CORRECT AIR PLANT AND
CORRECT INSTALLATION OF THE TOOL
It is very important for the proper functioning of the tool that the air plant be correctly positioned and produces
clean, dry, filtered compressed air in the right quantity and at the right pressure.
Never attempt to use oxygen, combustible gases or any bottled gas under pressure as an energy source for the
tool. It will explode, causing serious injury and/or death.
Never exceed the maximum recommended working pressure of 8.9 bar (130 psi).
Never connect the tool to an air line whose pressure may potentially exceed 9.3 bar (135 psi) should the in-line
pressure regulator fail.
BEFORE STARTING TO USE THIS TOOL OR BEFORE CARRYING
OUT MAINTENANCE, PLEASE READ CAREFULLY ALL THE

YOUR TOOL - SAFETY ASPECTS
When the tool is in use, the user and all others in the area must wear eye protection which conforms to the
laws in force in your country. It is the responsibility of the employer to ensure that approved eye protection is
available and is being used by the operator and all others in the work area.
Other forms of personal protection equipment such as hard hats, steel toecaps and mail gloves, etc. Must be
used where required.
This 4.00mm Post Stapler fires genuine Delfast 4.00mm post staples in Plain, Barbed or Ribbed.
The work contacting elements used in the Delfast 4.00mm post stapler is sequential action. Read carefully
the parts diagram which accompanies this manual or try the tool without fasteners in order to understand the
system used on this model.
Sequential action—Once the nose of the tool has been pushed against the work piece, it can be actuated once
until the nose is lifted away from the workpiece. At this point the tool will stop working and will not work again
until the nose is again pushed firmly against the workpiece.
The tools and fasteners must always be considered as one system from the point of view of safety. Mistreating
the tool can result in a fastener being fired causing injury or death.
Any attempt to modify the tool in any way, without the written approval from Delfast, will void the warranty.
Do not remove or render inoperable any of the operating controls. Never tamper with, block or remove the work
contacting element.
Remove the tool from the air supply if left unattended, when moving to a new workplace or when climbing or
descending ladders.
Always remove the finger from the trigger when not driving fasteners.
Inspect the tool thoroughly before connecting it to the airline. Do not attempt to use a tool which appears
to have been damaged, modified or to have pieces missing. When using the tool for the first time, or when
returning to the tool after a period of time, always check that the magazine is empty before connecting the
tool to the air supply and try it a few times without fasteners before loading. Try the tool a few more times on a
waste workpiece before starting work.
