Operation
• Connect the towing chains to the tie down locations
(C).
• Avoid sharp turns when towing. Do not cross any
obstacles more than 12 in (30.5 cm) deep.

Telemetry (If Equipped)
The digital telemetry option enables the operator to
remotely monitor the unit fuel level. A transmitter inside
the engine compartment sends real time equipment
status information to the user via cellular or satellite
connection.
Spark Arrester (If Equipped)
A spark arrester, installed on the unit exhaust, may be
required by code in certain municipalities. Contact the
local authority having jurisdiction to determine if a spark
arrester must be installed on the unit before operation.
Heated Fuel Filter (If Equipped)
See Figure 3-20. An optional heated fuel filter (A) pre-
vents diesel fuel from gelling in extremely cold tempera-
tures. Heating cycles are automatically controlled by the
Power Zone–DLA.

Towing the Unit
Once the engine is shut down and the mast and lights are
correctly stowed, proceed as follows to prepare the unit
for towing.
1. Raise the outrigger jacks completely and release
the locking pins to rotate them up into the travel
position. Verify the locking pins snap into place.
Release the outrigger locking pins and slide the
outriggers into the trailer frame until the locking
pins snap into place.
2. Use the tongue jack to raise or lower the trailer
onto the hitch of the towing vehicle. Lock the hitch
coupling and attach the safety chains or cables to
the vehicle. Remove the tongue jack locking pin
and rotate the jack into the travel position. Replace
the locking pin.
3. To ensure correct operation of the jacks, refer to
Trailer Wheel Bearings. For maintenance interval
information, refer to Basic Maintenance Sched-
ule.
4. Connect any trailer wiring to the tow vehicle. Inspect
for correct operation of the directional and brake
lights.
5. Verify the enclosure is correctly latched.
6. Check for correct inflation of the trailer tires. For
maximum tire pressures, refer to Specifications.
7. See Figure 3-21. Inspect the wheel lugs. Tighten
or replace any lugs that are loose or missing. If a
tire has been removed for axle service or replaced,
tighten the lugs, in the order shown, to the follow-
ing specifications:
Figure 3-21. Tightening Wheel Lugs
a. Start all lug nuts by hand.
b. First pass: tighten to 20-25 ft-lbs (27-33 Nm).
c. Second pass: tighten to 50-60 ft-lbs (67-81 Nm).
d. Third pass: tighten to 90-120 ft-lbs (122-162 Nm).
NOTE: After the first road use, torque the lug nuts in
sequence.
8. Maximum recommended speed for highway towing
is 45 mph (72 km/h). Recommended off-road
towing speed is not to exceed 10 mph (16 km/h) or
less, depending on the terrain.
