Operating Instructions
Check Power Source
Connect Hoses
1. Using a calibrated flowmeter and pressure
gauge during the intial set-up, check that the
hydraulic power source develops a flow of 4-
12 gpm/ 15-45 lpm at 1000-2000 psi/ 70-140
bar.
2. Make certain that the hydraulic power source
is equipped with a relief valve set to open at
2100 psi/ 145 bar maximum.
1. Wipe all hose couplers with a clean lint-free
cloth before making connections.
2. Connect hoses from the hydraulic power
supply to the tool quick disconnects. It is a
good practice to connect the return hose first
and disconnect it last to minimize or avoid
trapped pressure within the drill.
3. Observe the arrow on hose couplers to ensure
that the flow is in the proper direction. The
male coupler on the circuit hose end is the
supply (pressure) coupler.
4. Make sure the circuit PRESSURE hose (with
male quick disconnect) is connected to the
port at the back of the drill handle. The circuit
RETURN hose (with female quick disconnect)
is connected to the port closest to the trigger.
5. Move the hydraulic circuit control valve to the
position to direct hydraulic flow to the
drill.
ON
5. Press the drill against the work and squeeze
the trigger.
The drilling method used is determined by the
material being drilled and the size and depth
requirements of the hole.
Ductile material such as metal or wood is drilled
efficiently when a steady down force is applied to
the drill center to cause the bit to slice chips of
material from the hole bottom. When drilling in
metal, use a cutting lubricant to prolong bit life
and reduce the amount of force required to drill
effectively.
Large drill holes are more productively created
from small drill holes. Drill bits are incrementally
selected to enlarge the hole until the desired hole
size is obtained. Each bit selected must always be
too large to thread and jam into an existing hole;
otherwise the bit may break and endanger the
operator.
NOTE: If uncoupled hoses are left in the
sun, pressure increase inside the hose
may result in making them difficult to
connect. Whenever possible, connect the
free ends of the hoses together.
Drill Operation
1. Observe all safety precautions.
2. Place the selected drill bit fully into the chuck.
Center the bit and tighten the chuck using the
key provided. Remove the key and store away
from the drill.
3. Momentarily press the trigger to ensure that
the drill bit rotates clockwise and runs true.
4. Select a work position that gives secure
footing and balance while operating the drill.
CAUTION
Make certain that the chuck has been securely mounted.
