IMPORTANT: To help keep couplers
clean, always place them in a storage
position when they are not attached to
the tractor.
IMPORTANT: To prevent contaminants
from entering the hydraulic system,
filters must be installed at the tip of a
supply hose. Additional filters are not
recommended as they will restrict oil
flow and adversely affect cylinder
actuation time due to pressure drop.
Without a filter, large dirt particles can enter
the cylinder and settle against the top side of
piston (A) where they can cut the piston seal
as the cylinder retracts.
Replace Hydraulic Hoses
WARNING: Avoid hazards due to
escaping fluid under pressure. See
Hydraulic hoses between the lift cylinders
and hydraulic lock-up valve should be
inspected frequently for leakage, kinking,
cuts, cracks, abrasion, blisters, corrosion,
exposed wire braids, or any other signs of
wear or damage.
Worn or damaged hose assemblies can fail
during use and should be replaced
immediately.
See your Fast Ag Solutions dealer for
replacement hoses.
CAUTION: If an incorrectly rated hose
is used, machine damage, injury, or
death could occur.
If hoses are to be fabricated, ensure that the
hoses are rated at no less than 82,737 kPa
(827 bar) (12,000 psi) burst pressure
according to SAE Standard J517, 100R17
hose specification.
Incorrect hose length or routing can increase
the chance of hose wear or damage. Use the
old hose as a guide for length and hose
routing.
Incorrect fittings can damage mating parts or
cause leaks. Make sure to use steel fittings
approved for use by the hose’s manufacturer.
Use the correct size and thread.
Make sure hydraulic hoses and harnesses
do not interfere with moving parts. Relocate
hoses and harnesses and retain them with
clamps.
Tightening Hardware
Tighten all bolts to torques specified in
otherwise noted.
Check tightness of hardware periodically.
