1.The unit is supplied with a power cord which is 10' long. You must provide a two-prong outlet within this distance from the unit. The circuit should be provided with a 20 amp circuit breaker or fuse.

WARNING!

To avoid fire danger, be sure to provide a circuit breaker or fuse.

2.The standard unit has a foot switch assembly. Position the control box in a convenient location near the unit.

3.Check the level of the hydraulic fluid in the tank. In order to check the level, lower the unit completely and unplug the power cord. Remove the rear cover on the unit. When the unit is fully lowered, the oil should be 1/ 2" to 3/4” (13 to 19 mm) below the top of the tank. Add oil as necessary.

Testing

1.Clear the area around the unit. Remove any loose wires, lumber, or other materials which might get in the way of the unit as it raises or lowers.

2.Warn others to stay away from the unit. Operate the unit through its full range of travel. The unit should rise smoothly with a quiet humming sound, and lower smoothly and quietly. Raise and lower the unit a few times to check the lifting action.

WARNING!

As the platform moves up and clown, “pinch points” are created at the places shown in Fig. 2. If you are standing too close to the unit when it is moving, your arm or leg may be caught in the moving parts, and you may be hurt. Stay away from the pinch points when the unit is moving.

3.Test the unit with the rated load. If the unit does not rise, and you hear a loud squealing noise, the pressure relief valve is operating. Contact Presto Lifts for instructions.

WARNING!

Don’t continue to use the unit if this happens - the pump will overheat very quickly, and may be permanently damaged. Do not try to adjust the relief valve. If you change the setting
