WARNING
Make sure hydraulic fluid or grease is not injected into skin. Keep hands and body away
from any pressurized leak. Use cardboard or paper to check for leaks. If fluid is injected into
skin, SEEK MEDICAL ATTENTION IMMEDIATELY. Failure to comply may result in serious
injury or death to personnel.
Fuel is flammable and toxic to eyes, skin, and respiratory tract. Avoid contact with eyes, skin,
and clothing. Always wear eye protection and protective gloves when working with fuel.
Avoid repeated/prolonged contact. Use only in ventilated areas. Keep away from open
flames or other sources of ignition. Post FUEL FLAMMABLE/NO SMOKING signs around
area. Make sure fire extinguisher is available. Failure to comply may result in serious injury
or death to personnel.
5. Hoses and fluid lines: Check hoses and fluid lines for wear, damage, and leaks. Check for cuts,
abrasion, or exposed wire braid on hoses. Ensure clamps and fittings are tight.
6. Hinges: Check hinges for security and operation.
7. Data plates: Check data, caution, and warning plates for security and legibility.
8. Cylinders: Check for scoring, pitting, scratches, rust, or other damage.
WARRANTY HARDTIME STATEMENT
For equipment under manufacturer's warranty, hardtime oil service intervals shall be followed. Intervals shall
be shortened if lubricants are known to be contaminated or if operation is under adverse conditions (such as
longer-than-usual operating hours, extended idling periods, extreme dust).
FLUID LEAKAGE
It is necessary for you to know how fluid leakage affects the status of the BHL. The following are
types/classes of leakage you need to know to be able to determine the status of the BHL. Learn these
leakage definitions and remember when in doubt, notify your supervisor.
CAUTION
Equipment operation is allowed with minor leakages (Class I or II), except for fuel which is not
allowed any leakage. Consideration must be given to fluid capacity in the item/system being
checked/inspected. When in doubt, notify your supervisor. Failure to comply may result in
damage to equipment.
When operating with Class I or II leaks, continue to check fluid levels as required in the PMCS.
