A3.2 Fill the pump with oil
Fill the pump with oil as described below. Refer to Figure A2 for the item numbers in brackets.
1. Unscrew and move aside the pipe on the dry nitrogen non-return valve (5) on top of the oil-box. Remove the
non-return valve.
2. Pour oil into the pump until the oil-level just reaches the MAX mark on the bezel at the top of the sight-glass. If
the oil-level goes above the MAX mark, open the oil drain tap and drain the excess oil from the pump. You will
need additional oil if an external oil nitration unit is fitted. Refer to the instructions supplied with your filter;
see Associated publications on contents page iv of this manual.
3. After a few minutes, recheck the oil-level. If the oil-level is now below the MAX mark, pour more oil into the
pump.
4. Screw the non-return valve (5) back into the oil-box and tighten down firmly; re-connect the pipe.
WARNING
Prevent direct skin contact with the oils and greases in this pump. Use suitable protective clothing.
These oils can cause inflamation of the skin after prolonged contact.
