Maintaining a hydraulic floor jack is essential for garage safety and performance, especially in the extreme heat of Phoenix, Arizona. Over time, hydraulic oil degrades or evaporates, leading to spongy lifting or a jack that fails to hold weight.
Here is a simple guide to locating the fill plug and topping off your floor jack correctly.
Step-by-Step: Locating and Adding Hydraulic Fluid
- Lower the Jack Completely: Turn the release valve counterclockwise to ensure the lifting arm is fully lowered before starting.
- Remove the Cover Plate: Unbolt or slide off the metal inspection plate located on the main body of the floor jack.
- Locate the Oil Filler Plug: Look at the main hydraulic cylinder (the reservoir). You will see a small rubber plug or threaded screw on top or along the side.
- Clean the Area: Wipe away dust, desert grit, and grease around the plug so debris doesn’t fall into the reservoir.
- Remove the Fill Plug: Carefully pry out the rubber plug or unscrew it with a flathead screwdriver.
- Fill with Hydraulic Jack Oil: Pour standard hydraulic jack oil into the port using a small funnel until the oil reaches roughly 1/8 to 1/4 inch below the fill hole rim. (Do not use motor oil or brake fluid.)
- Bleed Trapped Air: Leave the plug loose, pump the handle 10–15 times with the release valve open to purge air bubbles, then tighten the plug back down.
