CHARGING BATTERY PACK (FAST CHARGER)
Plug charger cord into your standard power outlet, then slide the battery pack into charger (Fig. 7).
The charger’s green indicator will begin to “BLINK”. This indicates that the battery is receiving a fast charge. Fast-charging will automatically stop when the battery pack is fully charged.
When the indicator light stops “BLINKING” (and becomes a steady green light) fast charging is complete.
FIG. 7
When you begin the charging process of the battery pack, a steady green light could also mean the battery pack is too hot or too cold.
The purpose of the light is to indicate that the battery pack is fast-charging. It does not indicate the exact point of full charge. The light will stop blinking in less time if the battery pack was not completely discharged.
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.
CHARGER
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
INDICATOR
LIGHT
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 if necessary.
If you still do not get proper charging,
d. take or send tool, battery pack and charger to your local Skil Service Center.
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. 12) 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.

Apply a slight even pressure when driving screws.
2. Drill same diameter as screw shank.
3. Countersink same diameter as screw head.

Always inspect drill bits for excessive wear.
DRILL BITS
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
DRILLING WOOD
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.

There are two rules for drilling hard materials.
DRILLING METAL
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
Maintenance
more pressure to keep the bit from spinning. Be sure to use carbide tip bits for all masonry work.
WARNING
!
safe operating speed is not exceeded by the nameplate speed of the tool. Do not exceed the recommended wheel diameter.
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.
Before using an accessory, be certain that its maximum
