SAFETY RULES
Safe Operation Practices and Precautions
Product knowledge and careful operation is the best way
to prevent accidents. Read this section carefully before operating attachment system. All operators, no matter
how much experience they may have, should read this and other related manuals before operating attachment system. It is the owner’s legal obligation to instruct all operators in safe operation.
1. Know the controls and how to stop quickly. READ THIS OPERATORS MANUAL and instructions
furnished with your tractor..
2. Know your equipment and its limitations.
3. Never allow children to operate equipment. Never allow adults to operate equipment without proper instruction.
4. Keep the area of operation clear of all persons, particularly small children, and pets.
5. Become familiar with all controls of equipment and
how to stop tractor/engine quickly.
6. Pay special attention to, and observe all warning, caution and danger labels on attachmentsystem.
7. Do not allow passengers on tractor or attachment
system at any time.
8. Driver should never leave operator’s seat while equipment is running.
9. Remove objects (sticks, stones and any other debris) from area of operation that may be picked up and thrown.
IO. Operate equipment only during daylight or with
adequate artificial light.
il.
Wear long pants and safe, sturdy shoes. Do not wear
loose fitting clothing that could get caught in moving parts.
12. Always wear eye protection (safety glasses, fSCS shield, safety goggles, etc.) to protect from any flying
objects and ear protection (ear muffs, ear plug, etc.) to protect from excessive noise.
13. Only operate equipment when fully alert. Therefore,
never operate equipment while fatigued, under the influence of alcohol, medication or other substances.
14. Know how to stop engine. Be prepared for an emer­gency situation.
15. Avoid high pressure fluids. Escaping fluid under pressure can cause serious injury.
16. Never attempt to make adjustment or repair of any
kind while the tractor and/or attachments are in motion. Shut off engine, remove key and allow all motion to stop.
17. Open doors if tractor engine is run in garage or shed
-exhaust fumes are dangerous.
18. Follow the maintenance recommendations for Safe
operation. See “Maintenance” section.
19. Disengage all attachment clutches and shift into neutral before attempting to start the engine.
20. Disengage power to attachments and stop the engine before leaving the operator’s position.
21. Disengage power to attachments when transporting or

8. Never attempt to make any adjustments while the engine is running (except when specifically recom-
mended by manufacturer).
9. Let engine (motor) and machine adjust to outdoor temperatures before starting to clear snow.
10.
Always wear safety glasses or eye shields during
operation or while performing an adjustment or repair to protect eyes from foreign objects that may be thrown from the machine.
Il.
Cross gravel driveways, sidewalks, or roads with
extreme caution. Loose sand and rocks may be picked up and thrown. Before operating, adjust height of skid shoes (if equipped) to clear gravel or crushed
rock surfaces.
12. If discharge chute becomes clogged, stop tractor, disengage power take-off (PTO) by pulling PTO switch downward, shut off engine, remove key and

16. If the unit should start to vibrate abnormally, stop the
engine and check immediately for the cause. Vibration is generally a warning of trouble.
17. Stop the engine whenever you leave the operating
position, before unclogging the collector/impeller housing or discharge guide, and when making any repairs, adjustments, or inspections.

wire away from the plug to prevent accidental starting.
20. Do not run the engine indoors, except when starting the engine and for transporting the snowthrower in or

Do not attempt to clear steep slopes.
22. Never operate the snowthrower without proper guards, plates, or other safety protective devices in place.
23. Never operate the sures, automobiles, window wells, drop-offs, and the like without proper adjustment of the snow discharge angle. Keep children and pets away.
24. Do not overload the machine capacity by attempting
to clear snow at too fast a rate.
25. Never operate the machine at high transport speeds on slippery surfaces. Use care when backing.
26. Never direct discharge at bystanders or allow anyone in front of the unit.
27. Disengage power to the collector/impeller when the
snowthrower is transported or not in use.
28. Use only attachments and accessories approved by
the manufacturer of the snowthrower (such as wheel
weights, counterweights, cabs, and the like).
29. Never operate the snowthrower without good visibility
or light.
Safe Maintenance and Storage
1. Check shear bolts, engine mounting bolts, and other bolts at frequent intervals for proper tightness to be sure the equipment is in safe working condition.
2. Never store the tractor with fuel in the fuel tank inside
a building where ignition sources are present such as hot water and space heaters, clothes dryers, and the like. Allow the engine to cool before storing in any enclosure.
3. Always refer to Operator’s Manual for important
details if the snowthrower is to be stored for an extended period.
4. Maintain or replace safety and instruction labels, as
necessary.
5. Run the machine a few minutes after blowing snow to
prevent freeze-up of the collector/impeller.
Safely Transporting the Snowthrower
1. Always use a heavy-duty trailer to transport equip­ment, whether or not attachment system is mounted to tractor.
2. Be sure trailer has all necessary lights and signs
required by local, state, provincial or federal laws.
3. Make sure all equipment is securely fastened to trailer with straps, chains, cables, etc.

Tractor Preparation
1. Increase the front tire pressure to 20 PSI for use with snowthrower.
2. On tractors with Kohler Magnum engines, loosen the air cleaner cover wing nut, pull intake hose out of plenum hole and rotate cover slightly. For winter operation only, this allows warmer air to be taken in through the air cleaner. This is not necessary for Kohler Command engines.
Flow Reduction Washer
A washer is provided which must be added to the hydrau­lic valve. The purpose of the washer is to increase travel time when the snowthrower is lowered. This washer has an
i/2’
O.D. and a hole in the middle slightly smaller than
i/16” I.D.

Read safety precautions on pages 2-3 of this manual.
2. Prior to any snow falling, survey area to make sure that all objects are removed to prevent them from being picked up and thrown from the snowthrower
resulting in personal injury or property damage.
3. Make sure PTO shield turns freely on PTO shaft and guards are properly fastened.
4. Make sure oil level in auger gearbox and speed reduction gearbox is correct (oil level should be even
with check plugs). Refer to figures 14 & 15 on page
13.
5. Inspect for loose, missing, and worn parts.
6. Properly adjust discharge chute, discharge spout and skid shoes. Refer to following paragraphs and figures
11 and 12.

WARNING:
A
Before operating snowthrower, make sure to position discharge chute away from people, pets,
windows or other property which may be injured or
damaged by snow or other thrown objects.
Discharge Spout Adjustment
The spout can be adjusted by loosening the knob on the
left hand side and rotating spout up or down. Adjust the
spout for desired throwing distance and snow conditions
(depth and wetness).

1. Start the tractor engine. Using the tractor lift lever, raise the snowthrower to highest position. There
should be a slight clearance between back of hitch and tractor stops. This will prevent the hydraulic pump from working against stops when snowthrower is fully raised.To check, raise up on snowthrower hitch by hand. You should be able to raise up on the hitch one to two inches before upward movement is stopped by tractor.
2. See figure 13. To adjust, loosen the two nuts (A) using a i-1/8” open-end wrench. Using a
socket, turn the two bolts (B) in or out an equal amount until adjustment is correct. Turning bolts in
will raise the snowthrower snowthrower. Tighten the two nuts (A) when adjust-
ment is correct.
