Action
Make a rough alignment
of pump and motor, and
tighten the screws with
correct torque in the
base frame. See the
table "Tightening
torques".
Fasten one laser bracket
on the pump coupling.
Fasten the other laser
bracket on the motor
coupling.
Laser unit S (Stationary)
is on the stationary part.
Laser unit M (Movable)
is on the part that is
moved.
Interconnect the laser
units, and connect one
laser unit with the control
box.
Make sure that the laser
units are at the same
height.
