Safety checks
• Before working on any circuit or component, it is OBBLIGATORY to
check for residual voltage or pressure in the systems, making sure to
always work in safe conditions.
• Risk of bumping into the machine structure and parts. Move cautiously
while carrying out maintenance.
•
Risk of slipping, tripping and falling on machining scraps.
Move cautiously while carrying out maintenance.
• Risk of dust and materials being flung or sucked in.
• In addition to commonly used PPE, based on the maintenance being
carried out also use one of the following:
, PVC coveralls;
; , .

Check
Check the lubricant oil level in the tank.
Keep the tank full (electrical minimum level signal). If the oil pump works
with the tank empty, air may get pumped into the lubrication system; this
may make it difficult to keep the pumping pressure up and may keep the
pump from priming
.
3
Visual inspection
Inspect the entire system, including rigid and flexible pipes (replace if
damaged), couplings (must be sealed) and all the bearings (a small
amount of lubricant should be visible along the edge of each bearing).
Check that the lubricating pump is working properly.

INFORMATION!
• Risk of damage to the machine.
It is essential to bleed all the air from the system. Correct pressure readings depend on
the circuit being full of lubricant. Distributors that have air trapped inside them cannot
signal clogged points. To eliminate all the air from the system, follow the bleeding
procedure described in the attached manual.
