CAREFUL TO GRADUALLY ENGAGE ATTACHMENT
2. To clear an area properly run the Sno-Thro in an
overlapping series of paths. For large areas start in
the middle and blow snow to each side so it
doesn't have to be moved more than once.
3. Snow should be discharged with the direction of
wind whenever possible. Do not blow snow any
higher than necessary.
4. Chemicals used to melt ice and snow may damage
the finish of your Sno-Thro. When possible, wipe
the Sno-Thro clean with a rag (automotive wiper
washer fluid may be applied) to remove residue.

MAIIMTEIMAIMCE
Ariens Company recommends that you have ad
justments made by your local Ariens dealer. He has the
tools. and know-how to properly perform these
maintenance adjustments which may be required to
keep the Sno-Thro operating at peak efficiency. The
Sno-Thro is equipped with the finest quality engine ob
tainable. However, should servicing be required, it can
be obtained from an Ariens dealer or an authorized
engine manufacturer's service station. Should you
decide to make adjustments on your Sno-Thro yourself,
Ariens recommends that you call your dealer for the
answers to any questions that might arise in perform
ing this work.
SHEAR BOLT REPLACEMENT - FIGURE 12
Occasionally an object may enter the collector and jam
the rakes. When this occurs, the shear bolts securing
the rakes to the shaft will break and allow the rake to
turn freely on the shaft preventing damage to the gear
drive. When this happens, turn off the engine, remove
wire from spark plug, remove the broken shear bolt and
Replace with a new ARIENS shear bolt. Use of any other
type of shear bolt may result in severe damage to the
machine. USE ONLY ARIENS SHEAR BOLTS FOR
REPLACEMENT. Lubricate rakeshaft according to in
structions in "LUBRICATION".
RUNNERS AND SCRAPER BLADE - FIGURES 2 & 12
The runners may be removed from the blower housing
and re-installed in upside-down position to reduce contact area and thus reduce tendency to ride up when
clearing hard-packed snow.
The scraper blade is adjustable so it may be lowered to
compensate for wear. See Figure 12 and page 12 il
lustration. Loosen locknuts securing scraper blade and
move it down to compensate for wear. Retighten
locknuts. If the blade is allowed to wear down too far
the blower housing may be damaged.
ATTACHMENT CLUTCH ADJUSTMENT - FIGURE 16
The Attachment Clutch is adjusted by connecting the
chain to the spring just below the attachment clutch
rod. Connect the spring to a chain link so the chain is
snug but so the attachment idler (Figure f) drops away
from the blower drive belt with the lever all the way up.
TRACTION CLUTCH ADJUSTMENT - FIGURE 3
A drive disc adjustment is provided to compensate for
wear on the friction wheel. If slippage occurs when the
traction clutch is engaged, perform the drive disc ad
justment. This adjustment is possible without removing
the bottom cover. "Lock in" the differential during this
procedure.
The runners on each side of the blower housing, and
the scraper blade, along the bottom of the housing, are
all adjustable to suit conditions. Raising or lowering the
runners controls the distance the scraper blade is held
above the surface being cleared. Runners are adjusted
by loosening the two nuts securing each runner. See
Figure 2. Move the runner to the desired position and
retighten the nuts. Be sure to adjust both runners to the
same height to keep blower housing level. Uneven run
ners make the machine difficult to steer and will result
in an uneven clearing job.
Adjustment of the runners is critical to good cleaning. If
the machine is to be used on a gravel surface lower the
runners so the blower will not pick up gravel. After the
remaining snow is packed down, the runners may be
raised for close scraping. On smooth concrete or
blacktopped surfaces, the runners may be raised so the
scraper blade rests on the surface and scrapes clean.
FIGURE 3
Adjust as follows: Place Speed Selector in First. Tip
machine forward on blower housing. Tighten the ad
justment nut while turning the wheels until the wheels
begin to drag. When wheels begin to drag, the clutch
lever should be engaged and released to realign clutch
linkage prior to adjustment. It may be necessary to
repeat this procedure until proper adjustment is obtain
ed. Turn nut back three turns. Wheels should then turn
easily.
CHUTE CRANK ADJUSTMENT - FIGURE 4
In the event the chute crank fails to rotate smoothly
loosen the nut securing the worm clevis to the bracket.
This hole In the bracket is slotted to permit adjustment.
Position the worm so it aligns with the teeth on
Discharge Chute and there is a little clearance between
worm and the gear teeth. Tighten the nut. Rotate the
discharge chute through its full travel to see that it
turns easlily. Readjust if required. Lubricate as describ
ed in "LUBRICATION" section. Tension on chute crank
