Changing tools
IMPORTANT!
Changing tools may mean that the operator has
to be within the machine’s risk area. Ensure that
nobody unintentionally starts the machine while
the tool is being changed. Keep a sharp watch
on the machine and be prepared to turn it off.
Guard hands and feet against crushing.
Cleaning
Prevent dirt from entering the hydraulic system by:
• Wiping dirt off the couplings before assembling or
dismantling.
• Placing dust guards on the machine’s hydraulic
couplings when no tool is mounted.
• Ensuring that the tool’s hoses are always con-
nected together when the tool is not connected to
the machine.
Fitting
IMPORTANT!
Ensure that the tool is correctly and securely
fi tted. If a tool unexpectedly comes loose it can
cause personal injury.
• Ensure that the machine is situated on a stable
surface with the outriggers down.
• Position the tool with the holder facing the machine
at a suitable distance, not too close to the ma-
chine.
• Ensure that the tool is turned the right way round.
The tool’s pressure connection must be connected
to the main valve’s B-port and the return hose to
the main valve’s A-port.
• Direct the tool holder so that it grips the tool.
Tighten the tool by raising the arm system and
manoeuvring cylinder 4 in.
TOOLS
• Shut off the machine.
• Insert the wedge so that the holes for the locking
pin fi t.
• Insert the locking pin.
• Connect the hydraulic hoses and any hoses for
hammer lubrication (when fi tting the hammer). The
tool’s pressure connection must be connected to
the main valve’s B-port and the return hose to the
main valve’s A-port.
The hydraulic hoses are equipped with bayonet
couplings with decompression. This facilitates fi t-
ting the hoses even though pressure is trapped.
To dismantle, follow the instructions in the reverse
order.
Storage
Store the tools safely and inaccessible to unauthor-
ised people. Ensure that they are in a stable position
and cannot tip over. If tools are placed high up or on
a slope they must be secured so that they cannot
be put into motion or fall. Protect the tools’ hydraulic
couplings against dirt and damage.
