SAFETY INSTRUCTIONS
AIR SUPPLY AND CONNECTIONS
LOADING TOOL
OPERATION
MAINTAINING THE TOOL
EYE PROTECTION which conforms to ANSI 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 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 American National Standards
Institute, ANSI Z87.1-1979 and provide both frontal and side protection. NOTE: Non-side
shielded spectacles and face shields alone do not provide adequate protection.
ADDITIONAL SAFETY PROTECTION will be required in some environments. For example, the
working area may include exposure to noise level which can lead to hearing damage. The
employer and user must ensure that any necessary hearing protection is provided and used by
the operator and others in the work area. Some environments will require the use of head
protection equipment. When required, the employer and user must ensure that head protection
conforming to ANSI Z89.1 1986 is used.
Do not use oxygen, combustible gases, or bottled gases as a power source for this tool
as tool may explode, possibly causing injury.
Do not use supply sources which can potentially exceed 200 P.S.I.G. as tool may burst,
possibly causing injury.
The connector on the tool must not hold pressure when air supply is disconnected. If a
wrong fitting is used, the tool can remain charged with air after disconnecting and thus
will be able to drive a fastener even after the air line is disconnected possibly causing
injury.
Do not pull trigger or depress contact arm while connected to the air supply as the tool
may cycle, possibly causing injury.
Always disconnect air supply: 1.) Before making adjustments; 2.) When servicing the tool;
3.) When clearing a jam; 4.) When tool is not in use; 5.) When moving to a different work
area, as accidental actuation may occur, possibly causing injury.
When loading tool: 1.) Never place a hand or any part of body in fastener discharge area
of tool; 2.) Never point tool at anyone; 3.) Do not pull the trigger or depress the trip as
accidental actuation may occur, possibly causing injury.
Always handle the tool with care: 1.) Never engage in horseplay; 2.) Never pull the
trigger unless nose is directed toward the work; 3.) Keep others a safe distance from the
tool while tool is in operation as accidental actuation may occur, possibly causing injury.
The operator must not hold the trigger pulled on contact arm tools except during
fastening operation as serious injury could result if the trip accidentally contacted
someone or something, causing the tool to cycle.
Keep hands and body away from the discharge area of the tool. A contact arm tool may
bounce from the recoil of driving a fastener and an unwanted second fastener may be
driven possibly causing injury.
Check operation of the contact arm mechanism frequently. Do not use the tool if the arm
is not working correctly as accidental driving of a fastener may result. Do not interfere
with the proper operation of the contact arm mechanism.
Do not drive fasteners on top of other fasteners as this may cause deflection of
fasteners which could cause injury.
When working on air tools note the warnings in this manual and use extra care when
evaluating problem tools. -3-

SDN11RH TOOL SPECIFICATIONS
All screws and nuts are metric.
FASTENER SPECIFICATIONS:
This tool uses a wide range of nail sizes in lengths of 2” to 3-1/2” (50 - 90mm) and shank diameters of .113” to
.148” (2.8 - 3.3mm)
TOOL AIR FITTING:
This tool uses a 1/4” N.P.T. male plug. The inside diameter should be .275” (7mm) or larger. The fitting must be
capable of discharging tool air pressure when disconnected from the air supply. The connector socket on the air
hose should be .275” (7mm) inside diameter or larger.
OPERATING PRESSURE:
70 to 100 p.s.i.g. (4.9 to 7.0 kg/cm2). Select the operating pressure within this range for best fastener performance.
DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.
AIR CONSUMPTION:
The SDN11RH requires 7.8 cubic feet per minute of free air to operate at the rate of 100 nails per minute, at
80 p.s.i.g. (5.6 kg/cm2). Take the actual rate at which the tool will be run to determine the amount of air required.
For instance, if your nail usage averages 50 nails per minute, you need 50% of the 7.8 c.f.m. which is required to
operate the tool at 100 nails per minute.
STAN-TECH OFFERS TWO TYPES OF OPERATION FOR THIS SERIES TOOL
CONTACT TRIP
The common operating procedure on “Contact Trip” tools is for the operator to contact the work to actuate the trip
mechanism while keeping the trigger pulled, thus driving a fastener each time the work is contacted. This will allow
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
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.

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 p.s.i. (10.6 kg/cm2) 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 p.s.i. 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 p.s.i. 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 clogged filter will cause a pressure
drop which will reduce the tool’s performance.
LUBRICATION
Frequent, but not excessive, lubrication is required for best performance. Oil added through the air line connection
will lubricate the internal parts. Use Approved Air Tool Lubricant, Mobil Velocite #10, or equivalent. 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 airline 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.
COLD WEATHER OPERATION:
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 Approved WINTER FORMULA air tool lubricant or permanent antifreeze
(ethylene glycol) as a cold weather lubricant.
CAUTION: Do not store tools in a cold weather environment to prevent frost or ice formation on the tools
operating valves and mechanisms that could cause tool failure.
NOTE: Some commercial air line drying liquids are harmful to “O”-rings and seals – do not use these low
temperature air dryers without checking compatability.

