General Pneumatic Tool Safety Rules

ALL USERS AND EMPLOYERS/OWNERS MUST READ AND UNDERSTAND ALL INSTRUCTIONS IN THIS MANUAL BEFORE OPERATING OR MAINTAINING THIS TOOL. Failure to follow all instructions listed below

may result in electric shock, fire, serious personal injury or death.

SAVE THESE INSTRUCTIONS

Work Area

Ke e p yo u r wo r k ar e a cl e a n an d we l l li t . Cl u t tered

benches and dark areas increase the risks of accidents, electric shock, fire, and injury to persons.

Do not operate pneumatic tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. The tool is able to create sparks

which may ignite the dust or fumes. Never use the tool in sites containing lacquer, paint, benzine, thinner, gasoline, gases, adhesive agents, and other materials which are combustible or explosive.

Keep bystanders, children, and visitors away while operating a pneumatic tool. Distractions may cause loss

of control of the tool. Fragments of fasteners may cause injury to bystanders.

Never engage in horseplay with the tool. Respect the tool as a working implement.

Personal Safety

Do not remove, tamper with, or otherwise cause the tool operating controls to become disabled or inoperable.

This will cause the tool to work irregularly and may result in the risk of injury.

Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long

hair can be caught in moving parts and increases the risk of injury.

Always wear eye and ear protection when using this tool. Use additional personal protective equipment as appropriate when operating this tool. Operators and

others in work area must wear safety glasses with side shields and make sure all other personnel in the work area wear safety glasses. Safety glasses must conform to the requirements of American National Standards Institute, ANSI Z87.1 and provide protection against flying particles both from the front and side. Prolonged exposure to high intensity noise is able to cause hearing loss. Dust mask, non - s k id sa f e t y sh o e s , ha r d hat and o ther p e r s o nal pro t e ctive e q u ipment, must be u s e d fo r appr o p riate conditions.

Keep handles dry, clean and free from oil and grease.

Slippery hands cannot safely control the tool.

Avoid directing exhaust air from the tool into your or a bystander face and eyes. Exhaust air from a tool can

contain water, oil, metal particles or contaminants from the compressor, which can be blown into the eyes or cause serious injury. Use adjustable air vent to direct exhaust to blow exhaust air away from user.

Stay alert. Watch what you are doing, and use common sense when operating a pneumatic tool. Do not use the tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating the

tool may result in serious personal injury.

Avoid unintentional operation. While connecting air supply do not depress trigger. Do not carry the tool with

your finger on the trigger or connect the tool to the air supply with the switch “on.”

Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control

of the tool in unexpected situations.

Make sure air hose is free of snags and obstructions. Do not at t a ch an air hose or tool to your bo d y .

Entangled or snarled hoses can cause a loss of balance or footing in addition to unintentional tool operation. Attach the hose to the structure to reduce the risk of loss of balance if the hose shifts.

Tool Use and Care

Use this tool and accessories in accordance with the instructions. Tools and accessories must be used for the

purpose for which they are designed. Use of the pneumatic tool for operations different from what's described in this manual can result in a hazardous situation.

Use only accessories that are recommended by BOSCH for y our parti cular mode l. Accessorie s t hat ma y be

recom mended for a pa rti cular m odel tool ma y not be suitable on other model tools and may result in personal injury.

Before each use, inspect the tool. Do not operate if any portion of the tool is loose, missing, damaged, malfunctioning, disconnected or altered. I f the tool

appears to be operating unusually and/or making strange noises, stop using it immediately and contact your local service center. There is a risk of bursting if the tool is damaged.

Do no t fo r c e tool. Use the co rr e c t too l for your application. The correct tool will do the job better and safer

at the rate for which it is designed.

Do not operate the tool with any power source other than that sp e c i f ie d in th e tool operating / s a f e t y instructions. Use of alternative power sources may result

in malfunctions of the tool and the power source which may lead to serious injury of you or others in your surroundings.

Di scon nect to ol f rom air su pply wh en n ot i n use.

Leaving the tool unattended with the air supply connected can result in unintentional operation of the tool by users unfamiliar with tool.

WARNING

BM 2610957380 02-09:BM FNS250-16 06-09 6/17/09 8:05 AM Page 2

Disconnect the tool from the air source before making ad j ustme n ts, c leari ng jams, unload ing f astene rs, leaving the work area, performing tool maintenance or storing the tool. Such precautionary safety measures

reduce the risk or unintentional tool operation.

