Operating Instructions
barrel, which has to be pressurized first. You
may alternatively connect the device to a
water tap, using the "Gardena" hose
couplings. Maximum water pressure is
60 psi / 4 bar.
5. Finally connect the tool to the power source.
6. Move the hydraulic circuit control valve to the
ON position.
7. To operate the drill, regulate check valve to
adjust the water supply flow as desired.
8. With the so prepared drill, you may now
proceed to carry out your work.
9. Squeeze the trigger to activate the drill and
press valve trigger fixing key to ensure
comfortable working.
CAUTION
Monitor continuously the water supply to ensure that
sufficient water is supplied to the cut surface to avoid
unnecessary wear of drilling equipment.
10. You may continuously control the advance
motion of the drill by adjusting the star knob
at the side of the drilling stand.
11. To switch off the machine, unlock the valve
trigger fixing key. Then, shut off the water
supply.
12. To change drill bits, proceed as described
above. Adhere to safety instructions!
13. For dismounting the drill upon completion of
drilling work, follow the mounting
instructions in reverse order.

CAUTION
When drilling into a structure that might contain
electrical wiring, be sure to know the location of the
wiring and avoid drilling into it. The housing can carry
electrical current from live electrical wires into which
the drill is accidentally drilled resulting in injury or
death.
Cold Weather Operation
If the drill is to be used during cold weather,
preheat the hydraulic fluid at low engine speed.
When using the normally recommended fluids,
fluid temperature should be at or above
50 °F/10 °C (400 ssu/ 82 centistokes) before use.
Damage to the hydraulic system or drill can result
from use with fluid that is too viscous or too thick.
