Do not directly inhale the exhaust air. Avoid expos- ing the eyes to exhaust air. The pneumatic tool’s ex- haust air can contain water, oil, metal particles and de- bris from the compressor. This can cause damage to one’s health. Pneumatic tool use and care Use the clamping devices or a vice to secure and sup- port the workpiece. Holding the workpiece by hand or against your body will not allow for safe operation of the pneumatic tool. Do not overload the pneumatic tool. Use the pneu- matic tool intended for your work. The correct pneu- matic tool will do the job better and safer at the rate for which it is designed. Do not use a pneumatic tool that has a defective On/Off switch. A pneumatic tool that cannot be con- trolled with the switch is dangerous and must be re- paired. Disconnect the air supply before making any adjust- ments, changing accessories, or when not using for extended periods. This safety measure prevents acci- dental starting of the pneumatic tool. Store idle pneumatic tools out of the reach of chil- dren. Do not allow persons unfamiliar with the pneu- matic tool or these instructions to operate the de- vice. Pneumatic tools are dangerous in the hands of untrained users. Maintain the pneumatic tool with care. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the pneumatic tool’s operation. Have damaged parts re- paired before using the pneumatic tool. Many acci- dents are caused by poorly maintained pneumatic tools. Keep cutting tools sharp and clean. Properly main- tained cutting tools with sharp cutting edges are less likely to bind and are easier to control. Use the pneumatic tool, accessories, application tools, etc. according to these instructions. Take into consideration the working conditions and the activi- ties to be carried out. This reduces the development of dust, vibrations and noise to the greatest extent. The pneumatic tool should be set up, adjusted or used exclusively by qualified and trained operators. The pneumatic tool may not be modified in any way. Modifications can reduce the effectivity of the safety measures and increase the risks for the operator. Service Have your pneumatic tool repaired only through a qualified repair person and only using original re- placement parts. This will ensure that the safety of the pneumatic tool is maintained. Safety Warnings for Compressed-air Nailers/Staplers Wear safety goggles. Always assume that the pneumatic tool is loaded with fasteners. Careless handling of the pneumatic tool can lead to unexpected shot actuation of fasteners and cause injury. When working, hold the pneumatic tool in such a manner that your head and body cannot be injured in case of sudden kickback due to a malfunction of the energy supply or from hard objects/locations in the workpiece. Never point the pneumatic tool at yourself or at per- sons close by. Unexpected actuation will expel a fas- tener, which can lead to injury. Do not actuate the pneumatic tool until firmly placed against the workpiece. When the pneumatic tool is not in contact with the workpiece, the fastener can bounce away from the fastening point and overload the pneu- matic tool. Do not work on ladders or scaffolds when the actuation system “Contact ac- tuation” is set. In particular, do not move from one fastening location to another, close boxes or enclosures, or fasten transport-securing fixtures on e.g., vehicles and wag- gons, via scaffolds, stairs, ladders or ladder-like con- structions, such as roof battens. With this actuation sys- tem, a fastener will be discharged each time when accidentally applying the pneumatic tool while the dis- charge lock-off is pressed in. This can lead to injury. Observe the conditions of the job site. It is possible that fasteners can burst through thin workpieces or be deflected when working in corners or against edges, and harm persons. Disconnect the air supply, when the fas- tener is jammed in the pneumatic tool. When the pneumatic tool is still connected to the power supply, it can accidentally be actuated when removing a jammed fasten- er. Use caution when removing a jammed or stuck fas- tener. The system can be under tension and cause the fastener to be shot or thrust out, while attempting to clear the jam. WARNING OBJ_BUCH-1038-004.book Page 13 Tuesday, November 11, 2014 2:36 PM1 609 92A 10X | (11.11.14) Bosch Power Tools 14 | English Do not use this to pneumatic tool to fasten electrical wiring. It is not suitable for fastening electrical wiring, can damage the insulation of electric cables and thus lead to electric shock and danger of fire. Never use oxygen or flammable gases as the energy source for the pneumatic tool. Flammable gases are dangerous and can cause the pneumatic tool to ex- plode. Use appropriate detectors to determine if utility lines are hidden in the work area or call the local util- ity company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage. The pneumatic tool may only be connected to lines, for which the maximal permissible pressure of the pneumatic tool cannot be exceeded by more than 10 %; for higher pressures, a pressure control valve (pressure reducer) with preceding pressure-limita- tion valve in the compressed-air line must be in- stalled. Excessive pressure leads to abnormal opera- tion or breakage of the pneumatic tool, which can lead to injury. Product Description and Specifica- tions Read all safety warnings and all instruc- tions. Failure to follow the warnings and in- structions may result in electric shock, fire and/or serious injury. Intended Use The pneumatic tool is intended for connecting work in roof- ing, encasing, battening, manufacturing wall and ceiling el- ements, wood facades, pallets, wood fences, noise-reduc- tion walls and boxes. Only the fasteners (nails, staples, etc.) specified in table “Technical Data” may be used.

