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

OIL SPECIFICATIONS NORD supplies aII reducers fiIIed with oiI from the factory. Consult the sticker adjacent to the fill plug to determine the type of lubricant installed at the factory. Standard lubricant is ISO VG220 mineral-based oil. However, some units have special lubricants designed to operate in certain environments or to extend the service life of the lubricant. - Page 7 Note: Filling quantities are approximate figures. Oil level must be checked according to oil level plug after final installation. Acceptable oil fill level is within ½ inch of the bottom of the fill plug threads For mounting angles not shown, consult factory. BIM 1011/2005/03 www.nord.com...
