NOTE: Periodically inspect all mounting bolts and air line
fittings to make sure they are securely tightened. Pay
particular attention to the Flange Head Hex Screws (Item
6 or 16). If these screws are loose, the Piston Plate (Item
3) travel will increase, causing the O-ring Seals to leak air.
Tighten the Flange Head Hex Screws (Item 6 and16) to
the recommended torque (See Table 4).
Inspect Friction Facings (Item 5) for signs of wear and
replace if worn down to where the Machine Screws (Item
14) may score the Friction Disc Hub.

MAINTENANCE
MANUAL DISENGAGEMENT
1. To manually release the TSE Brake, first the air pressure
supply must be removed. (See CAUTION)
2. Remove the Flange Head Hex Screws (Item 16) from
the Piston (Item 2) and the Socket Head Cap Screws
(Item 6) from the opposing Piston Plate (Item 3).
3. Remove the Piston Plate (Item 3) and all three Spacers
(Item 15).
4. Replace Piston Plate (Item 3) and Socket Head Cap
Screws (Item 6) with longer customer supplied fasteners
(SAE Grade 8, 3/8-16) at least 4" long (TSE 1200)
and 5" long (TSE 1400). Cap screws must be long
enough, with sufficient thread length, to allow full removal
of spring force. Spring travel has been designed to
engage over entire area of friction material. Tighten
Cap Screws alternately and evenly to draw the Piston
Plate (Item 3) and Friction Facing (Item 5) away from
the Friction Disc-Hub (Item 1).
