Most farming operations today use skid steer loaders for a
variety of purposes. This versatile piece of equipment is
used inside farm buildings as well as outside. Accidents with
skid steer loaders can occur when conditions have changed
due to weather or when untrained individuals operate them.
Recognize the dangers
The first step to avoiding danger while operating a skid steer
loader is hazard recognition. Read, understand, and follow
instructions in the manufacturer's operating manual and safety
decals on the loader. Identify specific hazards associated
with the equipment.
Carefully evaluate each task you wish to perform before starting
work. For example, a skid steer loader bucket is a poor choice
for a human lift because the bucket is designed to dump its
contents. It has no guardrails and no way to prevent the bucket
from dropping if hydraulic power fails.
Recognize secondary hazards
Many accident victims recognize hazardous situations, but
they misjudge the seriousness of the hazard because of secondary
factors. For example, icy, muddy or manure-covered surfaces
make the work area slick and increase the risk of injury.
Bystanders or children in the work area can distract the operator,
or limit operator vision.
In many situations you can't eliminate the hazard while working
but you can reduce the hazard. Remove or eliminate secondary
factors that are under your control. Keep the work area clean
and uncluttered. Control access to the work area and shut down
operations when others enter it.
Consider human factors
Skid steer operators can misjudge their ability to stop or avoid
a dangerous situation. This is common when operators work around
powerful equipment every day and become comfortable with their
ability to control the machinery. However, operators are limited
by their reaction time. Time varies by individual, and with
age and physical condition. Human reaction time is not quick
enough to avoid accidents with machinery.
Gravity
Gravity also is faster than human reaction. For
example, it is very dangerous to reach underneath the hydraulic
loader arm of a skid steer loader. If the hydraulic line breaks,
gravity could pull the loader bucket to the ground at a rate
of about 9 feet in three fourths of a second, and crush the extended
arm of the operator.
- Fuel and oil, hydraulic fluid, cooling system fluid,
operator cab, seat belt and seat bar.
- Lift arm and cylinder pivot points, and tires.
- Follow the manufacturer's recommendations about how often
to lubricate all the "lube" points
- Be familiar with the location and function of all the
controls
- Start the engine and check all controls to see that they
are functioning properly.
- Check horn and backup alarm to see that they are working
- Depending upon the job, you should wear some or all of
the following safety equipment: sturdy pants and shirt,
hard hat, safety glasses or goggles, hearing protection,
safety shoes, gloves, and respirator.
- The skid steer loader should be equipped with seatbelt,
rollover protective structure (ROPS), side screens, starter
interlock switches, backup alarm system, and warning lights
for maximum safety.
- Fill the engine with fuel when engine is shut off and
still cool. Do not smoke. Wipe up any spills immediately.
- Check the machine daily for broken, loose, or damaged
parts.
- Check to see that counterweights as recommended by the
manufacturer are in place. NOTE: This is very important
as improperly balanced skid-steer loaders are easily upset.
- Clean steps, pedals, and floor of any slippery substances.
- Clear the driving compartment of loose items that might
interfere with the controls.
- Check the work area for hazards such as holes, soft spots,
and obstructions. Check overhead for utility lines, doorway
clearances, or other obstructions.
- Mount the machine wearing clean, dry shoes using the
grab bars or handrails provided.
- Adjust the seat, fasten the seat belt, set the brake,
and place transmission in park or neutral before cranking
the engine.
- Riders must never be permitted on a skid steer loader
-it is a one-person machine.
- Visually check for the presence of others in the area
and warn them away. Be especially alert for children.
- If the machine is started indoors leave the door or some
windows open for ventilating the exhaust. CARBON MONOXIDE
KILLS!
- Operate with caution on uneven surfaces. Avoid steep
slopes completely.
- If it is essential to drive over a bumpy surface, travel
slowly and raise the bucket just high enough to clear the
ground. Always travel up and down slopes never across.
- Try to go around obstacles, rather than over or through
them. Typical hazards include ditches and curbs. If these
have to be crossed, reduce speed to maintain control, raise
the bucket just high enough to clear the obstacle and cross
at an angle.
