OPERATIONAL CONTROLS
Know how to stop the SNOW THROWER quickly in
preparation for possible emergency situations.
Forward and reverse motion is stopped by releasing
your grip on the TRACTION CLUTCH handle 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
handle 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.
SINGLE CONTROL FEATURE: ** If you continue
holding the TRACTiON CLUTCH handle down while
blowing snow, you can release the BLOWER
CLUTCH handle 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 handle stops motion and the
^NOTE: IF rotation continues after five seconds,
refer to the CLUTCH CABLE instructions for
readjustment. 4

STARTING & WARMUP
Whenever possible, push SNOW THROWER
outdocirs 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: Move control to FAST
position.
B. CHOKE: Refer to Engine Manual for priming
and/or choking details.
C. ENGINE IGNITION; On all units, insert key or
turn key to ON position.
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) E L E CTRIC STARTING; On units with plug-in
120 Volt electric start, connect the starter
cable to the engine starter system, insert the
three pronged 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 does not start after five
seconds of continuous cranking, release the
key or start button to prevent overheating of
the starting motor. Locate and correct cause of
starting ^ problem before repeating electric
starting attempt.
WARM-UP PERIOD; Allow brief warm-up
outside with clutches released to avoid stalling
cold engine. Reset Choke as instructed in
Engine Manual as the unit warms up.
OPERATION: Select desired traction speed by
adjusting DIRECTION CONTROL LEVER, depress
TRACTION CLUTCH handle and drive unit to area
to be cleared. Depress BLOWER CLUTCH handle
and proceed to blow snow. The THROTTLE
CONTROL should normally be in the FAST position
for best result under most conditions. CAUTION: If
clogging occurs, back unit away from snow bank,
release both CLUTCH handles and, as a further
precaution, stop the engine and remove spark plug
wire before clearing the snow from the housing
and/pr discharge chute.
BEFORE STOPPING; Move unit to cleared area,
release TRACTION CLUTCH handle and run up to
top speed with BLOWER CLUTCH HANDLE
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.

Section III - MAINTENANCE
LUBRICATION SERVICES
Refer to the Engine Manual for lubrication
requirements on the engine powering your SNOW
THROWER. Your SNOW THROWER unit has five
(5)grease fittings, two (2) on the augers, one (1) in
the gearbox housing and two (2) on the auger shaft
bearings as shown in Figure 3.1. Service these and
the other general lube points as follows:
AUGER LUBRICATION: ONCE EACH YEAR,
preferably at the end of the winter season, remove
the two (2) shear bolts, apply grease to the fittings,
then spin the auger to work the grease out along the
auger shaft. Continue greasing and spinning augers
until grease appears at both ends of each auger
tube. Reinstall shear bolts and nuts after servicing.
This procedure will prevent the auger shaft from
rusting to the auger tube. Refer to FIG. 3.1.
BEARING LUBE: ONCE EACH YEAR, apply one
or two shots of grease from gun to the bearing
grease fittings located at the ends of the auger
shaft, just inside blower housings. Refer to FIG. 3.1.
GENERAL LUBE POINTS: ONCE EACH YEAR, or
more often if rust hampers operation, spread a light
coating of grease on the chute crank worm and on
the underside of the gear ring at the base of the
discharge chute. Squirt oil from the oil can into the
gap between the inside of the discharge chute and
the outside of the discharge flange of the blower
housing. Crank chute back and forth while oiling to
spread lubrication evenly over both surfaces.
Although not absolutely necessary, you may want to
remove each wheel at the end of the season and
apply a coating of grease on the axle shafts. This
will help to prevent rust and allow the wheels to be
moved more easily from transport to traction mode
during the next season.
GEARBOX LUBRICATION: Grease the gearbox ONCE
EACH YEAR, or more often as required, with 5 shots of
SNAPPER "OO" grease. Refer to FiG. 3.1. "00" grease
is available from your SNAPPER Dealer in handy
squeeze containers.
CHUTE CRANK SERVICE (1422/1522/1722)
If the chute does not crank easily after being lubricated
as specified in the foregoing GENERAL LUB POINTS
sectbn, loosen the mounting nut and bolt on the crank
worm bracket as shown in Figure 3.2 and then pivot the
bracket slightly away from or toward the gear ring until
the chute cranks with minimum effort. Retighten the bolt
and nut after adjusting is completed.
CHUTE CRANK SERVICE (1524/1724)
If the chute does not crank easily after lubricating, as
specified under GENERAL LUB POINTS, loosen both
adjusting nuts on the outside of the crank worm bracket
as shown in Figure 3.3 and pivot the bracket slightly
away from or toward the gear ring until the chute cranks
with minimum effort. Retighten the inside nut first, then
jam the outside nut tight against the inside nut to lock at
the new setting.

