CPG Equipment Maintenance & Sanitation 2 — Questions and Answers
Question 1: How often should clipper blades be oiled during a full grooming session?
- Once at the start only
- After every 10-15 minutes of use (Correct answer)
- Only when the blade feels hot
- Once at the end of the session
Correct answer: After every 10-15 minutes of use
Clipper blades should be oiled every 10-15 minutes of use to reduce friction, prevent overheating, and maintain cutting efficiency.
Question 2: Which solution is most appropriate for disinfecting grooming scissors between clients?
- Warm soapy water alone
- Isopropyl alcohol (70%) (Correct answer)
- Diluted white vinegar
- Plain cold water
Correct answer: Isopropyl alcohol (70%)
70% isopropyl alcohol effectively kills pathogens on scissor blades and evaporates quickly without causing rust damage.
Question 3: What is the primary reason for 'carding' a grooming table's rubber mat regularly?
- To increase grip for the dog
- To remove embedded hair and debris that harbor bacteria (Correct answer)
- To make the mat look cleaner for clients
- To prevent the mat from cracking
Correct answer: To remove embedded hair and debris that harbor bacteria
Carding or scrubbing the rubber mat removes embedded hair and organic debris that can harbor bacteria and mold.
Question 4: A groomer notices rust spots forming on clipper blades after cleaning. What is the most likely cause?
- Using blades too frequently
- Inadequate drying after washing or disinfecting (Correct answer)
- Incorrect blade tension setting
- Using the wrong clipper oil brand
Correct answer: Inadequate drying after washing or disinfecting
Rust develops when moisture remains on metal surfaces after washing; blades must be thoroughly dried immediately after cleaning.
Question 5: What does the term 'blade drive' refer to in clipper maintenance?
- The motor speed setting on the clipper
- The mechanism that moves the cutting blade back and forth (Correct answer)
- The rail system that holds the blade in place
- The electrical contact between blade and clipper body
Correct answer: The mechanism that moves the cutting blade back and forth
The blade drive is the component inside the clipper that transfers motor movement to the reciprocating cutting blade.
Question 6: Which type of cleaner should be AVOIDED on high-carbon steel shear blades?
- Blade wash spray
- Quaternary ammonium compound disinfectant
- Chlorine bleach solutions (Correct answer)
- Light clipper oil
Correct answer: Chlorine bleach solutions
Chlorine bleach is highly corrosive to high-carbon steel and will cause pitting and rust, permanently damaging the blade edges.
Question 7: When should a groomer replace a clipper drive cap (also called a comb drive)?
- Every 6 months regardless of condition
- When it shows visible wear, cracking, or causes blade chatter (Correct answer)
- Only when the clipper motor stops working
- Whenever the blade is replaced
Correct answer: When it shows visible wear, cracking, or causes blade chatter
A worn or cracked drive cap causes blade chatter, uneven cutting, and excess heat, and should be replaced when these symptoms appear.
