Selecting the required function
It is possible to use the rotary
hammer drill in four different
modes of operation:
1. Rotation only
Non hammer action, non pneumatic
For drilling into metal and wood
products, can be used with the
13mm keyed chuck (Fig. P).
2. Rotary hammer action
Pneumatic
For drilling into brick
and masonry products (Fig. Q).
CAN NOT be used with the
13mm keyed chuck.
Use SDS drill bits only.
3. Chisel rotation mode
Allows the operator to rotate a flat
chisel to the most suitable angle
for the task (Fig. R).
CAN NOT be used with
the 13mm keyed chuck.
4. Non rotating, pneumatic
hammer action
For light demolition work or
chiselling such as lifting tiles (Fig. S).
CAN NOT used with the 13mm
keyed chuck.
1. To select the required mode of
operation, press the selector
button (7) and set selector knob
(6) to the appropriate position.
2. Release the button (7).
Hints for use
Note. When drilling into masonry, the drilling rate is fast
and burnout of the tip will occur if the drill bit is not
constantly cleared.
• Use only correctly sharpened
drill bits, which are suitable for
the material being drilled.
• To drill hard materials, firm
pressure is required on
the power tool. However,
excessive pressure does not
improve performance and
places unnecessary pressure
on the tool and its bit.
• When driving screws, always use a pilot hole and set the
speed dial to low. Press firmly on the screw head and pull
the trigger gradually increasing the speed. It is always
wiser to test the screw driving on a scrap piece of the
same material you are using.
• Larger diameter holes in hard wood, steel and concrete
have to be drilled at slower speeds. However, the motor
must not be struggling with the operation. If the motor is
struggling DO NOT continue working, pull the drill clear of
the work piece and run it on fast speed for a minute or so
allowing the motor time to cool down before you attempt
a little more of the work. If the job is too hard for the drill,
do not continue, otherwise permanent damage to the
motor will occur.
• Wire brushing or sanding should be carried out on the
highest speed.
• Concrete drilling should be carried out on the highest
speed.
DO NOT overload motor when drilling concrete.
DO NOT use too much pressure as the hammer action
relies on the drill bit being able to move back and forward
in the hole being drilled. Always clear the flutes of the drill
bit by removing it from the hole regularly.