Never carry the tool by the hose. The tool, air fittings and the air hose may become damaged.

Use clamps or another practical way to secure and support the work piece to a stable platform. Holding

work by hand or against your body is unstable and may lead to loss of control or personal injury.

The correct pressure is the lowest pressure that will do the job. Always follow recommendations for the particular

tool.

Maintain tools with care. Properly maintained tools are less likely to break and cause injury. Any alteration or modification is a misuse and may result in a dangerous condition.

Service

Maintenance performed by unauthorized personnel may result in misplacing of the internal components which could cause serious hazard. We recommend that all tool

service be performed by a BOSCH factory service center or authorized BOSCH service station.

Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal components may be misplaced or safety components may be improperly mounted. Certain cleaning agents such as gasoline, carbon

tetrachloride, ammonia, etc. may damage plastic parts and o-rings.

Whe n serv i c ing th e to o l , us e only reco m m ended BOSCH replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized

parts or failure to follow Maintenance Instructions can cause a risk of injury.

Use only the air tool lubricants supplied with the tool or specified by BOSCH. Do not use other lubricants as they

may damage the tool. See the "Lubrication" section for a list of recommended air tool lubricants.

Replace missing or damaged warning labels. Refer to tool schematic for correct placement and part number.

Keep the tool clean and lubricated. Clean the tool at least daily and lubricate as required. Never operate a dirty or malfunctioning tool.

When not in use, store the tool out of reach of children and other personnel unfamiliar with tool operation.

When not in use, the tool should be disconnected and stored in a dry place. Keep out of reach of children. Lock the storage area. Tools are dangerous in the hands of users unfamiliar with the tool.

Air Source

Never use oxygen or other bottled gases as a power source. Explosion may occur. Combustible gases and other

bottled gases are dangerous and may cause the tool to explode.

Use only clean, dry, regulated, compressed air within the rated pressure range marked on the tool. Do not exceed maximum recommended air pressure marked on the tool. Verify prior to using the tool that the air source

has been adjusted within the rated air-pressure range. Be sure the air pressure gauge is operating properly and check it at least twice a day. Tools operated in excess of their maximum pressure rating may operate abnormally or burst, resulting in personal injury.

Never connect the tool to an air source that is capable of producing air pressure exceeding 200 PSI. Excessive

pressure can cause abnormal operation or cause the tool to burst, resulting in personal injury.

Do not abuse the air hose. Protect all hoses from kinks, restrictions, solvents or sharp objects. Keep air hose away from heat, oil, sharp edges or moving parts.

Replace damaged hoses immediately. Damaged hoses can burst or whip around.

Ch eck all fitti ngs, hos es, pipes , connec tion s an d compressor before each use of this tool. Repair or replace damaged or leaking hoses and connections immediately. Damage to a hose or connection can cause a

pressure hose to break and whip around the work area, and can lead to injury.

Safety Rules for Pneumatic Nailer Tools

Alway s assume t he tool conta ins na ils. Check th e

magazine for nails that may be left in the tool, even if you think the tool is empty or disconnected.

Never point the tool at yourself or others in the work area. Always assume the tool contains nails. If nails are

accidentally fired, it may result in injury. The tool is not a toy and should not be used like one.

Remove finger from the trigger when not driving nails. Always carry the tool by the handle only. Removing your

finger from the trigger when not operating the tool reduces the risk of unintentionally firing a nail and injuring yourself or someone else.

Do not disable or remove the work contact element.

This tool is equipped with a safety mechanism, the work

contact element, to reduce the risk of accidental firing. Disabling this component can result in unintentional firing.

Do not use the tool unless the work contact element is working properly. If the work contacting element is not

functioning correctly, the tool can fire unexpectedly.

Never use non relieving couplers and/or female quick disconnect couplings on the tool. Non relieving couplings

and female couplings will trap high pressure air in the tool when the air line is disconnected. This will leave the tool charged with enough air after it has been disconnected to drive a nail. Only MALE pneumatic type air connectors should be fitted to the tool, so that high pressure air in the tool is vented to atmosphere as soon as the air line is disconnected.

