Action
Make a rough alignment
of pump and motor, and
tighten the screws in the
base frame to the
correct torque. See the
table Tightening torques
on page 18.
Fasten one laser
bracket to the pump
coupling.
Fasten the other laser
bracket to the motor
coupling.
Place laser unit S,
stationary, on the
stationary part and laser
unit M, movable, on the
movable part.
Interconnect the laser
units, and connect one
laser unit to the control
box.
Make sure that the laser
units are at the same
height.

Action
Measure the distance
between the white lines
on the laser units.
Enter the distance.
Measure the distance
between the S unit and
the centre of the gap
between the couplings.
Enter the distance.
Measure the distance
from the S unit to the
first screw on the motor.
Enter the distance.
