Operating Safety
DANGER
!
To avoid serious injury or death:
• All guards and shields must be installed and in good
working condition while operating the implement.
• Do not attach Stump Grinder to a tractor loader. The driver
can not see the unit in front of the tractor to position it or to
watch it while it is working. Not having good visibility of
your work area can cause a serious injury or death.
• Always operate skid steer while seated in the cab with seat
bar lowered when equipped and seat belt properly fastened.
The operator can be pinched, crushed, or thrown if not
properly seated in the cab or if operating loader arms from
outside the cab.
• Keep attachment, loader arms, and/or load away from
overhead electrical power lines. Place an orange warning
sign under overhead lines indicating type of danger above.
• Keep attachment, loader arms, and/or load away from
overhead electrical power lines. Place an orange warning
sign under overhead lines indicating type of danger above.
• A crushing hazard that can cause serious injury or death
always exists around power equipment.
• The operator of this attachment must know how to control
the power machine with attachment and how to stop them
quickly in an emergency.
• Do not drive up to anyone or an animal in front of a fixed
object such as a wall or bench. Never assume that the power
machine will stop in time.
• Keep bystanders, pets, and livestock away from your work
area. Never allow anyone to go near or under the
attachment or its load. The attachment and/or load can fall.
• Always secure equipment with solid, non-concrete supports
before working under it. Never go under equipment
supported by concrete blocks or hydraulics. Concrete can
break, hydraulic lines can burst, and/or hydraulic controls
can be actuated even when power to hydraulics is off.
WARNING
!
To avoid serious injury or death:
• Never make contact with underground utilities such as
electrical power lines, gas lines, phone lines, etc. They can
cause serious injury or death from electrocution, explosion,
or fire. If in doubt, call 811 (USA) before digging so that
they can mark the location of underground services in the
area. For contact information, see Dig Safe in the
“Important Safety Information” starting on page 1.
Section 3: Operating Procedures
Operating Checklist
Hazard control and accident prevention are dependent
upon the awareness, concern, prudence and proper
training involved in the operation, transport, storage, and
maintenance of the Stump Grinder. Therefore, it is
absolutely essential that no one operates the unit unless
they are age 16 or older and have read, fully understood,
and are totally familiar with the Operator’s Manual. Make
sure the operator has completed the Operating Checklist
below.
General Inspection
Make the following inspections with Stump Grinder
attached to a skid steer that is parked on a level surface.
1. Complete Operating Checklist table provided above.
2. Inspect skid steer safety equipment to make sure it is
in good working condition and that all safety alert
decals are visible and readable. Replace all missing
and unreadable safety alert decals.
3. Inspect hitch hook-up to grinder. Make sure skid
steer hitch is secured under the grinder’s top angle
bar, lock pins extend fully through bottom slots in
grinder hitch, and handles are locked down.
4. Inspect wiring harness and connection points before
starting the skid steer. Make sure harness and
connectors are not pinched, frayed, or broken and
that they will not come in contact with moving parts.
5. Inspect hydraulic hoses, fittings, and valves before
starting the skid steer. Make sure hoses are not
pinched, kinked, twisted, or frayed and that they will
not come in contact with moving parts.
6. Hose sleeves help protect hoses from wear and
operator from oil sprays. Inspect hose sleeves to
make sure they are properly secured to the hydraulic
hoses, are not torn, and are not worn thin. Replace
hose sleeve if worn thin, torn, or not properly secured
to hydraulic hoses.
