FAQs

What maintenance is recommended for these Hydraulic Power Units?

Every 2-3 months, check electrical connections for corrosion and tightness from unit to battery. Check the fluid condition and level. Inspect the breather/filler cap as well for missing foam or dirt. Every year we recommend changing out your hydraulic fluid.

What fluid is recommended in this Hydraulic Power Unit?

We recommend ATF (Automatic Transmission Fluid) for almost every case. In very low temperatures (Below -20°F / -30°C) the ATF will thicken. In this cold weather, ensure the reservoir is filled to the recommended level and consider preheating the fluid or using a reservoir heater.

Can I use this hydraulic power unit to run my hydraulic winch?

Short answer: No. Long answer: Yes, but it will be a slow, sad, and disappointing experience. While the operating pressure is often correct, the 1.5 gpm (gallons per minute) vs the 15 gpm of a clutch or PTO pump is going to be a tenth of the performance you'd want at best.
