Before removing the filler cap of a pressurized hydraulic reservoir, you should

  1. heat the reservoir

  2. relieve the air pressure

  3. check the fluid level

  4. cool down the reservoir

The correct answer is: relieve the air pressure

Before removing the filler cap of a pressurized hydraulic reservoir, it is crucial to relieve the air pressure to ensure safety. If the air pressure is not relieved, there is a risk of hydraulic fluid spraying out forcefully, causing injuries to anyone nearby and contaminating the work area. Therefore, by relieving the air pressure before opening the hydraulic reservoir, you can prevent any potential hazards and work on the system safely. Option A is incorrect because heating the reservoir is unnecessary and can even lead to an increase in pressure inside the reservoir, making it more dangerous to open. Option C, checking the fluid level, is also important but should be done after relieving the air pressure to avoid any accidents. Option D, cooling down the reservoir, is not necessary for the task of removing the filler cap.
