Operating Instructions

on the relief valve, you may overwork the unit. This can cause the unit to fail suddenly, and you may be hurt.

4.Clean up any spilled hydraulic fluid. Spilled hydraulic oil is slippery, and may present a fire hazard. If you clean up any spilled fluid, you will be able to tell right away if the unit begins to leak.

5.Figure 1 shows the safety labels on this unit. Check to be sure all of the labels are in place.

Safety Instructions

DANGER!

The unit uses a power supply of 115 Volts AC. This voltage can kill you.

DON’T WORK WITH THE ELECTRICAL PARTS UNLESS YOU ARE A QUALIFIED ELECTRICIAN!

WARNING!

As you operate this lift, follow these rules:
