   • Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Safety Rules for Cordless Drill/Drivers

• Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
• Use the auxiliary handle(s). Loss of control can cause personal injury.
• Brace the tool properly before use. This tool produces a high output torque and without properly bracing the tool during operation, loss of control may occur resulting in personal injury.
•  Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory or fasteners may contact hidden wiring. Cutting accessories or fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.
• Do not drill, fasten or break into existing walls or other blind areas where electrical wiring may exist. If this situation is unavoidable, disconnect all fuses or circuit breakers feeding this worksite.
• Always wear safety goggles or eye protection when using this tool. Use a dust mask or respirator for applications that generate dust.
• Use thick cushioned gloves and limit the exposure time by taking frequent rest periods. Vibration caused by hammer-drill action may be harmful to your hands and arms.
• Secure the material being drilled. Never hold it in your hand or across legs. Unstable support can cause the drill bit to bind causing loss of control and injury.
• Disconnect the battery pack from tool before making any assembly, adjustments or changing accessories. Such preventive safety measures reduce the risk of starting the tool accidentally.
• Position yourself to avoid being caught between the tool or side handle and walls or posts. Should the bit become bound or jammed in the work, the reaction torque of the tool could crush your hand or leg.
• If the bit becomes bound in the workpiece, release the trigger immediately, reverse the direction of rotation and slowly squeeze the trigger to back out the bit. Be ready for a strong reaction torque. The drill body will tend to twist in the opposite direction as the drill bit is rotating.
• Do not grasp the tool or place your hands too close to the spinning chuck or drill bit. Your hand may be lacerated.
• When installing a drill bit, insert the shank of the bit well within the jaws of the chuck. If the bit is not inserted deep enough, the grip of the jaws over the bit is reduced and the loss of control is increased.
• Do not use dull or damaged bits and accessories. Dull or damaged bits have a greater tendency to bind in the workpiece.
• When removing the bit from the tool avoid contact with skin and use proper protective gloves when grasping the bit or accessory. Accessories may be hot after prolonged use.
•  Check to see that keys and adjusting wrenches are removed from the drill before switching the tool “ON”. Keys or wrenches can fly away at high velocity striking you or a bystander.
• Do not run the tool while carrying it at your side. A spinning drill bit could become entangled with clothing and injury may result.

Safety instructions when using long drill bits

• Never operate at a higher speed than the maximum speed rating of the drill bit. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
• Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
• Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend causing breakage or loss of control, resulting in personal injury.

Additional Safety Warnings

• GFCI and personal protection devices like electrician’s rubber gloves and footwear will further enhance your personal safety.
• Do not use AC-only rated tools with a DC power supply. While the tool may appear to work, the electrical components of the AC rated tool are likely to fail and create a hazard to the operator.
• Keep handles dry, clean and free from oil and grease. Slippery hands cannot safely control the power tool.
• Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted. Certain cleaning agents such as gas-line, carbon tetrachloride, ammonia, etc. may damage plastic parts.
• Ensure the switch is in the off position before inserting the battery pack. Inserting the battery pack into power tools that have the switch on invites accidents.

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well-ventilated area, and work with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.

Your tool is equipped with a Variable Speed Trigger Switch 11. The tool can be turned “ON” or “OFF” by squeezing or releasing the trigger. The speed can be adjusted from the minimum to maximum nameplate RPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease the speed.

Forward/Reversing Lever & Trigger Lock

(Fig. 5)

• After tool use, lock trigger in the “OFF” position to help prevent accidental starts and accidental discharge.
• Do not change the direction of rotation until the tool comes to a complete stop. Shifting during the rotation of the chuck can cause damage to the tool.
• Your tool is equipped with a Forward/Reversing Lever and Trigger Lock 10 located above the trigger. This lever was designed for changing direction of rotation of the bit, and for locking the trigger in an “OFF”
• position.
• For forward rotation, (with chuck pointed away from you) move the lever to the far left.
• For reverse rotation, move the lever to the far right.
• To activate the trigger lock, move the lever to the center-off position.

Gear Shifting

(Fig. 6)
Your tool is equipped with two separate gear ranges, low gear 1 and high gear 2. Low gear provides high torque and slower drilling speeds for heavy-duty work or for driving screws. High gear provides faster speeds for drilling lighter work. To change speeds, slide the Gear Shifter 4 to the high 2 or low position 1.

ATTENTION : If your tool appears to be running, but the chuck will not turn, check to make sure the gear shifter is pushed fully into desired setting.

