• Inspect all bolts, and tighten any loose bolts to torque specications on page 3.
• Check replaceable cutting edge for wear ensuring there is enough material to prevent permanent damage to the blade.
• Check hydraulic cylinders and hoses for damage or leaks. For replacement parts, see hydraulic pages for your specic
system.
• If equipped with hydraulic multi-coupler, see page 16-18 for hydraulic multi-coupler maintenance.
• Make sure all non-rotating pins are secured properly.
• Inspect all decals and order replacement decals from your dealer if any are damaged or worn.

Cleaning The Male Interface Seal:
1. Make sure the coupling is securely
fastened into the plate or place in
a vice.
2. Using a blunt, non-marring tool,
depress the valve face until the seal
is exposed. Insert a bent metal
wire between the valve face and the
body of the coupling. Use caution
not to damage or scratch the seal
when inserting the wire.
3. Inspect the seal and interior
surfaces for contamination.
4. In case of contamination, carefully
wipe surfaces with a soft cloth, or
use compressed air to blow the
contamination out. Do Not press
hard on the seal as contamination
can scratch the seal surface.
5. Using a non-marring tool, depress
the valve face and remove the metal
wire. Release the valve to the ush
position.
Cleaning The Female Bushing:
1. Make sure the coupling is securely
fastened into the plate or place in
a vice.
2. Using a non-marring tool, depress
the outer ring to expose the
bushing. There is no need to
expose the valve seal, so stop
pressing before the valve is opened.
3. Inspect the interior body and
bushing surfaces for contamination.
4. In case of contamination, carefully
wipe surfaces with a soft cloth, or
use compressed air to blow the
contamination out.
5. Release the outer ring so that it
returns to the ush position.
