4.12 BOOM CLEANLINESS GUIDELINES
The following are guidelines for internal boom cleanliness
for machines that are used in excessively dirty environ-
ments.
1. JLG recommends the use of the JLG Hostile Envi-
ronment Package if available to keep the internal
portions of a boom cleaner and to help prevent 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 that you follow all guidelines for
servicing your equipment in accordance with the
instructions outlined in the JLG Service & Mainte-
nance Manual for your machine. Periodic mainte-
nance and inspection is vital to the proper operation
of the machine. The frequency of service and main-
tenance must be increased as environment, severity
and frequency of usage requires.
3. Debris and foreign matter inside of the boom can
cause premature failure of components and should
be removed. Methods to remove debris should
always be done using all applicable safety precau-
tions outlined in the JLG Service & Maintenance
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 the debris, then
water with mild solvents applied via a pressure
washer can be used. Again the method is to wash
the debris toward the nearest exiting point from the
boom. Make sure that all debris is removed, that no
“puddling” of water has occurred, and that the
boom internal components are dry prior to operating
the machine. Make sure you comply with all federal
and local laws for disposing of the wash water and
debris.
6. If neither pressurized air nor washing of the boom
dislodges and removes the debris, then disassem-
ble the boom in accordance to the instructions out-
lined in the JLG Service & Maintenance Manual to
remove the debris.
4.13 HOSE ROUTING
For proper hose routing, refer to Figure 4-18., Figure 4-
19., and Figure 4-20. It is important to periodically inspect
hoses, wraps and clamps for proper slack adjustments
and clamping integrity (pull check). Any changes as a
result of inspection should be verified by performing full
strokes of boom functions especially lift, telescope, jib,
and platform rotate.