BM 2610957380 02-09:BM FNS250-16 06-09 6/17/09 8:05 AM Page 3

Follow all recommendations for sizes of hoses, fittings a

nd other compressed air accessories. Improperly sized

or fitting components may result in the risk of injury or property damage.

heck air supply lines for restrictions before adjusting

the t ool. Ai r v olum e is a s impor tant as air p ressure .

Restricted air flow will prevent the tool from operating as d

esigned, resulting in slow operation, nail misfeeding or

reduced driving power.

Always load nails into the tool's magazine before the air s

upply is connected. Connecting the air supply after

loading nails reduces the risk of unintentionally driving a nail and injuring yourself or someone else.

When loading nails ensure that nails are parallel with nose of tool. If nails are not parallel with nose the tool will

misfire and nails can be deflected, cause the tool to react in an unexpected manner, and damage the tool.

When loading the tool's magazine, check that the nail follower slides smoothly by pulling with finger. If not

smooth, nails can be driven at irregular angle.

Use only the nails meeting the criteria listed in the “Spe c i f i c a t i o n ” se c t i o n of t h i s manual. Nails n o t

id entifie d for use with th is tool ca n cause the t ool to malfuncti on and res ult in the risk of i njury and/or tool damage.

Do not connect the air supply when the trigger or work contact element is depressed. Keep the tool pointed

do wnwa rd, awa y from yourself a nd b ysta nder s when connecting the hose to reduce the risk of accidental nail firing.

Keep hands and feet away from work contact element of the tool during use. Never place your hands or feet

closer than 8 inches (200 mm) to the work contact element of the tool. Nails can be deflected by the work piece or driven away from the point of entry.

Choice of triggering methods is important; understand the operating characteristics of each option. There are

two possible firing modes; “sequential firing” and “bump firing.” Read and under stand secti on titled “Actuation Systems” for details of each mode.

Do not use a frozen tool. Allow tool to thaw before using. Moisture frozen in the tool may impede internal components resulting in the risk of injury and/or tool damage.

Operate the tool only when properly positioned on the work piece. If the tool is not held properly on the work

piece the nail can be deflected or the tool can react in an unexpected manner.

Use sufficient grip to maintain control of the tool while allowing tool to recoil away from work surface as nail is driven. Do not attempt to prevent the recoil by holding the tool with excessive force against the work piece.

The tool will recoil as the nail is driven. This is normal function for the tool. Restriction to the recoil can result in second nail being driven when the tool is in “bump firing” mode.

Use caution when operating the tool in confined areas.

If the work contact element is allowed to re-contact the work surface before trigger is released, an unwanted nail will be fired if the tool is set in “bump firing” mode.

In order to avoid undesirable double fire , take the f

ollowing actions when the tool is in the following firing

modes:

Sequential firing:

. Ensure trigger is in sequential fire mode.

2. Pull the trigger firmly and release.

Bump firing:

1. Do not p r es s the to o l against th e wood wi t h excessive force.

2. Allow the tool to separate from the wood as it recoils after nailing.

Never drive nails near flammable materials. Some types

of nails can spark out of the nose during driving operation.

Know what is behind your work piece. Do not fire nails into walls or floors without assuring the area on the opposite side is clear. A nail could travel through the work

piece, striking someone.

Do not drive a nail on top of another nail. This could cause the nail to be deflected or the tool to react in an unexpected manner.

Do not attempt to drive nails at a steep angle. This could cause the nail to be deflected or the tool to react in an unexpected manner.

Use care when nailing thin material or when working near the edges and corners of the work piece. Nails may

driv e throug h or away from the work piece a nd injure yourself or someone else. Be aware that the nail may follow the grain of the wood causing it to protrude unexpectedly from the side of the work material. Drive the nails perpendicular to the grain.

Do not drive nails into walls, floors or other work areas without knowing what may be damaged by the driven nails. Nails driven into live electrical wires, plumbing, gas

piping, or ot h e r types of ob s t r u c t i o n s can result in electrocution, explosion, personal injury and/or property damage.

Make sure the pressure of the compressor is adjusted so that nails are driven flush into the work piece and not pushed completely through. The correct pressure is

the lowest pressure that will do the job.

Keep face and body parts away from back of the top cap when working in restricted areas. Sudden recoil can

result in impact to the body especially when nailing into hard or dense material.

