Genesis GHG Handling Grapple 27
Preparation of the excavator prior to attachment delivery will make installation safer and
easier. Contact Genesis or your Genesis dealer for assistance.
Installation Procedure
Note: The attachment is usually shipped in an upright position. Extreme care must be used when
positioning the attachment for installation. Typically the grapple is shipped without hydraulic oil in
the system. If the grapple is raised but the system is charged, the tines will move/close unexpect-
edly. Stand clear when raising the grapple for the first time.
Remove bucket or other stick attachments, following the excavator OEM’s removal and safety
instructions.
GRAPPLE INSTALLATION
!
WARNING
Removing any connecting pin may be hazardous. To
remove a connecting pin, position the attachment on the
ground and properly support.
1. Remove both pins from the grapple.
2. With the excavator stick in a vertical orientation, position the excavator over the stick mounting
pin. Retract the bucket cylinder to move the H-link out of the way. Carefully lower the stick tip
into the GHG lugs and align pin holes. Install the stick pin and cover strap.
3. Slowly extend the bucket cylinder and lower the H-link into the GHG lugs. Align the pin holes
and install the link pin and cover strap.
4. Crowd and extend the attachment, checking closely to make sure there is no interference be-
tween the attachment bracket and hard lines. Also check for interference between the cylinder
and boom/stick.
5. Install excavator hydraulic hoses, supply and return, from the stick tip to the attachment mani-
fold blocks.
6. The stick and bucket circuits are oriented as to rod and bore sides of their respective cylinders.
When you connect a circuit to the attachment, take care to connect rod-to-rod and bore-to-
bore. When these are reversed, extra pressure is needed to open the jaw, which pulls down
the engine, destrokes the pumps, increases jaw cycle time, creates high oil temperatures and
burns more fuel.

WARNING
Particles may fly when a pin is struck. Use a drift pin or
mallet when striking pins. Keep all personnel at a safe
distance.
