A pre-operation inspection is a visual inspection of a mobile elevating work platform (MEWP) performed by the operator prior to each work shift. The inspection is designed to discover if anything is apparently wrong with a machine before it is put into service
A best practice for safe work at height is for the MEWP operator to follow the step-by-step instructions listed in the manufacturer’s supplied operator’s manual to complete the pre-operation inspection prior to start-up of each shift. For example, Genie operator’s manuals contain specific, detailed instructions on what tasks to perform, as well as how to perform the tasks.
Below is an example of a pre-operation inspection check list that Genie recommends its MEWP operators perform:
Be sure that the operator’s and safety manuals are complete, legible and in the storage container located in the platform.
Be sure that all decals are legible and in place. See the “Inspections” section of the operator’s manual for guidance.
Check for hydraulic oil leaks and proper oil level. Add oil if needed. See the “Maintenance” section of the operator’s manual for guidance.
Check for battery/engine fluid/oil leaks and proper fluid level. See the “Maintenance” section of the operator’s manual for guidance.
Check for engine coolant leaks and proper level of coolant. Add coolant if needed. See the “Maintenance” section of the operator’s manual for guidance.
Check the following components or areas for damage, improperly installed or missing parts and unauthorized modifications:
Electrical components, wiring and electrical cables
Hydraulic hoses, fittings, cylinders and manifolds
Fuel and hydraulic tanks
Drive motors/turntable motors and drive hubs
Tires and wheels
Engine and related components
Battery pack and connections
Limit switches, alarms and horn
Alarms, beacons, and lights (if equipped)
Pins, nuts, bolts and other fasteners
Brake release components
Safety arm (Genie® GS™ Scissor Lifts)
Scissor pins and retaining fastener
Platform control joystick
Outrigger housing and footpads (if equipped)
Ground strap (All Genie® electric MEWPs)
Platform entry mid-rail or gate
Platform extension (Genie® GS™ Scissor Lifts and GR™ Runabouts)
Platform overload components
Pothole guards (Genie®GS™ Scissor Lifts and GR™Runabouts)
Lanyard anchorage points
Check entire machine for:
Cracks in welds or structural components
Dents or damage to machine
Excessive rust, corrosion or oxidation
Be sure that all structural and other critical components are present and all associated fasteners and pins are in place and properly tightened.
Be sure side rails are installed and bolts are fastened (Genie® GS™ Scissor Lifts)
Be sure that the chassis trays are closed and latched and the batteries are properly connected. (Genie® GS™ Scissor Lifts)
After you complete your inspection, be sure that all guards, screens and compartment covers are in place and latched
Operators should always read the MEWP’s operator’s manual, provided by the equipment manufacturer, to learn more on how to perform these tests. It is important that operators always use the appropriate operator’s manual for the MEWP they are inspecting.
