9. Do not connect tool to pressure which
potentially exceeds 200 PSI (13.7 BAR).
10. All air line components (hoses,
connectors, filters, regulators, etc.) must
be rated for a maximum working pressure
of at least 150 PSI (10.3 BAR) or 150% of
the maximum system pressure, which ever
is greater.
11. Connect tool to air supply hose with a
coupling that automatically removes all
pressure from the tool when the coupling is
disconnected. Fig. 7.
12. Disconnect tool from air supply hose
before doing tool maintenance, clearing a
jammed fastener, leaving work area, moving
tool to another location, or handing the tool
to another person. Fig. 7.
13. Never use a tool that is leaking air, has
missing or damaged parts, or requires
repair. Make sure all screws and caps are
securely tightened. Fig. 8.
14. Never use tool if safety, trigger or

21. Remove finger from trigger when not
driving fasteners. Never carry tool with finger
on trigger. In “Contact Actuation Mode” tool
will fire a fastener if safety is bumped while
trigger is depressed. Fig. 14.
22. Do not overreach. Keep proper footing
and balance at all times when using or
handling the tool.
23. Fire fasteners into work surface only:
never into materials too hard to penetrate.
Fig. 15.
24. Grip tool firmly to maintain control
while allowing tool to recoil away from
work surface as fastener is driven. In
“Contact Actuation Mode” if safety element
is allowed to recontact work surface before
trigger is released an unwanted fastener will
be fired.
25. Do not drive fasteners on top of other
fasteners, or with the tool at too steep an
angle: the fasteners can ricochet causing
personal injury. Fig. 15.
26. Do not drive fasteners close to the
edge of the workpiece. The workpiece is
likely to split allowing the fastener to fly free
or ricochet causing personal injury. Fig. 16.
27. FOR TOOLS SET FOR CONTACT
ACTUATION MODE, Do not use on
scaffoldings or ladders or for tasks in
which changing location involves the use of
scaffoldings, stairs, ladders, and the like. Do
not use for specific tasks such as closing
boxes or crates or fitting transportation
safety systems on vehicles and wagons.

Porter-Cable Model RN175A is a heavy duty, coil fed, pneumatic roofing
nailer. It is designed to install .120" diameter, 15° wire collated roofing nails
of various lengths from 7/8" to 13/4" long.
Use approved Porter-Cable fasteners only.
POWER SOURCE
This tool is designed to operate on clean, dry, compressed air at regulated
pressures between 70 and 120 PSI (Pounds per Square Inch)
(4.8 to 8.3 BAR) .
The preferred system would include a filter, a pressure regulator, and an
automatic oiler located as close to the tool as possible, within 15 ft/4.6 m is
ideal.
All compressed air contains moisture and other contaminates that are
detrimental to internal components of the tool. An air line filter will remove
most of these contaminates and significantly prolong the life of the tool. If an
in-line oiler is not available: place five or six drops of Porter-Cable Air Tool Oil
into the tool’s air inlet at the beginning of each workday.
The tool is equipped with a 1 / 4" male “quick connector”. A 3 / 8" male “quick
connector” is available from Porter-Cable and may be used in situations where
a 1
/ 4" supply line is not available. A 3 / 8" supply line (and fittings) are required for
maximum tool performance. The tool must always be connected to the air
supply with a coupling such that all pressure is removed from the tool when the
coupling is disconnected.

1. To use the tool in the SINGLE SEQUENTIAL ACTUATION MODE
depress trigger lever pivot pin (A) Fig. 27, rotate arrow to position (B), and
release. Note: Trigger lever pivot pin is spring loaded and held in position by
locking tab (D) Fig. 27 to prevent movement during operation. To fire, grip
tool firmly to maintain control, position nose of tool onto work surface, push
tool firmly against work surface to depress safety, and then squeeze
trigger to fire a fastener, as shown at (S) Fig. 27A. Allow tool to recoil
away from work surface as fastener is driven. This “single sequential
actuation” method provides the most accurate fastener placement.

2. To use the tool in the CONTACT ACTUATION MODE depress trigger
lever pivot pin (A) Fig. 27, rotate arrow to position (C), and release. Note:
Trigger lever pivot pin is spring loaded and held in position by locking tab (D)
Fig. 27 to prevent movement during operation. To fire, grip tool firmly to
maintain control, squeeze and hold trigger, push tool firmly against work
surface to depress contact safety and fire a fastener, as shown at (S)
Fig. 27A.Allow tool to recoil away from work surface as fastener is
driven. If safety element is allowed to recontact work surface before trigger
is released an unwanted fastener will be fired. The tool will fire a fastener
each time the contact safety is depressed. This method is known as “contact
actuation” and allows very fast repetitive fastener placement.
IMPORTANT: A trigger, which will limit the tool to “single sequential
actuation” only, is available free-of-charge by calling 1-800-321-9443 in the
United States and Canada or 001-731-660-9374 outside the United States
and Canada, and providing tool model number, type, serial number, etc. For
identification purposes: the single sequential actuation trigger is red.
