Hydraulic fluid injection hazard.
High-pressure fluid can be injected under the skin and lead to serious injury,
including amputation.
- Make sure all accessories are tight before applying pressure. Relieve system
pressure before turning the machine back on.

- If an injection occurs in the skin, look for it immediately
