3.5 Fill the pump with oil
Fill the pump with oil as described below. Refer to Section 2 for the recommended oil.
1. Remove one of the oil filler-plugs ( Figure 1 , item 7).
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 (8).
If the oil level goes above the MAX mark, remove the drain plug (9) and drain the excess oil from the pump.
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. Refit the oil filler-plug. Tighten the plug firmly by hand. Do not overtighten.
3.6 Fit the outlet oil mist filter
1. Ensure that the pump outlet ( Figure 4 , item 17) is clean, then place one of the Co-Seals (15) on the outlet.
2. Place the oil mist filter inlet (14) on the pump outlet so that the flow arrow on the lower half of the filter body
(see Figure 8 ) points upwards away from the pump outlet and the drain plug points towards the oil filler plugs
(as shown in Figure 5 ).
3. Use one of the clamping rings ( Figure 4 , item 16) to secure the oil mist filter to the pump.
4. Use another Co-Seal (3) and clamping ring (2) to secure one of the elbows (4) to the mist filter outlet (12);
ensure that the horizontal part of the elbow points towards the front of the pump (as shown in Figure 3 ).
5. Use another Co-Seal (5) and clamping ring (6) to secure the other elbow (8) to the elbow already fitted; ensure
that the free end of the elbow points vertically downwards (as shown on Figure 4 ).
6. Use another Co-Seal (9) and clamping ring (10) to secure one of the hose adaptors (11) to the elbow.
3.7 Fit the gas ballast oil return assembly
1. Remove the drain plug ( Figure 8 , item 4) from the drain port on the oil mist filter.
2. Fit the drain adaptor (Figure 5, item 8) to the drain port on the oil mist filter.
3. Turn the gas ballast control on the pump ( Figure 4 , item 18) to position ‘II’. Push the control down (against the
spring), turn the control anticlockwise to release it, then remove the control from the pump. Leave the spring in
position in the gas ballast port in the pump.
4. Lift the pump handle ( Figure 1 , item 15). Fit the oil return assembly ( Figure 5 , item 5) to the gas ballast port on
the pump, push the assembly down (against the spring) and turn the assembly clockwise to secure it to the
pump. When the assembly is correctly secured to the pump, the nozzle (4) should be over position ‘0’ marked on
the top of the pump (see detail B).
5. Cut a suitable length from the flexible oil-return tube. The routing of the tube (3) must be approximately as
shown in Figure 5 . When fitted, the tube must not be taut and there must be no tight bends in the tube. Ensure
that the ends of the oil-return tube are free of burrs and that they are squarely cut (that is, the cut faces are at
a right angle to the length of the tube).
6. Fit the restrictor (7) into the end of the tube, then fit the same end of the tube to the drain adaptor on the oil
mist filter.
7. Fit the other end of the tube to the nozzle (4) on the oil return assembly (5).
8. Use the hose clips (2) to secure the ends of the flexible oil-return tube (3).
