WARNING!
Always wear safety goggles or safety
glasses with side shields during power
tool operation or when blowing dust.
If the operation is dusty, also wear a
dust mask.
1. Check the direction-of-rotation selector for the correct setting (forward or reverse).
2. Use a vise or clamps to secure the material to be drilled to keep it from turning as the drill bit rotates.
3. hold the cordless drill/driver firmly, and place the bit at the point to be drilled.
4. depress the trigger switch to start the cordless drill/driver.
5. Move the drill bit into the workpiece, applying only enough pressure to keep the bit cutting.
6. do not force the cordless drill/driver or apply sideways pressure to elongate a hole. Allow the tool to do
the work.
7. When drilling hard, smooth surfaces, use a centre punch to mark the desired location of the hole. This will
prevent the drill bit from slipping off-centre when the hole is started.
8. When drilling metal, use light oil on the drill bit to prevent it from overheating. The oil will prolong the life
of the bit and will increase the drilling efficiency.
9. If the bit jams in the workpiece or if the drill/driver stalls, stop the tool immediately. Reverse the direction
of rotation and gently squeeze the trigger to remove the bit from the workpiece. Investigate and correct
the cause of jamming before resuming work.
WARNING!
Be prepared for binding when the bit breaks through the workpiece, because the drill/driver
has a tendency to grab and kick opposite to the direction of rotation, which could cause a loss
of control. If the operator is not prepared, this loss of control could result in serious injury.
drilling mode operation
For driLLinG in Wood, use tWist Bits, sPAde Bits, PoWer AuGer Bits or hoLe sAWs.
1. When drilling “through” holes, place a block of wood behind the workpiece to prevent ragged or
splintered edges on the back side of the hole.
2. Select the desired speed to match the planned operation.
3. Begin drilling at a very low speed to prevent the bit from slipping off of the starting point, and then
increase the speed as the drill bit bites into the material.
4. If the drill/driver stalls, it is usually because it is being overloaded. Release the trigger switch
immediately, remove the drill bit from the work, and determine the cause of stalling.
5. Keep the motor running when pulling the bit back out of the drilled hole. This will prevent jamming.
For driLLinG in metAL, use hiGh sPeed steeL tWist driLL Bits.
1. Use light oil on the drill bit to keep it from overheating; the oil will prolong the life of the bit and increase
the drilling action.
2. When drilling a large hole, first use a smaller bit to drill a small pilot hole to prevent the larger bit from
slipping.
3. Select the desired speed to match the planned operation.
4. Begin drilling at a very low speed to prevent the bit from slipping off the starting point. Maintain a speed
and pressure which allows cutting without overheating the bit.
5. If the drill stalls, it is usually because it is being overloaded. Release the trigger switch immediately,
remove the drill bit from the work, and determine the cause of stalling.
6. Keep the motor running when pulling the bit back out of the drilled hole. This will prevent jamming.
screwdriver operation
1. Select the desired speed/torque range to match the planned operation.
2. Attach the desired fastener accessory into the chuck.
3. Make a few practice runs in a scrap piece before working.
