LUBRICATOR
OPERATION
The lubricator comprises a pump and a reservoir.
The reservoir holds max 45 cc of oil (effective oil
volume is 28 cc).
Use mineral oil 22-32 cSt at 40°C (Eg. Tellus oil
No.32). To operate the lubricator:
1. First unscrew the reservoir cap by half a turn. Do
not remove the cap completely.*
2. Push the button to its lowest position (stroke: 12
mm).
3. When released, the button will automatically re-
turn to its original position.
4. Lastly, tighten the cap to prevent oil leakage dur-
ing operation.
MAINTENANCE
1. Keep off dust or foreign matter when filling reser -
voir (may cause jamming of piston and check the
valve).
2. Rate of discharge is fixed and not adjustable
(0.08cc per push).
3. At high temperatures, grease may run along
points (A). This is normal grease used during
assembly of lubricator in our plant.
4. Keep oil reservoir (high density polyehylene)
away from fire and do not use organic, benzene
or xylene chemicals for cleaning.
Regularly check the correct function of the oil
pump (Repeat oil feed and check oil through the
discharge pipe).
