BELT TENSIONERS
Kubota and Isuzu engines use only manual belt tensioners. John Deere engines use two types of belt tensioners:
manual and automatic. Adjust the belt using the manual tensioner according to the manufacturer’s specifications.
The automatic tensioner cannot be adjusted or repaired and is designed to maintain proper tension over the belt’s
life. Units with the automatic belt tensioner must be inspected according to the manufacturer’s specifications.
LIFTING THE GENERATOR
A central lift point is located on the top of the generator. The
central lift point is connected to a lift structure inside the unit.
Attach a sling or hook directly to the central lift point only if the
devices are in good condition and the equipment being used
to raise the unit has sufficient capacity. For approximate
weights refer to the Specifications section,

.
Always remain aware of others around you when moving or
lifting the generator. Keep the cabinet doors closed and locked.
TOWING THE TRAILER
1. Use the 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. Release the
jack locking pin and rotate the jack into the travel position. Make sure the locking pin snaps into place.
2. Connect any trailer wiring to the tow vehicle. Check for proper operation of the stop and signal lights.
3. Make sure all doors are closed and secure.
4. Check for proper inflation of the trailer tires. For maximum tire pressures, refer to the Specifications section,

5. Check the wheel lugs, tighten or replace any 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 following specifications:
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, re-torque the lug nuts in
sequence.
6. 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 terrain.
TRAILER WHEEL BEARINGS
Some trailers are equipped with a grease zerk fitting to allow lubrication of the wheel bearings without the need to
disassemble the axle hub. To lubricate the axle bearings, remove the small rubber plug on the grease cap, attach a
standard grease gun fitting to the grease zerk fitting and pump grease into the fitting until new grease is visible around
the nozzle of the grease gun. Use only a high quality grease made specifically for lubrication of wheel bearings. Wipe
any excess grease from the hub with a clean cloth and replace the rubber plug when finished. The minimum
recommended lubrication is every 12 months or 12,000 miles (19,312 km). More frequent lubrication may be required
under extremely dusty or damp operating conditions.
