Operation
7.1 Before using the pump
1. Check all system fittings and connections to be sure they are tight and leak free.
2. Check oil level in reservoir before operating pump (see chapter 7.1 "Adding oil to the pump").
CAUTION: NEVER add extensions to pump handle. Extensions cause unstable pump operation.
WARNING: In certain situations the pump handle can “kick back”. Always keep your body to the side of
the pump, away from the line of force of the handle.
NOTE: To reduce handle effort at high pressure, take short strokes. Maximum leverage is obtained in the
last 5° of stroke.
7.2 Using two-speed pumps
These pumps provide 2-stage flow. Under no-load, the pump operates in the high flow first stage for rapid
advance. When the load is contacted, the pump automatically shifts to the second stage for building
pressure.
NOTE: For best performance, operate pump handle at moderate speed during the high flow first stage.
Rapid handle speed in the first stage will prevent the pump from delivering full volume of oil.
7.3 Single-acting applications with release valve
1. Close release valve by turning clockwise, as shown in figure 3.
