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.

MODEL IDENTIFICATION:

Refer to Operation Instructions on page 7 before proceeding to use this tool.

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

Institute, ANSI Z87.1-1989 and provide both frontal and side protection. NOTE: Non-side

shielded spectacles and face shields alone do not provide adequate protection.

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:
