OPERATION INSTRUCTIONS
IMPORTANT: DON'T USE PNEUMATIC OR
POWER TOOLS WITH THE MULTIPLIER.
1. Connect the reaction anchor to the gearbox
housing. Make sure that the locking pin snaps
into the anchor
(in confined spaces the device can also be used
without the reaction anchor).
2. Put an impact socket on the male square
drive of torque multiplier and lock it with pin
and ring.
3. Put torque multiplier with fixed impact sock-
et over the bolt connection to be moved.
4. On devices URREA 6222 and 6232 set work-
ing direction required by moving selection
pawl of anti-backlash-device on L = left hand
operation (dismounting) or on R = right hand
operation (tightening).
5. Take care that reaction anchor finds a stable
counter stay. Attention: reaction anchor moves
opposite to working direction.
6. Adjust your torque wrench to the input
torque value necessary to achieve the required
output torque .
7. Now put torque wrench onto torque mul-
tiplier and tighten up to the pre-set input
torque value. Do neither hold reaction anchor
nor torque multiplier with your hands, the
forces that are created during operation may
lead to injuries.
8. On devices URREA 6222 and 6232 the plan-
etary gear system must be discharged when
operation is finished. This is done by shortly
loading torque multiplier into working direc-
tion and putting the selection pawl into neu-
tral position (0). Then carefully discharge.
CAUTION:
1. Only use torque wrenches.
2. Never use pneumatic or power impact tools.

3. Please make sure that the reaction bar is
properly placed against a strong fixed object.
4. The same procedure used for tightening
screw connections applies to loosening screw
connections.
To protect the planetary gear we also recom-
mend using only torque wrenches.
Adjust the maximum input torque of your UR-
REA-torque multiplier to the torque wrench.
Shear-off-system:
In order to protect gear system against over-
loading all URREA-torque multipliers are fitted
with a controlled shear-off system.
Sheared off pins can easily be replaced by user
at working site.
MAINTENANCE
1. The torque multiplier's internal mechanism
is permanently lubricated during assembly. Do
not attempt to lubricate the internal mecha-
nism.
2. Clean multiplier by wiping. Do not immerse.
3. Store torque multiplier in its protective case
after operation.
