To insert the battery, align the battery and slide the battery pack 5 into the tool until it locks into position. Do not force.

Warning: If battery release tabs are cracked or otherwise damaged, do not insert into the tool. The battery can fall out during operation.

Mounting and Removing Adapters

• A. Make sure the hex drive 1 is free. Pull out any bit you might have used.
• B. Insert the hex shaft of an adapter into drive 1 and push the adapter until it snaps in place. You may need to rotate the adapter a little.
• C. Lock the adapter in place by turning the lock ring 14 in the direction shown until it clicks (Fig. 3).
  To remove any adapter, turn the lock ring 14 in the direction shown until it clicks. Pull the adapter away from the tool (Fig. 4).

Using Right Angle Adapter

You can rotate the right-angle adapter 13 to any position around the axis of the tool in 9° increments. See Fig. 5.

• A. Make sure the adapter is locked on the tool. Pull the adapter 13 away from the lock ring 14 approximately 3/16” (5mm).
• B. Rotate the adapter 13 to a desired position.
• C. Release the pull and let the adapter return to the locked position.

The right-angle adapter’s interface 13a is identical to the interface of the power tool. You can attach the other 3 adapters to it the same way as the adapters are mounted to the tool (See “Mounting and Removing Adapters”).

Using Offset Adapter

You can rotate the offset adapter 12 to any position around the axis of the tool in 9° increments. See Fig. 6.

• A. Make sure the adapter is locked on the tool. Pull the adapter 12 away from the lock ring 14 by approximately 3/16” (5mm).
• B. Rotate the adapter 12 to the desired position.
• C. Let the adapter snap back towards the lock ring 14.

Inserting and Removing Bits (Main Hex Drive)

You can insert any 1/4” hex bits directly into the main hex drive 1 without using any of the adapters (Fig. 7). The hex drive is magnetized and will prevent the bits from falling out during light drilling or driving.

To remove a bit, simply pull it out.

Inserting and Removing Bits (Hex Chuck)

Bit holder adapter 10 and offset adapter 12 have a chuck that accepts any 1/4” hex bit. To insert an accessory, simply pull the locking sleeve 12a backward, insert the desired accessory into the chuck, and release the locking sleeve to lock the bit (Fig. 8).

To remove an accessory, pull the locking sleeve backward and remove it from the chuck.

Warning: To avoid loss of control, ensure the bit is locked in the chuck by pulling on the bit after it has been inserted.

Inserting and Removing Bits (Drill Chuck)

Move forward/reversing lever 6 to the center “OFF” position. Remove battery pack 5 and rotate the clutch ring 2 to the drill bit symbol . Rotate the chuck sleeve 11a counter-clockwise,vi  ewing from the chuck end, and open the chuck to approximately drill bit diameter. Insert a clean bit up to the drill bit flutes for small bits, or as far as it will go for large bits. Close chuck by rotating the chuck sleeve 11a clockwise and securely tighten by hand (Fig. 9).

Warning: Do not use the power of the drill while grasping the chuck to loosen or tighten the bit. Friction burn, or hand injury,is possible if attempting to grasp the spinning chuck.

Belt Clip and Bit Tip Holder

Bosch GSR12V-300FC comes with the option to use a metal belt clip and a four-piece bit tip holder. Pry off the plastic cover 16 from the back of the drill to install these accessories (Fig. 10).

Belt Clip

Warning: When the tool is attached to the belt, position yourself to avoid entanglement with surrounding objects. Unexpected entanglement could cause the tool to fall, resulting in injury to the operator or bystanders.

The belt clip will allow you to conveniently attach your tool to your belt. This feature will allow you to have both hands free when climbing a ladder or moving to another work area.

The belt clip 17 can be positioned on either side of the tool and secured to the back of the tool with a mounting screw (Fig. 11). Always make sure you securely tighten the mounting screw before use.

To use the clip, turn the tool upside down and attach it to your belt.

4X BIT TIP HOLDER

Warning: Only store short screwdriver bits in the on-tool bit tip holder. Longer bits could interfere with proper tool operation and result in user injury.

The four-piece bit tip holder 18 can be used for convenient tool storage of your most commonly used bits. The bit tip holder can be used on its own or in conjunction with the belt clip accessory 17. If mounting both the belt clip and bit holder accessory, be sure to place the belt clip accessory between the bit tip holder accessory and the tool. Always make sure you securely tighten the mounting screw before use. (Fig. 11).

Operating Instructions

Protection Against Deep Discharging

The lithium-ion battery is protected against deep discharging by the “Electronic Cell Protection (ECP)”. When the battery is discharged, the tool is switched off by means of a protective circuit.

Variable Speed Controlled Trigger Switch

Your tool is equipped with a variable speed trigger switch. The tool can be turned “ON” or “OFF” by squeezing or releasing the trigger. The speed can be adjusted from the minimum to the 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 (Fig. 1).

Brake

When the trigger switch is released, it activates the brake to stop the chuck quickly. This is especially useful, ieepetitive driving and the removal of screws.

Forward/Reversing Lever and Trigger Lock

Warning: After tool use, lock trigger in “OFF” position to help prevent accidental starts and accidental discharge.

Your tool is equipped with a forward/reversing lever and trigger lock 6 located above the trigger (Fig. 12). This lever was designed for changing the rotation of the bit, and for locking the trigger in an “OFF” position.

For forward rotation(with the uck pointed away from you), move the lever to the far left. For reverse rrotationmove the lever to the far right. To activate the trigger lock, move the lever to the center position.

CAUTION: 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.

Gear Shifting

Your tool is equipped with two separate gear ranges: low gear and high gear. 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 switch to a high or low position (Fig. 1).

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

Adjustable Clutch

Your tool features 21 clutch settings. Output torque will increase as the clutch riradius is increasedrom 1 to 20. The drill position will lock up the clutch to permit drilling and driving heavy-duty work (Fig. 1).

Autolock™

Your tool is equipped with an automatic locking system. This feature will lock the bit holder in one position when the trigger switch is released. This will allow you to tighten or loosen a nut or screw by rotating the tool by hand with the switch off. This is convenient when a higher turning torque is needed.

Built-in Work Light

Your tool is also equipped with a light that turns on automatically when the switch is activated, for better visibility when drilling/driving (Fig. 1).

Battery Charge Condition Indicator Lights

Your tool is equipped with charge condition indicator lights (Fig. 1). The indicator lights show the charge condition of the battery for a few seconds when the On/Off trigger is pressed halfway or fully.

Operating Tips

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 the tool and the 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. Before 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. 13 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 a flat-head screw is used, countersink the hole to make the screw flush with the surface. Realign the holes on the two pieces and apply 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,, other unusually hard nonmetals. Use continuous heavy feed pressure when employing carbide tip bits.

Drilling Wood

Be certain the 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 o,, or cast iron. If the hole to be drilled is fairly large, drill a smaller hole first, then enlarge to the required size;e, it’s often faster in the long run. Maintain enough pressure to ensure that the bit does not just spin in the hole. This will dull the bit and greatly shorten its life.

Maintenance

Warning: To avoid accidents, always disconnect the tool and/or charger from the power supply before servicing or cleaning.

Service

Warning: NO USER SERVICEABLE PARTS INSIDE. Preventive maintenance performed by unauthorized personnel may result in the misplacement of internal wires and components,  which could cause e serious hazard.

We recommend that all tool service be performed by a Bosch Factory Service Center or Authorized Bosch Service Station. SERVICEMEN: Disconnect tool and/or charger from power source before servicing.

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

Warning: 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.
