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 connected
together when the tool is not connected to the machine.
Assembly
• 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 machine.
• Ensure that the tool is turned the right way round. Viewed
from behind, the pressure connection of the tool should be
connected on the left side (B port) and the return hose on
the right side (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.
• Shut off the machine.
• Insert the wedge so that the holes for the locking pin fit.
• Insert the locking pin.
• Connect the hydraulic hoses and any hoses for hammer
lubrication (when fitting the hammer). Viewed from the
rear, the tool’s return hose must first be connected to the
right side (A port) and then the delivery hose to the left
side (B port).
The hydraulic hoses are equipped with quick couplings
with decompression. This facilitates fitting the hoses even
though pressure is trapped.
• To dismantle, follow the instructions in the reverse order.
Storage
Store the tools safely and inaccessible to unauthorised
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.
!
CAUTION! 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.
!
CAUTION! Ensure that the tool is correctly
and securely fitted. If a tool unexpectedly
comes loose it can cause personal injury.
