1. A weight-loaded accumulator:

1. loses pressure as fluid discharges
2. gains pressure as fluid discharges
3. stays at the same pressure as fluid discharges

2. A spring-loaded accumulator:

1. loses pressure as fluid discharges
2. gains pressure as fluid discharges
3. stays at the same pressure as fluid discharges

3. Gas charged accumulators use:

1. oxygen
2. nitrogen
3. argon

4. The most common accumulator application is:

1. supplementing pump flow
2. making up for system leaks
3. providing an emergency power supply

5. Precharge pressure should be checked at least every:

1. one to two months
2. two to three months
3. three to six months

6. An accumulator may be used to:

1. make a pump run faster
2. make a valve shift more quickly
3. make up for system leaks

7. Accumulator pre-charge pressure is normally.

1. 95% of minimum system pressure
2. 85% of minimum system pressure
3. 75% of minimum system pressure

8. When the pump is running, an accumulator dump valve keeps fluid:

1. from going to the accumulator
2. from going to the circuit
3. from going to tank

9. An unloading relief valve sends:

1. pump flow to tank at system pressure
2. accumulator flow to tank at system pressure
3. pump flow to tank at 25 to100 psi

10. This symbol represents a:

1. weight-loaded accumulator
2. gas-charged accumulator
3. spring-loaded accumulator