Declaration of Conformity We declare under our sole responsibility that the product described under “Technical data” complies with all applica- ble provisions of the directive 2006/42/EC including its amendments and is in conformity with the following stand- ards: EN 792-13. Technical file (2006/42/EC) at: Robert Bosch GmbH, PT/ETM9, 70764 Leinfelden-Echterdingen, GERMANY Robert Bosch GmbH, Power Tools Division70764 Leinfelden-Echterdingen, GERMANYLeinfelden, 13.11.2014 Assembly Connecting the Air Supply (see figure A) Make sure that the pressure of the compressed-air system is below the maximum permitted rated pressure of the pneumatic tool. Firstly, set the air pressure to the lower value of the recommended rated pressure (see “Technical Data”). When in doubt, check the pressure at the air inlet with a pressure gauge with the pneumatic tool switched on. For maximum performance, the values for the supply-air hose 17 (connection thread, maximum operating pres- sure, inner hose diameter, maximum hose length; see “Technical Data”) must be observed. The compressed air supplied should be free of foreign ma- terial and moisture to protect the tool from damage, con- tamination, and the formation of rust. All fittings, connecting lines and hoses must be dimen- sioned for the pressure and the required air volume. Avoid restrictions in the air supply, e.g., from pinching, kinking, or stretching!

(See “Emptying the Magazine”, page 15) For the following worksteps, a fastener can be dis- charged when interior parts of the pneumatic tool are not in the starting position due to repairs, maintenance or transport. – Connect the air connector 6 with a supply-air hose 17 equipped with an air-connection coupling 16. – Check the proper function by placing the outlet 13 or the rubber workpiece protector 1 of the pneumatic tool onto a piece of scrap wood or wood material, and dis- charging once or twice. Loading the Magazine Disconnect the air supply before making any adjustments, changing accessories, or placing the pneumatic tool aside. This safety measure prevents accidental start- ing of the pneumatic tool. Use only original Bosch accessories (see “Technical Data”). The precision parts of the pneumatic tool such as the magazine, the outlet and the shot duct are matched to Bosch staples, nails and brads. Other man- ufacturers use other steel qualities and sizes. Using fasteners not permitted, can damage the pneu- matic tool and cause injuries. While loading the magazine, hold the pneumatic tool in such a manner that the outlet 13 is not pointed at your own body or at other persons. GTK 40 (see figures B1–B2) – Pull back the magazine slider 11 until the button of mag- azine-slider lock 7 fully engages. – Clean and lubricate the magazine slider 11 as required and make sure that the magazine 8 is not dirty/soiled. – Place a fitting strip of staples 18 over magazine 8. The staple heads must face completely flush against the surface of the magazine and the staple strips must move easily in the magazine. – Lightly pull back magazine slider 11 and press the but- ton of magazine-slider lock 7 inward. – Carefully guide the magazine slider to the front until it touches the staple strip. Note: Do not let the magazine slider snap back without guiding it. Otherwise, the magazine slider could become damaged, and there is danger of your fingers being caught or pinched. GSK 50 (see figures C1–C2) – Press magazine lock 14 and at the same time pull maga- zine 8 toward the rear to the stop. – Clean and lubricate magazine rail 20 as required. – Insert a fitting nail strip 19. If possible, the nail tip should touch the magazine rail

– Slide the nail strip in the magazine all the way to the front. – Insert the magazine until magazine lock 14 engages again. Refill the magazine when the red bars of refill indicator 15 can be seen halfway. Operation Actuation systems The pneumatic tool can be operated with two different ac- tuations systems: – Single actuation with safety run With this actuation system, the discharge lock-off 2 must first be firmly pressed against the workpiece. A fastener is not discharged until the trigger 10 is pulled. Afterwards, further discharging procedures can only be actuated, when the trigger and the discharge lock-off have first been set back to the starting position. – Contact actuation With this actuation system, the trigger 10 must be pulled first. A fastener is always discharged when the discharge lock-off 2 is firmly pressed against the work- piece while the trigger is pressed. This enables a higher working speed to be achieved. The actuation system is set via the selector switch 9. Starting Operation Disconnect the air supply before making any adjustments, changing accessories, or placing the pneumatic tool aside. This safety measure