4.4 Throttle Control (pre-2010 models)
See Graphic: wc_gr003876
4.4.1 Adjust the nut (a) on the throttle control lever (b) so that the lever
moves freely but still holds its position while the rammer is operating.
The recommended torque value is 2.9 Nm (2.1 ft.lbs.).
To adjust the throttle cable:
4.4.2 Place the throttle lever in the STOP position (c).
4.4.3 Loosen the clamp screws (d).
4.4.4 Slide the throttle cable (e) through the clamp until there is slack (f) in
the throttle cable and the stop lever activates the stop button (g).
4.4.5 Tighten the clamp screws.
4.4.6 Place the throttle control in the IDLE position (h).
4.4.7 Check that the stop button is not activated. There should be a gap (i)
between the stop lever and the stop button.
4.4.8 Adjust the cable at the clamp as necessary so that the engine stops
when the throttle control is in the STOP position and idles when the
throttle control is in the IDLE position.
