    JLG 40E stuck in slow motion mode

    Art, Can you try this to see if you have the same issue on your lift. From the platform, press the steering either left or right, doesn't matter which. The while holding the left or right steering press the boom function that was running slowly. Does your unit "kick" into fast mode by moving...

    JLG 40E stuck in slow motion mode

    JLG 40E stuck in slow motion mode

    hey Art, I still have the same issues with mine. I have all new batteries, drive motors were rebuilt and still is slow motion. I may replace the motor controller but thats $$$$ and I can't figure anything else as I've checked all wiring and fuses and such.

    JLG 40E stuck in slow motion mode

    could the proportional relief valve cause the lift to operate in slow motion mode? When activating the steer function it "kicks" into normal operation. Thinking outloud to get this thing fixed to cut hurricane trees down on the property.

    JLG 40E stuck in slow motion mode

    Rick, Fully charged and tried all above procedures. Still no go. Any idea how to get the drive motors to function? Looks like the booms will not speed up and may take to repair facility. Just cant figure this out...... Can we try and tackle the drive motors. Moving the joystick I get nothing...
