HAZARDS

Vestil Manufacturing strives to identify all foreseeable hazards associated with the use of its products. However,

material handling is dangerous and no manual can address every risk. The end user is ultimately responsible for

exercising sound judgment at all times in the use of this product.

Improper or careless operation of this device might result in serious personal injuries.

Read and understand this entire manual before installing, assembling, using or servicing this lift table. Keep

this manual in a location known to persons who use the lift table. Read the manual whenever necessary to

refresh your understanding of proper use, inspection, and maintenance procedures. Failure to read and

understand this owner’s manual before using or servicing the lift table constitutes a misuse of the product.

The Electric Hydraulic Scissors Lift Table presents pinch point and hydraulic pressure hazards to the user and

bystanders. ALWAYS follow these instructions to avoid injury.

The lift table is intended for use on a level concrete surface. DO NOT use a lift table that has not been anchored

to a level concrete surface. See installation instructions starting on page 14.

Operator’s Manual 2/2/21 EHLT, MANUAL.DOCX

The lift table shall be installed only by trained and qualified personnel with access to appropriate equipment.

Electrical connections shall be performed by a qualified electrician.

DO NOT load the table beyond its lift rated capacity. Handle only stable and safely arranged loads within the

maximum capacity of the lift. The lift capacity can be found on the nameplate on the hinged end of the platform.

ALWAYS use care to center and distribute the load evenly on the lift platform.

DO NOT attempt to lift an overhanging or cantilever load.

DO watch the load when the lift table is in operation.

ALWAYS keep clear of the lift table while it is moving.

DO NOT place hands or feet under the platform. DO NOT put any body part in the scissor mechanism.

DO NOT use this lift table to raise personnel.

DO NOT store objects under the platform.

DO NOT use the lift table if any damage is observed, or unusual noises heard.

DO NOT operate a lift table with its perimeter toe guard removed, disabled, or inoperable. An optional

accordion skirt may be installed in above-ground installations.

DO ensure that all information, safety, and warning labels remain in place and are legible.

DO remove any load from the lift table before servicing the lift table or its hydraulic power unit. DO completely

lower the platform, or use the attached maintenance prop bars to support the platform, before servicing this

product.

If oil is needed, DO use an anti-wear hydraulic oil with a viscosity grade of 150 SUS at 100°F (ISO 32 cSt @ 40°C)

or Dexron non-synthetic transmission fluid. DO NOT use brake fluid or jack oils in the hydraulic system.

Contact the manufacturer for SDS (Safety Data Sheet) information.

Maintenance and repairs are to be done only by personnel qualified to perform the required work.

Consideration will not be given for warranty repair charges without prior written authorization by the

manufacturer.

DO NOT perform any modifications to the lift table without the manufacturer’s approval. Failure to receive

authorization for changes to the equipment automatically voids the warranty.

Proper use and maintenance are essential for this product to function properly.

Always use this product in accordance with the instructions in this manual.

Periodically lubricate pivot points with bearing grease.

Keep the product dry and clean at all times. Always use this product indoors.

Use only factory-approved replacement parts. Contact Vestil Manufacturing to order replacement or spare

parts.

Contact the manufacturer for SDS information.

MODEL NUMBER AND CAPACITY

The lift table model number, serial number and capacities are printed on the nameplate, found on the hinged side of

the platform. Refer to the product catalog of the factory for further information. Include the model and serial numbers

in all correspondence with your dealer or the factory.

The load capacity rating as printed on the nameplate of your lift table designates its net capacity. The addition of

ancillary equipment to the lift table will necessitate a lowering of the load capacity. The lift table’s load capacity must

never be exceeded, as permanent damage or personal injury may result.

ELECTRICAL AND HYDRAULIC SYSTEM DIAGRAMS

Care should be taken to identify all potential hazards and comply with applicable safety procedures

before beginning work. Ensure that all system pressure and electrical power have been removed

before attempting to work on the electrical or hydraulic systems. Follow all applicable lockout/tagout

procedures.

The load must be removed, and the platform either positively and adequately supported or fully

lowered, before any work is performed on the lift table.

Only qualified individuals trained to understand mechanical devices and their associated electrical and hydraulic

circuits, as well as the hazards associated with them, should attempt troubleshooting and repair of this equipment.
