4. Check that the circuit is open with the multi-
meter.
5. Rotate the turret around the base past 90° and
stop. Verify machine directions continue to
operate as the controls indicate.
WARNING
The drive orientation can change when the turret is
swung 90 degrees off center of the normal driving
position (roughly when boom is swung past the
rear tire). Drive re-orientation does not occur while
driving and rotating until the joystick is released
for 6 seconds or when the footswitch is released.
6. Verify the circuit is now closed with the multi-
meter. Continuity is indicated when the turret
is rotated past 90°. Check both clockwise and
counterclockwise directions.

5.4-23 High Speed Drive / Tilt Override
LS2 detects when the boom is raised above
horizontal. The machine drives at normal speed with
the boom fully lowered, but is limited to a slow drive
speed of 0.5 mph (0.8 km/h) when the boom is raised.
LS2 is normally closed. It opens when it contacts a
cam on the turret frame when the boom is raised up
past horizontal. The switch roller contacts the cam and
the system switches from normal to slow drive speed.
LS2 is the upper switch located on the rear, left-hand
side of the turret frame.

NOTE
Make sure the switch roller rotates freely and the
switch arm is free to move as the boom raises
and lowers.
