2. COMPRESSED AIR SYSTEM
Proper use of the tool requires an adequate quantity of clean dry
compressed air.
All compressed air contains moisture and other contaminants that
may be detrimental to the tool, so it is recommended to use an
airsupplylterregulatorlubricatorasclosetothetoolaspossible
(within4.5meters/15feet).Theltershouldbewellmaintainedsoas
to ensure optimum performance and power. All parts of the air supply
system should be clean and contaminant free.
The tool shall only be connected to a compressed air supply where
the maximum allowable pressure of the tool cannot be exceeded by
a factor of more than 10%. This can be achieved, for example, by a
pressure reduction valve which includes a downstream safety valve.
Amalefree-owcouplingshouldbeconnectedtothetoolsideof
the system with the female coupling providing a seal to prevent air
loss from the compressor tank upon disconnection. Never connect
a female disconnect coupling to the tool side as this may trap air in
the tool when the air supply is disconnected, leaving the tool charged

3.2 GENERAL OPERATING INSTRUCTIONS
3.2.1 TYPES OF ACTUATING AND TRIGGERING SYSTEMS
FOR TOOLS WITHOUT A CONTACT SAFETY:
Single action actuation: The tool contains an actuating
system where the triggering device has to be actuated for
each driving operation.
Single action with simple safety: The tool contains a safety
latch that is built into the triggering device enabling the user
to disengage it when it is not in use.
FOR TOOLS WITH A CONTACT SAFETY INSTALLED:
Dual action safety/contact safety
(contact actuation): It will be necessary to activate
the contact safety mechanism as well as the triggering
deviceinordertoreafastener.Bykeepingthe
trigger activated and activating the contact safety a
fastenerisred,allowingforhighspeedring,also
knownasbumpring.
Single sequential trip re (single-sequential
actuation):Fastenerscanonlyberedbyrst
activating the contact safety by holding the tool
against the workpiece and then by pulling the trigger.
Thereafter any further driving operations can only be
actuated after the trigger has been returned to the
starting position. The single sequential trip tool allows
exact fastener location without the possibility of
driving a second fastener due to recoil.
Changing the trigger: To change the trigger lever, simply
remove the trigger pin, remove the trigger lever and insert the
required one, replacing the trigger pin to hold it in place.

a contact safety it will be necessary to press the tool against
the workpiece so as to activate the contact safety, before
pullingthetriggertoreafastener.
Exhaust air: Each time a fastener is driven a blast of air is
exhausted from the top front area of the tool. Keep your face
clear of the exhaust area. Some tools incorporate a 360°
exhaustdeector,whichenablesyoutocontrolthedirection
of the exhaust air.
Depth control: Check whether the fastener has been
driven into the workpiece in accordance with the
requirements. The driven depth can be changed by
