Original Instructions
5.4 Attaching the hydraulic
attachment to the carrier
5.4.1 Mechanical mounting aspects
You need an assistant to attach the hydraulic attachment
to the carrier.
n
Agree on hand signals with your assistant, to enable
him to help you placing the carrier in the proper posi-
tion to attach the hydraulic attachment.
n
Lower the stick of the carrier into the holder provided
on the adapter plate.
WARNING Injury by impacts
A sudden movement of the carrier may cause your as-
sistant to be hit and injured by the boom or the hydraulic
attachment.
u Only move the boom very slowly and in a controlled
manner while an assistant is within the danger zone.
u Always keep sight of your assistant.
WARNING Hands and fingers being cut off or hurt
Bores and surfaces can act like a pair of scissors and
cut off or hurt parts of your body.
u Never use your fingers to check bores or fitting sur-
faces.
n
Let your assistant instruct you until the bores in the
adapter plate(B) and in the stick(A) are properly
aligned.
n
Install the stick bolt(C) and lock it.
n
Lift the hydraulic attachment(D).
n
Extend the bucket cylinder(E) until the bore in the
linkage(F) links up with the bore in the adapter
plate(B).
n
Install the linkage bolt(G) and lock it.
n
Carefully move the bucket cylinder(E) into both end
positions.
The adapter plate must not be stopped by mechanical
stops in either position. Consult the Epiroc Customer
Center/Dealer in your area if the adapter plate is stopped
by a mechanical stop.
5.4.2 Making the hydraulic connections
NOTICE Faulty hydraulic installation
The carrier must have a suitable hydraulic installation to
operate the hydraulic attachment. Improperly installed
lines and incorrectly rated sizes may cause the oil to
heat up and the hydraulic attachment to be damaged.
u Only use hydraulic lines of the rated sizes as in-
structed (see chapter Technical Specifications).
u Check the rated size of the hydraulic lines on existing
hydraulic installations! All supply and return lines for
the hydraulic oil must have a sufficient inside diame-
ter and wall thickness.
u Route all hydraulic hoses in a torsion-free manner.
n
Switch off the carrier.
n
Depressurise the hydraulic system according to the
manufacturer's safety and operating instructions for
the carrier.
n
If no quick couplings are used, close all shut-off
valves in the installation at the boom.
