4.3 BOOM CLEANLINESS GUIDELINES
Following are guidelines for machines used in excessively dirty
environments.
1. JLG recommends use of JLG Hostile Environment Pack-
age to keep internal portions of a boom cleaner and pre-
vent dirt and debris from entering the boom. This
package reduces the amount of contamination which
can enter the boom but does not eliminate the need for
more frequent inspections and maintenance when used
in these types of environments.
2. JLG recommends you follow all guidelines for servicing
your equipment in accordance with instructions out-
lined in the JLG Service & Maintenance Manual for your
machine. Periodic maintenance and inspection is vital to
the proper operation of the machine. Frequency of ser-
vice and maintenance must be increased as environ-
ment, severity, and frequency of usage requires.
3. Debris and foreign matter inside boom can cause pre-
mature failure of components and should be removed.
Methods to remove debris should always be done using
all applicable safety precautions outlined in the JLG
Operation & Safety Manual and the JLG Service & Main-
tenance Manuals.
4. The first attempt to remove debris from inside the boom
must be to utilize pressurized air to blow the debris
toward the nearest exiting point from the boom. Make
sure that all debris is removed before operating the
machine.
5. If pressurized air cannot dislodge debris, apply water
and mild solvents with a pressure washer. Wash debris
toward nearest exit point from the boom. Make sure all
debris is removed, no “puddling” of water has occurred,
and boom internal components are dry before operat-
ing machine. Comply with all federal and local laws for
disposing of wash water and debris.
6. If pressurized air or washing dislodges and removes
debris, disassemble boom in accordance with instruc-
tions outlined in the JLG Service & Maintenance Manual
to remove the debris.
