Operation

Transporting in Freewheel Mode

In the event of a machine malfunction, the stump cutter may be
towed a short distance by using the wheel drive disconnect.
This procedure should be used to move the machine in the
event that it can not power itself to the desired spot to be
repaired. Before using the freewheel disconnect make sure
the wheels are choked.

Disable The Wheel Motors

To disengage the wheel drive motors perform the following
steps:

1. In the box on the right hand side, locate the hydraulic

pump gun (21), allen wrench (22), and the double ended

wrench (used to secure the hand pump).

2. Using the double end wrench, and the allen wrench,

loosen the needle valve screw on the hydraulic block

(24) by backing it out 2 complete turns. Do not remove.

3. Loosen the hydraulic brake release fitting using the

double ended wrench and push the hose aside, taking

care to prevent excessive fluid spillage.

4. Keeping the gun inverted, use the wrench to tighten the

gun on the brake release fitting. (26)

5. Open the valve (25) on the gun (turn in-line with the

barrel), and pump 10-15 times.

6. Immediately close the valve (cross-ways with the barrel)

on the gun to hold pressure in the line.

7. The machine can now be towed or pushed to a location

for service. Great care should be taken when loading

on a trailer.

8. During transport on a trailer, the brakes should be re-

engaged to properly secure the machine (see steps

below to re-engage the brakes).

Re-engage The Wheel Motors

1. Reopen the valve on the gun(25). This will allow the

charged hydraulic fluid to drain back into the gun.

2. Disconnect the gun from the brake release fitting using

the wrench.

3. You may now empty the remaining fluid back into the

plastic bottle from the gun.

4. Reconnect hydraulic hose the brake release fitting you

removed earlier in step 3.

5. Tighten the needle valve screw loosened in step 2.
6. If the proper repairs have been made to the machine, you

may follow the starting procedure outline in this manual.

Dual Wheels

The dual wheels provide increased stability & traction, yet
can be easily removed for maneuvering machine through
tight spots. To remove a wheel:

• Drive the rear inside wheel onto a small wooden board

so that the outer wheel is slightly raised off of the ground.

• Loosen the bolt (27) using the provided tool (28) located

in the battery compartment.

• Remove the outer wheel.
• Place the outer wheel, washer and bolt in safe-keeping

until needed again.

• To remount the wheel, reverse the above procedure.

Tighten the bolt firmly but do not exceed 80 ft/lbs.

Note: In instances where the above procedure is not possible,
a 4x4 (or similar material) can be placed under the blade to
aid in lifting the machine. Use extreme caution when doing
so as this decreases machine stability.

NOTE: TORQUE BOLTS TO 80 FT-LBS

CAUTION - EXCESSIVE TORQUE WILL

DISTORT BACKING PLATE