The Fastener Depth Control Adjustment feature provides control of the nail drive
depth, from flush with or just above the work surface to shallow or deep
countersink.
TO ADJUST THE FASTENER DEPTH CONTROL:
DISCONNECT TOOL FROM AIR SUPPLY BEFORE
ATTEMPTING ANY PARTS DISASSEMBLY AND BEFORE
CHANGING THE WORK CONTACTING ELEMENT
ADJUSTMENT.
1. With air pressure set, drive a few fasteners
into a representative material sample to
determine if adjustment is necessary.
2. If adjustment is required, disconnect air
supply.
3. If adjustment to the drive depth is required,
measure the difference in depth between the
nail as driven in the sample material and the
desired drive. The depth control should be
changed by the same amount. To reduce the
drive depth, the work contacting element
should be lengthened. To obtain a deeper
drive, the work contacting element should be
shortened.
4. To make the adjustment, use a 10mm wrench or nut driver to loosen
the (2) elastic stop nuts on the depth control approximately 2 full
revolutions. It is not necessary to remove these nuts. Move the lower
portion of the depth control to the desired height and tighten the nuts.
Do not overtighten. Check that the work contacting element operates freely
without sticking or binding.
5. Reconnect air supply and drive a few fasteners in a sample of
material to determine if adjustment is correct. If further adjustment is
necessary, disconnect air and repeat above.
EYE PROTECTION which conforms to ANSI 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 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 American National Standards

BEFORE HANDLING OR OPERATING THIS TOOL:
I. READ AND UNDERSTAND THE WARNINGS CONTAINED IN THIS MANUAL.
II. REFER TO “TOOL SPECIFICATIONS” IN THIS MANUAL TO IDENTIFY THE
OPERATING SYSTEM ON YOUR TOOL.
1. TRIGGER OPERATION
A TRIGGER OPERATED tool requires a single action to drive a fastener. Each time the trigger is pulled the tool
will drive a fastener. The trigger operated model is intended for use only when a contact trip or sequential trip
cannot be used due to the requirements of the application.
2. CONTACT TRIP OPERATION
The CONTACT TRIP MODEL tool contains a contact trip that operates in conjunction with the trigger to drive a
fastener. There are two methods of operation to drive fasteners with a contact trip tool.
A. SINGLE FASTENER PLACEMENT: To operate the tool in this manner, first position the contact trip on
the work surface, WITHOUT PULLING THE TRIGGER. Depress the contact trip until the nose touches
the work surface and then pull the trigger to drive a fastener. Do not press the tool against the work
with extra force. Instead, allow the tool to recoil off the work surface to avoid a second unwanted fas-
tener. Remove your finger from the trigger after each operation.
B. RAPID FASTENER OPERATION: To operate the tool in this manner, hold the tool with the contact trip
pointing towards but not touching the work surface. Pull the trigger and then tap the contact trip
against the work surface using a bouncing motion. Each depression of the contact trip will cause a
fastener to be driven.
There are three available systems on STAN-TECH pneumatic tools. They are:
1. TRIGGER OPERATION 2. CONTACT TRIP OPERATION 3. SEQUENTIAL TRIP OPERATION
The operator must not hold the trigger pulled on contact trip tools except during fastening
operation, as serious injury could result if the trip accidentally contacted someone or
something, causing the tool to cycle.
Keep hands and body away from the discharge area of the tool. A contact trip tool may
bounce from the recoil of driving a fastener and an unwanted second fastener may be
driven, possibly causing injury.
3. SEQUENTIAL TRIP OPERATION:
The SEQUENTIAL TRIP MODEL contains a contact trip that operates in conjunction with the trigger to drive a
fastener. To operate a sequential trip tool, first position the contact trip on the work surface WITHOUT PULLING
THE TRIGGER. Depress the contact trip and then pull the trigger to drive a fastener. As long as the contact trip is
contacting the work and is held depressed, the tool will drive a fastener each time the trigger is depressed. If the
contact trip is allowed to leave the work surface, the sequence described above must be repeated to drive another
fastener.

BASIC TOOL OPERATION
MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use extra care
evaluating problem tools.
CAUTION: Pusher spring (constant force spring). Caution must be used when working with the spring
assembly. The spring is wrapped around, but not attached to, a roller. If the spring is extended
beyond its length, the end will come off the roller and the spring will roll up with a snap, with a
chance of pinching your hand. Also the edges of the spring are very thin and could cut. Care
must also be taken to insure no permanent kinks are put in the spring as this will reduce the
springs force.
REPLACEMENT PARTS:
STAN-TECH replacement parts are recommended. Do not use modified parts or parts which will not give
equivalent performance to the original equipment.
ASSEMBLY PROCEDURE FOR SEALS:
When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker “O”-LUBE or
equivalent on all “O”-rings. Coat each “O”-ring with “O”-LUBE before assembling. Use a small amount of oil on
all moving surfaces and pivots. After reassembly add a few drops of Approved Air Tool Lubricant through the air
line fitting before testing.
AIR SUPPLY-PRESSURE AND VOLUME:
Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of
undersize fittings and hoses, or from the effects of dirt and water in the system. Restricted air flow will prevent
the tool from receiving an adequate volume of air, even though the pressure reading is high. The results will be
slow operation, misfeeds or reduced driving power. Before evaluating tool problems for these symptoms, trace
the air supply from the tool to the supply source for restrictive connectors, swivel fittings, low points containing
water and anything else that would prevent full volume flow of air to the tool.
Stan-Tech pneumatic tools are cycled by a compressed air operated single piston design. The following
illustrations show the four functional cycles that occur when the tool is operated to drive a fastener:
