Lift System
Some assembly of Lift System components is necessary. Follow the steps listed below. See diagram below for the correct hardware
and orientation of parts.
1. Remove all pins and fasteners on each side of the undercarriage and set aside for later installation.
2. Position the lift frame between the two plates on both sides of the undercarriage and align to the bottom holes.
3. Insert pins and hardware to attach the lift frame, the base end of the lift cylinders, and the top arms to the undercarriage.
4. Insert pins and hardware to attach the male quick attaches to the lift frame, and to the top arms. Use 2” washers as shims to
keep top arm pins tight and in place. Only use as many as needed until pin is tight.
5. Torque all fasteners according to the specications on Page 3.

Tractor Side Hydraulics
Note: Refer to Pages 8-9 for the correct hose lengths and hose location.
Note: All connections are identied by spiral bands. 2 bands are from the base end of a cylinder and 1 band is from the
rod end of a cylinder. Orange = Lift, Green = Tilt, Red = Angle, and Yellow = Angle 2-Stick.
1. Connect the lift hoses to the lift cylinders.
2. Verify that hoses are not twisted and protected from rubbing on any sharp edges. See Pages 8-9 for proper hose routing.
3. Install the 45° ttings into the multi-couplers on both top arms.
4. Identify each remaining hose at the front of the undercarriage by the colored bands on the end of the hose and connect the
hose to the corresponding 45° tting on the multi-coupler. Refer to Pages 8-9 for proper hose locations.
5. Continue below for initial startup instructions.
Initial Startup
Prior to operating the blade system, all air must be purged from the hydraulic system. Follow the steps below for each function on
your blade.
Lift Function:
1. With the lift frame down and blocked, loosen the ttings on both ends of the lift cylinders.
2. Actuate the raise function to supply oil to the rod end of the cylinders.
3. When oil starts to ow from the ttings, stop oil ow, and tighten the tting on the rod end of the lift cylinders.
4. Continue to ow oil until the system is fully raised and then block the lift frame.
5. Actuate the function in the opposite direction to supply oil to the base end of the lift cylinders.
6. When all air is removed from the lift system, stop oil ow and tighten the ttings on the base end of the lift cylinders.
7. Raise lift system and remove blocks. Cycle up and down 5 more times.
8. Check tractor oil level and ll if necessary.
9. Continue with connecting the blade on Page 10.
Tilt Function:
1. Use a lift or jack to tilt the blade system until the left side is fully up, loosen the ttings on the rod and base end of both tilt cylinders.
2. Actuate the tilt function to extend the right tilt cylinder and supply oil to the base end of the right cylinder and to the rod end of the
left cylinder.
3. When oil starts to ow from the ttings, stop oil ow, and tighten the tting on the base end of the right cylinder and rod end of
the left cylinder.
4. Remove the lift or jack.
5. Continue to actuate the tilt function until oil ows out of the remaining open ports.
6. Actuate the tilt function in the opposite direction.
7. When all air is removed from the tilt system, stop oil ow, and tighten the remaining ttings on the cylinders.
8. Cycle both cylinders in and out 5 more times.
9. Check tractor oil level and ll if necessary.
Run the blade through all the functions. If any function does not operate correctly, refer to corresponding section above and re-
bleed. If problem still persists, call Grouser Products.

Hydraulic Multi-Coupler Maintenance
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.
