NO OR LOW HYDRAULIC POWER ON INDIVIDUAL FUNCTION.
Hydraulic fluid (Dexron III) is TOXIC. Wear protective goggles and gloves; use only in well-
ventilated area; avoid contact with skin, eyes, and clothes. Skin and clothing that come in contact
with hydraulic oil should be washed immediately. Saturated clothing should be removed
immediately. Failure to comply may result in injury or death to personnel.
Do not check for leaks by hand; oil under hydraulic pressure can penetrate the skin and cause
severe injury. Failure to comply may result in injury or death to personnel.
Step 1.
Check hydraulic cylinder(s) and valve block on problem hydraulic circuit for visible damage or leaks.
If valve block is damaged or leaking, replace or repair valve block (Para 10-15 or 10-16).
If hydraulic cylinder is damaged, replace cylinder (Chapter 10).
If hydraulic cylinder is leaking, repair cylinder (Chapter 10 or Appendix H).
NOTE
Step 2 only applies to the tilt, lift, 4-in-1 bucket cylinders.
Step 2.
Observe operation of tandem hydraulic cylinders on problem hydraulic circuit.
If one side has no power or moves extremely slow, replace or repair damaged cylinder (Chapter 10).
