Hazard Identification: Explanation of SIGNAL WORDS

This manual uses SIGNAL WORDS to indicate the likelihood of personal injuries, as well as the probable seriousness of those injuries, if the product is misused in the ways described. Other signal words call attention to uses of the product likely cause property damage.

The signal words used appear below along with the meaning of each word:

Identifies a hazardous situation which, if not avoided, UWILLU result in

DEATH or SERIOUS INJURY. Use of this signal word is limited to

Identifies a hazardous situation which, if not avoided, COULD result

Indicates a hazardous situation which, if not avoided, COULD result

Identifies practices likely to result in product/property damage, such as

Each person who assembles, installs, uses, or maintains this product should read the entire manual in advance

and fully understand the directions. If after reading the manual you do not understand an instruction, ask your supervisor or employer for clarification, because failure to adhere to the directions in this manual might result in serious personal injury.

SAFETY GUIDELINES

Vestil diligently strives to identify foreseeable hazards associated with the use of its products. However, no manual can address every conceivable risk. The end-user ultimately is responsible for exercising sound judgment at all times.

the most extreme situations.

in DEATH or SERIOUS INJURY.

in MINOR or MODERATE injury.

operation that might damage the product.

Electrocution might result if any part of the mezzanine ladder contacts electrified wires. Reduce the

likelihood of electrocution by applying common sense:

 Do NOT assemble or use the cart in an area where it might contact electrified wires;  Do NOT contact electrified wires with the cart;  Before using the crane, always inspect the usage area for conditions that might require special precautions.

If this product is used improperly or carelessly, the operator and/or bystanders might sustain serious personal injuries or even be killed. ALWAYS use the product properly: Material handling is inherently dangerous. Improper or careless operation might result in serious personal injuries sustained by user(s) and/or bystanders. Always apply the following recommendations:  DO NOT attempt to service a loaded cart. Unload the cart and use the maintenance prop BEFORE working on the cart. DO NOT work on the cart unless the maintenance prop is in place.  Keep clear of pinch points! As the deck rises and lowers, pinch points are created. NEVER reach, or put any part of your body, into the scissors mechanism. ALWAYS use the maintenance prop before reaching under the deck. DO NOT put hands or feet under the deck at any time UNLESS the maintenance props are in place.  DO NOT attempt to lift or transport loads that exceed the maximum rated load of the cart. Before transporting a load, secure the load to the deck (if necessary) and then lower the deck.

 DO NOT stand, sit or ride on the cart.  DO NOT use the cart UNLESS all safety labels are in place and readable.  DO NOT use the cart if you hear unusual sounds while raising or lowering the deck.  Always watch the load carefully while raising or lowering the deck.  ONLY use the cart on stable, improved surfaces.  DO NOT leave a loaded cart unattended. ALWAYS unload the cart, and return it to the designated storage location

BEFORE leaving the cart unattended.

 DO NOT modify the cart without the express, written approval from Vestil. Unauthorized modifications could make the cart unsafe to use. Unauthorized modification(s) automatically voids the warranty.  DO NOT modify the ladder in any way UNLESS you first obtain written approval from Vestil. Unauthorized modifications automatically void the limited warranty (see p. 8) and might make the table unsafe to use.

The lifting mechanism of the AIR-2000 series of scissor lift cart will operate both pneumatically (using

factory air) and hydraulically by means of the manually-actuated foot pump. There are 2 swivel casters at

the back of the cart to provide 360 degree range of motion; two fixed casters at the front of the cart provide

stability while the cart travels. In operation, either pressurized air or pressurized hydraulic fluid causes a

cylinder to extend. Cylinder extension in turn causes the scissor leg assemblies to pivot and raise the deck.

OPERATION

This scissor lift cart is suitable for use indoors in most non-classified industrial locations as well as in

many commercial locations. Its intended use is to support and transport stable, evenly-distributed,

non-hazardous materials having dimensions or a footprint approximately equal to or smaller than the

platform.

Loading & Using the Cart:

WARNING: Improper use of this cart could result in serious injuries.

 The platform rollers are not captured, which means that the platform pivots at the end near the handle.

The end of the platform opposite the handle can lift off of the rollers. Therefore, you must NOT position

any load on the platform at the hinged end of the platform because the roller end of the platform might

tip up and dump the load. Always center and evenly distribute the load on the platform. The load should

not overhang the platform, either.

 Keep clear of the scissor/leg mechanisms while raising or lowering the platform.

 Before raising the platform, always engage the caster lock (against the floor).

 The load rating in pounds is shown on a label affixed to the cart. This label indicates the net capacity of

the scissor lift with a static load that is centered and evenly distributed on the platform.

The platform should be fully lowered whenever a load is transported with the cart. Failure to do so

could result in injury to personnel or damage to product or equipment due to the lift and its load becoming

unstable during transport.

- Unit is set up to use the foot pump when received.

- To use the air option, attach an air hose to the air-port & use the hand control to raise or lower the

platform.

- The foot pump can be used even if the air hose is plugged into the unit.

- The foot pump has 2 speeds – if the load is not going up or the foot pedal is hard to move, switch the foot

pump speed selection lever to the lower speed.

Foot Pump Operation

Your new cart is equipped with our exclusive 2-speed foot pump. Features of the pump include: 1)

primary pressure relief valve; 2) pressure compensated return flow control valve; and 3) integrated

lowering valve. Bushings, valve components, and seals are replaceable. Contact the factory for

replacement parts.

Pressing down on the pump pedal causes the platform to rise. Depressing the lowering valve will lower

the table at a constant rate of descent. If the platform is overloaded, the pressure relief valve will open

because of excessive pressure buildup in the hydraulic system. When the pressure relief valve opens, oil will

bypass into the reservoir. NEVER change the pressure relief setting. DO NOT exceed the rated capacity of

your lift equipment.

Speed Selection

This pump offers two "speeds". The “low” speed setting produces low volume/high pressure for fine

adjustments to the platform height. The high speed setting produces high volume/low pressure, which

produces the platform rapidly. The operator has the option of selecting the optimum pump speed for the

application at hand. Pump speeds are selected by sliding the "lock collar" (See below) in or out. An

occasional drop of oil will keep the collar working freely.

Procedure for Bleeding Air from the Hydraulic System

Whether your pump is new or recently serviced, the hydraulic system likely contains air. The design of

this pump includes an "air bleed screw" to facilitate removal of air from the foot pump. To remove air from

the system:

1. Check all fittings to be sure they are tight. Confirm that the oil level is adequate, i.e. within 1" of the

top of the reservoir when the lift is in the fully lowered position.

2. With the platform fully lowered, locate the "air bleed screw". Loosen the screw with an approximately

1/2 turn counterclockwise. As soon as you have loosened the screw, slowly depress the foot pedal to force

air out of the pump chamber. Do not let go of the foot pedal. Tighten the air bleed screw to prevent air from

reentering the pump chamber. Repeat the above procedure until the pump chamber is completely filled

with oil and a "spongy" feel is no longer present when the pedal is pressed. If the air bleeding procedure has

been successful, the feel of the pump pedal will be firm through the entire stroke, i.e. hydraulic fluid will

flow during the entire stroke.
