XLB-4232 DC
3-6
3-2 NORMAL OPERATING PROCEDURE
Perform the following procedures to operate the XLB-4232 DC Boom Lift.
1. Read and follow all safety precautions contained in Section 1 and all
responsibilities 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
electrically 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 slide each outrigger out from the trailer frame.
Slide the outriggers out 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
and all outrigger LED’s are lit.
e. Flip outrigger jack handles over to keep them from being damaged by
falling objects or bent by lowering the boom onto them.
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 boom to the trailer
frame. Stow the transport pin in its storage tube.
7. Unlock and open the base controls door.
8. Toggle the UPPER/OFF/LOWER controls switch to the LOWER position.
9. Use the lower control panel to operate the lift controls. Raise, lower, extend, and
rotate the boom in slow speed to get familiar with the controls. Learn to
smoothly start and stop the boom lift.
10. To place the basket at an easier entry height:
a. Raise the boom clear of its support post by holding the controls selector
switch to LOWER position and also activating the UP function.
b. Rotate the boom clockwise from its transport position by holding the
controls selector switch to LOWER position and also activate CW function.
Rotate until there is clearance between the support post and the boom.
c. Lower the boom until the basket just touches the ground by holding the
controls selector switch to LOWER position and also activate the DOWN
function.
11. Switch the controls selector switch to UPPER controls. Control of the boom is
now directed to the basket control panel.
