The attachment is usually shipped in an upright position. Extreme care must be used when
inverting the attachment for installation.
Follow the excavator OEM’s removal and safety instructions to remove the bucket or other stick
attachments.
Position the attachment upside down on flat, solid ground.
Blocking may be required to raise the mounting bracket into
proper position.
Track the excavator to the attachment with the jaws facing the
operator. Lift the excavator stick over the attachment,
carefully positioning the stick tip connection with the
attachment mounting main pivot bore. Pin the excavator stick
to the attachment.
Slowly raise the boom to lift the attachment, allowing the
cylinder pivot connection to come within range of the
excavator cylinder stroke.
Extend the excavator cylinder until the power link bore lines
up with the cylinder pivot connection. Pin the excavator
cylinder to the attachment.
Crowd and extend the attachment, checking closely to make sure there is no interference between
the bracket and hard lines. Also check for interference between the cylinder and boom/stick.
Install excavator hydraulic hoses, supply and return, from the stick tip to the attachment manifold
blocks. See page 23 for electrical installation.
The stick and bucket circuits are oriented as to rod and bore sides of their respective cylinders. Be
sure to connect rod-to-rod and bore-to-bore when connecting a circuit to the attachment. When
these are reversed, extra pressure is needed to open the jaw, which pulls down the engine,
de-strokes the pumps, increases jaw cycle time, creates high oil temperature and burns more fuel.
The attachment must be vertical before putting oil into it or an air lock in the regen valve may
prevent the jaw from opening.

WARNING
Be sure hydraulic pressure is relieved before disconnect-
ing hydraulic fittings. Remove necessary fittings SLOWLY.
