INSPECTION OF UNIT 

 

Thoroughly inspect the equipment for any shipping and handling damage before accepting shipment from the freight company.  If any of the 
goods called for in the bill of lading or express receipt are damaged or the quantity is short, do not accept until the freight or express agent 
makes an appropriate notation on your freight bill or express receipt.  If any concealed loss or damage is discovered later, notify your freight 
carrier or express agent at once and request him to make an inspection.  We will be very happy to assist you in collecting claims for loss or 
damage during shipment; however, this willingness on our part does not remove the transportation company’s responsibility in reimbursing 
you for collection of claims or replacement of material.  Claims for loss or damage in shipment must not be deducted from the NORD Gear 
invoice, nor should payment of the NORD Gear invoice be withheld awaiting adjustment of such claims, as the carrier guarantees safe 
delivery.   
 
If considerable damage has been incurred and the situation is urgent, contact the nearest NORD Gear Sales Office for assistance.  Please 
keep a written record of all communications. 
 
 

 

RECORD NAMEPLATE DATA 

 

Locate the gear reducer nameplate and record all nameplate data for future reference.

STORAGE 

 

PROPER STORAGE UNTIL INSTALLED 

Keep unit in a dry, temperature controlled area.  If stored other 
than said, long term storage methods must be applied to the unit 
including complete fill with lubricant. Protect machined surfaces 
and rotate shafts periodically.  Prior to putting unit into service, 
drain lubricant and refill to proper level as determined by the 
mounting position. 

 
PROPER HANDLING OF THE UNIT 

Exercise care to prevent damage to the unit when moving. Lift 
onIy at designed Iifting points.  Do not attach other machinery and 
lift by the unit lifting points.  The lifting points are to be used to lift 
the unit only.   Insure that adequate safety measures are taken to 
protect personneI during transportation.  Protect the mounting 
surface from damage.
