IMPORTANT SAFETY INSTRUCTIONS
There are certain applications for which this tool was designed. We strongly recommend that
this tool SHALL NOT be modified and /or used for any application other than for which it was
designed.
WARNING: When using pneumatic tools, basic safety precautions should always be followed
to reduce the risk of personal injury, including the following:
web: support.primatech.ca
• KEEP WORKING AREA CLEAN. Cluttered areas
invite injuries.
• DON’T ALLOW CHILDREN IN THE WORKING
AREA. Don’t let them handle the tool.
• USE SAFETY GLASSES. To prevent eye injuries,
the tool operator and all persons in the working are
a must wear safety glasses with permanently
attached, rigid, plastic side shields. These safety
glasses must conform to ANSI Z87.1 requirements
(approved glasses have " Z87" printed or stamped
on them).
• USE EAR PROTECTION. The working area may
be exposed to high noise levels that can lead to
hearing damage.
• USE ONLY CLEAN, dry and regulated compressed
air at 70 to 120 PSI (4.8 to 8.3 BAR).
• DO NOT CONNECT TOOL to pressure that
potentially exceeds 180 PSI (12.3 BAR).
• ONLY USE AIR HOSE THAT IS RATED for 150%
of the maximum system pressure. Please try to use
a hose of ID 3/8 connecting nailer with compressor.
• NEVER USE OXYGEN, CARBON DIOXIDE,
combustible gases or any other bottled gas as a
power source for this tool: explosion and serious
personal injury could result.
• 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.
• BEFORE USING TOOL, carefully check if there is
any part damaged to obtain ideal results. Do not
use the tool if the tool has any air leaks,
uncompleted, damaged parts or needs repairing.
• NEVER USE TOOL if safety trigger or spring is
inoperable, missing or damaged. Do not alter or
remove safety, trigger or springs. Make daily
inspections for free movement of trigger and safety
mechanism.
• DO NOT USE TOOL WITHOUT SAFETY
WARNING LABEL. If label is missing, damaged or
unreadable, contact your local agencies.
• ONLY USE PARTS AND FASTENERS
recommended by Primatech.
• CONNECT TOOL TO AIR SUPPLY BEFORE
LOADING FASTENERS, to prevent a fastener from
being fired during connection. The tool driving
mechanism may cycle when tool is connected to the
air supply. When not in use, remove all the
fasteners from the magazine.
• ALWAYS ASSUME THE TOOL CONTAINS
FASTENERS. Keep the tool pointed away from
yourself and others at all times. No horseplay,
respect the tool as a working implement.
• DO NOT LOAD FASTENERS with trigger or safety
depressed, to prevent unintentional firing of a
fastener.
• REMOVE FINGER FROM TRIGGER when not
driving fasteners. Never carry tool with finger on
trigger: tool will fire a fastener if safety is bumped
while trigger is depressed.
• DON’T OVER REACH. Keep proper footing and
balance at all times when using or handling the tool.
• FIRE FASTENERS INTO WORK SURFACE ONLY:
never into materials too hard to penetrate.
• GRIP TOOL FIRMLY TO MAINTAIN CONTROL
while allowing tool to recoil away from work surface
as fastener is driven. If safety bracket is allowed to
contact work surface again before trigger is
released, an unwanted fastener will be fires.
• 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.
• DO NOT DRIVE FASTENERTS TOO CLOSE to
edge of the work piece. The work piece is likely to
split allowing the fastener to fly free or ricochet,
causing personal injury.
• KEEP TOOL POINTED AWAY from yourself and
others at all times.
• KEEP HANDS AND BODY PARTS away from area
shown in Fig. 13A to avoid injury.
OPERATING INSTRUCTIONS
Model 534FN is pneumatic framing nailer designed to install 15GA diameter framing nails in
lengths of 1-1/4" (32mm) to 2-1/2" (63mm). Fastener collation angle is 34°.
AIR SUPPLY
This tool is designed to operate on clean, dry, compressed air at regulated pessures
between 70 and 120 psi (4.9-8.3 bar). The preferred system would include a filter, a
pressure regulator, and automatic oiler located as close to the tool as possible, ideally
within 15 feet. 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 about six drops of oil into the tool’s air inlet at the beginning of each workday.
