Tools

Parts

Step 1

Flip the red engine ON/OFF switch to the ON position.

Step 2

Follow the device's detailed operating and safety procedures before starting the device.
Pull the motor's pull-start cable to start the motor.

Step 3

Push the control valve lever towards the rear of the device to extend the piston and advance the cutting wedge.

Step 4

Flip the red engine ON/OFF switch to the OFF position.

Step 5

Use an impact wrench with a 3/4 inch socket to loosen the twelve bolts and twelve nuts securing the slide bars to the underside of the cutting wedge.
If an impact wrench struggles to remove these bolts, a breaker bar may be necessary.

Step 6

Remove the left slide bar.

Step 7

Remove the right slide bar.

Step 8

Remove all twelve 3/4 inch bolts from the cutting wedge.

Step 9

Flip the red engine ON/OFF switch to the ON position.
Pull the motor's pull-start cable to start the motor.

Step 10

Use the control valve lever to retract the cutting wedge until it is seated underneath the dislodger bracket.
Retracting the cutting head reduces the amount of hydraulic fluid inside the cylinder, resulting in less spillage.

Step 11

Residual hydraulic fluid will be trapped in the hoses connected to the cylinder, and will drip out during the following procedure.
Place a bucket underneath the device, below the cylinder to catch any hydraulic fluid drips.
Have rags handy to stop drips and clean up affected areas.

Step 12

Use an adjustable wrench to loosen the nut securing the piston extension hose to the L-fitting on the side of the cylinder.

Step 13

Remove the piston extension hose from the L-fitting.
This hose will have excess hydraulic fluid, so tilt it down towards the catch bucket and let the fluid drain out.

Step 14

Use an adjustable wrench to loosen the nut securing the L-fitting to the side of the cylinder.

Step 15

Use an adjustable wrench on the L-fitting itself to rotate it to a vertical position with the opening facing down.
This allows excess hydraulic fluid to drip out. Keep a bucket underneath the device to catch drips.

Step 16

Use an adjustable wrench to loosen the nut securing the control valve to the fitting on the cylinder.

Step 17

Use an adjustable wrench to loosen the fitting on the cylinder.

Step 18

Slightly bend the control valve assembly away from the device to create a gap large enough for the fitting to clear.
Remove the fitting.

Step 19

Shim the cylinder with wood blocks to keep it at its resting height, parallel to the frame.

Step 20

Pull to remove the two cotter pins securing the large pivot pin.

Step 21

Remove the pivot pin.
The cylinder should now be resting on the wood shims.

Step 22

The following steps require two people.
The cylinder and wedge assembly is extremely heavy, so use caution.
Shift the cylinder and wedge assembly towards the rear of the device, until it clears the central pin hole.
