BEFORE STARTING
1. Before initial start-up, prepare battery for
operation if not already done. See section
Recharging a battery .
2. Check that the draining caps in the spillage-free
frame are firmly tightened.
3. With the compressor standing level, check the
level of the engine oil. Add oil, if necessary, up to
the upper mark on the dipstick. Also check the
engine coolant level. Consult the Engine
Operation Manual for the type of coolant and type
and viscosity grade of the engine oil.
4. Remove the air receiver drain plug (1), see figure,
and open the valve to drain possible condensate.
Close the valve when oil comes out and reinstall
the drain plug. The interval between draining
operations may be determined by experience, as
the amount of condensate depends on the
operating condition.
5. Check the level of the compressor oil. See section
Check compressor oil level . The pointer of the
oil level gauge (OLG) should register in the green
range. Add oil if necessary. See section
Compressor oil for the oil to be used.
