Power Tool Safety Rules
Read and understand all instructions. Failure to follow all instructions
listed below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Keep your work area clean and well lit.
Cluttered benches and dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
Distractions can cause you to lose control.
Double Insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double Insulation eliminates the need for the three wire grounded power cord and grounded power supply system. Before plugging in the tool, be certain the outlet voltage supplied is within the voltage marked on the nameplate. Do not use “AC only” rated tools with a DC power supply.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded. If operating the power tool in damp locations is unavoidable, a Ground Fault Circuit Interrupter must be used to supply the power to your tool. Electrician’s rubber gloves and footwear will further enhance your personal safety.
Don't expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
When operating a power tool outside, use
an outdoor extension cord marked
Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal 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. Keep handles dry, clean and free from oil and grease.
Avoid accidental starting. Be sure switch is “OFF” before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch “ON” invites accidents.
Remove adjusting keys or wrenches before turning the tool “ON”. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.
Use safety equipment. Always wear eye protection. Dust mask,
Tool Use and Care
Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.
Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.
Do not use tool if switch does not turn it “ON” or “OFF”. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control. Any alteration or modification is a misuse and may result in a dangerous condition.
Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools
operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools. Develop a periodic maintenance schedule for your tool.
Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.
Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury. For example: internal wires may be misplaced or pinched, safety guard return springs may be improperly mounted.
When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual.
Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury. Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.
Safety Rules for Drills
Hold tool by insulated gripping surfaces when performing an operation where the cutting tools may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator. 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 use auxiliary handle for maximum control over torque reaction or
High torque 3/8" and larger chuck capacity drills are equipped with auxiliary handles.
Always wear safety goggles or eye protection when using this tool. Use a dust mask or respirator for applications which generate dust.
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.
Never leave the trigger locked "ON". Before plugging the tool in, check that the trigger lock is "OFF". Accidental
Position the cord clear of rotating bit. Do not wrap the cord around your arm or wrist. If you lose control and have the cord wrapped around your arm or wrist it may entrap you and cause injury.
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.
Do not use the switch
Be aware of the location and setting of the switch
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 drill while carrying it at your side. A spinning drill bit could become entangled with clothing and injury may result.
This tool may be used with sanding and polishing disks, grinding wheels, wire wheel and wire cup brushes. These accessories must be rated for at least the speed recommended on the tool warning label. Wheels and other accessories running over rated speed can fly apart and cause injury.
Avoid bouncing and snagging the wheels, discs or brushes especially when working corners, sharp edges, etc. This can cause loss of control and kickback.
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:
•Crystalline silica from bricks and cement and other masonry products, and
•Arsenic and chromium from chemicallytreated 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 those dust masks that are specially designed to filter out microscopic particles.

TRIGGER CONTROLLED VARIABLE SPEED
Your tool is equipped with a variable speed trigger switch. The tool speed can be controlled from minimum to maximum nameplate rated RPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed (Fig. 1).
TO LOCK TRIGGER "ON": squeeze trigger, depress button and release trigger.
TO UNLOCK THE TRIGGER: squeeze trigger and release it without depressing the "LockON" button.
pressed, the trigger can not be released.
REVERSING SWITCH LEVER
The reversing lever is located above the trigger switch and is used to reverse rotation of the bit. To use drill in “Forward” rotation move lever to left side of tool. For “Reverse” rotation move lever to right side of tool.
Do not change direction of
rotation until the tool
comes to a complete stop. Shifting during rotation of the chuck can cause damage to the tool.
VARIABLE SPEED DIAL
This feature enables you to preset the trigger at desired speeds by rotating the dial on the
trigger. Regardless of the pressure applied on trigger, the tool will not operate any faster than maximum preset speed. You can change the preset maximum speed simply by rotating the adjusting dial to a higher or lower speed setting.
GEAR CHANGE SELECTION
Gear selection: The proper gear selection is directly related to the speed and torque required for various jobs. The following should be adhered to when selecting the proper gear:
Speed 1 = low speed with high torque
Speed 2 = high speed with low torque
Changing gears: Change gear position only with the motor at a complete standstill. To change gears rotate the gear selection lever. If you have difficulties changing from one gear to the other, turn the chuck by hand until the gears engage.
The auxiliary handle will provide additional control, support and guidance for the drill. The handle is adjustable to any position around the 360˚ handle collar mount.
Installing side handle: Slide the handle over the handle collar mount. Securely tighten wing knob (A).
Your drilling depth can be
Setting depth: After the auxiliary handle is installed, slide the depth gauge to desired depth and securely tighten wing knob (B).
For small bits, open jaws enough to insert the bit up to the flutes. For large bits, insert the bit as far as it will go. Center the bit as you close the jaws by hand. This positions the bit properly, giving maximum contact between the chuck jaws and the bit shank.
To tighten chuck, insert key into each of the three key holes in succession and tighten clockwise firmly. The chuck can be released by using one hole only (Fig. 2).
CHANGING THE CHUCK
Removing the chuck: First it is necessary to remove the chuck securing screw. This screw is
Always keep the spindle threads, the threads of the chuck and securing screw free of debris. To install a chuck, reverse “removing the chuck” procedure.
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 trigger controlled variable speed feature will eliminate the need for center punches in hard materials. 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 in the drill mode. The technique is to start slowly, increasing the speed as the screw runs down. Set the screw snugly by slowing to a stop. Prior to driving screws, pilot and clearance holes should be drilled.
FASTENING WITH SCREWS
The procedure shown in (Fig. 4) will enable you to fasten materials together with your hammer drill in the drill mode without stripping, splitting or separating the material.
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.
First, clamp the pieces together and drill the first 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 second hole the same diameter as the screw shank in the first or top piece of wood.
FASTENING WITH SCREWS
1.Drill 2/3 diameter and 2/3 of screw length for soft materials, full length for hard materials
2.Drill same diameter as screw shank
3.Countersink same diameter as screw head
Third, if flat head screw is used, countersink the hole to make the screw flush with the surface. Then, simply 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.
Apply a slight even pressure when driving screws
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.
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.
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.
SANDING AND POLISHING
You will find the
When using polishing bonnets, alway be sure the excess string that secures the bonnet is tucked well within the bonnet during operation.
Work with brushes requires high speeds. Use of the
1.Remember, 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.Apply 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.
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.
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.
! WARNING 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 wheel diameter.
CORRECT: Wire tips doing the work.
INCORRECT: Excessive pressure can cause wire breakage.
RUNNING 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.
Preventive maintenance performed by unauthorized personnel may result in misplacing
of internal wires and 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.
Your Bosch tool has been properly lubricated and is ready to use. It is recommended that tools with gears be regreased with a special gear lubricant at every brush change.
The brushes and commutator in your tool have been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend every two to six months the brushes be examined. Only genuine Bosch replacement brushes specially designed for your tool should be used.
should be replaced at Bosch Factory Service Center or Authorized Bosch Service Station. Bearings which become noisy (due to heavy load or very abrasive material cutting) should be replaced at once to avoid overheating or motor failure.
To avoid accidents always disconnect the tool from the power supply before cleaning or
performing any maintenance. The tool may be cleaned most effectively with compressed dry air. Always wear safety goggles when cleaning tools with compressed air.
Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through openings.
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.
If an extension cord is necessary, a cord with adequate size conductors that is capable
of carrying the current necessary for your tool must be used. This will prevent excessive voltage drop, loss of power or overheating. Grounded tools must use 3- wire extension cords that have
NOTE: The smaller the gauge number, the heavier the cord.
