Difficulty: EasyDirect Fact Retrieval

Before operating a portable hydraulic rescue cutter, rescue personnel must check the hydraulic fluid reservoir sight gauge. The fluid level must be positioned between the two red indicator lines when the cutting tool is fully open. If the reservoir fluid appears milky or discolored, the operator must immediately replace the fluid rather than adding more. Operating the cutter with contaminated hydraulic fluid will cause internal pump seal failure.

According to the passage, what should an operator do if the rescue cutter's hydraulic fluid appears milky?

  1. A
    Add fresh hydraulic fluid until the level reaches the upper red indicator line.
  2. Immediately replace the hydraulic fluid.Answer
  3. C
    Replace the internal pump seals before using the cutter.
  4. D
    Open the cutting tool fully and continue normal operation.
