3.1 Manual, Electric & Major Equipment Use and Maintenance

Manual Tools

Manual tools are the hand-held instruments a stylist manipulates directly: shears, razors, combs, clips, and brushes. Mastery of these is foundational because every cut, section, and finish depends on them.

Shears (Scissors)

Shears are precision cutting instruments and the stylist's primary tool. A professional shear has several named parts the Red Seal exam expects you to identify:

Edge Types

Two edge geometries dominate salon shears:

• Convex edge — The blade is ground to a curved, razor-like bevel (sometimes called a hammered or clamshell edge). It produces an exceptionally sharp, smooth cut that slides through hair with minimal push, making it the choice for precision and slide cutting. Convex edges are harder to sharpen and more delicate, typically made from harder steels (e.g., Hitachi 440C, VG-10, cobalt alloys).
• Bevelled edge — The blade has a flat, angled bevel along the cutting surface. It is less sharp than convex but tougher and easier to maintain; it excels at blunt, heavy, and dry cutting. Most entry-level and barbering shears are bevelled.

Tension Adjustment

Shear tension is set at the pivot. Correct tension lets the blades close with a clean 'snip' and open under their own weight when held point-down. Too tight: hair folds or pushes; too loose: hair bends between the blades. Adjust after cleaning and oiling.

Oiling and Sharpening

• Oil daily — one drop of clipper/shear oil at the pivot and along the ride area, then open/close several times and wipe excess. This prevents metal-on-metal wear.
• Sharpen only when the edge dulls, typically every 4–12 months depending on use. Convex shears must be sharpened on a waterstone or hone (flat hone), never a clipper-style wheel grinder, which ruins the convex curve.

Razors, Combs, Clips, Brushes

• Razors — Used for texturizing, thinning, and softening weight lines. The cutting edge faces the stylist; a guard razor is safer for new clients and reduces nicks. Change blades between clients to satisfy sanitation.
• Combs — Cutting comb (fine/medium teeth), wide-tooth comb (detangling curly/wet hair), rat-tail comb (sectioning and teasing). Comb teeth must be free of nicks that snag hair.
• Clips (sectioning clips) — Duckbill, butterfly, and alligator clips hold sections out of the way. They must grip without creasing or marking the hair.
• Brushes — Paddle brush (smoothing, detangling), round brush (blow-drying volume and curl), venting brush (speed drying), boar bristle (distributing oil, smoothing fine hair). Clean brushes of hair and wash weekly; sanitize between clients.

Electric Tools

Clippers

Clippers cut hair close to the scalp using oscillating blades. Three motor types:

Detachable blades are labelled by number, and blade numbering runs opposite to guard numbering: the higher the blade number, the shorter the cut. Guard combs snap over the blade to leave longer lengths, and there the higher number leaves more hair. Mixing the two conventions up is a classic exam trap.

Clipper Guard Size Reference

Blade numbers (used bare, without a guard) run the other way — higher number, shorter cut:

So a #40 blade cuts far shorter than a #10, while a #4 guard leaves far more hair than a #1 guard.

Trimmers (Edgers)

Trimmers are smaller, lighter clippers used for necklines, around ears, and detail work. They typically use fixed/adjustable T-blades. Clean, oil, and sanitize exactly like full-size clippers.

Blow-Dryers

A salon blow-dryer ranges from 1800 to 2200 watts. Wattage is the dryer's total electrical power draw, and the great majority of it feeds the heating element rather than the motor — which is why a higher-wattage dryer generally runs hotter and dries faster. Airflow volume is a separate specification (often quoted in m³/min or CFM) set by the motor and fan, and heat is regulated independently by the temperature switch, so a high-wattage dryer on a cool setting still moves plenty of air.

Common attachments:

• Concentrator nozzle — directs airflow in a flat stream for smooth, straight blow-dries
• Diffuser — disperses airflow to enhance curls and reduce frizz
• Pik — lifts roots and adds volume in textured hair

Major Equipment

• Hydraulic chairs — Pump or pneumatic; inspect for oil leaks; never overload beyond weight rating. Adjust height before the client sits to protect the cylinder.
• Shampoo bowls — Check water temperature (warm, ~38 °C / 100 °F), pressure, and neck-rest comfort. Clean spray nozzles weekly to remove mineral buildup.
• Hood dryers — Set timer and heat; ensure the hood clears the client's head; never leave a client unattended under a hot hood.
• Sterilizers / storage cabinets — Only an autoclave (or a validated dry-heat or chemical sterilant) actually sterilizes. A UV cabinet is not a sterilizer: it is a clean, covered storage unit for implements that have already been cleaned and disinfected, and many public-health authorities allow it only for storage. Verify contact time and use per the manufacturer and your provincial personal-service-setting regulation.

Sanitation vs. Disinfection vs. Sterilization

These three terms are NOT interchangeable on the exam:

• Sanitation — Cleaning to remove visible dirt, oil, and debris; the first step before higher-level decontamination. Soap and water is typical.
• Disinfection — Chemicals that destroy most pathogens on hard, non-porous surfaces; implements must be cleaned first. Barbicide, 70% alcohol, and other hospital-grade disinfectants carrying a Health Canada DIN.
• Sterilization — Total destruction of all microbial life including spores; autoclaves, dry-heat sterilizers, chemical sterilants.

Safe Operation, Cord Safety & Ergonomics

• Inspect cords before each use: replace if frayed, cracked, or the plug is damaged. Never wrap a cord tightly around the appliance (stresses the strain relief).
• Keep cords off wet floors; use GFCI-protected outlets near shampoo bowls.
• Ergonomics: keep wrists neutral, raise/lower the chair to working height, alternate standing/sitting, and use both hands on heavy tools to prevent repetitive strain injury.
• Clean, oil, and inspect clippers daily; replace blades when teeth chip.
• Always unplug before cleaning or changing attachments.
