7.9. RELIEF CARTRIDGE
CAUTION: If your KMW valve is equipped with a relief cartridge, do not tamper with the relief valve
setting. The relief valve is pre-set at the factory. Changing the setting can cause overloading of
the loader and tractor, which may result in serious injury.
7.10. LOAD SENSE LOADER VALVE
IMPORTANT NOTE: If your loader is equipped with a load sense type control valve it may demonstrate the
following operation characteristic. To raise the boom while finely feathering the control lever may allow
the boom to lower very slowly, move the control lever far enough that the boom raises
7.11. INITIAL LOADER OPERATION
Before operating the loader, fully raise and lower the boom two or three times. Then raise the loader bucket
approximately four (4) feet above the ground and cycle the bucket cylinders two or three times. Lower the bucket
or attachment to the ground. Check the tractor hydraulic fluid level and fill as required. Refer to the tractor
Operator Manual for the proper hydraulic fluid and the correct hydraulic fluid level.
CAUTION: When servicing the loader or leaving operator's seat for any reason, always:
Lower the loader to ground.
Turn on Comfort Drive, if equipped
Apply the parking brake securely
Shut off the engine
Turn on tractor switch so Comfort Drive Solenoid is energized.
Release all hydraulic pressure in all circuits by moving hydraulic
control lever or levers in all positions.
Return lever or levers to neutral position.
Turn off tractor switch and remove the key.
IMPORTANT: Always keep the cylinders in a retracted position when the loader is not in use to guard
against rust and contamination which may cause damage to the cylinder rods and hydraulic system.
IMPORTANT: Engage plus handle lever lock in locked position when tractor/loader is being driven on long
distances and the loader does not need to be moved. Always engage this lock when dismounting the
tractor.
7.12. REMOVING AIR FROM HYDRAULIC SYSTEM
Repeat raising and lowering the loader boom and bucket operations until all the air is removed from the system
and the system responds properly.
7.13. RELIEF NOISE
When operating loaders at high RPMs with optional orifice installed in attachment circuit, some hydraulic oil will go
over loader valve relief. This could cause some relief noise from valve, which is normal.
7.14. HOSE IDENTIFICATION
Check if loader functions as shown and described on pages 21 and 22. Then install colored nylon ties, one color
per each circuit. Locate nylon ties so one is attached to male side of quick coupler and one is attached to female
side of quick coupler. This will allow easy identification of loader circuits when mounting and dismounting loader.
