NOT AVAILABLE ON ALL MODELS
VARIABLE SPEED CONTROLLED
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.
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.
FORWARD/REVERSE INDICATOR LIGHTS
Your tool is equipped with lights which indicates the rotation of the chuck.
For forward rotation, (with chuck pointed away from you) move the forward/reversing lever to the far left and the green indicator will light up when the trigger is activated.
For reverse rotation move the forward /reversing lever to the far right and the red indicator light will light up when the trigger is activated.
To activate trigger lock move the forward/ reversing lever to the center off position.

Your tool features 16 clutch settings. Output torque will increase as the clutch ring, is rotated from 1 to 15. The drill “ ” position will lock up the clutch to permit drilling and driving for heavyduty work.
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.

IMPORTANT CHARGING NOTES
1. The battery pack accepts only about 80% of i
ts 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
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.
in two or three charge/discharge cycles. Remember to unplug charger during storage period.
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.
FASTENING WITH SCREWS
1. Drill 2/3 diameter and
2/3 of screw length for soft materials, full length for hard materials.
Screw
Apply a slight even pressure when driving screws.

2. Drill same
diameter as screw shank.
3. Countersink
same diameter as screw head.
Adjustable
Screw
Drill
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
-12-
SM 1619X02853 11-07 11/28/07 9:14 AM Page 13
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.
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.
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.
WARNING
!
safe operating speed is not exceeded by the nameplate speed of the tool. Do not exceed the recommended wheel diameter.
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.
Work with brushes requires high speeds.
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.
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.
Before using an accessory, be certain that its maximum
