Swing Deceleration Force Test
With the boom, arm and bucket in the same position as for the
swing speed test, rotate the turntable so that the boom is evenly
centered between the side frames, pointing straight ahead.
Locate the 90° reference point, perpendicular to the boom. Mark
the turntable and undercarriage with paint at the 90° point.
Make several attempts to rotate the turntable exactly 90°,
starting from the boom straight ahead position. Engage the
swing lever and brake at the 90° point, shown as "swing stop" in
Figure 7.
Record how far the turntable drifts past the stop point,
measuring the distance between paint marks. Maximum
distance should be less than 1200 mm (47-1/4"), in both Power
Mode and Standard Mode.
