After you have unpacked the unit

Save all the packing materials - they will prove valuable should it become necessary to transport of ship
this product.

Please inspect this unit carefully for any signs of damage incurred during transportation.  It has undergone
stringent quality control inspection and tests prior to packing and left the factory in perfect operating and
mechanical condition.

If, however, the unit shows a sign of damage, notify the transportation company without delay.  Only
you, the consignee, may institute a claim against the carrier for damage during transportation.

If necessary, contact your supplier or as a last resort, your Klark Teknik importing agent, who will fully
co-operate under such circumstances.
