MAINTENANCE
Oil Requirements: We recommend a high quality automatic transmission
fluid such as Shell DONAX TG or equivalent
Filling the Pump with Oil:
1. Secure the pump in a vise by clamping lightly onto the hex body with the reservoir and
end cap facing upward, and unscrew the end cap.
2. Remove the rubber plug located in the center of the reservoir follower, and then remove
the reservoir follower. Check the reservoir follower O-ring and the rubber plug for damage
or wear, and replace as needed.
3. Fill the reservoir until the oil level is ¾" from the top.
4. Push the reservoir follower into the reservoir until oil begins to come out of the hole.
5. To remove trapped air from the pump, turn the release knob clockwise to the closed
position and pump the handle 5 times. Slowly turn the release knob counterclockwise
while keeping light pressure with your finger over the hole in the reservoir follower. This
allows air to escape under your finger and prevents ejecting oil. Repeat this procedure if
needed.
6. Replace the rubber plug in the reservoir follower.
7. Remove and clean the felt vent located inside the reservoir end cap. Then screw the
reservoir end cap back onto the reservoir.
