HIGH SPEED CONTROL
A "High-Speed" switch is located on or adjacent to the pump panel. This switch increases the
engine speed and hydraulic pressure at the same time. The speed of any operation of the
tower can be increased with this switch. CAUTION MUST BE TAKEN WHEN USING THIS "HIGH-
SPEED" SWITCH.
Before engaging the "High-Speed" switch, the operations control lever must be
in position. When coming off "High-Speed", release the switch, then release the
control lever to complete movement. This will give a smooth and safe operation.
When extending the tower and using the "High-Speed" control, release the "High-
Speed" switch before reaching maximum extension. Tower extension will stop at
maximum extension of the tower. (There is no signal device for indicating full
extension.)
When retracting the tower and using the "High-Speed" switch, the same
procedure applies to the use of the "High-Speed" control. Make sure to release
the "High-Speed" switch before reaching full retracted position.
The tower can rotate a continuous 360 degrees to the left or right. Use the "High-
Speed" switch, if it is necessary to rotate the tower at a faster speed.
The rotation control lever must be engaged before engaging the "High-Speed"
switch. When coming off "High-Speed", release the "High-Speed" switch before
releasing the rotational control lever. This will give a smooth operation. WHILE
ROTATING THE TOWER, THE OPERATOR SHOULD NOT CHANGE DIRECTIONS
BEFORE THE TOWER COMES TO A COMPLETE STOP! If the operator accidentally
changes rotation direction with the tower not coming to a complete stop, a built-
in relief valve is provided to reduce the shock. However, in no way should this be
an operational practice!
