared.
Lower skid shoes to provide greater clearance
over gravel, or raise the shoes for smooth, paved
surface. Refer to Figure 3.8, SKID SHOE ADJUST¬
MENT.
F. ADJUST DISCHARGE CHUTE to throw snow in
desired direction. Rotate crank handle until chute is
in position desired.
G. SET DEFLECTOR CAP to throw snow desired
distance. Loosen wing nut, push cap edge back
even with the chute to throw snow up to 30 feet
away, or pull cap all the way out to throw snow
only about three feet. Retighten wing nut after
repositioning cap. ALWAYS STOP ENGINE
before repositioning.
OPERATIONAL CONTROLS
Know how to stop the Snow Thrower quickly in prep¬
aration for possible emergency situations. Foward
and reverse motion is stopped by releasing your grip on
the Traction Clutch Lever on the left handle bar. See
Figure 2.1. The collector augers and impeller fan will
stop rotating within five seconds* after releasing the
Blower Clutch Lever on the right. Stop the engines on
all models by removing the ignition key. Other
operational controls are discussed where pertinent under
the following operating procedures.
FIGURE 2.1
'NOTE: If rotation continues after five seconds, refer to
the Clutch Cable Instructions for readjustment.
SINGLE CONTROL FEATURE:
(Model 17243 Only)
If you continue holding the Traction Clutch Lever down
while blowing snow, you can release the Blower Clutch
Lever without stopping the Blower. This feature frees
your right hand to turn the Chute Crank to discharge
snow in a new direction. Releasing the Traction Clutch
Lever stops motion and the blower.
STARTING & WARMUP
Whenever possible, push Snow Thrower outdoors before
starting. If the Unit must be started inside your garage,
for example, make sure doors are wide open to provide
maximum ventilation. Move the Unit outdoors as soon
as possible after starting. After performing the pre-start
checks and services described earlier, proceed as
follows:
A. THROTTLE CONTROL: Set throttle control at fastest
position.
B. CHOKE: Refer to Engine Manual for priming and/or
choking details.
C. ENGINE IGNITION: On all Units, insert key into
ignition.
D. 1 ROPE STARTING: On Manual Start Models, pull
starting rope out in smooth, steady motion until
engine starts. To prolong the life of the starter
rope, slowly guide the handle back to the engine
rather than allowing it to snap back.
D. 2 ELECTRIC STARTING: On Units with Plug-In
110 Volt Electric Start, connect the starter cable
to the engine starter system, insert the three-prong
plug into a grounded 110 volt power receptacle and
depress the starter button on the cable until engine
starts. Detach cable from receptacle and engine.
On Jump Start Equipped Models, refer to
instructions provided in kit.
NOTE: If engine fails to start after five seconds of
continuous cranking, pause for ten seconds and try for
five more seconds to start engine. Release start button
to prevent overheating of starting motor. Refer to Engine
Owner's Manual and follow steps explained therein. If
engine fails to start see your SNAPPER Dealer.
E.
WARM-UP PERIOD: Allow brief warm-up outside
with clutches released to avoid stalling cold engine.
Reset Choke as instructed in Engine Owner's Manual
as the Unit warms up.
OPERATION
Select desired traction speed by adjusting Speed
Control Lever, depress Traction Clutch Lever and
drive unit to area to be cleared. Depress Blower Clutch
Lever and proceed to blow snow. The Throttle Control
should be set at the fastest setting for best results.
CAUTION: If clogging occurs, back snow thrower away from
snow bank, release both Clutch Levers and, as a
further precaution, stop the engine and remove spark
plug wire before clearing the snow from the housing
and/or discharge chute.
BEFORE STOPPING
Move Unit to cleared area, release Traction Clutch
Lever and run up to top speed with Blower Clutch
Lever depressed to clear housing of slush and snow,
thus preventing freeze-up of the impeller upon restart¬
ing next time.
STOPPING PROCEDURE
On all Units, remove the key to stop engine and move
the Throttle Control to OFF or STOP.
