the shipment is complete; then carefully inspect for 

damage. Any evidence of rough handling may be 

an indication of hidden damage. 

 

Note - Shipping damages are not covered by the 

warranty; the carrier assumes responsibility for 

safe delivery. If you note damage or missing items, 

IMMEDIATELY file a claim with the carrier. At the 

same time, notify DSI/Dynamatic®. If assistance is 

needed to settle a claim, contact the factory. To 

expedite this service, refer to your equipment by 

purchase order, Model, Pro and Serial Numbers. 

 

The following check list is included-to assist with 

the receiving inspection. 

 

1.  Inspect the packaging, covering and 

skid for signs of mistreatment. 

 

2.  Inspect the housing to make sure there is no 

damage. 

3.  Manually rotate shaft to be sure it is free from 

binding and noise. 
4. Check for moisture and foreign material in 

the unit, especially on electrical windings, 

around the shaft and bearing caps and in 

accessories. 

 

Handling 

 

Only skilled personnel, following standard 

safety practices, should handle this 

equipment. Avoid jarring or pounding on shaft. 

Do not attempt lifting by the shaft.  Handling is 

best accomplished with a fork lift or crane. 

When using a fork lift, be sure the unit is well 

supported, with the forks adequately spread and 

centered under the skid. 

 

The units can also be lifted by a crane. To avoid 

damage, attach the crane cables to all eye bolts 

provided on the unit. 

 

Units mounted on a common base with other 

equipment may be lifted with a suitable sling under 

the base or by attaching cables to eye bolts 

designed and installed into the base for lifting the 

complete assembly. Refer to the certified drawings. 

Do not use the  eye bolts on the unit if the unit is 

attached to another piece of machinery or gear box, 

unless the drawings show they were designed for 

lifting the assembly. When two or more cables are 

used, maintain a near-vertical pull on the eye bolts. 

If near-vertical pull is not possible, use a spreader 

bar to take side pull off of the eye bolts. 

 

Storage 

 

Whenever this unit is to be set aside in storage, a 

clean, dry area must be provided, and it should be 

kept in its original crate. If kept in an air tight 

material such as polyethylene, silica-gel or some 

other moisture absorbent should be used to 

prevent rust. Additional grease is not required until 

ready for operation. Shaft should be rotated 

occasionally to redistribute bearing grease and to 

prevent bearings from becoming brinelled.
