Draining separator receiver tank
After stopping the engine, confirm that the pressure gauge
indicates 0 psi (0 bar) and there is no residual pressure in it,
then open the drain valve gradually to drain the compressor oil.
Note residual pressure in the separator receiver tank could
force both extremely hot compressed air and oil to jet out and
you may be scalded or seriously injured.
H990432
Be careful of high-pressurized air blowout
After stopping the engine, make sure that pressure gauge
indicates 0 psi (0 bar). Even when the gauge shows 0 psi (0
bar), open a service valve and further do not fail to make sure
that there is no residual pressure in the air piping. Then begin
repair and maintenance.
Residual air under pressure can cause severe injury.

If the machine is running, it might catch the operator’s hand
into the fan belts, and this could cause a serious injury.
