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 tool box, located the hydraulic pump gun and allen
wrench (21), the hydraulic fitting wrench (22) the brake
release fitting (23) and needle valve screw (24).
2. Using the allen wrench, loosen the needle valve screw
on the hydraulic block by backing it out 2 complete turns.
Do not remove. (24).
3. Loosen the hydraulic brake release fitting (23) using the
supplied wrench (22) 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 (25).
5. Open the valve on the gun (26) (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. 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).
• 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.