Handle tool carefully. Because of high air pressure in the tool, do not drop the tool or strike the tool against hard surfaces; and do not scratch, stamp, nor engrave signs on the tool. The tool may burst.

Always disconnect tool from air supply and remove nails from magazine before leaving the area or passing tool to an o t h e r operator. T h i s avoids th e ri s k of

unintentional operation.

Do not disconnect air hose from the tool with finger on trigger or the work contact element depressed. The tool

can fire when reconnected to air supply.

Operation

Assembly / Installation

Follow the instructions below t o p repare your tool for operation.

1. All tool operators and their immediate supervisors must

become familiar with the operator safety instructions before operating the tool. The instructions begin on page 3 of this manual.

2. In c l u d ed with each t o o l are o n e c o p y of t h e s e

Operating/Safety Instructions and one copy of the Tool Schematic. Keep these publications for future reference.

3. Install a filter, regulator, lubricator unit and moisture trap

on yo ur air delive ry s ystem p er t he manu fact urer 's instruction s for these devices. Additionally, install a pressure g a u g e a s close a s practical to the to o l , preferably within ten feet.

4. Select hoses with a minimum inner diameter of 3/8 inches

and a maximum length of 100 feet.

To reduce the risk of injury from a hose bursting, select hoses that are rated at

least 200 PSI.

5. Select fittings that are appropriately sized for the selected

hoses. The tool and air hose must have a hose coupling such that all pressure is removed from the tool when the coupling joint is disconnected.

Never use non re l i e v i n g co u p l e r s and/or female q u i c k di s c o n n e c t

couplings on the tool. Non relieving couplings and

female couplings will trap high pressure air in the tool when the air line is disconnected. This will leave the tool charged with enough air after it has been disconnected to drive a nail. Only MALE pneumatic type air connectors should be fitted to the tool, so that high pressure air in the tool is vented to atmosphere as soon as the air line is d

isconnected.

6. Set the regulator at the air delivery system to a PSI that falls within the tool's operating range of 60 to 120 PSI. The correct pressure is the lowest pressure that will do the job.

7. If the o pera tor is w orki ng a t a be nch or t able , it is recommended to run the air line underneath the bench. A small tray under the bench top can hold the nail supply and the tool when not in use.

Actuation System

Your tool is equipped with two devices that require actuation before the tool will fire, the work contact element and the finger trigger. There are two selectable modes, built into the trigger, that determine how the tool fires nails.

“Sequential” Firing Mode: In “sequential” firing mode, there is a predetermined sequence required to fire a nail. The work contact element must first be depressed against the work piece. A nail will then fire when the trigger is depressed. To fire another faster, the work contact element must be removed from the work piece, the trigger must be released. The sequence can then be repeated.

“Bump” Firing Mode: In “Bump” firing mode, nails can be fired each time the work contact element is depressed with th e tri g ger d e pressed . Wi t h th e tri g ger c o ntinuou s ly depressed, a nail will fire each time the work contact element is depressed against the work piece. This allows for nails to be fired at a faster rate.

Each mode is described in detail in the “Firing Modes” section of this manual.

Understand t h e differences be t w e e n actuation modes for this tool. Using the

tool in an inappropriate mode may cause tool to react in an unexpected manner and may result in personal injury.

Verify the setting of the Selectable trigger switch before using the tool. Using the tool

before verifying the actuation mode may cause tool to react in an unexpected manner and may result in personal injury.

Lubrication

If the tool is not used with an in-line lubrication system on the air supply it is necessary to periodically lubricate the tool with air tool lubricant.

nder low use, lubricate once a day. Under heavy use, lubricate twice a day. To lubricate, insert 2-3 drops of lubricant into the air supply fitting attached to the tool handle, see figure 2. Using to much oil will cause it to collect i

n the tool and be noticeable in the exhaust.

Use only the air tool lubricants supplied with the tool or specified by BOSCH. Do

not use other lubricants as they may damage the tool.

Do not use detergent oil, WD-40, transmission fluid, motor oil, or other lubricants not specifically designated as air tool lubricants. These lubricants will cause accelerated wear to the seals, o-rings, and bumpers in the tool, resulting in poor tool performance and frequent maintenance.

BOSCH recommended lubricants: 10W Pneumatic Tool Oil, Fuchs Air Lube 10W/NR.

