HART HPDD50 - Adjusting Torque

6 – English
VARIABLE SPEED SWITCH TRIGGER
See Figure 2, page 9.
Thevariablespeedswitchtriggerdelivershigherspeedwith
increasedtriggerpressureandlowerspeedwithdecreased
triggerpressure.
ToturnthedrillON,depresstheswitchtrigger.Toturnit
OFF,releasetheswitchtriggerandallowthechucktocome
toacompletestop.
NOTE: Awhistlingorringingnoisecomingfromtheswitch
duringuseisanormalpartoftheswitchfunction.
NOTE: Runningatlowspeedsunderconstantusagemay
causethedrilltobecomeoverheated.Ifthisoccurs,cool
thedrillbyrunningitwithoutaloadandatfullspeed.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 2, page 9.
Set the direction of rotation selector in the OFF (center
lock)positiontolocktheswitchtriggerandhelpprevent
accidentalstartingwhennotinuse.
Positionthedirectionofrotationselectortotheleftofthe
switchtriggerforforwarddrilling.Positiontheselectorto
therightoftheswitchtriggertoreversethedirection.
NOTE: Thedrillwillnotrununlessthedirectionofrotation
selectorispushedfullytotheleftorright.
NOTICE:
To prevent gear damage, always allow the chuck to
cometoacompletestopbeforechangingthedirection
of rotation.
WARNING:
Battery tools are always in operating condition. Lock
the switch when not in use or carrying at your side,
wheninstallingorremovingthebatterypack,andwhen
installing or removing bits.
INSTALLING/REMOVING BITS
See Figures 3 - 4, page 9.
Thearrowsonthekeylesschuckindicatewhichdirection
torotatethechucksleevetotightenorreleasethedrillbit.
Donotuseawrenchtotightenorloosenthechuckjaws.
To install bits, lock the switch trigger.
Openorclosethechuckjawsuntiltheopeningisslightly
largerthanthebitsizeyouintendtouse.
Raisethefrontofthedrillslightlyandinsertthedrillbit.
OPERATION
WARNING:
Makesuretoinsertthedrillbitstraightintothechuck
jaws.Do notinsert thedrillbit intothe chuckjaws at
anangle,thentighten.Thiscouldcausethedrillbitto
be thrown from the drill, resulting in possible serious
personalinjuryordamagetothechuck.
 Graspandholdthecollarofthechuckwithonehand.
Withyourotherhand,rotate the chuck sleeve to close
andtightenthechuckjaws .
WARNING:
Donotholdthechucksleevewithonehandandusethe
powerofthedrilltotightenthechuckjawsonthedrill
bit.Thechucksleeve couldslipinyourhand,oryour
handcouldslipandcomeincontactwiththerotating
drillbit.Thiscouldcauseanaccidentresultinginserious
personalinjury.
To remove bits, lock the switch trigger and openthe
chuckjaws.
Thebitprovidedwiththedrillcanbeplacedinthestorage
area,locatedonthebaseofthedrill.
ADJUSTING TORQUE

DRILLING/DRIVING SCREWS
See Figure 6, page 9.
 Checkthedirectionofrotationselectorforthecorrect
setting(forwardorreverse).
Securetheworkpieceinaviseorwithclampstokeepit
fromturningasthebitrotates.
Holdthedrillfirmlyandplacethebitatthepointtobe

WARNING:
Donotdriveascrewwherethereislikelytobehidden
wiring behind the surface. Contact with a “live” wire
will make exposed metal parts of the tool “live” and
possiblyshocktheoperator.Ifyoumustdriveascrew
wherehiddenwiremaybepresent,alwaysholdtoolby
