Screwdriving operation
CAUTION: Adjust the adjusting ring to the
proper torque level for your work.
CAUTION: Make sure that the driver bit is
inserted straight in the screw head, or the screw
and/or driver bit may be damaged.
First, turn the action mode changing ring so that the
arrowonthetoolbodypointstothe marking.
Placethepointofthedriverbitinthescrewheadand
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the switch trigger
as soon as the clutch cuts in.
NOTE: When driving wood screw, pre-drill a pilot hole
2/3thediameterofthescrew.Itmakesdrivingeasier
and prevents splitting of the workpiece.
Hammer drilling operation
CAUTION: There is a tremendous and sud-
den twisting force exerted on the tool/drill bit
at the time of hole breakthrough, when the hole
becomes clogged with chips and particles, or
when striking reinforcing rods embedded in the
concrete.
First, turn the action mode changing ring so that the
arrowonthetoolbodypointstothe marking.The
adjustingringcanbealignedinanytorquelevelsfor
this operation.
Besuretouseatungsten-carbidetippeddrillbit.
Positionthedrillbitatthedesiredlocationforthehole,
then pull the switch trigger. Do not force the tool. Light
pressuregivesbestresults.Keepthetoolinposition
and prevent it from slipping away from the hole.
Donotapplymorepressurewhentheholebecomes
clogged with chips or particles. Instead, run the tool at
anidle,thenremovethedrillbitpartiallyfromthehole.
Byrepeatingthisseveraltimes,theholewillbecleaned
outandnormaldrillingmayberesumed.
Blow-out bulb
Optional accessory
►Fig.14: 1.Blow-outbulb
Afterdrillingthehole,usetheblow-outbulbtocleanthe
dust out of the hole.
Drilling operation
First, turn the action mode changing ring so that the
arrow points to the marking.Thenproceedas
follows.
Drilling in wood
Whendrillinginwood,thebestresultsareobtained
withwooddrillsequippedwithaguidescrew.Theguide
screwmakesdrillingeasierbypullingthedrillbitinto
the workpiece.
Drilling in metal
Topreventthedrillbitfromslippingwhenstartinga
hole, make an indentation with a center-punch and
hammeratthepointtobedrilled.Placethepointofthe
drillbitintheindentationandstartdrilling.
Useacuttinglubricantwhendrillingmetals.Theexcep-
tionsareironandbrasswhichshouldbedrilleddry.
