MAINTENANCE
.
Adding Oil to the Pump
Check oil level regularly.
WARNING
Always add oil with cylinders fully retracted (extended if pull
cylinders) or the system will contain more oil than the reservoir
can hold.
1.
Remove vent/fill cap from reservoir.
2.
Fill reservoir only to level mark shown on pump.
3.
Remove air from system if necessary. Recheck oil level after removing air.
4.
Return vent/fill cap to proper position.
NOTE:
Non-vented hand pumps require air in the reservoir to function properly. If the
reservoir is completely filled, a vacuum will form preventing oil from flowing
out of the pump.
Keeping Oil Lines Clean
When coupler halves are disconnected, always screw on dust caps. Use every
precaution to guard unit against entrance of dirt because foreign matter may cause
pump, cylinder, or valve failure.
Lubricating the Pump
To extend pump life and improve performance, lubricate the beam pin (A), cross pin
(B), and piston head (C) regularly, using roller bearing grease. See Figure 4 below.
