Please consult your manual for full information or consult your local dealer.

The generating set should only be lifted using  
the designated lifting points or the fork pockets 
where provided. 

Do not lift the unit by the alternator or engine 
lifting eyes. These are designed only to carry the 
weight of the specific unit (engine or alternator) 
and not for the weight of the fully assembled 
generating set.

For movement on site the optional fork pockets 
enable the generating set to be lifted and shifted 
by a forklift or telescopic handler. The fork 
pockets are sized and spaced to allow lifting by 
equipment with a stand fork carriage. 

Lifting

NOTE: Always ensure that lifting 
equipment is rated to lift the total 
load. While the weight of the 
generator is provided on the rating 
plate it will not include the optional 
trailer weight.
