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.
