OPERATION
CAUTION: Always insert the battery cartridge
all the way until it locks in place. If you can see
theredpartontheuppersideofthebutton,itisnot
locked completely. Insert it fully until the red part can-
notbeseen.Ifnot,itmayaccidentallyfalloutofthe
tool,causinginjurytoyouorsomeonearoundyou.
CAUTION: When the speed comes down
extremely, reduce the load or stop the tool to
avoid the tool damage.
Holdthetoolrmlywithonehandonthegripandthe
otherhandonthebottomofthebatterycartridgeto
control the twisting action.

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

Drilling in metal
Topreventthedrillbitfromslippingwhenstartinga

tionsareironandbrasswhichshouldbedrilleddry.
CAUTION: Pressing excessively on the tool
will not speed up the drilling. In fact, this excessive
pressure will only serve to damage the tip of your drill
bit,decreasethetoolperformanceandshortenthe
service life of the tool.
CAUTION: Hold the tool rmly and exert care
when the drill bit begins to break through the
workpiece.Thereisatremendousforceexertedon
thetool/drillbitatthetimeofholebreakthrough.
CAUTION: A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it rmly.
CAUTION: Always secure small workpieces
in a vise or similar hold-down device.
CAUTION: If the tool is operated continuously
until the battery cartridge has discharged, allow
the tool to rest for 15 minutes before proceeding
with a fresh battery.
