4. USING THE HAMMER DRILL
HDR-7113
Variable Speed Trigger
1. Squeeze the variable speed
trigger to start the drill.
Note:
The more you squeeze
the variable speed trigger,
the higher the speed. The
fastest speed achieved when
the trigger is fully depressed
depends on the speed setting
of the speed selector dial.
2. Release the trigger to stop.
Lock-On Button
The variable speed trigger can be locked in the ‘on’ position if you
will be operating the drill for long periods.
1. Press and hold the variable
speed trigger to start the
drill.
2. Then press and hold the
lock-on button.
3. Release the variable speed trigger then the lock-on button. The
drill will remain on.
4. To stop the lock-on function, squeeze
and release the variable speed trigger.
Hammer Drilling
Before connecting the drill to the power supply, perform a few
simple checks:
1. Press and release the variable speed
trigger to ensure it is not locked on.
2. Check the forward/reverse button for
the correct setting.
3. Secure the material to be drilled in a
vice or clamp to stop it turning whilst
drilling.
4. Plug the hammer drill into the power supply.
5. Hold the drill firmly and
place the bit at the point to
be drilled.
6. Press and hold variable
speed trigger to start the
drill.
7. Move the drill bit into the
workpiece. Apply the lock-on
function if required.
Note:
Do not force the drill or apply side pressure to elongate the
hole. Let the drill do the work.
Helpful Tips
1. When drilling hard, smooth surfaces, use a centre punch to
mark the desired hole location. This measure will prevent the
drill bit from slipping off centre as you start the hole.
2. Alternatively, the variable speed feature allows you to start holes
without centre punching. To accomplish this, operate the drill at
a low speed until you start the hole.
3. 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
drilling action.
4. If the bit jams in the workpiece or if the drill stalls, stop the tool
immediately. Remove the bit from the workpiece and determine
the reason for jamming.
