7.11 12 Volt Battery
If the compressor is equipped with a genuine Airmac 12 Volt battery kit, the battery is a sealed-for-
life type that requires no regular maintenance. It is automatically charged whenever the compressor
is running.
The battery will self-discharge slowly when not in use and after some time it may have insufficient
charge to start the compressor. To prevent this inconvenience, one can either run the compressor
periodically to keep the battery charged sufficiently or otherwise charge it (when the compressor is
not operating) using a mains-powered 12 Volt battery charger.
Ensure correct polarity whenever charging or re-connecting the battery as described in the
Installation section.
7.12 Oil Fill Quantities
Please note that the values listed in Table 7-2 are approximate only. Always check the compressor
pump’s oil level using the crankcase sight glass as described earlier in this section.

7.13 Engine Speed
The maximum engine speed on both petrol and diesel-powered models has been pre-set at
approximately 3,600 rpm with the compressor in “loading” mode at either 900 kPa for single- stage
compressor pumps or 1,100 kPa for two-stage compressor pumps. Do not adjust the engine speed
higher as this may cause damage due to increased vibration, which is not covered by warranty.
Should it ever be necessary to re-set the maximum engine speed in accordance with the above
specification, it is recommended to apply Loctite® threat sealant onto the engine’s high idle set screw
to prevent it from vibrating out of adjustment.
