Selecting the direction of rotation

Fordrillingandfortighteningscrews,useforward(clockwise)rotation.Forloosening

screwsorremovingajammeddrillbit,usereverse(counterclockwise)rotation.

Note: Thedirectionofrotationisalsodepictedbyanarrowontheforward/reverseslider(3).

Never change the direction of rotation while the motor is running.

• Toselectforwardrotation,pushtheforward/reverseslider(3)totheright(whenviewed

fromthechuckend).

• Toselectreverserotation,pushtheforward/reverseslider(3)totheleft(whenviewed

fromthechuckend).

(1stgear).Alsowhenusinglargerdiameterbitsinwood

turnthetwogearselectorintoposition1.

smallerdiameterbits,turnthetwo-gearselector(4)sothat

thearrowpointstoposition2(2ndgear).

Setting the drilling depth

• Slackenthesidehandle(9)byturningthegrip

counterclockwise.

• Setthedepthstoprod(8)tothedesiredposition.Themaximumdrillingdepthisequal

to the distance between the tip of the drill bit and the front end of the depth stop rod.

• Tightenthesidehandlebyturningthegripclockwise.Makesurethatthesidehandleis

secure and does not slip.

Switching on and off

• Toswitchthetoolon,depressthevariablespeedswitch(1).Thetoolspeeddepends

on how far you depress the switch.

• Forcontinuousoperation,pressthelock-onbutton(2)andreleasethevariablespeed

switch. This option is available only at full speed.

• Toswitchthetooloff,releasethevariablespeedswitch.Toswitchthetooloffwhenin

continuousoperation,depressthevariablespeedswitchoncemoreandreleaseit.

but not so much as to stall the motor or deflect the bit.

•Hold the drill firmly with both hands to control its twisting action. One hand should

be placed on the side handle.

Drilling In Wood

Holesinwoodcanbemadewiththesametwistdrillbitsusedformetalorwithspadebits.These

bits should be sharp and should be pulled out frequently when drilling to clear chips from the flutes.

Drilling In Metal

Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which

shouldbedrilleddry.Thecuttinglubricantsthatworkbestaresulfurizedcuttingoilorlardoil.

Drilling in Masonry (Shift drill into hammer mode)

Use carbide tipped masonry bits. Refer to Drillingsection.Keepevenforceonthedrill
