Adding Oil to the Pump

WARNING: Always add oil with cylinders fully retracted (extended if pull cylinders) or the system will contain more oil than the reservoir can hold.

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.

Remove vent/fill cap from reservoir.

Fill reservoir only to level mark shown on pump.

Remove air from system if necessary.

Recheck oil level after removing air.

Return vent/fill cap to proper position.

Sign off on the oil addition to the pump.
