Coupling and uncoupling the attachments is described below for a bucket. If you are fitting
or removing attachments with their own hydraulic functions – e.g. grab or offset bucket –

an attachment onto a quickhitch.
Specific safety instructions
Warning!
Personal injury hazard. Using improper tools or installation techniques while
coupling attachments can cause injury.
• Couple attachments only when the engine is stopped.
• Do not attempt to couple / uncouple attachments on sloping or uneven
surfaces. The excavator and the attachment to be coupled / uncoupled
shall be on firm surfaces to avoid sudden unintentional movement.
• Align the attachment holes in the bucket with a drift to facilitate sliding the
pin into the respective holes provided for the connection between attach-
ment and stick.
• Do not attempt to correct misalignment by using the connecting pin and a
hammer. Striking the pin with a hammer can result in a steel chip or splin-
ter being released.
• Always wear protective goggles, helmets, gloves, and other safety equip-
ment when installing the attachment connecting pins.
• Do not remove the connecting pins from the bucket attachment unless the
bucket has been stabilized to prevent motion when the connecting pins
are removed. Do not stand on the closed (back) side of the bucket attach-
ment when disconnecting the bucket.
• Do not attempt to disconnect the bucket attachment until it rests firmly on
the ground or a stable surface. Removing the connecting pins of the
bucket attachment with the attachment raised is an unsafe practice that
will create a hazardous condition from the falling bucket.
• Do not align the connecting holes with fingers. Do not place fingers and
hands over the connecting brackets to align the connecting hole to avoid
potential shearing, pinching or crushing injuries.
• After the attachment is connected to the excavator stick and before
resuming operation, make sure the attachment is safely locked with the
stick and the tilt rod, or with the quick hitch option.
