TOOLS
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 Þtted. 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
•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 Þt.
•Insert the locking pin.
•Connect the hydraulic hoses and any hoses for hammer lubrication (when Þtting the hammer). The tool’s pressure connection must be connected to the main valve’s
The hydraulic hoses are equipped with bayonet couplings with decompression. This facilitates Þt- 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.
