Step 1

Which TWO safety precautions must be observed when working with a coil spring compressor?

96%

114 rated

Answer

Ensure that the diameter of the compressor bolts can withstand the pressure of the coil spring.
Do not exceed the maximum pressure while operating the compressor.

Step 2

State THREE safety precautions that should be observed before pressing a bearing from a shaft using a hydraulic press.

99%

104 rated

Answer

Take notice of the predetermined pressure of the hydraulic press.
Ensure that the pressure gauge is in good working order.
Check that the platform holding the workpiece is rigid and square with the cylinder of the press.

Step 3

State TWO safety precautions to be considered when using the beam-bending tester.

96%

101 rated

Answer

Ensure the beam is securely clamped to the backboard to prevent movement.
Do not leave plastic beams loaded on the tester for long periods, as they may deform.

Step 4

Name ONE distinct safety precaution when using EACH of the following items of testing equipment:

98%

120 rated

Answer

2.4.1 Brinell tester: The tester must be mounted rigidly on a worktable.

2.4.2 Gear and bearing puller: Ensure that the puller is at a 90° angle to the workpiece before attempting to pull.

2.4.3 Torsion tester: Obtain specification (torsion) and materials details for the rods before conducting tests.
