Step 1

Park the vehicle on level ground. The reservoir sight glass won't give an accurate reading if your Bradley is parked at an angle.

Step 2

Open the access door all the way before checking the fluid level. When the door is only partially open, you'll get a high reading because the hydraulic cylinders aren't fully extended. Later, when you drain extra FRH from the reservoir to bring down the level, the system is under-tilled. That lets air into the system and may keep the door from opening.

Open the access door to the fourth detent on the support link. That's fully open.

Step 3

Eyeball the fluid level in the reservoir. The level in the sight glass should reach the full mark line inscribed on the reservoir.

If it doesn't add FRH until it reaches the line. If the level passes the mark, drain some of the fluid. Use an AOAP vampire pump, NSN 4930-01-119-4030, to remove the excess fluid.

An Extra Step

While you're checking the sight glass, pay special attention to the color of the fluid. Fluid that is milky is probably contaminated with water. Let your mechanic know right away since contaminated fluid will ruin the seals.
