The RJ45W includes a high-pressure hydraulic power unit attached to the jack, with an air requirement of 125 psi and 10 to 20 CFM. A foot pedal mounted directly to the unit gives the operator simple control during lifting, keeping bridge jack operation separate from the four-post lift power system. Three lock positions let users fine-tune service height for the work at hand. Whether the job calls for quick tire removal, brake access, or extra undercarriage clearance, the RJ45W gives HD-9 owners a practical way to get more service capability out of the lift they already use every day.
