Correct working temperatures and pressures
8.8.1
Working temperatures
The motor compressor is designed to work at the following temperatures:
•
Maximum ambient temperature: 40ºC, for higher temperature seek advice.
•
Maximum mixture discharge temperature: 110ºC. At this temperature the unit stops
automatically.
When the unit starts up in a cold temperature (below 5ºC), as a result of the high viscosity of the oil at
this temperature, there may be some saturation of oil as it passes through the separator and oil filters. As a result
the safety valves may activate, with slight oil expulsion into the network and even a lack of lubrication oil
injection in the rotor. It is also necessary with temperatures lower than 5º C to use oil with ISO VG46 viscosity
and freezing point lower than -20ºC.
8.8.2
Working pressures
This unit is designed to provide a pressure of 7.0 bar at the point of air outlet of the machine. This
reading is made on the pressure gauge where it indicates “WORKING PRESSURE”.
Regulation occurs at 7.5 bar, with the differential pressure of regulation being 1 bar, that is,
6.5 bar - 7.5 bar.

Maintenance
9.1
Safety Indications for maintenance and repair
Maintenance and repair work should only be carried out by expert personnel, given the case, with the
supervision of a qualified specialist in this type of work.
1.
Use the correct tools for maintenance and repair work t
2.
Use only original UTIFORM spare parts.
9.2
Safety indications for using tools
Use the adequate tool for each job. If the tools are used in an appropriate and reasonable manner, and
their limitations are taken into account, many accidents can be avoided.
For specialized work, special tools may be obtained. Using these tools saves time and avoids damaging
the machine parts.
1.
Only use spanners for screws and bolts or box spanners with a perfect fit.
2.
Only use a forked spanner at the flat level of the screw head vertical in the thread. Never use a
forked spanner crossways.
3.
Never use a pipe or other type of improvised rod to extend a handle.
4.
Never hit wrenches or other tools not for this purpose.
5.
Secure the head of the ratchet wrench if extension is necessary.
7.
Do not use wrenches with broken or worn points or edges.
8.
Use high powered couplings for compressed air or hitting tools.
