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.
Drilling in wood or metal
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 workpieces in a
vise or similar hold-down device.
NOTICE: Never use “rotation with hammering”
when the drill chuck is installed on the tool.The
drill chuck may be damaged.
Also,thedrillchuckwillcomeoffwhenreversingthetool.
NOTICE: 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.
Set the action mode changing knob to the symbol.
Attachthechuckadaptertoakeylessdrillchuckto
which1/2"-20sizescrewcanbeinstalled,andthen
installthemtothetool.Wheninstallingit,refertothe
section “Installing or removing drill bit”.