CAUTION: All line components (hoses, connectors, filters, regulators, etc.) must meet 150%
of the maximum system pressure. The use of a hose of ID 3/8" is recommended.
Do not connect this tool to a system with maximum potential pressure greater than 180 psi
(12.3 bar).
LOADING THE TOOL
CAUTION:
Always connect tool to air supply before loading fasteners.
Do not load fasteners with trigger or safety depressed.
Never use a tool that leaks air or needs repair.
• Insert a strip of nails into rear of magazine then push nails forward and beyond the pusher
(Fig. 15).
• Pull the pusher to the rear of the magazine until it engages behind the fasteners (Fig. 17).
• Grasp and rotate directional exhaust deflector (Fig. 18), so that the exhaust air blast will
be directed away from the operator.
OPERATING THE TOOL
This nailer is equipped with a safety contact and will not operate unless the safety contact is
depressed against the work piece.
The 534FN can be operated in two different ways: trigger fire (single sequential) or bump fire
(contact actuation).
CAUTION: Read and understand operating manual before changing the trigger mode.
Improper use may result in serious injury.
Trigger firing (single sequential):
Rotate the selector upwards as shown on Fig. 18A.
Position the nose on the working surface and lightly
push the tool downward until the safety contact is
depressed, then, pull the trigger to drive the fastener.
Allow tool to recoil off the surface to avoid a second
unwanted fastener to be fired. In this method, the safe
bracket can be adjust downwards with knob to avoid
striking two nails at one time. This "trigger fire" method
provides the most accurate fastener placement.
Original factory setting is single sequential trigger mode.
Dual-action firing (also referred to as bump fire or contact
actuation):
Rotate the selector downward as shown on Fig. 19A.
Pull and hold the trigger, then repeatedly impact (bump)
the safety contact against the work piece. The tool can
repeatedly drive the fasteners. The tool will drive one
fastener every time the safety contact is bumped againt
the work piece. This method will increase work
efficiency.
CAUTION: Remove finger from trigger when not driving fasteners.
Never carry tool with finger on trigger: tool will fire a fastener if safety is bumped.
Keep tool pointed in a safe direction at all times.
Never attempt to drive a fastener into material that is too hard, or at too steep an angle, or
near the edge of the workpiece. The fastener can ricochet causing personal injury.
Disconnect tool from air supply before performing maintenance, clearing a jammed
fastener, leaving work area, moving tool to another location, or handing the tool to another
person, and making adjustments.
The depth to which a fastener is driven is adjusted by the adjusting knob on the safety
contact (see ¥A¦ on Fig. 19). The depth of drive is adjusted to a maximum setting by the
factory. Rotate adjusting nut ¥A¦ to desired position, fire another fastener and check depth.
Repeat as necessary to achieve desired results. The amount of air pressure required will vary
depending on the size of the setting to determine the lowest setting that will consistently
perform the job at hand. Air pressure in excess of that required can cause premature wear
and/or damage to the tool.
A rubber nose cushion (see ¥B¦ on Fig. 19) is provided to reduce marring of the work surface.
The rubber cushion can be pulled off to provide increased depth-of-drive.
CAUTION: Disconnect tool from air supply before removing or reinstalling rubber cushion.
CLEARING A JAMMED FASTENER
CAUTION: Always disconnect tool from air supply before clearing a jam.
• Remove all remaining fasteners from the magazine.
• Open the latch on the front end of the nose and use a pair of needle nose pliers or a flat
screwdriver to remove bent fastener from guide body (Fig. 22, 23).
MAINTENANCE
CLEAN AND INSPECT DAILY
Clean and inspect tool daily. Carefully check for proper operation of trigger and safety
mechanism. Do not use the tool unless both the trigger and the safety mechanism are
functional, or if the tool is leaking air or needs any other repair.
CAUTION: Disconnect tool from air supply before cleaning and inspection. Correct all
problems before operating.
Wipe the tool clean and inspect for wear or damage. Use non-flammable cleaning solutions
to wipe exterior of tool only if necessary. Do not soak tool with cleaning solutions. Such
solutions can damage internal parts
Keep all screws tight. Loose screws can cause personal injury or damage tool.
If tool is used without an in-line oiler: put 5 or 6 drops of pneumatic tool oil into the air inlet
of the tool at the beginning of each workday.
