GENERAL SAFETY TIPSRegular inspection and conscientious maintenance is the key to efficient economical oper-ation of your aerial work platform. It will help to assure that your equipment will perform satisfactorily with a minimum of service and repair.The actual operating environment of the machine governs the inspection schedule. Cor-rect lubrication is an essential part of the preventative maintenance to minimize wear on working parts and ensure against premature failure. By maintaining correct lubrication, the possibility of mechanical failure and resulting downtime is reduced to a minimum.

• Never leave hydraulic components or hoses open. They must be protected from contamina-tion (including rain) at all times.

• Never open a hydraulic system when there are contaminants in the air.• Always clean the surrounding area before opening hydraulic systems.• Use only recommended lubricants. Improper lubricants or incompatible lubricants may be as

harmful as no lubrication.• Watch for makeshift “fixes” which can jeopardize safety as well as lead to more costly repair.

MAINTENANCE LOCK

DEATH OR SERIOUS INJURY HAZARD!NEVER PERFORM WORK OR INSPECTION ON THE MACHINE WITH THE PLATFORM ELEVATED WITHOUT FIRST BLOCKING THE SCISSOR ASSEMBLY WITH THE MAINTENANCE LOCK.

Figure 1-1: Support Platform

1. Raise the platform approximately 8ft / 2.5m from the ground.

2. Rotate the Maintenance Lock away from the machine and let it hang down.

3. Lower the platform until the Maintenance Lock rests securely on the link. Keep clear of the Maintenance Lock when lowering the platform.

HYDRAULIC SYSTEM

HYDRAULIC FLUID UNDER PRESSURE CAN PENETRATE AND BURN SKIN, DAMAGE EYES, AND MAY CAUSE SERIOUS INJURY, BLINDNESS, AND EVEN DEATH. CORRECT LEAKS IMMEDIATELY.

Hydraulic fluid leaks under pressure may not always be visible. Check for pin hole leaks with a piece of cardboard, not your hand.

ELECTRICAL SYSTEM

Prevent damage to battery and/or electrical system;• Always disconnect the negative battery cable first.• Always connect the positive battery cable first.

When the negative cable is installed, a spark will occur if contact is made between the positive side of the battery and a metal surface on the machine. This can cause damage to the electrical system, battery explosion, and personal injury.

TOTAL SYSTEM

FAILURE TO PERFORM PREVENTIVE MAINTENANCE AT RECOMMENDED INTERVALS MAY RESULT IN THE UNIT BEING OPERATED WITH A DEFECT THAT COULD RESULT IN INJURY OR DEATH OF THE OPERATOR.

IMMEDIATELY REPORT TO YOUR SUPERVISOR ANY DEFECT OR MALFUNCTION. ANY DEFECT SHALL BE REPAIRED PRIOR TO CONTINUED USE OF THE AERIAL WORK PLATFORM.

INSPECTION AND MAINTENANCE SHOULD BE PERFORMED BY QUALIFIED PERSONNEL FAMILIAR WITH THE EQUIPMENT.
