2.3. Rotating Flighting Safety
• KEEP AWAY from rotating flighting.
• DO NOT remove or modify flighting guards, doors, or covers.
Keep in good working order. Have replaced if damaged.
• DO NOT operate the auger without all guards, doors, and
covers in place.
• NEVER touch the flighting. Use a stick or other tool to
remove an obstruction or clean out.
• Shut off and lock out power to adjust, service, or clean.
2.4. Rotating Parts Safety
• Keep body, hair, and clothing away from rotating pulleys,
belts, chains, and sprockets.
• Do not operate with any guard removed or modified. Keep
guards in good working order.
• Shut off and remove key or lock out power source before
inspecting or servicing machine.
2.5. Hand Winch Safety
When Equipped:
• Inspect lift cable before using. Replace if frayed or damaged. Make sure lift cable is seated
properly in cable sheaves and cable clamps are secure.
• Tighten brake lock by turning winch handle clockwise at least two clicks after lowering the
auger.
• Lower the auger fully before towing, then rotate winch handle until cable has light tension.
• Do not lubricate winch brake discs.
2.6. Drives and Lockout Safety
Inspect the power source(s) before using and know how to shut down in an emergency.
Whenever you service or adjust your equipment, make sure you shut down the power
source and unplug or remove the key (as applicable) to prevent inadvertent start-up and
hazardous energy release. Know the procedure(s) that applies to your equipment from the
following power source(s). Ensure that all personnel are clear before turning on power to
equipment.

2.6.1 Gas Engine Safety
Power Source
• Keep guards in place and secure.
• Properly ventilate surrounding area.
• Never fill the fuel tank with the engine running, while
smoking, or near an open flame. Always shut down and allow
engine to cool before filling with fuel.
• Never overfill the tank or spill fuel. If fuel is spilled, clean it
up immediately.
• Be sure to use the correct type and grade of fuel. Ground the
fuel funnel or nozzle against the filler neck to prevent sparks
that could ignite fuel vapors.
• Be sure to replace the fuel fill cap when you are done.
Lockout
• For engines with an electric start, remove the ignition key,
the spark plug wire, or the spark plug.
• For engines with a rope or crank start, remove the spark plug
wire or the spark plug.
2.6.2 Electric Motor Safety
Power Source
• Electric motors and controls shall be installed and serviced by
a qualified electrician and must meet all local codes and
standards.
• A magnetic starter should be used to protect your motor.
• You must have a manual reset button.
• Reset and motor starting controls must be located so that the
operator has full view of the entire operation.
• Locate main power disconnect switch within reach from
ground level to permit ready access in case of an emergency.
• Motor must be properly grounded.
• Guards must be in place and secure.
• Ensure electrical wiring and cords remain in good condition;
replace if necessary.
• Use a totally enclosed electric motor if operating in
extremely dusty conditions.
SERVICE DISCONNECT
ON
OFF
Lockout
• The main power disconnect switch should be in the locked position during shutdown or
whenever maintenance is performed.
• If reset is required, disconnect all power before resetting motor.

2.6.3 PTO Driveline Safety
Drive
• Keep body, hair, and clothing away from rotating PTO
driveline.
• Make certain the driveline shields telescope and rotate freely
on driveline before attaching.
• Make certain the driveline is securely attached at both ends.
• Do not operate auger unless all driveline, tractor, and
equipment shields are in place and in good working order.
• Do not exceed the specified operating speed.
• Keep universal joint angles small and equal. Do not exceed
maximum recommended length for PTO driveline.
• Engage tractor park brake and/or chock wheels.
Lockout
• Position all controls in neutral, shut off tractor’s engine, and remove key from tractor.
• If removing key is impossible, remove PTO driveline from tractor.

2.6.4 Hydraulic Power Safety
Power Source
• Refer to the rules and regulations applicable to the power
source operating your hydraulic drive.
• Do not connect or disconnect hydraulic lines while system is
under pressure.
• Keep all hydraulic lines away from moving parts and pinch
points.
• Escaping hydraulic fluid under pressure will cause serious
injury if it penetrates the skin surface (serious infection or
toxic reaction can develop). See a doctor immediately if
injured.
• Use metal or wood as a backstop when searching for
hydraulic leaks and wear proper hand and eye protection.
• Check all hydraulic components are tight and in good
condition. Replace any worn, cut, abraded, flattened, or
crimped hoses.
• Clean the connections before connecting to equipment.
• Do not attempt any makeshift repairs to the hydraulic fittings
or hoses with tape, clamps, or adhesive. The hydraulic
system operates under extremely high pressure; such repairs
will fail suddenly and create a hazardous and unsafe
condition.
Lockout
• Always place all hydraulic controls in neutral and relieve
system pressure before disconnecting or working on
hydraulic system.

2.7. Tire Safety
Failure to follow proper procedures when mounting a tire on a
wheel or rim can produce an explosion that may result in
serious injury or death.
• DO NOT attempt to mount a tire unless you have the proper
equipment and experience to do the job.
• Have a qualified tire dealer or repair service perform
required tire maintenance.
• When replacing worn tires, make sure they meet the original
tire specifications. Never undersize the replacement tire.
• DO NOT weld to the tire rim with the tire mounted on the
rim. This action may cause an explosion which could result in
serious injury or death.
• Inflate tires to the manufacturer’s recommended pressure.
• Tires should not be operated at speeds higher than their
rated speed.
• Keep wheel lug nuts tightened to manufacturer’s
recommendations.
• Never reinflate a tire that has been run flat or seriously
under-inflated without removing the tire from the wheel.
Have the tire and wheel closely inspected for damage before
remounting.
2.8. Battery Safety
• Wear safety glasses and protective gloves when working near
batteries.
• Make certain the battery or terminal covers are in place and
in good working order.
• Keep all sparks and flames away from batteries; gas given off
by electrolyte is explosive.
• Avoid contact with battery electrolyte. Wash off any spilled
electrolyte immediately.
• Do not tip batteries more than 45° to avoid electrolyte loss.
• To avoid injury from sparks or short circuits, disconnect
battery ground cable before servicing any part of an electrical
system.
