– Hit on the filter cartridge using the palm of your hand to knock out coarse
dust.
– Blow out fine dust from the inside to the outside using dry compressed
air (maximum pressure 72.5 psig).
– Clean the sealing surface of the filter cartridge.
Fitting a filter cartridge
– Insert filter cartridge into the filter housing.
– Attach lid of the filter housing.
Drive motors with
permanent lubrication
As a rule, the bearings of the drive motors are provided with a maintenance
free permanent lubrication.
Under normal operating conditions (coolant temperature max. 104°F, conti-
nous operation) the bearings are maintenance free for the service life.
For motor maintenance see operating instructions of the compressor comtrol.
The service life decreases or increases as thermal stress increases or de-
creases (due to increased or reduced coolant temperature).
Checking the oil level,
topping up oil
Check:
– Prior to commissioning/start-up of the compressor.
– Then every 1,000 operating hours, however at least once a year.
Topping up:
– If the oil has dropped to a level 0.4 – 0.8 inch below the bottom edge of the
thread.
– Switch off the compressor using the OFF button.
Attention!
Have BOGE service dismantle the bearings and install new bearings once
the specified service life has expired.
Attention!
Always use the same oil type when topping up. Never mix different oil types
and brands.
Caution: Risk of injury!
Press Emergency Stop button, open mains disconnection device and secure
against unintentional switch on by means of a padlock.