Section III - MAINTENANCE
BELT SERVICE
Belts do not require attention at any specific
interval, but should be checked if performance
deteriorates. This could occur due to slippage of
worn or loose belts. Check and adjust tension of
clutch cables first as described in the CLUTCH
CABLE ADJUSTMENT section. If performance con¬
tinues to be poor, after clutch cable tension has
been corrected, then check belts. MAKE SURE
ENGINE IS STOPPED AND SPARK PLUG WIRE
DISCONNECTED before working on the belts.
CLUTCH CABLE ADJUSTMENT
If slippage is noted, check tension of both clutch
cables. When properly adjusted,the cables should
becorhpletely slack with clutch handle released and
tight when the handle is fully depressed. The
springs on both cables should deflect 3/8” when
the handle is depressed. To adjust, loosen nut on
cable connector, turn connector to shorten or
lengthen cable as needed to attain the 3/8" deflec¬
tion, turn nut tight against connector tube to lock at
correct setting. Refer to FIG. 3.5 and 3.6.
NOTE; Blower rotation should cease within five
seconds after clutch handle is released. If rotation
continues after five seconds,cable may be too tight.
If readjusting the cable does not correct the
stopping time, check to make sure the idler return
spring is connected and that the idler is properly
set. See your SNAPPER Dealer to have this
condition corrected.
BELT TENSION: Tension on the traction drive belt
is automatically maintained by an individual idler
spring. After removing the belt guard and bottom
cover, check to make sure this spring is intact and
properly installed. If the spring is properly
connected, check for excessively worn belts. Notice
the return spring on the idler for the Auger/Impeller
drive-this spring activates the brake. The idler
should always return to braking position! Tension of
the Auger/Impeller drive belt, which is on the 3/4 dia.
engine drive shaft, is adjusted by loosening and
repositioning the idler puley. To increase tension,
loosen the idler pulley retaining nut, hold the idler
arm and push the pulley tighter against the belt. See
Figure 3.4. RetIghten nut after repositioning and
check for proper clutching action with blower clutch
handle released. Tension of the traction belt on the
inside pulley is non-adjustable. Before reinstalling
belt guard, check to make sure the belt guide on each
side of the pulley is about 1/16" away from the out¬
side surface of the blower belt with clutch engaged.
Adjust the guide by loosening bolts and moving
guide.

SINGLE HANDLE CONTROL ADJUSTMENTS
(ON MODELS SO EQUIPPED)
If the clutch controls need readjusting, turn engine
off and disconnect spark plug wire! Reset as follows
(Refer to figure 3.8):
(A) Have an assistant temporarily hold the traction
clutch control down against the handle grip. The
edge of the cam lock must be aligned with adjust¬
ment line scribed on the cam lock bracket as shown.
To align, loosen the two fasteners holding the cable
guide support bracket and slide the bracket Inward
or outward as needed then retighten the fasteners.
(B) With the traction clutch held down, have assis¬
tant hold the blower clutch control against handle.
The ferrule (shown in the inset of figure 3.8) must be
located about 1/16" (.060" exact) above the hook of
the cam lock. To adjust, loosen the 3 fasteners on
the cam lock bracket and slide the bracket up or
down until the setting is correct, then retighten the 3
fasteners on the cam lock bracket. Release controls.

SKID SHOE ADJUSTMENT
The skid shoes should be lowered to raise the
blower housing to clear gravelled or rough surfaces.
If necessary, adjust up until almost even with the
edges of the housing, to effectively clear smooth
paved surfaces. Note that the skid shoes can be in¬
stalled upside down to track better over icy or hard¬
paced surfaces. To adjust the skid shoes, place a
wood block under the lower edge of the blower hous¬
ing. Loosen the retaining nuts and slide shoe up or
down to desired height. Retighten the nuts. Set both
skid shoes in the same position. Remove block. See
Figure 3.7.
