Oil Filter Replacement (Compressor) - Bottarini GDP21 Maintenance And Operating Manual

9. Maintenance
9.5.1 Oil filter replacement
(compressor)
Fig. 33
Danger
Only replace the oil filter cartridge
when the engine is at a standstill and
the screw compressor is not under
pressure.
Caution with hot oil: risk of scalding!
Spill no oil!
Attention
Change the oil filter every 1,000 oper-
ating hours, but at least once per year.
Note
Dispose of oil filter cartridge in accordance
with the relevant regulations - hazardous
waste!
Check for leaks.
Changing the oil filter:
* Unscrew the oil filter cartridge using
appropriate tools
* Dispose of oil filter cartridge
* Apply a thin coat of oil to the seal of the
new oil filter cartridge
* Screw on and tighten the new oil filter
cartridge (follow the instructions on the
oil filter cartridge)
* Check for leaks
* Check oil level, add oil if necessary
9.5.2 Oil change (compressor)
Fig. 34
Danger
Only change the oil when the engine is
at a standstill and the system is not
under pressure.
Caution when draining off hot oil:
risk of scalding! Spill no oil!
Attention
Change the oil filter every 1,000 oper-
ating hours, but at least once per year.
The screw compressor must not be
under pressure during oil change.
Drain the oil at operating temperature.
Do not mix oils of different
specifications.
Note
Collect used oil, do not allow it to enter the
soil. Dispose of oil in accordance with the
relevant regulations - hazardous waste!
Spill no oil! Check for leaks.
Changing the oil:
* Unscrew dipstick
* Place oil drain pan under oil drain valve
* Unscrew the sealing cap of the
pressure vessel
* Collect used oil in the oil drain pan
* When the used oil has been drained
completely, use a new sealing ring on
the sealing screw of the pressure
vessel, position and tighten screw or
close the oil drain valve
* Fill up with new oil (see section
"Specifications" in chapter 1 for initial
oil capacity; use a little less oil when
performing an oil change).
* For lubricants see "Lubricant Table"
* Check sealing ring on dipstick, replace
if necessary
* Screw in and tighten dipstick
* Start screw compressor, run for approx.
two minutes, check for leaks
* Switch off screw compressor
* Check oil level, add oil if necessary
9.5.3 Checking the automatic
monitoring system
Danger
Interference with the automatic
monitoring system is not permissible!
Check individually every 1000 operating
hours:
1.
Temperature sensor - screw
compressor (pressure connection)
2. Oil pressure switch - engine
3. Oil temperature gauge - engine
4. Fuel shortage
Checking the automatic monitoring
system:
1. Compressor temperature controller
Bridge connections
1.1
Start the compressor, the system must
shut down after completion of the
automatic function test of the engine
monitoring system.
The fault is indicated by illumination of
the LED
2.
Engine oil pressure transducer
Connect to earth (ground)
2.1 Proceed as for 1.1
3. Engine temperature transducer
Connect to earth (ground)
3.1 Proceed as for 1.1
4. Engine temperature transducer
Bridge connections
4.1 Proceed as for 1.1
Attention
Correct functioning of the engine
monitoring system must be restored
after completion of the check!
