Speed control
By light and gradual pressing the controller button (4) you will achieve low
speed and controlled continuous run-up.
By further gradual pressing the button the speed increases to the
pre-selected speed.
Electronic speed pre-selection
Using the pre-selection wheel (5) the required pre-selected speed is set–even
if the machine runs. The necessary speed depends on the type of the material
drilled, and a practical test is recommended to verify it.
If the machine is loaded considerably, adjust the pre-selection wheel (5) to the
marginal position in the + direction (max speed – control disconnected).
After a longer work at low speed leave the machine run idle for 3 minutes at
maximum speed to cool the engine down.
Gear shifting (EVP 16-2F3)
Use the speed lever (7) to adjust the 2nd speed gear:
1. Speed – lower speed gear – higher torque
2. Speed – higher speed gear – lower torque
In any speed gear you can adjust the final speed by means of the electronic
pre - selection. However, firstly select the mechanical speed gear.
Changing the gears can be done at slowing the machine down or in idle run
but never when the machine is fully loaded . Once the gear is changed,
leave the machine start up slowly.
Drilling and impact drilling (EVP 16-2F3)
Shift in or out the hammer by the hammer gear button (8). The shifting can
be done even when the machine runs.
Shift in or out the hammer by the hammer gear button (8).
Drilling:
Pull the button (8) in the direction of the symbol - drill.
The impact drilling is recommended to be used in concrete, brickwork and
earthenware. Axial spindle backlash - to 2.5 mm. Radial backlash measured
on the pin clamped in the chuck within the spacing range of 50 mm
to 0.3 mm.
Removing the chuck with ring gear
Hold the spindle on the surface (12) using an open wrench (22 mm). Insert
the chuck hook (11) into a single opening on the chuck and by turning left
screw the chuck out. Release the firmly clamped chuck by impacts of the
hammer on the chuck hook (11).
Work instructions
Drill bits
For steel use perfect and sharpened drill bits made of good-quality
high - speed steel.
Drilling stands
For precise drilling on smaller parts, use of a drilling stand is recommended.
Clamping device
Clamp the worked pieces properly into the screw-type clamping unit. Thus
turning of the piece is avoided, as well as a potential accident.
Drilling in tiles
Shift the impact gear lever (8) to the drill-bit symbol. Once the upper layer is
drilled through, shift the impact gear lever to the hammer symbol .
Maintenance
The vent holes (5) of the engine cover must not get plugged.
After about 100 hours of operation the following works need to be
done:
- Check of the brushes length Brushes shorter than 5 mm must be
replaced with new ones.
After about 200 hours of operation the following works need to be
done:
- Exchange of lubricating grease in the gearbox and bearings.
To keep the protection class the machine needs to be checked in terms
of safety, and therefore these works must be carried out in an authorised
electric workshop holding the relevant licence to perform these kinds of
activities.
Storage
Packed appliance may be stored in dry, unheated storage place with
temperature not lower than –5°C.
Unpacked appliance should be stored only in dry storage place with
temperature not lower than +5°C with exclusion of all sudden temperature
changes.
