A driver finds automatic slack adjusters far out of adjustment and plans to hand-adjust them quickly without training. What is the safest manual-based response?

1. Do not hand-adjust unless thoroughly trained; have a qualified mechanic inspect badly out-of-adjustment automatic adjusters
2. Hand-adjust them at every stop regardless of training
3. Ignore the problem because automatic adjusters never need service
4. Disconnect the chambers so the pushrods no longer move
