PRESSURE CHECK INSTRUCTIONS
When performing a pressure check on a SwapLoader hook-lift hoist, we recommend that you
use a calibrated pressure gauge that reads pressures up to 3,500 PSI (a 0 to 5,000 PSI range
gauge is recommended). As a minimum, the gauge should have 100 PSI graduation marks (50
PSI is preferred), and a 3 inch diameter dial size (4 inch dial is preferred). The pressure gauge
should be outfitted with a female JIC #4 hydraulic adapter; preferably located at the end of a 3/8
inch diameter high pressure hydraulic hose that is 2 to 3 foot in length (see illustration below).
Should you not be able to source a hydraulic gauge locally, SwapLoader can provide one at a
reasonable cost (Hyd. Pressure Gauge & Hose Assembly – Pt. No. 22P10).
PRESSURE CHECK STEPS
1. Locate the 90° male JIC #4 hydraulic adapter (SWL #10P37) found on the top of the hoist
hydraulic control valve (see illustration below).
