JOYSTICK 7 SECOND ENABLE

09/05/2014

The joystick controllers used on the Skyjack SJIII Compact and Conventional scissor lifts, the SJ12/16 Mast lifts, and the Rough Terrain scissor lifts have incorporated a change to the enable circuit of the joystick. You may notice this change when you are troubleshooting the machine. Once the enable trigger is squeezed, an internal timer starts running; if a function is not operated within 7 seconds, the enable circuit is shut off and the joystick trigger must be released and depressed again to reset the enable circuit. The 7 second cut-out is used to inhibit tampering with or bypassing the enable switch with tape, a zip tie, or other means.

To avoid the 7 second cut-out while trying to diagnose or troubleshoot the machine function, always make sure that the joystick enable is not held on continuously.

You can identify the joystick with the 7 second cut-out by checking for the cut-out function or by the part number (see table below).

MODEL PART NUMBER
SJIII Compact & Conventional Scissor lifts 159108
SJ 12 & SJ16 Mast lifts 159111
Compact, Mid-size, & Full-size Rough Terrain lifts 159109

The part number will be on the side of the joystick frame inside the control box. These joysticks with this functionality have been used in production since March 2012, and sold by Skyjack parts department since August 2012.

When troubleshooting a no or low voltage output problem on a generator, make sure the generator to pump coupling is tight. Generator rpm is essential to correct generator voltage output. 
Both the gen and pump shafts may appear to be turning at the same speed, but the generator may be spinning slower due to the coupler being loose at either shaft.
