SWITCHING ON AND OFF
Note:
Before engaging the on/off trigger switch,
check to make sure the bit you are using is fitted
correctly and running concentrically.
1. Connect the plug to the power supply.
2. To start the tool, depress the safety lock
button and the trigger button together.
3. Release the trigger and safety lock button to
turn the tool ‘off’.
SETTING THE SPEED
1. The drill has a two speed gearbox.
2. Setting the switch with the arrow on position 1
will give you a variable speed from 0-1100RPM.
or position 2 will give you a faster variable
speed range of 0-3000RPM. Make sure you
CLICK the switch in position properly.
See Fig.1
3. Set the variable speed on the trigger switch to
suit the material being drilled by turning the black
knob clockwise to increase the set speed or anti-
clockwise to decrease the speed.
See Fig.2
CHANGING FROM ROTARY TO IMPACT DRILLING
1. This must only be done when the drill has
stopped rotating as it would cause damage to
the gear-box if tried whilst the drill is running.
2. The slide switch has clearly marked positions
showing a hammer for impact and a drill bit for
rotary a shown in
Fig. 4
CHANGING ROTATIONAL DIRECTION
1. Again this must only be done when the drill has
stopped rotating as it would cause damage to
the gear-box whilst the drill is running. At the
top of the trigger is a lever which selects the
direction of rotation.
See Figs.2 & 3
FITTING A DRILL BIT
1. Rotate the chuck anti-clockwise manually to
open the jaws just wide enough to take the
size of the drill bit being used. Insert the bit
and tighten by rotating the chuck clockwise.
Now check the bit is fitted concentrically.
It now needs tightening using the chuck key in
each of the three holes in turn.
See Fig.5
If you don’t tighten in all three positions the
chuck may come loose allowing the bit to get
stuck in the material. Be sure to remove the
chuck key and return to its holder.
See Fig.6
USING THE SIDE HANDLE
1. The drill has a very powerful motor and it is
therefore recommended to use the side
handle to avoid personal injury if the bit gets
jammed into the material being drilled. This
means drilling with this machine needs to be a
two handed operation.
2. To fit the side handle, unscrew the handle
from its fitting which loosens the clamping
mechanism and enables the handle to be
fitted over the chuck and onto the boss of the
gear box behind the chuck. The handle may be
positioned at any angle around the boss and
can be flipped the opposite way to enable left
hand usage. Tighten the handle again and this
will clamp it in position.
See Fig.7
USING THE DEPTH STOP
1. The depth stop is a bar which shares the
s a m e c l a m p i n g m e c h a n i s m a s t h e s i d e
handle. It has 5mm graduations and can be
used to set the required depth of holes drilled.
To set the depth stop, loosen the handle and
slide the depth stop out to the end of the drill
bit being used. Take note of the reading where
the bar enters the clamp, then take off the
depth required and slide the bar back into the
clamp until it aligns with the new position.
With the depth stop set, tighten the handle to
clamp both the handle and the depth stop in
position. You are now ready to drill holes of
the required/same depth.
