Additional maintenance inspections are required for the following reasons:
Prolonged storage. Inspect 130G Grader control components that have been stored for a period
of 3 months or longer.
Initial preparation upon receipt.
Preparation for storage.
LEAKAGE CLASSIFICATION AND DEFINITION.
It is necessary for you to know how fluid leakage affects the status of the Blade Pro® Motor Grader Control
System. Following are types/classes of leakage that Operator needs to know to be able to determine the status
of the Blade Pro® Motor Grader Control System. Learn these leakage definitions and remember when in
doubt, notify your supervisor.
· Equipment operation is allowable with minor leakages (Class I or II) with exception of fuel leakage.
Of course, consideration must be given to fluid capacity in the item/system being checked/inspected.
When in doubt, notify your supervisor.
· When operating with Class I and II leaks, continue to check fluid levels as required in your PMCS.
· Any fuel leak or Class III leaks should be reported immediately to your supervisor.
CLASS I Leakage of fluid (as indicated by wetness or discoloration) not great enough to form
CLASS II Leakage of fluid great enough to form drops, but not enough to cause drops to drip
from item being checked/inspected.
CLASS III Leakage of fluid great enough to form drops that fall from item being checked/
Do not start or move Blade Pro® Motor Grader Control System while anyone is under the
130G Grader. Failure to comply could result in severe injury or death to personnel.
Intervals. Intervals (On-condition or hard-time) and related man-hour times are based on normal
operation. Man-hour time specified is time needed to do all services prescribed for a particular interval.
On-condition (OC) oil sample intervals shall be applied unless changed by the Army Oil Analysis
Program (AOAP) laboratory. Change hard-time interval when lubricants are contaminated or when
you are operating equipment under adverse operating conditions, including longer-than-usual
operating hours. Calendar interval will be extended during periods of low activity.
When extended, adequate preservation precautions must be taken. Hard-time intervals will be applied
in the event AOAP laboratory support is not available. Hard-time intervals must be applied during the
warranty period. Intervals shown in this lubrication section are based on calendar and hourly times or
calendar times and mileage. An example of a calendar and hourly lubrication is: M/60 HR, in which M
stands for monthly and 60 HR stands for 60 hours of 130G Grader operation. Lubrication is to be
performed at whichever interval occurs first for the 130G Grader. Special lubrication intervals and
services are shown by the use of an asterisk (*) symbol.
