Follow the checks below when hitching the generator to a vehicle and before every journey.

2. Turn the battery isolator key to "OFF" on the generator - remove key if you wish.
3. Ensure all electrical cables have been disconnected.
M12 wheel bolts. These must always only be tightened to the correct torque setting as shown. They should
be tightened in sequence, North, South, East, West and never clock or anti-clockwise. Always use a calibrated
torque wrench. It is dangerous to overtighten wheel bolts as it is to not tighten them sufficiently.
Wheels
The condition of the wheels and tyres should be checked regularly, particularly for distortion of flanges and
the wheel dish. Wheels that are damaged or distorted, or have wheel bolt seating's cracked or deformed
must not be repaired or used in service - these must be replaced.
Number Plate
It is a legal requirement to have a industry standard approved rear number plate fitted and clearly displayed
on the trailer with reference to the towing vehicle.

Safety Precautions
It is important that the wheel and hub/brake drum are compatible. This means that the PCD, wheel bolts and
inset must all be compatible with both the hub/brake drum and the wheel rim. Particular attention must be
paid to the recommended torque settings for the wheel bolts.
The axle type details shown on the axle type plates must not be obstructed or made illegible by application of
any additional surface finish.
