6. FORWARD AND REVERSE ROTATION
CONTROL (SEE FIG. C)
Forward rotation: Push the forward and reverse
rotation control to the left "
Reverse rotation: Push the forward and reverse
rotation control to the right "
drill bits.
WARNING: Never change the direction of
rotation while the tool is rotating, wait
until it has stopped.
7. AUXILIARY FUNCTION ON TILE
1) Press ON/OFF switch to see the light is on or off.
Light on indicates the auxiliary function is on, and light
off indicate the auxiliary function is turn off.
2) When operating on the tile, press the auxiliary
function button on tile (10) first, the green light on
means that auxiliary function is on, then half-press
switch, begin pulse auxiliary operation. Until the glaze
of tile is broken, press the ON/OFF switch to the
bottom and begin the drilling .
3) When operating on things rather than tile, keep the
auxiliary function button closed, to insure the high
efficiency when drilling.
Note:
a) Auxiliary function on tile avoids the unexpected
split of tile. This auxiliary function takes the place of
previous pre-drilling by glass drill on tile.
b) The auxiliary function on tile is only suitable to
be used under the hammer drilling position. When
operating under drilling/chiseling/ Adjust the chuck
angle mode, make sure to turn the auxiliary function
off .
8. FUNCTION MODE SELECTION (SEE FIG. D)
The operation of the gearbox for each application
is set with the function selector dial (4). To change
between functions, depress the unlocking button (a)
and rotate the selector to the desired operating mode.
Mode for simultaneous drilling
and impacting of concrete,
Masonry
Mode for or drilling into steel,
wood and plastics
Mode for or chiseling
", for drilling
", for removing the
Mode for adjust the chuck angle
of chiseling
NOTE: Select this function mode
first, adjust the chuck angle to
desired direction. Then select the
function mode to "
the chiseling work.
WARNING: The operating mode selector
switch may be actuated only at a
standstill.
9. OVERLOAD PROTECTION
When overloaded, the motor comes to a stop. Relieve
the load on the machine immediately and allow
cooling for approx. 30 seconds at the highest no-load
speed.
10. TEMPERATURE DEPENDENT OVERLOAD
PROTECTION
When using as intended for, the power tool cannot be
subject to overload. When the load is too high or the
allowable battery temperature of 75 °C is exceeded,
the electronic control switches off the power tool until
the temperature is in the optimum temperature range
again.
11. PROTECTION AGAINST DEEP DISCHARGING
The Li-ion battery is protected against deep
discharging by the "Discharging Protection System".
When the battery is empty, the machine is switched off
by means of a protective circuit: The inserted tool no
longer rotates.
WORKING HINTS FOR
YOUR TOOL
If your power tool becomes over heated, set the speed
to maximum and run no load for 2-3 minutes to cool
the motor. SDS-plus tungsten carbide drill bits should
always be used for concrete and masonry.
When drilling in metal, only use HSS drill bits in good
condition. Where possible use a pilot hole before
drilling a large diameter hole.

PROBLEM SOLUTION

1. REASONS FOR DIFFERENT CHARGING
TIMES
Your charge time can be affected by many reasons
which are not defects in your product. If the battery
pack is only partly discharged it may be re-charged
in less than 1 hour. If the battery pack and ambient
temperature are very cold then re-charging may take
1-1.5 hours. If the battery pack is very hot it will not re-
charge because the internal temperature safety cutout
will prevent it. If the battery pack is very hot you must
remove your battery pack from the charger and allow
your battery pack to cool first to ambient temperature
and then recharging can be started. If you charge a
second battery pack immediately after the first then
the charger can be overheated. Always allow at least
15 minutes rest between battery pack charging.
