Page 14: Passing And Protecting Cables
You should always leave some leeway for the cables. When giving full-lock steering to the left and right, the cables should not become too tight or too slack. Figure 1-21. Proper Amount of Slack in Cables WLS-C Wheel Loader Scale... - Page 15 Do not mount the cables too close to the motor, unless they are well insulated. If you use clips to fix the cables down, remember not to tighten them too much. Very often, cable breakage is due to over-tightened clips. Figure 1-23.