prevents accidental start- ing of the pneumatic tool. Working with Single Actuation (see figure D) – Press selector switch 9 inward and at the same time piv- ot it to the bottom position until it engages. The actuation system “single actuation” is set. – Release the selector switch 9 again. – Firmly position the outlet 13 or the rubber workpiece protector 1 on the workpiece until discharge lock-off 2 is pressed in completely. –Afterwards, briefly press trigger 10 and release again. A staple (GTK 40) or a brad (GSK 50) is discharged. – Allow the pneumatic tool to bounce back from the work- piece. – For another driving procedure, completely lift the pneu- matic tool from the workpiece and position it firmly at the next desired location. Working with Contact Actuation (see figure E) – Press selector switch 9 inward and at the same time piv- ot it to the upper position until it engages. The actuation system “contact actuation” is set. – Release the selector switch 9 again. – Press and hold the trigger 10. – Firmly position the outlet 13 or the rubber workpiece protector 1 on the workpiece until discharge lock-off 2 is pressed in completely. A staple (GTK 40) or a brad (GSK 50) is discharged. – Allow the pneumatic tool to bounce back from the work- piece. – For another driving procedure, completely lift the pneu- matic tool from the workpiece and position it firmly at the next desired location. – Move the pneumatic tool uniformly over the workpiece by lifting it off and applying it again. Each time when applying the pneumatic tool while the discharge lock-off is pressed in, a staple (GTK 40) or a brad (GSK 50) is discharged. – As soon as the desired amount of staples (GTK 40) or brads (GSK 50) have been driven in, release trigger 10 again. Working Advice Disconnect the air supply before making any adjustments, changing accessories, or placing the pneumatic tool aside. This safety measure prevents accidental start- ing of the pneumatic tool. Check the proper function of the safety and actuation de- vices, and the tight seating of all screws and nuts each time before using. Disconnect a defective or not properly operating pneumat- ic tool immediately from of the air supply and contact an authorised service agent for Bosch power tools. Do not perform any incorrect manipulations on the pneu- matic tool. Do not disassemble or block any components of the pneumatic tool, such as the discharge lock-off. Do not carry out “emergency repairs” with unsuitable means. The pneumatic tool is to be maintained regularly and properly (see “Maintenance and Cleaning”, page 16). Avoid any weakening and damage whatsoever of the pneu- matic tool, e.g., through: – Imprinting or engraving, – Retrofitting measures not approved by the manufactur- er, – Guiding along templates manufactured of hard material, e.g. steel, – Dropping on or sliding over the floor, – Using as a hammer, –Applying any kind of force. Make sure to check whatever is below or behind your work- piece. Do not shoot staples (GTK 40) or brads (GSK 50) in- to walls, ceilings or floors, when persons are behind them. The fasteners can burst through the workpiece and injure someone. Do not shoot a staple (GTK 40) or brad (GSK 50) on al- ready driven-in fasteners. This could cause the fastener to deform, the fasteners could become jammed or the pneu- matic tool could move uncontrolled. When the pneumatic tool is used under cold ambient con- ditions, the first staples (GTK 40) or brads (GSK50) are driven in slower than usual. Once the pneumatic tool has warmed up during working, normal operating speed will be regained. Avoid blank shots in order to reduce the wear of the impact striker. For longer work breaks or after finishing work, disconnect the pneumatic tool from the air supply and empty the mag- azine. Emptying the Magazine GTK 40 – Pull back the magazine slider 11 until the button of mag- azine-slider lock 7 fully engages. – Remove staple strip 18. – Lightly pull back magazine slider 11 and press the but- ton of magazine-slider lock 7 inward. – Carefully guide the magazine slider to the front until it touches the beginning of the magazine. Note: Do not let the magazine slider snap back without guiding it. Otherwise, the magazine slider could become damaged, and there is danger of your fingers being caught or pinched. GSK 50 –Press magazine lock 14 and at the same time pull maga- zine 8 toward the rear to the stop. – Remove the nail strips 19. – Insert the magazine until magazine lock

engages again. Adjusting the Depth Stop (see figure F) The driving depth of the staples (GTK 40) or brads (GSK 50) can be set with thumbwheel 3. –Empty the magazine 8. (See “Emptying the Magazine”, page 15) – Nails are driven in too deeply: To reduce the driving depth, turn thumbwheel 3 in anti- clockwise direction.
