7.0 Maintenance
In order to the maximum life of the 4SA Saddle machine, the maintenance should be performed by an
authorized Mathey Dearman Certified Repair Center. The Mathey Dearman Pipe Cutting and Beveling
Machines require 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. The bearings (Figure 5 item 5) in the Single Bearing Brackets (Figure
5) and the bearings (Figure 6 item 7) in the Double Bearing Bracket (Figure 6) are sealed lubricated bearings
and should never require replacement.
There are 2 thread holes in the side of the Single Bearing Bracket (Figure 6) containing a set screws (Figure 6
item 8) and 2 thread holes in the side of the Double Bearing Bracket (Figure 6) containing a set screws
(Figure 6 item 9). These Set Screws should never be loosened or removed except to replace the bearings
(Figure 5 item 5) (Figure 6 item 7).
