Check for signs of oil breakdown

Measure temperature on the bearing housing face using a magnetic thermometer

Measure temperature on the bearing housing rim using a magnetic thermometer

Check for hot spots using a hand held digital heat scanning device

Is any bearing cover showing more than 180°F (82°C)?

Check wire weave for breaks, tears or separation of the wire.

Replace wire that exhibits any damage.

Are there any panels with 'dead spots' where material is puddling?

Replace wire panels that no longer maintain tension over the complete surface area.

Consult Telsmith Engineering Department before proceeding with any change in counterweight balance shims.

Remove the two hex head capscrews holding the counterweight shim stack to the face of the counterweight.

Slide the shims out one at a time off the counterweight hub and lower to the floor.

If additional shims are required, slide them on the counterweight hub.

Fasten the shims in position with the two hex head capscrews ensuring proper engagement with the counterweight hub.

Lockout/Tagout power to screen as detailed in Chapter 1.

Remove the drive belt(s) from the electric motor(s) as detailed in Chapter 3.

Remove the friction dampening puck from each base assembly.

Lift the screen several inches off the screen springs and base frame using a lift hoist and spreader frame.

Block the screen up on blocking of sufficient capacity to support the screen.
