Unrestricted with proper operation, inspection and 
scheduled maintenance.

Important

Read, understand and obey the safety rules and 
operating instructions in the appropriate Operator's 
Manual on your machine before attempting any 
procedure.

This manual provides troubleshooting and repair 
procedures for qualified service professionals. 

Basic mechanical, hydraulic and electrical 
skills are required to perform most procedures. 
However, several procedures require specialized 
skills, tools, lifting equipment and a suitable 
workshop. In these instances, we strongly 
recommend that maintenance and repair be 
performed at an authorized Genie dealer service 
center.
