8. MAIN FRAME DOES NOT OPERATE (CONT).
WARNING
·
The LHS hydraulic system operates at oil pressures up to 1,725 psi (11 894 kPa).
Never disconnect any hydraulic line or fitting without first dropping pressure to
zero. Failure to comply may result in serious injury or death to personnel.
·
Fuel and oil are slippery and can cause falls. To avoid injury, wipe up spilled fuel or
oil with rags.
·
Compressed air used for cleaning purposes will not exceed 30 psi (207 kPa). Use
only with effective chip guard and personal protective equipment (goggles/shield,
gloves, etc.). Failure to comply may result in injury or death to personnel.
NOTE
Hose 2917 is disconnected while installing and removing pressure gage. Hose 2917 must be
connected during test.
Step 2. Check velocity fuses in both LH and RH main frame cylinder manifolds.
If air cannot be blown through velocity fuse, replace velocity fuse (Para 5-39).
