Landoll 5531 Grain Drill - Manual (Page 38)

4-10 F-716-1213 Edition
OPERATION AND MAINTENANCE
Compressor Operation
1. The Grain Drill is equipped with a small air
compressor to make minor adjustments in system air
pressure (See Figure 4-6.) When making large
adjustments in system pressure, use shop or
alternate air source.
2. Power to the electric air compressor is supplied
through the main lighting harness. Connect the
seven pin connector to the tractor. It is recommended
that the tractor be running while operating the
compressor to insure full system voltage to the
compressor. A toggle switch is located next to the
compressor to turn the compressor on and off.
3. Operate the compressor only when making small
adjustments to the system air pressure. Do not
operate the compressor while planting. The
compressor filter is not sufficient to operate in the
dirty field conditions. The compressor also has a
limited duty cycle. Maximum run time for the
compressor is 20 minutes on followed by a 20 minute
off cool down period before additional operation.
4. The air compressor is designed for oiless operation.
Thus there are no fluid levels to check or maintain.
