7.0 Maintenance
In order to the maximum life of the 1SA Saddle machine, the maintenance should be performed by an authorized Mathey
Dearman Certified Repair Center. The Mathey Dearman Pipe Cutting and Beveling Machine requires only minimal
maintenance; however, these are precision machines. In order to achieve proper results, make sure your machine is
handled with reasonable care and it kept clean and lubricated. The machine should be stored in a protective container
such as a Mathey Dearman Machine Storage Box or the original factory shipping crate during transporting or when not in
use.
The Ring Gear, Pinion Gears, and Drive Chains should be kept clear of slag and other trapped abrasives, especially sand
and dirt. The Saddle, Ring Gear, and Cap Ring should be cleaned weekly and the Ring Gear Track Surfaces should be
coated with Lubriplate 130-AA or equal lubricant weekly under heavy use and before storing. The Drive Chains and
Sprockets should be cleaned regularly and coated with a film of a light oil or lubricant such as WD-40 or equal. Lithium
Grease should be applied to the Grease Zerk (Figure 5 item 9) of the Single Bearing Bracket (Figure 5) and to the Grease
Zerk (Figure 6 item 11) of the Double Bearing Bracket (Figure 6) weekly.
