The TSE Brake will remain engaged until sufficient air
pressure is applied to release it. Depending upon the
length of the air lines and the type of controls used, the
amount of release air may vary.
Apply increasing amounts of air pressure to the brake until
the Friction Disc Hub turns freely.
1. To manually release the TSE Brake, remove the three
Shoulder or Socket Head Cap Screws (Item 6) and
replace them with customer supplied cap screws (See
Table 4).
2. Tighten the cap screws alternately and evenly to draw
the Plate (Item 3) and Friction Facing (Item 5) away
from the Friction Disc Hub (Item 1).
MAINTENANCE
Periodically inspect all mounting bolts and air line fittings
to make sure they are securely tightened. Pay particular
attention to Shoulder Screws or Socket Head Cap Screws
(Item 6). If these screws are loose, the Cylinder (Item 10)
travel will increase, causing the O-ring Seals to leak air.
Tighten the Shoulder Screws or Socket Head Cap Screws
(Item 6) to the recommended torque (See Table 5).
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.

CAUTION
Do not use more air pressure than
required to release the brake (100 psi
maximum).
WARNING
Never exceed maximum operating speeds
listed for your product. (See Table 3).
CAUTION
CAUTION
TABLE 3
The temperature limits for this product
line are 4.5-104 Degree Celsius (40-
220 Degree F).
Never exceed life of facing material. Facing
life depends on the volume of material and
the total energy over the life of the unit.
Expected life (in hrs) can be found by:
Time=Volume/(Power*Wear Rate).
