OPERATION
CAUTION: Always use the side grip (auxiliary
handle) and rmly hold the tool by both side grip
and switch handle during operations.
CAUTION: Always make sure that the work-
piece is secured before operation.
CAUTION: Do not pull the tool out forcibly
even the bit gets stuck. Loss of control may
cause injury.
NOTE:Ifthebatterycartridgeisinlowtemperature,
thetool’scapabilitymaynotbefullyobtained.Inthis
case,warmupthebatterycartridgebyusingthe
toolwithnoloadforawhiletofullyobtainthetool’s
capability.
Hammer drilling operation
CAUTION: There is tremendous and sudden
twisting force exerted on the tool/drill bit at the time of
hole break-through, when the hole becomes clogged
with chips and particles, or when striking reinforcing
rods embedded in the concrete. Always use the side
grip (auxiliary handle) and rmly hold the tool by
both side grip and switch handle during opera-
tions.Failuretodosomayresultinthelossofcontrol
ofthetoolandpotentiallysevereinjury.
Set the action mode changing knob to the symbol.
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.
NOTE:Eccentricityinthedrillbitrotationmayoccur
while operating the tool with no load. The tool auto-
maticallycentersitselfduringoperation.Thisdoesnot
affect the drilling precision.
Chipping/Scaling/Demolition
Set the action mode changing knob to the symbol.
Holdthetoolrmlywithbothhands.Turnthetoolon
andapplyslightpressureonthetoolsothatthetoolwill
not bounce around, uncontrolled.
Pressingveryhardonthetoolwillnotincreasethe
efciency.
