7.2
CHANGING THE OIL.
7.2.1 change the oil following the initial 500 hours of use and then
every 2500 hours thereafter, or at least once a year.
In case of infrequent use (only a few hours of duty per
day) you should change the oil every 6 months.
7.2.2 referring to fig.14 identify the oil filler cap (1) and the oil drain
tap (2). unscrew the oil filler cap (1) and put to one side.
Ensure that the oil drain tap is shut off (i.e. tap handle at 90° to
the body of the tap). Have to hand a pipe and container ready
to collect the oil.
7.2.3. unscrew the hex nut from the end of the oil drain tap. screw in
the tail piece attachment supplied with the compressor. Push
the pipe onto the tailpiece and ensure that the other end is in
the collection container. open the drain tap fig.14-2. once
emptied, close tap, remove the tail piece attachment and
screw the hex nut (with seal) back into place.
7.2.4. fill-up with oil as shown in fig.15 until the level is halfway up
the sight glass. see fig.15-3. screw oil filler cap (1), with its
seal, back into the oil filler hole.
7.2.5. once the oil and oil filter have been changed follow the initial
start up procedure by pressing the stArt & stoP buttons on
and off for 3 or 4 seconds to start the machine intermittently.
After this, leave the compressor to run for roughly 5 minutes
then turn it off and check the oil level again. Check the oil
level once a month.
7.2.6. never mix different types of oil, therefore always ensure that
the circuit is completely empty before filling-up with oil. Each
time the oil is changed the filter is also to be replaced.
