anual, have performed the Jobsite Inspection, Pre-Start Inspection and Routine 

Maintenance, and have completed all the test operations detailed in the Operating Instructions

.

Tag and remove a damaged, malfunctioning or modified machine from service. DO NOT use a damaged, 

malfunctioning or modified machine.

Always use the maintenance lock to block the scissor assembly in place before 

servicing the machine with the platform elevated. 

Hydraulic fluid under pressure can penetrate and burn skin, damage eyes, and 

may cause serious injury, blindness, and death. Repair leaks immediately. 

Fluid leaks under pressure may not always be visible. Check for pin hole leaks 

with a piece of cardboard, not your hand. 

Immediately report any damage, defect, unauthorized modification or malfunc

-

tion to your supervisor. Any defect must be repaired prior to continued use. 

DO NOT use a damaged, modified or malfunctioning machine. 

Never leave hydraulic components or hoses open. Plug all hoses and fitting 

immediately after disassembly to protect the system from outside 

contamination (including rain). 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 cause as much damage as no lubrication. 

Watch for makeshift “fixes” which can jeopardize safety as well as lead to 

more costly repair. 

Inspection and maintenance should be performed by qualified personnel 

familiar with the equipment.
