To remove the screwdriver bit from the bit holder, lift the bit
u
from the recess.
To store the screwdriver bit, firmly push it into the holder.
u
Use
Warning! Let the tool work at its own pace. Do not overload.
Charging the battery (fig. A)
The battery needs to be charged before first use and
whenever it fails to produce sufficient power on jobs that were
easily done before. When charging the battery for the first
time, or after prolonged storage, it will only accept an 80%
charge. After several charge and discharge cycles, the battery
will attain full capacity. The battery may become warm while
charging; this is normal and does not indicate a problem.
Warning! Do not charge the battery at ambient temperatures
below 4 °C or above 40 °C. Recommended charging
temperature: approx. 24 °C.
Using the 3 hr charger
To charge the battery (7), remove it from the tool and slide
u
the charger receptacle (10) onto the battery.
Plug in the charger (9).
u
The battery will become warm while charging. After approx. 3
hours of charging, the battery will be sufficiently charged for
use in regular applications. After approx. 6 hours of charging,
the battery will be fully charged.
Remove the charger receptacle from the battery.
u
Using the 1 hr charger
To charge the battery (7), remove it from the tool and
u
insert it into the charger (9). The battery will only fit into
the charger in one way. Do not force. Be sure that the
battery is fully seated in the charger.
Plug in the charger.
u
Check if the red charging indicator (11) lights up.
u
After approx. 1 hour of charging, the red charging indicator (11)
will stop lighting. The battery is now fully charged.
Remove the battery from the charger.
u
Selecting the direction of rotation (fig. E)
For drilling and for tightening screws, use forward (clockwise)
rotation. For loosening screws or removing a jammed drill bit,
use reverse (counterclockwise) rotation.
To select forward rotation, push the forward/reverse slider (2)
u
to the left.
To select reverse rotation, push the forward/reverse slider
u
to the right.
To lock the tool, set the forward/reverse slider into the
u
centre position.
Selecting the operating mode or torque (fig. F)
This tool is fitted with a collar to select the operating mode and
to set the torque for tightening screws. Large screws and hard
workpiece materials require a higher torque setting than small
screws and soft workpiece materials. The collar has a wide
range of settings to suit your application.
For drilling in wood, metal and plastics, set the collar (4) to
u
the drilling position by aligning the symbol with the
marking (16).
For screwdriving, set the collar to the desired setting. If you do
u
not yet know the appropriate setting, proceed as follows:
- Set the collar (4) to the lowest torque setting.
- Tighten the first screw.
- If the clutch ratchets before the desired result is
achieved, increase the collar setting and continue
tightening the screw. Repeat until you reach the correct
setting. Use this setting for the remaining screws.
HP188F4 - Drilling in masonry (fig. F & G)
For drilling in masonry, set the collar (4) to the hammer
u
drilling position by aligning the symbol with the marking
(16).
Slide the two-gear selector (5) towards the front of the tool
u
(2nd gear).
Two-gear selector (fig. G)
For drilling in steel and for screwdriving applications, slide the
u
two-gear selector (5) towards the rear of the tool (1st gear).
For drilling in materials other than steel, slide the two-gear
u
selector (5) towards the front of the tool (2nd gear).
Drilling/screwdriving
Select forward or reverse rotation using the forward/
u
reverse slider (2).
To switch the tool on, press the switch (1). The tool speed
u
depends on how far you press the switch.
To switch the tool off, release the switch.
u
Hints for optimum use
Drilling
Always apply a light pressure in a straight line with the drill bit.
u
Just before the drill tip breaks through the other side of the
u
workpiece, decrease pressure on the tool.
Use a block of wood to back up workpieces that may splinter.
u
Use spade bits when drilling large diameter holes in wood.
u
Use HSS drill bits when drilling in metal.
u
Use masonry bits when drilling in soft masonry.
u
Use a lubricant when drilling metals other than cast iron
u
and brass.
Make an indentation using a centre punch at the centre of
u
the hole to be drilled in order to improve accuracy.
