11. Continue to actuate the right angle function in the same direction until the cylinder is fully extended.
12. Actuate the right angle function in the opposite direction.
13. When oil starts to ow from the rod end tting, stop oil ow, and tighten the rod end tting on the right angle cylinder.
14. Continue to actuate the right angle function until cylinder is fully retracted.
15. Cycle the left cylinder in and out 5 more times and then the right cylinder in and out 5 more times.
16. 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.

CORRECT CORRECT
(Left or Right)
When either angle cylinder reaches the end of its stroke and the safety relief valve reroutes pressure to the opposite cylinder
causing it to extend, adjust the relief valve. To set the electric safety relief valve at a higher pressure than tractor: Use a pressure
gauge connected between the tractor pump and the port A on the electric relief valve on the blade to check the tractor pressure and
record the reading. To increase the pressure of the relief valve, install a 0-5,000 psi pressure gauge between the hose and tting
in the base end of right angle cylinder. Make sure both angle cylinders are retracted. Loosen the jam nut on the valve system relief
cartridge. Next, start tractor and extend the right side cylinder out until the safety valve activates, while the safety valve is in function
(pressure being rerouted to opposite cylinder causing opposite cylinder to extend), record the pressure reading on the gauge.
Tighten the Allen screw in small increments and record the pressure until the pressure is about 50-100 psi higher than the tractor
pressure. Do not exceed the 3,500-psi operating pressure of the cylinders. Tighten the jam nut and remove the gauge.
CAUTION: Do not bypass the safety relief valve and plumb each cylinder to separate valves on the tractor.
Hydraulic Angle System Operation Relief Valve Adjustment

With the Electric Hydraulic Angle Option, you will have the ability to angle the blade 30 degrees left or right. To achieve these
angles, the two cylinders are designed to operate independently of each other through an electric diverter valve. To angle the blade
to the left, actuate the tractor hydraulic control lever in the cab with the diverter valve un-powered. To angle the blade to the right,
apply power to the diverter valve and then actuate the tractor hydraulic control lever.
The safety relief valve allows the cylinder to retract if its internal pressure becomes excessive. With this safety feature in place,
when either cylinder reaches the end of its stroke, the safety relief valve will reroute pressure to the opposite cylinder causing it to
extend. If this occurs, refer to the Relief Valve adjustment below for possible adjustments. Only one cylinder should be extended
when angled dozing.
With the 2-Stick Hydraulic Angle Option, you will have the ability to angle the blade 30 degrees left or right. To achieve these
angles, the two cylinders are designed to operate independently of each other with the use of 2 tractor hydraulic control levers and
a safety relief valve. To angle the blade to the left or right, actuate the tractor hydraulic control lever corresponding to the left or
right cylinder.
To ensure proper use and life of equipment, it is recommended to have both cylinders closed for straight ahead dozing and only
one cylinder partially or fully extended for angled dozing as shown in the diagrams below. If the angle system is not used correctly,
frame damage may occur. Diagrams below may look slightly different than your system, but the information is still compatible and
important to your system.

To Connect:
Note: If necessary, use a spotter to help center the blade on the lift system.
1. Before standing blade upright for initial connection, remove the 3/4” pin (#20 on Page 12) so the skid shoes can move freely.
The blade will lean back further for easier connection. Store the pin in the storage location (See Page 11 for location).
2. If necessary, lift the locking latch and pull the quick attach lock handle on the left side of the lift system to open the quick
attach system. Refer to Page #14-15 for further clarication on the quick attach system.
3. Drive the tractor forward slowly until the top edge of the male quick attach is under the top hook of the female quick attach on
the blade assembly.
4. Raise the lift system until the male quick attach engages the female hook. If both sides don’t fully engage, reposition.
Continue to raise the lift system until the blade is off the ground and the female quick attaches are against the front of the male
quick attaches.
5. Shut off the tractor engine and set the parking brake.
6. Push the quick attach lock handle to engage the quick attach pins and lift the locking latch to lock the handle in place.
7. Clean and connect hydraulic multi-coupler on the top arm. Refer to Pages 18-19 for cleaning and connecting information.
8. If applicable, plug the male blade break away end of the wire harness into the female blade break away end of the wire
harness on the top arm.
9. Lock the mushroom skid shoe link back in place with the 3/4” pin you removed in Step #1.
10. If initial startup, refer to Page 8 before operating any function of the blade.
To Disconnect:
1. Lower the blade until the cutting edge is off the ground a few inches.
2. Shut off the tractor engine and set the parking brake.
3. Unhook the multi-coupler on the top arm.
4. Remove the multi-coupler cover from the parking station on the blade assembly and install on the multi-coupler on the top arm.
5. Plug the blade side multi-coupler into the parking station.
6. Lift the locking latch and pull the quick attach lock handle to disengage the quick attach pins.
7. Remove the 3/4” pin so the skid shoes can move freely and the blade can lean back. Store the pin.
8. Start tractor, disengage the parking brake, and lower the blade until cutting edge is on the ground.
9. Continue to slowly lower the lift system to disengage the blade.
10. Slowly back away from the blade. When lift system is clear from the blade, raise the lift system.
11. Shut off the tractor engine and set the parking brake.

Skid Shoe Adjustment
Preferred Method:
1. The preferred blade position for adjusting the tilt plates is laying face down on blocks.
2. Remove the 6 bolts from the right tilt plates.
3. Add or remove washers as needed to adjust tilt-way clearance to 1/16” - 1/8”.
4. Reinstall the bolts in the right tilt plates.
5. Follow Steps #2-4 for the left tilt plates.
6. Once the tilt-way clearance is set, torque bolts to 640 ft-lbs.
Non-Preferred Method:
Note: Do not remove all of the bolts at the same time if the blade is not laying face down.
1. The non-preferred blade position for adjusting the tilt plates is
the blade in the upright position.
2. Remove the 3 bolts from the top right tilt plate and the
bottom left tilt plate..
3. Add or remove washers as needed to adjust tilt-way
clearance to 1/16” - 1/8”.
4. Reinstall the bolts in the top right tilt plate and the
bottom left tilt plate.
5. Follow Steps #2-4 for the bottom right tilt plate and
the top left tilt plate.
6. Once the tilt-way clearance is set, torque bolts to
640 ft-lbs.

Skid Shoe Adjustment:
1. Remove the handle from the ratchet keeper by pulling the
hitch clip pin and insert it into the handle receiver on the
ratchet jack.
2. Loosen the locking nut on the ratchet jack.
3. Hold the body of the ratchet jack and rotate the ratchet jack
handle to raise or lower the skid shoes.
4. If the skid shoe is not moving in the proper direction, ip
the forward/reverse lever on the handle (see Figure 2).
Rotate the ratchet jack handle again to move the skid
shoe in the desired direction.
5. After the skid shoe is adjusted, rotate the ratchet jack
handle until it rests against the ratchet keeper. Return the
removable handle to the ratchet keeper ensuring that the
ratchet jack handle is captured by the removable handle
and the ratchet keeper. Secure the handle to the ratchet
keeper with the hitch clip pin.
6. Tighten the locking nut against the ratchet jack body to
keep it from moving.
7. When skid shoes are worn up to the bolt heads, replace
skid shoes.

Note 1:
When sand and salt are present, or the plates under go a washdown,
a heavy duty silicone spray lubricant should be used to replace
grease from the factory. The lubricant should help protect from
corrosion without collecting dust and contaminants, and will resist
washing off when exposed to water.
Recommended Lubricant Brands:
Fluid Film (Aerosol or Non-Aerosol), LPS-2 Heavy Duty Lubricant, or
CRC 3-36.

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.
