DO NOT operate this machine until you have read and understood the Safety section of this manual, have per-

formed the Jobsite Inspection, Pre-Start Inspection and Routine Maintenance, and have completed all the test 

operations detailed in the Operating Instructions section. 

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

ing 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.

Always use the maintenance lock to block the scissor assembly in place before servic-
ing 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. 

Perform scheduled maintenance at recommended intervals. Failure to perform sched-
uled maintenance at recommended intervals may result in a defective or malfunc-
tioning 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 immedi-
ately after disassembly to protect the system from outside 
contamination (including rain). Never open a hydraulic system when there are contami-
nants 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.
