OPERATING INSTRUCTIONS
4.1 Preparing a tool for first time operation
Please Read and observe these Operating Instruction before using the tool. Basic safety measures should always be strictly followed
to protect against damage to the equipment and personal injury to the user or other people working in the vicinity of operation.
4.2 Connection to the compressed air system
Ensure that the pressure supplied by the compressed air system does not exceed the maximum allowable pressure of
the fastener driving tool. Set the air pressure initially to the lower value of the recommended allowable pressure (see
TECHNICAL DATA). Empty the magazine to prevent a fastener from being ejected at the next stage of work in the event
that internal parts of the fastener driving tool are not in the starting position following maintenance and repair work or
transportation. Connect the fastener driving tool to the compressed air supply using suitable pressure hose equipped
with quick-action connectors. Check for proper functioning by applying the muzzle of the fastener driving tool to a piece
of wood or wooden material and actuating the trigger once or twice.