Mode Selector Ring

• To remove battery pack: press the Battery Pack Release Button 7 and slide the battery pack towards the front of the tool. Press the battery pack release button again and slide the battery pack completely out of tool housing (Fig. 10).

Temperature Overload Protection

Avoid using battery-operated tools continuously, for long periods of time, while subjecting the tool to overload conditions, such as drilling with large diameter accessories into hard materials. Using battery-powered tools at extreme loads may cause the battery to exceed its allowable operating temperature range. When the battery exceeds normal operating temperature caused by overload, the speed of the tool may be reduced and the tool may appear to lose power. To regain the tool’s full performance, the battery must be allowed to cool, until the operating temperature returns to normal.

User Interface

(Fig. 11)
STATUS INDICATOR LED
The LED bar at the top of the user interface illuminates in various colors to help the user identify the status of the tool.

• When the status indicator LED 8a is green the tool and battery pack are operating normally and temperatures are ok.
• If the indicator changes to yellow it means that the tool or battery temperatures have risen to a critical level. It is recommended to allow the tool to cool down.
• If the indicator turns red the tool will shut off to protect itself and/or the battery pack from an overheating situation.
• The status indicator LED 8a will also blink blue when the precision clutch override 8e or KickBack Control 8c buttons are held for 7 seconds. This will reset the tool settings to factory default.

KICKBACK CONTROL (RAPID SHUT-OFF)

• To ensure better control of the tool during operation, this tool is design to shut off while in use if a sudden or unexpected bind up situation occurs. Bind-up occurs when the bit gets jammed during operation, which forces the bit to stop spinning abruptly. If this occurs, the tool will shut down and the Kick-Back Control will be indicated by flashing LED lights on the tool.
• KickBack Control can be turned off by the user. Button 8c on the user interface 8 will toggle the feature on and off. Status is indicated with “On” and “Off” LEDS 8b on the User Interface 8. If the power tool is not used for longer than 5 minutes, or if the battery is removed, KickBack Control automatically turns back on.
• Please note that the indicator light may not be visible from all directions or in bright sunlight.
• When the switch trigger is pressed, operator is notified about the KickBack Control.

PRECISION CLUTCH OVERRIDE
This tool features an adjustable clutch with out-put torque increasing as the clutch ring is rotated through the settings from 1 to 20. By default, at a given torque setting, the tool senses when the clutch begins to slip, and automatically shuts off the motor thereby reducing wear and tear on the clutch as well as the resulting noise. This is what we call precision clutch.
This automatic motor shut-off can be overridden by pressing the “P-Clutch” button 8e on the foot of the tool so that the “off” indicator 8f lights up. In this mode, the motor will continue to run whenever the trigger is pressed regardless of any clutch slippage allowing for small turns of the screw.

BUILT-IN LED WORK LIGHT
Your tool is also equipped with an LED light 8d that turns on automatically when the switch is activated, for better visibility when drilling/drilling. The light turns off automatically a short time after the trigger is released. You can adjust this time frame using Bosch Tool Box app. See “Connectivity” section.

Operating Tips

Before using an accessory, be certain that its maximum safe operating speed is not exceeded by the nameplate speed of the tool. Do not exceed the recommended accessory diameter.

Driving Nuts and Bolts
Variable speed control must be used with caution for driving nuts and bolts with socket set attachments. The technique is to start slowly, increasing speed as the nut or bolt runs down. Set the nut or bolt snugly by slowing the drill to a stop. If this procedure is not followed, the tool will have a tendency to torque or twist in your hands when the nut or bolt seats.

Drilling
You will extend the life of your bits and do neater work if you always put the bit in contact with the work before pulling the trigger. During the operation, hold the tool firmly and exert light, steady pressure. Too much pressure at low speed will stall the tool. Too little pressure will keep the bit from cutting and cause excess friction by sliding over the surface. This can be damaging to both tool and bit.

Drilling with Variable Speed
The variable speed trigger allows you to slowly increase RPM. By using a slow starting speed, you are able to keep the bit from “wandering”. You can increase the speed as the bit “bites” into the work by squeezing the trigger.

Driving with variable speed
Variable speed drills will double as a power screwdriver by using a screwdriver bit. Prior to driving screws, pilot and clearance holes should be drilled. Place the threaded end of the screw in the pilot or clearance hole and start driving the screw slowly, increasing the speed as the screw runs down. Set the screw snugly by slowing to a stop.

