		General Safety Rules
		For All Battery Operated Tools
		Read and understand all instructions. Failure to follow all instructions
	! WARNING
		listed below, may result in electric shock, fire and/or serious personal
	injury.
		SAVE THESE INSTRUCTIONS

Work Area

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.

Keep by-standers, children, and visitors away while operating a power tool.

Distractions can cause you to lose control.

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 enable better control of the tool in unexpected situations.

Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

Electrical Safety

A battery operated tool with integral batteries or a separate battery pack must be recharged only with the specified charger for the battery. A charger that may be suitable for one type of battery may create a risk of fire when used with another battery.

Use battery operated tool only with specifically designated battery pack. Use of any other batteries may create a risk of fire.

Personal Safety

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.

Avoid accidental starting. Be sure switch is in the locked or off position before inserting battery pack. Carrying tools with your finger on the switch or inserting the battery pack into a tool with the switch on invites accidents.

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. A tool that cannot be controlled with the switch is dangerous and must be repaired.

Disconnect battery pack from tool or place the switch in the locked or off position 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.

When battery pack is not in use, keep it away from other metal objects like: paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another.

Shorting the battery terminals together may cause sparks, burns, or a fire.

Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edge are less likely to bind and are easier to control.

Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool's operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

Use only accessories that are recommended by the manufacturer for your model. Accessories that may be

suitable for one tool may create a risk of injury when used on another tool.

Service

Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel may result in a risk of injury.

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 shock or injury.

Safety Rules for Cordless Drills/Drivers

Hold tool by insulated gripping surfaces when performing an operation where the cutting tools may contact hidden wiring.

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 hold the tool with both hands. If the bit jams two hands will give you maximum control over torque reaction or kickback.

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.

Disconnect battery pack from tool or place the switch in the locked or off position 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

BM 1619X01517 03-06 3/30/06 3:20 PM Page 4

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.

Use a stud sensor to determine where studs may be located. The stud sensor may also be able to detect other objects hidden in a wall such as conduit, gas or water pipes. If you are uncertain about the work area call the local utility company for assistance before beginning

the project. Striking or cutting into a gas line will result in explosion. Water entering an electrical device may cause electrocution. Cutting into live electrical wiring may cause a shock hazard.

! WARNING 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 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.

Battery/Charger

Before using battery charger, read all instructions and cautionary markings on

(1) battery charger, (2) battery pack, and

(3) product using battery.

Use only the charger which accompanied your product or direct replacement as listed in the catalog or this manual. Do not substitute any other charger. Use only Skil approved chargers with your product. See Functional Description and Specifications.

Do not disassemble charger or operate the charger if it has received a sharp blow, been dropped or otherwise damaged in any way. Replace damaged cord or plugs immediately. Incorrect reassembly or damage may result in electric shock or fire.

Do not recharge battery in damp or wet environment. Do not expose charger to rain or snow. If battery case is cracked or otherwise damaged, do not insert into charger. Battery short or fire may result.

Charge only Skil approved rechargeable batteries. See Functional Description and Specifications. Other types of batteries may burst causing personal injury and damage.

Charge battery pack in temperatures above +40 degrees F (4 degrees C) and below +105 degrees F (41 degrees C). Store tool and battery pack in locations where temperatures will not exceed 120 degrees F (49 degrees C). This is important to prevent serious damage to the battery cells.

Battery leakage may occur under extreme usage or temperature conditions. Avoid contact with skin and eyes. The battery liquid is caustic and could cause chemical burns to tissues. If liquid comes in contact with skin, wash quickly with soap and water, then with lemon juice or vinegar. If the liquid contacts your eyes, flush them with water for a minimum of 10 minutes and seek medical attention.

Place charger on flat non-flammable surfaces and away from flammable materials when re-charging battery pack.

The charger and battery pack heat during charging. Carpeting and other heat insulating surfaces block proper air circulation which may cause overheating of the charger and

battery pack. If smoke or melting of the case are observed unplug the charger immediately and do not use the battery pack or charger.

Use of an attachment not recommended or sold by Skil may result in a risk of fire, electric shock or injury to persons.

Battery Care

! WARNING When batteries are not in tool or charger, keep them

away from metal objects. For example, to protect terminals from shorting DO NOT place batteries in a tool box or pocket with nails, screws, keys, etc. Fire or injury may result.

! WARNING To prevent fire or injury when batteries are not in

tool or charger, always place protective cap onto end of battery pack. Protective cap, guards against terminal shorting.

DO NOT PUT BATTERIES INTO FIRE OR EXPOSE TO HIGH HEAT. They may explode.

Battery Disposal

! WARNING Do not attempt to disassemble the battery or

remove any component projecting from the battery terminals. Fire or injury may result. Prior to disposal, protect exposed terminals with heavy insulating tape to prevent shorting.

