Page 9: General Description
GENERAL DESCRIPTION The MLI-1000E maintenance lift is intended for use indoors or outdoors on essentially level concrete floors. It may be used outside in dry conditions and in winds of 20 MPH or less. It's basic dimensions and other data are shown on the drawing near the end of this manual. -

hydraulic movements. MANUAL HYDRAULIC BYPASS A faucet style valve is included in the hydraulic system to allow the platform to be lowered manually. If there is a power failure or other problem while someone is on the platform, someone on the ground can open the bypass valve and lower the platform back down. This valve is located on the frame and is clearly labeled. -

Once the unit is loaded onto the trailer, the wheels should be chocked. Straps or chains should be hooked to the frame near the corners and run to suitable anchor points on the trailer. Do not attempt to use the outriggers or floor lock to prevent movement during transport of the unit. -

MAINTENANCE SECTION GENERAL INFORMATION You are now the proud owner/user of Air Technical Industries’ scissor-type hydraulic-cylinder operated maintenance lift table. The double scissor-type, hydraulic-cylinder operated maintenance lift table, with its many tabletop configurations and options, is a highly versatile machine that is designed to perform a wide range of lifting, transporting, rotating, and moving operations. - Page 13 OPERATING CHARACTERISTICS The hydraulic system, usually contained in the base of the lift, consists of a directly coupled motor- pump combination, oil reservoir, solenoid operated lowering valves, and all necessary plumbing. The hydraulic pump is a positive displacement design, and operates at a usual working pressure of 1200- 1500 PSI.
- Page 14 INSTALLATION SUGGESTIONS PERMANENTLY ANCHORED OR PLACED IN A PIT SEE EXHIBIT 3 Permanent installation of hydraulic lifts may be subject to local codes, rules and regulations, permits and inspection. Check your local and national codes and regulations first. The illustration (EXHIBIT 3) shows the most desirable position of the lift for the greatest stability. The lift can be moved with a lift truck or slings placed around the base frame-caution should be used not to deform the frame or the platform.

- Page 16 BASIC ADJUSTMENT INSTRUCTIONS FOR VELOCITY FUSES NOTE: Do not operate lift to fully raised position while performing the following adjustment. Load lift to desired capacity-raise table to two thirds (2/3) of the raised height. Lower lift-if lowering speed is too fast, the velocity fuses will lock up. If the velocity fuses do lock up, raise the unit to height and adjust lowering valve to limit flow of oil back to reservoir.

Page 17: Trouble Shooting Service Suggestions
We recommend that the lift should be lubricated and completely inspected at least twice a week during the first month of regular operation. Inspection should include a careful examination of all fastenings, fulcrum pins, rolling surfaces and rollers, hydraulic connections, electrical systems, and general functions. - Page 18 B. CHECK OIL LEVEL (WARNING: Do not overfill) With lift in full up position, oil level should be 1 to 2 inches above bottom of the tank. C. CHECK OUTRIGGER INTERLOCKS Verify that both outrigger prox switches are lit up. If one or both are not lit up, make sure that the outriggers are fully extended and in contact with the ground.
