DRILLING

Screwdriving (Fig. K)

1. Select the desired speed/torque range using the

gear shifter to match the speed and torque to the

plannedoperation.

2. Turn the torque adjustment collar

3

to the

desiredposition.

nOTE: Use the lowest torque setting required to

seat the fastener at the desired depth. The lower the

number, the lower the torqueoutput.

3. Insert the desired fastener accessory into the chuck as

you would any drillbit.

4. Make some practice runs in scrap or on unseen areas of

the workpiece to determine the proper position of the

torque adjustmentcollar.

5. Always start with lower torque settings, then advance

to higher torque settings to avoid damage to the

workpiece orfastener.

Hammerdrilling (Fig. L)

1. Select the desired speed/torque range using the gear

shifter to match the speed and torque to the planned

operation. Turn the collar

(

3

)

to the hammerdrillsymbol.

iMPORTAnT: Use carbide-tipped or masonry bits rated

for percussion drillingonly.

2. Drill with just enough force on the hammer to keep

it from bouncing excessively or "rising" off the bit.

Too much force will cause slower drilling speeds,

overheating, and a lower drillingrate.

3. Drill straight, keeping the bit at a right angle to the work.

Do not exert side pressure on the bit when drillling as

this will cause clogging of the bit flutes and a slower

drillingspeed.

4. When drilling deep holes, if the hammer speed starts to

drop off, pull the bit partially out of the hole with tool

still running to help clear debris from thehole.

nOTE: A smooth, even flow of dust from the hole indicates

proper drilling rate
