MAINTENANCE
Generally, the AX/AXR/AXS/AXT/AT and AL Series of pneumatic scissor lifts will require little main
-
tenance. However, routine maintenance and inspection will minimize cost of repairs and hazardous
conditions.
WARNING!
Never go under or service lift with a load on the table or with the scissor mechanism
loaded. If possible, service the lift in a down position.
WARNING!
If the pneumatic system requires repairs, shut off and lock out the air supply. Purge the
system of any pressure before beginning any repairs.
