From the Platform Control Station:
1. Check that the control console is secure and all guards pro-
tecting the function switches or locks are in place. Ensure
that all function controls and switches return to the "off" or
neutral position when released.
DO NOT OPERATE MACHINE IF GUARDS OR LOCKS ARE MISSING OR THE SWITCHES DO
NOT RETURN TO THE "OFF" OR NEUTRAL POSITION
2. Check the footswitch adjustment and operation as follows:
a. With engine power shut down, attempt to start engine.
Engine should not attempt to start when footswitch is
activated.
b. Start engine. Activate hydraulic system by depressing
footswitch. Activate a boom function. Continue to acti-
vate the function and remove foot from footswitch. The
motion should stop.
DISCONTINUE OPERATION IF THE FOOTSWITCH DOES NOT OPERATE PROPERLY.
c. Check adjustment of footswitch. Footswitch must be
adjusted so that functions will operate when pedal is
approximately at its center of travel. If the footswitch
operates within last 1/4" of travel, top or bottom, it
should be adjusted.
NOTE: Footswitch has a 7 second delay timer. If a function is not acti-
vated within 7 seconds after depressing the footswitch, reset the
footswitch.
3. Ensure that all machine functions are disabled when the
Emergency Stop Button is activated.
4. Check auxiliary power for proper operation. Operate each
function control switch to ensure proper operation of the
auxiliary power system.
NOTE: Step 5 is only applicable for 740AJ ANSI market machines.

switch as follows:
a. On a level surface with less than 500 lb (227 kg) in the
platform, raise tower base boom to maximum angle
keeping main boom horizontal.
b. Extend the main fly boom until the capacity indicator
lights change from 1000 lb. (454 kg) to 500 lb. (227 kg).
c. With main boom in this position, raise the main base
boom until the capacity indicator lights change back to
the 1000 lb. (454 kg) indicator.
