Once the oven has been removed from the delivery vehicle, it can easily be
moved on smooth, flat surfaces using a Pallet Jack� To lift the oven with a Pallet
Jack, remove the front and rear angle iron stabilizers from the base of the oven
stand and place a stout 4x4 post through the Fork Pocket as shown in figure b�

time with the trucking company before committing to heavy equipment and/or labor� Our goal is a smooth and safe delivery�
4x4 post
USING A CRANE.

oven, use a spreader bar with a two-legged sling rigged on each end� The
spreader bar should be of a sufficient length to keep the sling from contacting
the oven� See figure c�
DO NOT TURN THE OVEN ON ITS SIDE!
Contact Wood Stone if the oven must be turned on its side for specific instructions�
Moving a Wood Stone oven can present challenges to even the most experienced
riggers� Take your time, use your head, secure the proper equipment and make safety
your first priority� Please don’t hesitate to call the factory for technical support�
