DRIllING
1. Secure the material to be drilled in a vise or with clamps to keep it from turning as the drill bit
rotates.
2. Unplug the hammer drill from the power source.
3. Install the auxiliary handle and the correct bit.
4. Connect the hammer drill to the power source
5. Verify that the direction-of-rotation selector is at the correct setting (forward).
6. Hold the hammer drill firmly with one hand on the primary handle and the other hand on the
auxiliary handle
7. Place the bit at the point to be drilled.
8. Press the trigger switch to start the hammer drill.
9. Move the drill bit into the workpiece, applying only enough pressure to keep the bit cutting. Do not
force the hammer drill or apply side pressure to elongate a hole. Allow the tool to do the work.
10. 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 as the hole is started.
11. When drilling metals, 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.
12. If the bit jams in the workpiece or if the drill stalls, stop the tool immediately. Reverse the direction
of rotation and gently squeeze the trigger switch to remove the bit from the workpiece. Investigate
and correct the cause of jamming before you resume work.
Installing bits
(fig 6)
1. Unplug the hammer drill from the power source.
2. Open the chuck jaws by turning the sleeve in
a counterclockwise direction until the opening
is slightly larger than the bit you intend to use,
and raise the front of the drill slightly to
keep
the bit from falling out of the chuck jaws.
3. Insert the drill bit into the chuck.
4. Tighten the sleeve by hand.
5. Place the chuck key in one of the three chuck key holes and tighten in clockwise direction.
Repeat
with the remaining two chuck key holes.
WARNING!
It is important to tighten the chuck with all three key holes to prevent slippage.
6. Remove the chuck key.
WARNING!
Insert the drill bit straight into the chuck jaws. Inserting the drill bit into the chuck jaws at an
angle and then tightening the chuck and using the drill could cause the drill bit to be thrown
from the hammer drill, resulting in possible serious personal injury or damage to the chuck.
Removing bits (fig 7)
WARNING!
Use protective gloves when removing
the bit from the tool, or allow the bit
to cool down first. The bit may be hot
after prolonged use.
1. Unplug the hammer drill from the power source.
2. Place the chuck key in one of the three chuck
key holes and loosen the chuck by turning in a
counterclockwise direction.
3. Remove the chuck key.
4. Loosen the sleeve by hand.
5. Remove the drill bit.
