Caution
If the tow chains are not properly installed, damage
to the tie rod could result. Make certain the tow chain
on the right side of the machine goes over the tie
rod and not under it.
5. Attach the two tow bar chains to the tie-down lugs.
Make certain that the chain goes over the tie rod as
shown in Figure 10.6.
6. Attach the ring end of the tow bar to the tow ve-
hicle.
7. Rotate the turntable so the counterweight is back at
the front of the chassis. Raise the platform about 3′
(1 m) above the ground.
8. Shut the engine off and turn the battery disconnect
switch off.
9. Pull the steering float valve knob (refer to Figure
10.8) up and twist it to lock it in position. The knob
is located on the top of the chassis, below the boom
lift cylinder, behind the rear door on the right side of
the turntable next to the fuel tank.

10. At each drive wheel, remove the two bolts from the
disconnect plate (refer to Figure 10.9). Turn the plate
over so the nipple points inward. Reinstall the two
bolts.

11. Do not exceed 10 mph (16 km/h) when towing. Use
caution when traveling around a curve or when
turning a corner. If a corner is turned too tightly the
steering mechanism might be damaged or the tow
vehicle and the aerial platform could jackknife.
Warning
The aerial platform is free to move when the drive
hubs are disabled. Death or serious injury can re-
sult. Re-enable the drive hubs before operating the
aerial platform.
12. After towing, pull and twist, then push the steering
float valve knob in.
13. At each drive wheel, remove the two bolts and return
the plate to its original position as shown in Figure
10.9.
14. Unfasten the tow vehicle from the machine and
replace the tow bar on the storage cradles.
15. Verify that the drive system operates properly.
