TIGHTENING OF HEAD TENSION RODS
See Figure 11.
Check that all screws (in particular those of the head of
the unit) are tightly drawn up.
The check must be carried out prior to the first
compressor starting. And after the first hour of work.
Tightening values for the tension rods of the head:
Nm min. torque
= 22
Nm max. torque
= 27
CLEANING THE INTAKE FILTER
See Figure 12.
The intake filter prevents dust and dirt being drawn in.
It is essential to clean this filter after at least every 100
hours in service. A clogged intake filter will decrease the
compressor’s performance dramatically. Undo the two
allen screws (Figure 18). You can then remove the filter
from the two halves of the plastic housing, tap it to remove
the dirt, blast it down with low-pressure compressed air
(approx. 3 bar) and re-insert it (Figure 12).
