COLD WEATHER OPERATION
CAUTION:
NOTE:
For cold weather operation, near and below freezing, the moisture in the air line may
freeze and prevent tool operation. We recommend the use of permanent antifreeze
(ethylene glycol) as a cold weather lubricant.
Do not store tools in a cold-weather environment to prevent frost or ice
formation on the tools operating valves and mechanisms, which could cause
tool failure. Test tool without fasteners prior to operations to ensure no
malfunction on the tool due to ice formation.
Some commercial air line drying liquids are harmful to O-Rings and seals – do
not use these low temperature air dryers without checking compatibility.
NAIL LOADING
EYE PROTECTION which conforms to ANSI/ CE specifications and provides
protection against flying particles both from the FRONT and SIDE should
ALWAYS be worn by the operator and others in the work area when
connecting to air supply, loading,
operating or servicing this tool. Eye
protection is required to guard against flying fasteners and debris, which
could cause severe eye injury.
The employer and/or user must ensure that proper eye protection is worn.
Eye protection equipment must conform to the requirements of the ANSI
Z87.1 and 89/686/EEC, and provide both frontal and side protection. NOTE:
Non-side shielded spectacles and face shields alone do not provide adequate
protection.
TO PREVENT ACCIDENTAL INJURIES:
Never place a hand or any other part of the body in nail discharge area of
tool while the air supply is connected.
Never point the tool at anyone else.
Never engage in horseplay.
Never pull the trigger unless nose is directed at the work.
Always handle the tool with care.
Do not pull the trigger or depress the trip mechanism while loading the
tool.
LUBRICATION
Frequent, but not excessive, lubrication is required for best performance. A i r - t o o l
o il added through the air line connection will lubricate the internal parts. Do not use
detergent oil or additives as these lubricants will cause accelerated wear to the seals
and bumpers in the tool, resulting in poor tool performance and frequent tool
maintenance.
If no air line lubricator is used, add oil during use into the air fitting on the tool once or
twice a day. Only a few drops of oil at a time is necessary. Too much oil will only
collect inside the tool and will be noticeable in the exhaust cycle.

rapid fastener placement on many jobs, such as sheathing, decking and pallet assembly. All pneumatic tools are
subject to recoil when driving fasteners. The tool may bounce, releasing the trip, and if unintentionally allowed to
recontact the work surface with the trigger still actuated (finger still holding trigger pulled) an unwanted second fastener
will be driven.
SEQUENTIAL TRIP: IDENTIFIED BY NICKEL PLATED TRIGGER
Available on the FCN90B, FCN90L, FCN90LB, SCN90L & PN90
The Sequential Trip requires the operator to hold the tool against the work before pulling the trigger. This makes accurate
fastener placement easier, for instance on framing, toe nailing and crating applications. The Sequential Trip allows
exact fastener location without the possibility of driving a second fastener on recoil, as described under “Contact Trip”.
The Sequential Trip Tool has a positive safety advantage because it will not accidentally drive a fastener if the tool is
contacted against the work – or anything else – while the operator is holding the trigger pulled.
If trigger system is not operating as described, do not use the tool and
contact your nearest service center.
REMOTE FIRE: IDENTIFIED BY CONTROL VALVE AIR INLET

AIR SUPPLY AND CONNECTIONS
DO NOT USE OXYGEN, COMBUSTIBLE GASES, OR BOTTLED GASES AS A
POWER SOURCE FOR THIS TOOL AS TOOL MAY EXPLODE, POSSIBLY
CAUSING INJURY.
FITTINGS: Install a male plug on the tool which is free flowing and which will release
air pressure from the tool when disconnected from the supply source.
HOSES: Air hoses should have a minimum of 150 PSI (10.6 kg/cm
2
) working
pressure rating or 150 percent of the maximum pressure that could be produced in
the air system. The supply hose should contain a fitting that will provide “quick
disconnecting” from the male plug on the tool.
SUPPLY SOURCE: Use only clean, regulated compressed air as a power source for this
tool. NEVER USE OXYGEN, COMBUSTIBLE GASES, OR BOTTLED GASES AS A
POWER SOURCE FOR THIS TOOL AS TOOL MAY EXPLODE.
REGULATOR: A pressure regulator with an operating pressure of 0 - 125 PSI (0 -
8.79 kg/cm
2
) is required to control the operating pressure for safe operation of this
tool. Do not connect this tool to air pressure which can potentially exceed 200 PSI (14
kg/cm
2
) as tool may fracture or burst, possibly causing injury.
OPERATING PRESSURE: Do not exceed recommended maximum operating
pressure as tool wear will be greatly increased. The air supply must be capable of
maintaining the operating pressure at the tool. Pressure drops in the air supply can
reduce the tool’s driving power. Refer to “TOOL SPECIFICATIONS” for setting the
correct operating pressure for the tool.
FILTER: Dirt and water in the air supply are major causes of wear in pneumatic tools.
A filter will help to get the best performance and minimum wear from the tool. The
filter must have adequate flow capacity for the specific installation. The filter has to be
kept clean to be effective in providing clean compressed air to the tool. Consult the
manufacturer’s instructions on proper maintenance of your filter. A dirty and/or
clogged filter will cause a pressure drop which will reduce the tool’s performance.
