WARNING! Never go under or service lift with a load on the table or with the scissor mechanism unblocked. Always service the lift in a down position.

All servicing should be done by qualified personnel. Qualified personnel should be able to read and understand wiring and hydraulic diagrams.

DANGER! The lift may use a power supply of up to 575 Volts AC. This voltage can kill. Do not work with the electrical parts unless you are a qualified electrician!

WARNING! As the lift moves up and down, 'pinch points' are formed. Keep hands, feet, and loose clothing away from these pinch points.

WARNING! A falling lift can cause severe personal injury. Before working under the lift remove any load from the platform, raise the lift and insert the maintenance devices.

WARNING! Release of fluids under high pressure can cause personal injury. Before you open any part of the hydraulic system, be sure to release the hydraulic pressure.

CAUTION! The warning labels on the lift are there for the safety of the operators. If the labels are worn or missing, or have been painted over, replace them before releasing the lift for operation.

WARNING! If you are going to repair the center pivot pins and bushings, you must support the lift table in a special way.

NOTICE It is important to use hydraulic fluid with the correct grade and properties.

NOTE: If lubrication points will not take grease, ensure that the load has been removed from the platform, and ensure the grease fittings are not plugged and will take grease, or the weight of the lift may need to be removed from the greaseable joint.

A fork truck or overhead crane may be necessary to remove any weight off of the greaseable joints. Contact Presto/ECOA Service Department for further instructions if the machine is still unable to accept grease.
