3-2 NORMAL OPERATING PROCEDURE
Perform the following procedures to operate the XLB-4725A Boom Lift.
1. Read and follow all safety precautions contained in Section 1 and all responsi-
bilities outlined in the ANSI A92.2 reprint contained in Section 7 of this manual.
2. Position the lift at the work area. Make sure the lift is on a firm and level surface
and that there are no potential hazards such as overhead obstructions or electri-
cally charged conductors. Do not operate the lift if such hazards exist.
3. Check the tow trailer and boom lift for damaged or worn parts. Repair or replace
parts as necessary. Do not use a damaged boom lift.
4. Lower the trailer tongue jack and unhitch the trailer from the tow vehicle. The
trailer must be unhitched before the outriggers are deployed.
5. Deploy the boom lift outriggers as follows:
a. Lift up on the locking pin and pull each outrigger away from the trailer
frame. Swing the outriggers away until the locking pins engage again.
b. Pull out the quick-adjust jack pins and lower the jack feet. With the jack feet
near the ground, reinstall the jack pins at the lowest available setting.
c. Turn the BATTERY ON/OFF switch to the ON position. Lift the bubble
level cover plate in front of the boom rotation housing (slew ring housing).
d. Jack up the outriggers to evenly raise the trailer; refer to the bubble level.
Raise the boom lift evenly until at least one trailer wheel is off the ground.
NOTE: An axle position switch will prevent boom operation if at least one wheel
is not lifted off the ground. The load of the boom lift must be placed on
the outriggers to enable power.
6. Remove the pin keeper and transport pin that secures the lower boom to the
trailer frame. Stow the transport pin in its storage tube.
7. Turn the PLATFORM/OFF/GROUND key switch to the GROUND position.
CAUTION
Do not crank the engine for more than 15 seconds at a time. Extended engine
cranking may overheat and damage the starter motor.
8. (Gas Model Only) Toggle the ENGINE START switch to start the engine. If
the engine is cold, hold the CHOKE switch down for about five seconds while
cranking. Allow the engine to idle for at least five minutes before operating the
boom lift hydraulics.
9. Use the lower control panel to operate the lift controls. Raise, lower, and rotate
the boom to get familiar with the controls. Learn to smoothly start and stop the
boom lift.
10. With the upper boom fully down, raise the lower boom to upper limit to position
the basket for boarding. Turn the key switch to the PLATFORM position.
11. Raise the safety bar and enter the basket. Put on the safety harness and attach the
lanyard to the basket railing. Operate the boom lift carefully.
