Filter buggies or carts are commercially
available for hydraulic system clean-up.
These consist of a high-efficiency, high-
capacity filter, a circulating pump, a drive
motor, and hoses for connecting the
overhauled machine’s hydraulic system.
ASM-FL-0048
After the first 10 hours of operation, replace
the hydraulic filter with a new one. An extra
Filter Element is provided for you. Refer to
the Operation and Maintenance Section for
instruction.
7. After the Interstater mower is completely
assembled to the tractor and with the wings
on the ground, fill the mower hydraulic tank
above the oil level sight gauge approximately 5" or 1" below the top of the tank.
8. With mower ON/OFF switches in “ON” position and tractor fuel cut off, crank engine for about 30 to 45
seconds to allow oil to fill pumps and motors. Check the oil level in the sight gauge. If no oil is seen add oil to
bring the level up to the sight gauge. NOTE: Do not fill the tank with oil above the level of the sight gauge.
Over filling the tank with oil af ter the initial filling may result in oil being discharged through the air filter on top of
the hydraulic tank. Start the tractor and run it for 2 minutes and then turn it off. Again check the oil level in the
sight gauge. If the oil level is in the sight gauge, the unit is ready to run. If no oil is seen, add oil to bring the
level up to the sight gauge.
Remove all foreign objects and stand clear of cutter units. DO NOT GET NEAR ROTATING
KNIVES!
NOTE: On tractor hydraulic powered circuit only, make certain that there is full flow from tractor hydraulic
system to control valve. Refer to tractor manual.
9. After hydr aulic system is fully charged and functio ning proper ly, switch cutter unit s on , then speed engine up
to 540 RPM PTO speed. Maintain this speed for about 5 minutes. Check complete INTERSTATER, look for
any leaks, loose connections, or anything that could cause premature wear or failure.

FINAL CHECK

Run INTERSTATER for about 1/2 hour at full speed. Check for leaks and vibrations. Frequently check oil
temperature. Make certain it does not exceed 180 deg.
NOTE: When raising wings, make certain there is no interference with mower, frame, cylinders or tractor. Lift
wings slowly.
DO NOT leave unit unattended, and COMPLY WITH ALL WARNING DECALS.
If unit start s to make unusu al noise, stop unit and check oil level. Also check for frothy oil which would indicate
a leak on suction side of system.
