1. Remove resolver covers, inspect mechanical operation, and check for
condensation accumulation. If moisture exists, open all drain holes.
Apply a spray-type lubricant (WD-40 or equivalent) to all moving
parts. Secure covers.

type lubricant (WD-40 or equivalent) to chain and drive sprocket.
Inspect the drive chain for correct tension and lubricate if necessary
with the spray-type lubricant. Ensure that feed rollers are all
functional. Inspect flexible transmit waveguide, if applicable, for
fatigue. Check limit switch operation. Inspect feed window for
damage and replace window as required.
