MOUNTING INSTRUCTIONS
Oil Grade Selection
Use the proper oil grade for the weather conditions
anticipated during operation.
Cold: -20°F to 40°F (-29°C to 4°C)
Use ISO 32 (10W) or less hydraulic fluid (full synthetic
strongly recommended). Alternate: 10W-30 motor oil
or ATF.
Automotive type crankcase oils with American
Petroleum Institute (API) letter designations SE, SF,
SG, SH or higher (per SAE J183) classes of oils are
acceptable. These types of oils generally exhibit less
shear stability, which can result in higher loss of
viscosity during service life.
IMPORTANT: In cold weather, always preheat the oil
using the supplied 1000W oil heater to prevent pump
cavitation. Run the PTO pump at low speed for at
least 15 minutes to warm the system up to at least
50°F before operating under load.
Warm: 40°F to 100°F (4°C to 38°C)
Use ISO 32 (10W) or greater.
NOTE: See page 25 for oil viscosity information.
5. Route the cooler fan wire harness to the tractor
battery. Connect the red (fused) wire to the
positive (+) terminal of the battery and the black
wire to the negative (-) terminal of the battery.
IMPORTANT: Make sure the fuse is operational
and rated for a minimum of 40 amps.
6. Connect the rear set of hydraulic quick couplers to
the lead hoses, and the cooler fan wire harness to
the cooler fan connector.
IMPORTANT: Make sure the quick couplers are
fully engaged. If couplers will not engage, do not
force quick couplers together.
NOTE: Attachment is shipped with 16FJX
(1-
5/16” Female JIC Swivel) fittings on the ends of
the lead hoses.
7. Check all fittings to make sure they are tight.
8. Fill the tank with the correct grade of NEW
hydraulic oil (or other approved fluid) until the oil
level is centered in the sight gauge on the left side
of the tank. The tank capacity is 33 gallons (125
L), but up to an additional 3 gallons (11.4 L) may
be needed to fill the hoses and attachment.
9. Connect the two lead hoses together at the front
of the loader and test run the pump at low speed
to check for leaks and to flush the system.
IMPORTANT: Do not flush the system with the
lead hoses connected to an attachment or
contamination may become lodged in the
attachment system.
10. Run the system at full throttle for at least 15
minutes to flush the system of any possible
contamination.
IMPORTANT: Always engage the PTO drive with
the engine at low speed. This is especially
important during cold weather start-ups.
11. Mounting is now complete and the PTO pump is
ready for operation.
