On small screens, the overview shows every component and label. Swipe or scroll the detailed view horizontally to read the callouts, or enlarge the artwork. The complete numbered parts list follows below.
  1. Cutting blade

    A compatible toothed accessory oscillates through a short arc.

  2. Blade clamp group

    Front lever and mount retain the accessory at the output.

  3. Front drive head

    Cast head contains the oscillating output driven from the motor shaft.

  4. Brushless motor carrier

    Documented motor assembly lies on the main tool axis behind the drive head.

  5. Trigger and control carrier

    Control assembly sits within the hand-grip housing.

  6. Housing halves

    Two molded outer shells enclose the motor and controls.

  7. Battery interface

    Rear slide connection links the pack to the tool.

  8. Removable battery

    External compatible pack slides off before accessory changes.

02 / Understand the tool

What it is and what each part does

The DeWalt DCS356B Type 2 is a 20V MAX brushless, cordless, three-speed oscillating multi-tool with variable-speed trigger, Quick-Change accessory clamp and front LED. Its battery and charger are sold separately in the tool-only package. The original illustration neutralizes exterior color and markings while preserving the visible form and controls. Oscillation gives a short side-to-side accessory motion; it is not a spinning rotary cutter or a full-stroke reciprocating saw.

A charged compatible battery slides onto the rear shoe. The trigger controls a brushless drive, while the speed selector sets one of three ranges. The head oscillates an installed blade or sanding attachment through a small arc. The spring-loaded accessory clamp allows blade changes as described in the official manual. The Type 2 parts drawing supports the study's separated housing halves, motor/control carrier, front drive head, clamp, blade and battery. It is an educational arrangement, not a user teardown sequence.

Oscillating head

Enclosed drive converts motor rotation to a small accessory swing; its internals are not represented as user-service parts.

Quick-Change clamp and blade

The front lever releases a compatible blade. Teeth, blade shape and mounting interface must match the task and tool.

Trigger, speed selector and light

The variable trigger meters motion, the body selector chooses a range, and the LED illuminates the cut area.

Battery shoe and pack

The rear slide interface accepts a compatible battery. Remove the pack before changing accessories or maintaining the tool.

02 / Working principle

Set, guide and control the action

These decisions make the mechanism useful at the bench.

Fit the accessory

Remove the battery, open the clamp as the manual directs, position a compatible blade at the needed angle and ensure it locks.

Select speed and stance

Set an appropriate range, secure the work and hold the body so the blade cannot contact a hidden hazard.

Let teeth work

Start gently, use shallow pressure and control plunge depth; forcing the blade overheats it and worsens accuracy.

Flush trim

Use a suitable flush-cut blade with a protective shim where a finished face could be scratched.

Plunge an opening

Start on the waste side and advance gradually within the blade's rated material and depth.

Scrape or sand

Fit the maker-approved scraper or sanding pad for adhesive cleanup and small detail areas.

Setup, technique and finish quality

Use the steps for a first pass, then inspect the work before changing the setup.

  1. Inspect the tool, battery, clamp and accessory for damage; locate hidden wires, pipes and fasteners.
  2. Remove the battery and fit a compatible blade with the clamp fully locked.
  3. Clamp the work and choose a speed range suitable for the material and accessory.
  4. Grip the body securely, place the blade clear of the work and start with the variable trigger.
  5. Guide the accessory with light pressure, allowing the oscillating teeth to cut; pause to limit heat.
  6. Release the trigger, let the blade stop, remove the battery and handle the hot accessory cautiously.

Small arc, controlled access

A short oscillating sweep permits close and flush work, but the exposed blade can still cut deeply and rapidly.

Accessories are task-specific

Wood, metal, scraper and sanding accessories differ. Select material rating and interface from the maker's documentation.

Drive groups are educational

The official parts drawing distinguishes housing, motor carrier and front drive components. Their separated view explains power flow; owners should follow the manual for ordinary blade and battery changes only.

What changes by model or material

Corded or cordless

Corded versions suit long duty cycles; cordless versions need compatible charged packs.

Mounting interfaces

Tool-free and bolted mounts vary. Check genuine accessory compatibility and lock engagement.

Speed control

Some tools use dial, selector or trigger control; the illustrated DCS356B has a three-speed selector and variable trigger.

Choosing the tool

  • Choose an accessory system with blades and pads suited to your work.
  • Check comfort, light placement, speed control and battery compatibility.
  • Compare documented oscillation angle and material ratings rather than relying on appearance.

Useful accessories

  • Compatible wood or bi-metal blade
  • Scraper blade
  • Detail sanding pad
  • Dust collection where a compatible attachment is offered

Consumables

  • Replacement blades
  • Sanding sheets
  • Compatible battery pack
04 / Keep control

Care, troubleshooting and safety

Stop the tool and disconnect power before investigating a fault or changing a part.

Care checklist

  • Remove the pack before cleaning or accessory changes.
  • Clear dust from vents and clamp without washing or opening the housing.
  • Inspect blades for lost teeth, heat damage or cracks.
  • Store battery and tool according to the manufacturer manual.

Common mistakes

  • Starting with the blade touching the work.
  • Forcing a dull blade into metal or a hidden fastener.
  • Using an incompatible mount or leaving the clamp partly engaged.
  • Applying pressure that burns wood and shortens blade life.

Safety at the operation

  • Read the official manual and wear eye, hearing and suitable respiratory protection.
  • Locate hidden services before plunge cuts and secure the work.
  • Remove the battery before blade changes, inspection or storage.
  • Treat the accessory as hot and sharp immediately after use.
  • Keep hands behind the cutting edge and manage dust appropriate to the material.

When the result goes wrong

Blade chatters or slips

Stop, remove the battery and inspect accessory fit, clamp seating and blade damage.

Cut is slow or scorched

Use a sharp blade rated for the material, lighten pressure and choose a suitable speed range.

Tool will not start

Check battery charge and engagement, then follow the manual's fault guidance; do not bypass safety controls.
