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 14 in this manual and your skid steer/tractor 

Operator’s Manual if any hydraulic function continues 

to operate erratic.

Operating Safety

DANGER

!

To avoid serious injury or death:  

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 in the 

attachment, exceeds the attachment’s load guard height, or 

has objects smaller than the openings in the load guard.

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.

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 all objects are contained and/or secured before 

lifting. Do not lift a load that cannot be contained in the 

attachment as the load can shift and fall.

Use a “spotter” when it is hard to see in the direction you 

are traveling and when placing a load that obstructs your 

vision. A person or animal could be nearby in a blind spot.

Keep load slightly tilted back to secure its weight against 

the vertical face of the attachment. Rotating front of 

attachment too high can cause the load to shift and fall onto 

the operator or others. Rotating front of attachment level or 

lower can cause the load to fall forward.

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 come in contact with power lines, utilities, gas lines, 

or other hazards, above or below ground. They can cause 

serious injury or death from electrocution, explosion, or 

fire. Before digging, call dig safe 811 (USA only) so utility 

companies can mark the location of underground services in 

the area.

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 the hydraulics is off.

Keep load positioned forward enough to prevent accidental 

spillage onto the operator and power machine.

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 Skeleton Grapple. Therefore, it is 

absolutely essential that no one operates the unit unless 

they have read, fully understood, and are totally familiar 

with the Operator’s Manual. Perform the following 

inspections before using your Skeleton Grapple.

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.

7.

Operate hydraulic controls to verify control lever 

movements function properly and attachment 

movements are correct. Make any necessary 

changes to controls and hydraulic hook-ups before 

putting attachment into service.