Fastening with Screws
The procedure shown in Fig. 12 will enable you to fasten materials together using your drill without stripping, splitting or separating the material.

• First, clamp the pieces together and drill the hole 2/3 the diameter of the screw. If the material is soft, drill only 2/3 the proper length. If it is hard, drill the entire length.
• Second, unclamp the pieces and drill the hole in the top piece of wood again to the same diameter as the shank of the screw.
• Third, if flat head screw is used, countersink the hole to make the screw flush with the surface. Realign the holes on the two pieces and ap-ply even pressure when driving the screw. The screw shank clearance hole in the first piece allows the screw head to pull the pieces tightly together.
• The adjustable screw drill accessory will do all of these operations quickly and easily. Screw drills are available for screw sizes No. 6, 8, 10 and 12.

Drill Bits

• Always inspect drill bits for excessive wear. Use only bits that are sharp and in good condition.
• TWIST BITS: Available with straight and reduced shanks for wood and light-duty metal drilling. High-speed bits cut faster and last longer on hard materials.
• CARBIDE TIPPED BITS: Used for drilling stone, concrete, plaster, cement and other unusually hard nonmetals. Use continuous heavy feed pressure when employing carbide tip bits.

Drilling Wood

• Be certain workpiece is clamped or anchored firmly. Always apply pressure in a straight line with the drill bit. Maintain enough pressure to keep the drill “biting”.
• When drilling holes in wood, twist bits can be used. Twist bits may overheat unless pulled out frequently to clear chips from flutes.
• Use a “back-up” block of wood for work that is likely to splinter, such as thin materials.
• You will drill a cleaner hole if you ease up on the pressure just before the bit breaks through the wood. Then complete the hole from the back side.

Drilling Metal

There are two rules for drilling hard materials. First, the harder the material, the greater the pressure you need to apply to the tool. Second, the harder the material, the slower the speed. Here are a couple of tips for drilling in metal. Lubricate the tip of the bit occasionally with cutting oil except when drilling soft metals such as aluminum, copper or cast iron. If the hole to be drilled is fairly large, drill a smaller hole first, then enlarge to the required size, it’s often faster in the long run. Maintain enough pressure to assure that the bit does not just spin in the hole. This will dull the bit and greatly shorten its life.

Drilling Masonry
Soft materials such as brick are relatively easy to drill. Concrete, however, will require much more pressure to keep the bit from spinning. Be sure to use carbide tip bits for all masonry work.
Best-performance drilling in masonry is achieved when in drill and hammer mode (GSB18V-800C model only).

Sanding and Polishing

Fine sanding and polishing require “touch”. Select the most efficient speed.
When using polishing bonnets, always be sure the excess string that secures the bonnet is tucked well within the bonnet during operation.

Wire Brushes
Work with brushes requires high speeds.

Brushing Pressure

1. Let the tips of a wire brush do the work. Operate the brush with the lightest pressure so only the tips of the wire come in contact with the work.
2. If heavier pressures are used, the wires will be overstressed, resulting in a wiping action; and if this is continued, the life of the brush will be shortened due to wire fatigue.
3. pply the brush to the work in such a way that as much of the brush face as possible is in full contact with the work. Applying the side or edge of the brush to the work will result in wire breakage and shortened brush life.

Maintenance

To avoid accidents, always disconnect the battery pack from tool before servicing or cleaning.

Service

NO USER-SERVICEABLE PARTS INSIDE. Preventive
maintenance performed by unauthorized personnel may result in the misplacing of internal wires and components which could cause serious hazards. We recommend that all tool service be performed by a Bosch Factory Service Center or Authorized Bosch Service Station.

Batteries

Be alert for battery packs that are nearing their end of life. If you notice decreased tool performance or significantly shorter running time between charges then it is time to replace the battery pack. Failure to do so can cause the tool to operate improperly or damage the charger.

Tool Lubrication

Your Bosch tool has been properly lubricated and is ready for use.

Motors
The motor in your tool has been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend it be examined every six months. Only a genuine Bosch replacement motor specially designed for your tool should be used.

Cleaning

Certain cleaning agents and solvents damage plastic parts. Some of these are gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.
Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through the opening.

Accessory Storage & Maintenance
Store accessories in a dry and temperate environment to avoid corrosion and/or deterioration.

Accessories

Do not use attachments/accessories other than those specified by Bosch. Use of attachments/accessories not specified for use with the tool described in this manual may result in damage to the tool, property damage, and or personal injury.
