The purpose of the green 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.

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 oper ation, 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

stop. Prior to driving screws, pilot and clearance holes should be drilled.

FASTENING WITH SCREWS

This procedure shown in (Fig. 7) will enable you to fasten ma terials together with your Cordless Drill/Screwdriver without stripping, splitting or separating the material.

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 “wander ng”i. 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

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.
