3. Tool Set-Up and Operation
3.1 SET-UP
Connect the air line to the regulator (see diagram to the
right). Wrap all male threaded connections with “Teflon”
tape prior to assembly to prevent leakage.
NOTE: Make sure that couplers are attached only to the
compressor side of the air supply system, and all com-
ponents are rated for the tool operating pressure.
3.2 Lu b ricate the tool
Use Hilti ATL (Air Tool Lubricant) or an equivalent light-
weight acid-free, non-detergent oil (viscosity 3–4
Engler/20°C; aniline point 60°C).
During normal use, squirt 2–3 drops of oil daily into the
air connector fitting on the tool.
4. Loading the magazine
(Always connect air supply to the tool before loading
fasteners into magazine)
1. Pull the pusher fully back wards until it is held in place
by the pusher latch pin. (1-a)
2. Insert the strips of nails into the magazine and slide
all the way forward. The nail strips should be insert-
ed parallel to the magazine. (1-b)
3. Holding the pusher firmly, release it from the maga-
zine catch and guide the pusher forward until it rests
against the fasteners. Do not allow the pusher to strike
the nail strip with full spring force as it can break up
the collation that holds the nails together and cause
jamming. (There is a built-in firing detent on the push-
er that will prevent the tool from operating when the
magazine is empty.) (1-c)
5. Normal operation
5.1 Adjust the air pressure
To the minimum required to drive the fastener, making
sure never to exceed the maximum rated pressure for
the tool (175 PSI).
5.2 Single fire operation
For precision fastenings, place the tool nose in the cor-
rect position and depress the safety yoke, then quickly
pull and release the trigger. Repeat in a new location.
