Ariens PRM-10000 - Manual (Page 39)

SERVICE AND ADJUSTMENTS
1. ENGINE
Refer to engine instruction book and nameplate
on engine for maintenance instructions. If repairs or
service are needed for engine, see an Ariens dealer
or nearest authorized engine service station.
NOTE
Maximum engine RPM for all engines
used on equipment in this manual is
3600 RPM.
2. ATTACHING
a. Sno-Thro Attachment.
(1) Hook the notches in the lower portion of
the Sno-Thro Attachment frame over the rod
passing through the forward section of the tractor
frame.
(2) Tip the two sections together, being sure
the jaw clutch on the Sno-Thro Attachment is in
the OUT position (counterclockwise).
(3) Insert and tighten the two 3/8-inch whiz-
lock screws through the top of the tractor frame
and into the Sno-Thro Attachment.
b. Chute Control Rod.
(1) Fasten the chute control crank to the
tractor handle bar with the hardware provided.
Position the worm gear so that it meshes properly
with the chute. Fasten securely.
3. OPERATION
a. To start the Sno-Thro Attachment, start the
engine, placing the Sno-Thro clutch in the IN position
(clockwise) and engage the engine clutch on the
tractor.
b. To stop the Sno-Thro Attachment, disengage
the engine clutch on the tractor and place the
Sno-Thro clutch in the OUT position.
c. The tractor may be used to move the unit with
the Sno-Thro Attachment stopped by engaging the
tractor clutch and leaving the Sno-Thro clutch in the
OUT position.
4. RUNNERS
a. An adjustable runner is provided on each side
of the blower housing (Figure 2). Raising or lowering
these runners controls the distance the scraper blade
is held above the surface being cleared. Adjustment
is accomplished by loosening the two nuts on each of
the runners to the desired position and retightening
the nuts. When blowing snow off concrete or other
hard surfaces, these runners should be adjusted so
that they are approximately 1/8-inch below the
scraper blade. When blawing snow off gravel
driveways or other gravel areas, adjust the runners so
that they are 1-1/4-inches below the scraper blade.
b. In wet snow which packs easily, it may be

necessary to remove the runners or turn them upside
down so the scraper blade will scrape clean.
5. SCRAPER BLADE
A scraper blade (Figure 2) is provided along the
bottom edge of the blower housing. During
operation, this blade runs along the surface being
cleared, directing the snow into the rotor and insuring
a clean surface. After considerable usage, this blade
may wear and require replacement. The blade can be
replaced by removing the carriage bolts holding it to
the housing.
6. SHEAR BOLT REPLACEMENT
Occasionally a small object may enter the rotor
and become jammed in the blades. When this occurs,
the shear bolts, located on the shaft on which the
rotor is mounted, will break and allow the rotor to
turn freely on the shaft. Before blowing can be
continued, this shear bolt must be replaced. See
