Ariens Sno-Thro 921012 - Manual (Page 27)

GB - 27
NOTE: Keep housing level by adjusting skid
shoes equally.
SHEAR BOLTS
IMPORTANT: Use only Ariens shear bolts for
replacement. Use of any other type of shear
bolt may result in severe damage to unit. See
SERVICE PARTS on page 37.
Occasionally a foreign object may enter the
auger/impeller housing and jam the auger,
breaking shear bolts (Figure 28) which
secure the auger to the shaft. This allows
auger to turn freely on the shaft which may
help prevent damage to gear drive.
For Replacement:
1. Align shear bolt holes in auger with
shear bolt holes in the shaft.
2. Drive shear bolt through hole (if shear
bolt was broken this will drive remaining
part from shaft).
3. Secure shear bolt with nut.
REMOTE WHEEL LOCK
(921012, 013, 020)
If remote wheel lock does not lock or unlock:
1. Place unit in service position (see
Service Position on page 24).
2. Loosen jam nuts on cable. Make sure
the bottom jam nut is loosened enough
to remove slack from cable (Figure 29).
3. Pull the cable adjuster to remove slack
between the cable adjuster and the
extension spring and hold the cable
adjuster in position while finger
tightening the top jam nut against the
bracket. Do not extend the spring or
engage the mechanism.
4. Tighten the bottom jam nut.
5. Check function of remote wheel lock. If
wheel lock does not function properly,
remove bottom cover to check cable
slack.
6. Repeat steps 2 – 4 while watching cable
to remove slack.
7. Check function of remote wheel lock. If
wheel lock does not function properly,
take the unit to Dealer for repairs.
