Tip For T650 Model
There is a control lock sensor in the left
console which deactivates the hydraulic
control levers (joysticks) and the traction
drive system when the control console is
raised. The console must be in the locked
down position for the hydraulic control levers
(joysticks) and traction system to operate.
NOTE: If the control lock sensor does not deactivate
the control levers and traction system when
console is raised, see your Bobcat T650 dealer for
service.
