To refill the pulse unit
Keep the pulse unit at normal room temperature.
A
Before the refill: Let the bubbles in the oil fade away, at least 30 min. after last run.
Check that there are no bubbles in the oil and that the pulse unit is completely full (100%)
before reducing the oil volume according to operation No. 11.
Correct oil quantity: Fill to 100%, then reduce according to table.After
the refill - check the tightening torque, and pulse frequency according
to Test methods.

Important: Wait minimum

Position of stop pin
The "X" measurement is correctly set at our factory before delivery. Normaly the "X"
measurement has to be adjusted only after that the parts concerned have been dismantled.
If the accuracy is not as good as expected, check the position of the stop pin. The position
of the stop pin is adjusted by turning the screw (see fig. below).
The measurement "X" is hard to measure. It is possible to get the position by starting
from "X" = zero. Hold the pulse unit vertically and check that the stop pin is covering a
part of the centre hole (i.e. "X" is more than zero). Arrange the shut off valve in the centre
hole (see fig. below). Adjust the screw until the valve drops down in the hole of the stop
pin. In this position "X" is zero.
Place a gauge (i.e. a drill bit) with a diameter "D" according to table below in the hole.
Then unscrew the screw untill the gauge is just tight in the hole. Note: the gauge must not
be squeezed by the stop pin. Another way to get an appropriate "X" measurement is to
unscrew the screw from the position "X" = zero. Unscrew the No. of turns given in the
table below. The measurements given in the table will give a basic adjustment. Check the
diameter "D" with a drill bit or similar. An increased "X" means a higher tightening torque
and a decreased "X" means a lower tightening torque. It is possible to fine-adjust the
tightening torque by turning the screw. Change with an 1/8 of a turn at a time.
