Safety Instructions for Charger and Batteries (Cont’d.)
BATTERY DISPOSAL
Do not attempt to
! WARNING 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 BATTERY
•If equipped with a nickel-cadmium battery, the battery must be recycled or disposed of in an environmentally
sound manner. Check with your county’s Public Works Department for information on recycling batteries.
Charging Battery
REMOVING BATTERY PACK
Before charging, remove battery pack from Drill/Driver by depressing the battery release button and pulling the battery pack out of tool.
GENERAL INSTRUCTIONS
With normal use, as battery pack approaches the discharged state, you will notice a sharp drop in tool performance. When the tool is unable to perform the task at hand, it is time to recharge the battery pack. Recharging the battery pack before this condition is reached will reduce
the total work life of the pack. Discharging the pack beyond this point can damage the pack.
NOTE: Battery temperature will increase during and shortly after use. Batteries may not accept a full charge if they are charged immediately after use. Do not charge battery pack if it feels hot to the touch. Wait for it to cool.
INITIAL CHARGING
Before using the cordless Drill/Driver for the first time, charge the battery fully. Depending on room temperature and line voltage, the battery should be fully charged in six (6) to ten (10) hours.
CHARGING
Connect the current carrying prongs on the power cord to a 230V / 240V AC 50Hz wall outlet. Connect the other end of the power cord to the battery pack. If the charger is equipped with an LED, a red light will light up as long as the battery pack is connected to the charger and the charger is plugged in.
With normal use, the battery pack will be fully charged after about three (3) to six (6) hours. Disconnect charger from power source when not in use.
IMPORTANT: THE BATTERY PACK SHOULD NOT BE LEFT ON THE CHARGER FOR MORE THAN FORTY-EIGHT (48) HOURS.
Operation
VARIABLE-SPEED TRIGGER SWITCH (some models)
If your Drill/Driver is equipped with a variable-speed trigger switch, the pressure you apply to the trigger controls the tool speed. Apply more pressure to increase the speed and release pressure to decrease speed. This accurate speed control allows you to drill without center-punching and to use the Drill/Driver as a power screwdriver. Bits are available for driving screws as well as running bolts and nuts.
FORWARD/REVERSE BUTTON
For forward rotation, firmly press in on the lever marked FWD. For reverse rotation, firmly press in on the lever marked REV.
TRIGGER LOCK
To activate trigger lock, move the forward/reverse lever so it is centered in the handle.
GEAR SHIFTING (DG151905CD only)
The DG151905CD Drill/Driver is equipped with two separate gear ranges, low and high. 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 switch to the high or low position. Actuate trigger slightly if the gear shift does not fully engage.
Note: If Drill/Driver is running, but the chuck will not turn, check to make sure the gear shifting switch is pushed fully into desired setting.
ADJUSTABLE CLUTCH
This Drill/Driver features 16 clutch settings. Output torque will increase as the clutch ring is rotated from 1 to 16.
1 to 2 for driving small screws.
3 to 4 for driving screws into soft materials or plastics.
5 to 7 for driving screws into softwoods.
8 to 10 for medium woods.
11 to 14 for driving screws into medium / hard woods.
15 to 16 for driving screws into metal.
The “drill” position locks up the clutch to permit heavy-duty drilling and driving work. It also allows bits to be changed quickly and easily in the keyless chuck.
INSERTING BITS
Move Forward/Reverse Button to the center “Off” position. Remove battery pack (See “Charging Battery” section) and rotate the clutch ring to the drill bit symbol. Rotate the chuck sleeve counterclockwise (viewing from chuck end), and open chuck to approximate
Operation (Cont’d.)
Do not use the
! CAUTION power of the drill to loosen or tighten bit while holding chuck. The spinning chuck will cause friction burn or hand injury.
REMOVING CHUCK
Remove battery pack. Rotate clutch ring to drill bit symbol and open chuck all the way. Turn left-hand-threaded screw inside chuck clockwise, and remove it . 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.
INSTALLING CHUCK
To install chuck, reverse “Removing Chuck” procedure. Always keep the spindle threads, chuck threads, and securing screw free of debris.
GENERAL DRILLING
The front end of
! WARNING the Drill/Driver may be made “live” if the tool drills into live wiring in the wall. TO PREVENT ACCIDENTAL ELECTRICAL SHOCK, HOLD DRILL/DRIVER ONLY BY THE SOFT GRIP HANDLE.
! WARNING glassesSafety must be worn during operation.
1.Set torque adjusting collar for drilling operation and set speed selector to appropriate speed.
2.Be sure drill bit is securely gripped in chuck.
3.Set FORWARD/REVERSE BUTTON for clockwise rotation.
Make sure work is ! CAUTION held securely in a
vice or clamped in place prior to starting drilling operation. Loose work may spin and cause bodily injury.
4.Locate exact center for hole to be drilled and using a center punch, make a small dent in work.
5.Place tip of drill bit in dent made by center punch, hold drill square with work, and start the motor.
Applying too
! CAUTION much pressure may cause the bit to overheat or break, resulting in bodily injury or damaged drill bits.
Apply steady, even pressure to keep drill bit cutting. Too little pressure will keep the bit from cutting. Eventually, the excessive friction created by sliding over the surface will dull the cutting edges.
| | Always be alert |
| ! CAUTION |
| and brace yourself |
against the twisting action of the drill.
6.If drill stalls or becomes jammed in the hole, release trigger immediately, remove drill bit from work and determine cause of stalling or jamming.
Do not squeeze
NOTICE trigger on and off in an attempt to free a stalled or jammed drill. This will damage the motor.
The direction of rotation may be reversed to help free a jammed bit. Be sure direction of rotation is RESET before attempting to continue drilling.
7.Reduce the pressure on the drill just before the bit cuts through the work to avoid splintering wood or stalling in metal.
8.When bit has completely penetrated work and is spinning freely, withdraw it from the work while the motor is still running, then turn off drill.
DRILLING WOOD
In addition to the instructions listed under GENERAL DRlLLlNG, the following also apply:
1.When using a twist drill in wood, frequently withdraw it from the hole to clear away chips which build up in the flutes. This helps prevent overheating and burning work.
2.If a backing block is used to keep back of work from splintering,
clamp it securely in place. If a backing block is not used with spade bits or hole saws, ease up pressure as soon as bit point breaks through work, and complete the hole from the opposite side.
DRILLING METAL
In addition to the instructions listed under GENERAL DRlLLlNG, the following also apply:
1.Use only good quality sharp high speed steel twist bits when drilling metal.
2.Start drilling with slow speed and gradually increase speed as drill cuts. The harder the material, the slower the speed required. The softer the material, the faster the speed.
3.When drilling a large hole, it is easier to first drill a smaller hole and then enlarge it to the required size.
4.The use of a lubricant, such as oil, on the drill point helps keep the bit cool, increases drilling action and prolongs drill bit life.
5.If possible, punch the drilling position first to prevent drill bit run away.
DRIVING WOOD SCREWS
1.Drill pilot and shank clearance holes. See chart titled “Suggested Hole Sizes for Wood Screws.”
2.Install proper screwdriver bit.
3.Set torque adjusting collar for desired torque and set speed selector to “1,” the low-speed setting.
4.Set drill for correct rotation.
5.Start screw straight in hole with fingers.
6.Place bit on screw, start drill and exert pressure to drive screw.
7.As soon as screw has seated, release trigger, and lift screwdriver from screw.
8.A lubricant, such as soap or wax, may be used on screw threads for ease of driving. This is particularly important in hard wood.
