Question: When attaching hydraulic hoses to an implement, why is it crucial to ensure they are not twisted or kinked?
Answer options:
- Twisted hoses are difficult to disconnect later. ✅ Twisting can restrict fluid flow, generate heat, and weaken the hose material.
- Kinked hoses can prematurely wear the hose's outer cover.