Nail Loading

Always load nails into the tool's magazine before the air su p p l y is connected.

Connecting the air supply after loading nails reduces the risk of unintentionally driving a nail and injuring yourself or someone else.

When loading the tool's magazine, check that the nail follower slides smoothly by

pulling with finger. If not smooth, nails can be driven at

irregular angle.

1. Insert appropriate collated nail strips into loading slot in

back of magazine, see figure 3. See tool specifications to determine appropriate nail sizes and angles.

2. Orient a strip of approved nails with the tips pointed down,

and align the head of the nail with the top “T” portion of the slot. Insert nails fully into magazine making sure that the last nail in the strip slides past the Nail Hold Back Spring, see figure 4.

Note: The tool features a nail follower lockout that will prevent the tool from firing when there are zero nails left in the magazine. The tool will not allow the work contact element to be depressed when there are no nails in the tool.

Use only the nails meeting the criteria listed in the “Specification” section of this

manual. Nails not identified for use with this tool can cause

the tool to malfunction and result in the risk of injury and/or tool damage.

3. This tool uses a spring loaded bypass lever in order to

load and unload the nails. Once the nails are properly inserted, pull the follower completely to the back of the magazine, pressing aga ins t the by pas s l eve r of the follower, see figure 5.

4. Once the follower hits the back of the magazine, allow the

follower to slide forward and engage the nails, pushing them to the nose of the tool, see figure 6.

Watch for pinch points with the follower. Never place any part of your body in a

pinch point area. When loading nails consider where your

hand is located. If it is within a pinch point, strongly consider an alternative position. Injuries occur when hands or fingers are between moving and stationary parts during the pinching movement.

Connecting Air Supply

Never use oxygen or other bottled gases as a power source. Explosion may occur.

Combustible gases and other bottled gases are dangerous and may cause the tool to explode.

Never connect the tool to an air source that is capable of producing air pressure

exc e e d i n g 200 PSI. E x cessive p r e s s u re ca n cause

abnormal operation or cause the tool to burst, resulting in personal injury.

Use only clean, dry, regulated compressed air within the pressure range as marked on the tool. The correct pressure is the lowest pressure that will do the job.

Before connecting the tool to the air supply, check the air compressor regulator gauge to be sure it is functioning properly, and that the air pressure is within the operational range of the tool, 60-120 psi.

Do not exceed maximum recommended air pressure marked on the tool. Verify

prior to using the tool that the air source has been adjusted within the rated air-pressure range. Be sure the air pressure gauge is operating properly and check it at least twice a day. Tools operated in excess of their maximum pressure rating may operate abnormally or burst resulting in personal injury

To connect the tool to the compressor only use pneumatic air hoses that meet the following criteria:

• Minimum hose pressure rating, 200 psi

• Minimum hose inner diameter, 3/8 in.

• Maximum hose length, 100 ft.

To connect the air supply:

1. Snap the air hose onto the quick connector, see figure 7.

2. Check for air leakage. If leakage is noted, cease using the

tool immediately and contact your BOSCH service center.

3. Be sure the air pressure gauge is operating properly and

check it at least twice a day.

Firing Modes

The tool is equipped with a trigger that can select one of two firing modes.

“Sequential” Firing Mode:

To use the tool to drive nails in this actuation mode, the work contact element and trigger must be used in a specific order:

1. Press and turn the selectable fire mode switch in the

downwards position. On the trigger, the firing mode indicator should be pointing at the single nail icon, see figure 8.

2. The work contact element must be completely depressed

by placing the nose of the tool against the work piece, see figure 9.

3. The trigger must be pulled firmly and then released, see

figure 9.

4. The tool must be allowed to recoil away from the work

piece.

To continue operation in a separate location, move the tool along the wo rk piece, repeating steps 2 through 4 as required.

“Bump” Firing Mode:

To use the tool to drive nails in this actuation mode the work contact element and trigger can be actuated in any order.

1. Press and turn the selectable fire mode switch in the

upwards position. On the trigger the actuation mode indicator should be pointing at the multi-nail icon, see figure 10.

2. Pull and hold the trigger with the tool off the work piece.

3. Press the work contact element against the work piece. A

nail will be driven, see figure 11.

4. The tool must be allowed to recoil away from the work