- Carry the load as low as possible. Avoid sharp turns
and slopes with a raised load.
- Always keep skid arms down when traveling or turning.
Stability of the machine decreases as the loader arms are
raised. Also you need to keep the arms down to be able to
see the front and sides of the machine.
- Keep the back of the machine pointed uphill. BACK UP
AND DRIVE DOWN!
- Operate with extreme caution near areas with a sharp
drop off. The earth could shear and send your machine crashing
to the bottom. The general rule is to stay as far away from
the edge of the drop off as possible.
- Do not undercut banks or materials that are piled high,
to avoid falling rocks or cave-ins.
- Be alert, when back-filling, for unstable soils that
could collapse under the weight of the machine.
- Keep your feet on the pedals when operating the loader.
- Use only approved attachments and buckets. Do not over
fill buckets.
- Carry bucket or attachments as low as possible
- Most skid steer loaders feature a quick attach system.
Always make sure that locking devices are in place, even
if you are switching attachments for only a few minutes.
Otherwise, the attachment could break free and roll back
down the loader arms, or fall onto a bystander.
- Drive with caution and check behind you before backing
up.
- Load, unload, and turn on level ground.
- With a full bucket go up and down slopes with the heavy
end of the loader pointed uphill. With a full load the front
carries the most weight.
- With an empty bucket go up and down slopes with the heavy
end pointed up With no load the front of the loader is the
heaviest
- Keep Skid steer road travel to a minimum. It is safer
and often more efficient to transport a loader on a trail.
If is necessary to go on the road, be sure to display a
slow moving vehicle sign on the rear of the loader and obey
all traffic rules and regulations.
- Before starting maintenance work , you should lower the
loader arms, engage the parking brake , shut down the engine
, remove the key ,and tag the loader as "out of service"
- If it is necessary to carry out repairs with the loader
arms raised, be sure to lock the arms in place.
- Never leave the machine without first lowering the bucket,
stopping the engine, setting the parking brake, and placing
the shift in park or neutral.
- If stopping for any length of time lock the ignition
and remove the key.
- Never ram the attachment in to a manure pack or pile
of material. The greatest amount of power is transferred
to the wheels with minimal steering lever movement. Drive
slowly into the material, then raise the front of the attachment.
Back away from the load in the tilted-up bucket or fork.
- Drive to the unloading site with the arms down. Stop,
raise the lift arms and drive forward slowly until the bucket
is just over the spreader or pile. Be ready to lower the
load quickly if the skid steer becomes unstable. Use the
hydraulics to keep the bucket level while raising the loader
arms. This will prevent the material from falling over the
back of the bucket. Tilt the bucket fully forward to dump
the load.
- Because hydraulic failure is always a possibility, a
loader must never be used as work platform or personnel
carrier.
- To backfill a trench, lower the lift arms and put the
bucket's cutting edge on the ground. Drive slowly into the
material; push it into the hole. Tilt the bucket forward
as soon as it clears the edge of the trench.
- Never lift, swing, or otherwise move a load over anyone.
Material could fall from the bucket and strike a person.
There is also a risk of hydraulic system failure.
- Take care when handling loose materials, such as rocks.
Lifting the load too high and rolling the bucket back too
far could cause the objects to fall into the cab. That's
why it is so important to keep the attachment level while
the arms are being raised.
- Avoid dumping over a fence or similar obstructions that
could enter the cab if the loader were to tip forward.
- Do not use loader without approved rollover protection
(ROPS) and falling object protection (FOP) cab.
- Do not exceed rated operating capacity.
- Do not carry passengers.
- Do not use the bucket lift people or use as a work
platform.
- Do not make sharp, fast turns or move bucket controls
abruptly.
- Do not travel or turn with lift arms up.
- Do not leave loader with engine running or with
lift arms up.
- Do not travel across a slope. Go straight up or
down slopes with the "heavy" end of the loader pointed
uphill.
- Do not approach overhead wires.
