7. Operate hydraulic controls to verify control lever
movements function properly and equipment
movements are correct. Make any necessary
changes to controls and hydraulic hook-ups before
putting equipment into service.
8. Operate grapple through its full range of movements
to check for clearances.
9. Purge hydraulic system of trapped air by operating all
hydraulic functions several times before putting unit
into service. Refer to
“Purging Hydraulic System”
on page 13 in this manual and your skid steer/tractor
Operator’s Manual if any hydraulic function continues
to operate erratic.
Operating Safety
DANGER
!
To prevent serious injury or death:
•
A Crushing hazard always exists around attachments. A
person can become pinched or crushed as the attachment is
rotated, raised, and/or lowered. Objects in the attachment
can shift and fall.
•
Make sure the machine is stopped on solid, level ground
before raising load to dump. To maintain stability, raise
load only to the height necessary to complete the dump.
•
Never dump a load around gas lines, overhead power lines,
utilities, or other hazards that can cause serious injury or
death from electrocution, explosion, or fire.
•
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.
•
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.
•
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.
•
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.
•
Do not lift a load that cannot be contained or have objects
smaller than the openings in the attachment.
•
Keep load positioned forward enough to prevent accidental
spillage on operator and power machine.
•
Keep load slightly tilted back to secure its weight against
the hitch frame. Rotating top of hitch frame back too far can
cause load to shift and fall rearward onto the machine and/
or operator. Rotating top of hitch frame forward too far can
cause load to shift and fall forward.
Section 2: 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 Rock Grapple. 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.
Perform the following inspections before using your
Grapples.
General Inspection
Make the following inspections with grapple attached to a
skid steer/tractor that is parked on a level surface.
1. Complete Operating Checklist table provided above.
2. Inspect skid steer/tractor 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 grapple. Make sure skid
steer/tractor hitch is secured under grapple’s top
angle bar, lock pins extend fully through bottom slots
in grapple hitch, and handles are locked down.
4. Consult your skid steer/tractor Operator’s Manual to
determine if ballast is required. Add ballast if needed.
5. Inspect condition of hydraulic hoses, fittings, and
valves before starting the machine. Make sure hoses
are not pinched, kinked, twisted, or frayed and that
they will not contact 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.
