DEPTH GAUGE

Your drilling depth can be pre-set and/or

repeated by using the depth gauge.

Setting depth: After the auxiliary handle is

installed, make sure the accessory has been

fully inserted into the tool holder before setting

the depth gauge (Fig. 5).

To adjust depth, push down on the depth

gauge release lever, slide the depth gauge to

desired depth and release pressure on lever to

lock the depth gauge in place (Fig. 5).

CHUCK KEY & STORAGE AREA

Your tool is equipped with a chuck key that is

conveniently located on the cord protector

where it is always handy and unlikely to get lost

or misplaced (Fig. 1).

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 chuck, insert key into each of the

three key holes in succession and tighten

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

clockwise firmly. The chuck can be released by

using one hole only (Fig. 6).

Operating Tips

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.
