LUBRICANT MAINTENANCE INTERVAL - The oil reservoir at the discharge end of the airend has a
capacity of approximately 32 oz. (.8 liters). The oil bath type lubrication utilized does not require an oil
filter or dedicated circulation hardware. As such, discharge end lubricant change intervals of 2000 hours
are recommended as the only maintenance requirement in lieu of filter changes and circulation system
maintenance.
NOTICE
IF OIL IS ANALYZED at the end of a maintenance interval (2000 hr. max.), and is
found in good condition, it may be used for the next 2000 hour interval – GD
provides free oil analysis services. OTHERWISE, IF OIL IS NOT ANALYZED at
the end of any interval, it must be changed.
The drive end bearings of the airend should be lubricated with the prescribed grease every 2000 hours of
operation until a small amount comes lightly out of the relief holes on the lower sides of the compressor
inlet end or on the inlet end cover.
During initial start-up and after regreasing, a small amount of grease may be ejected from the relief holes.
Wipe off any excess lubricant.
Severe operating conditions may require shorter regreasing intervals.
OIL LEVEL SIGHT GLASS -Figure 1-2, page 2) indicates the amount of oil in the airend oil reservoir.
Read the oil level when the unit is off. In operation the oil level may fluctuate.
Add oil only when the oil level drops into the lower half of the glass. Drain oil only when the compressor
is off.