NICKEL-CADMIUM BATTERIES

If equipped with a nickel-cadmium battery, the battery must be collected, recycled or disposed of in an environmentally sound manner.

“The EPA certified RBRC Battery Recycling Seal on the nickel-cadmium (Ni-Cd)

battery indicates Robert

Operating Instructions

VARIABLE SPEED CONTROLLED

TRIGGER SWITCH

Your tool is equipped with a variable speed trigger switch. The tool speed can be controlled 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 speed. This accurate speed control enables you to drill without center punching. It also permits you to use as a power screwdriver. Bits are available for driving screws as well as running bolts and nuts.

FORWARD/REVERSING LEVER &

TRIGGER LOCK

Your tool is equipped with a forward/ reversing lever and trigger lock located above the trigger (Fig. 1). This lever was designed for changing rotation of the chuck, and for locking the trigger in an “OFF” position to help prevent accidental starts and accidental battery discharge. 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 trigger lock move lever to the center off position.

Do not change direction of ! CAUTION rotation until the tool

comes to a complete stop. Shifting during rotation of the chuck can cause damage to the tool.

ADJUSTABLE CLUTCH

Your tool features 6 clutch settings. Output torque will increase as the clutch ring, is rotated from 1 to 5. The drill “ ” position will lock up the clutch to permit drilling and driving heavyduty work, and also enables bits to be changed quickly and easily in the keyless chuck.

BRAKE

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

INSERTING BIT

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, hold the chuck collar firmly with one hand and securely tighten the chuck sleeve with the other hand (Fig. 2).

! WARNING Do not use the power of the drill while grasping

chuck to loosen or tighten bit. Friction burn or hand injury is possible if attempting to grasp the spinning chuck.

REMOVING CHUCK

Rotate the clutch ring to the drill bit symbol “ ”. Open the chuck all the way, remove left-hand thread screw inside chuck by turning it clockwise. Insert the short arm of a 3/8" hex key wrench and close jaws on flats of wrench. Strike long arm of wrench sharply counterclockwise, remove wrench and unthread chuck from spindle (Fig. 2).

CHARGING BATTERY PACK (3 HOUR CHARGER)

Plug charger cord into your standard power outlet. Before inserting battery pack, remove protective cap, then insert battery pack into charger (Fig. 6).

The charger’s green light (Fig. 7), will turn “ON”. The green light remains ‘‘ON’’ as long as charger is plugged in, and does not shut off.

After normal usage, the battery pack requires approximately 3 hours or less charging time to become fully charged. If the battery pack is

run-down completely, it may require up to 5 hours charging time to become fully charged.

When the battery pack is fully charged, unplug the charger (unless you're charging another battery pack) and slip the battery pack back into the tool handle.

To prevent fire or injury when batteries are not in tool or charger, always place protective cap onto end of battery pack.

BATTERY PACK

IMPORTANT CHARGING NOTES

1.The battery pack accepts only about 80% of its maximum capacity with its first few charge cycles. However, after the first few charge cycles, the battery will charge to full capacity.

2.The charger was designed to fast charge the battery only when the battery temperature is between 40˚F (4˚C) and 105˚F (41˚C).

3.A substantial drop in operating time per charge may mean that the battery pack is nearing the end of its life and should be replaced.

4.If you anticipate long periods (i.e. a month or more) of non-use of your tool, it is best to run your tool down until it is fully discharged before storing your battery pack. After a long period of storage, the capacity at first recharge will be lower. Normal capacity will be restored in two or three charge/discharge cycles.

Remember to unplug charger during storage period.

5.If battery does not charge properly:

a.Check for voltage at outlet by plugging in some other electrical device.

b.Check to see if outlet is connected to a light switch which turns power “off” when lights are turned off.

c.Check battery pack terminals for dirt. Clean with cotton swab and alcohol if necessary.

d.If you still do not get proper charging, take or send tool, battery pack and charger to your local Skil Service Center. See “Tools, Electric” in the Yellow Pages for names and addresses.

Note: Use of charger’s or battery packs not sold by Skil will void the warranty.

Operating Tips

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

This procedure shown in (Fig. 8) will enable you to fasten materials together with your Cordless Drill/Screwdriver without stripping, splitting or separating the material.

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.

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.

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.

FASTENING

WITH SCREWS

1.Drill 2/3 diameter and 2/3 of screw length for soft materials, full length for hard materials.

FIG. 8

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.

-11-

BM 1619X01517 03-06 3/30/06 3:20 PM Page 12

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.

! 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.

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. 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.

CORRECT: Wire tips doing the work.

15

INCORRECT: Excessive pressure can cause wire breakage.

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.

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.
