DO NOT operate this machine until you have read and understood this manual, have performed the  
Workplace Inspection, Pre-Start Inspection and Routine Maintenance, and have completed all the test  
operations detailed in the Operating Instructions section. 

The operator must conduct a Pre-Start Inspection of the machine and test all functions before each work shift to 
check for damage, malfunction and unauthorized modification. The inspection is designed to discover if anything is 
apparently wrong with a machine before the operator performs the function tests. 
Tag and remove a damaged, malfunctioning or modified machine from service. 

DO NOT

 use a damaged, malfunctioning or modified machine. 

Use the Pre-Start Inspection to determine what Routine Maintenance is required. 

The operator may perform only the routine maintenance items specified in this manual.

IMPORTANT

— Scheduled maintenance inspection checklists are included in this manual for use only by 

 

qualified service technicians. Only qualified service technicians may perform repairs to the machine. After repairs are 
completed, the operator must perform a Pre-Start Inspection before proceeding to the Functions Test.

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.

NEVER perform work or inspection on the machine with the platform  
elevated without first blocking the scissor assembly with the Maintenance 
Lock. 

Perform scheduled maintenance at recommended intervals. Failure to  
perform scheduled maintenance at recommended intervals may result in 
a defective or malfunctioning machine and may result in injury or death of 
the operator. Keep maintenance records current and accurate. Immediately 
report any damage, defect, unauthorized modification or malfunction 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.
