4.10. REMOVING AIR FROM HYDRAULIC SYSTEM
Repeat raising and lowering the loader boom and bucket until all the air is removed from the system and the
system responds properly.
Check the tractor hydraulic fluid level and fill, if required.
NOTE: Your loader lift and attachment circuits will have some leak down. This drift down is normal and is
caused by loader valve spool leakage. Always position loader on the ground when not in use and be alert
while transporting large loads a long distance. To check for acceptable leak down, see section 18. Leak
Down Inspection. This test must be run and leak down must be above these rates before any warranty is
applied for.
NOTE: Always change hydraulic oil in tractor as specified in tractor manual. Contaminants in hydraulic
system will cause damage to loader valve spools, increasing leakage rate which is not covered under
warranty.
NOTE: Use only recommended hydraulic oil as specified in tractor operators manual. Failure to follow
these instructions could cause damage to loader hydraulic components and can increase loader leak
down rate.
