Blade and flanges
The blade seats on the spindle between inner and outer flanges under the specified bolt. Check diameter, arbor, tooth direction and speed rating.

02 / Understand the tool
What it is and what each part does
A handheld circular saw moves through stationary, supported wood while its shoe rides the surface. The Makita 5007MG is a corded sidewinder with a 7¼-inch blade; its motor lies across the blade drive, unlike a worm-drive configuration. A track saw has a dedicated rail and plunge system, so a straightedge-guided circular saw should not be described as one.
The motor turns a spindle and arbor, which hold the blade between flanges. A fixed upper guard covers the top; a spring-return lower guard exposes the teeth only as the cut advances. The shoe establishes depth and bevel, and remains supported on the work. The poster separates documented groups for education, not service order.
Two guards
The upper guard is fixed. The lower guard retracts during the cut and must spring closed freely when the saw leaves the work.
Motor and gearbox
The 5007MG is a sidewinder. Its field, armature and spindle drive are identified in the official parts breakdown.
Shoe and adjustments
The base rides on stock; depth and bevel levers lock its position relative to the blade.
Handles and trigger
Two-hand control helps keep the saw aligned while the blade enters and exits. Keep the cord behind the cut.
Cut line and extraction
The model's cut-line features help alignment, but test the true blade offset. Manage dust without blocking the lower guard.

02 / Working principle
Set, guide and control the action
These decisions make the mechanism useful at the bench.
Support both sides
Support the panel so neither kerf nor offcut binds the blade. Keep the section under the shoe stable throughout the cut.
Set depth
With power disconnected, set the model's depth lever so the blade projects only as the manual directs below the work, then lock it.
Guide the shoe
Keep the broad shoe flat on the material. Check straightedge offset and blade clearance before starting.
Break down sheet goods
Use a stable sacrificial support or equivalent arrangement that keeps the whole sheet from sagging into the kerf.
Crosscut boards
Mark the waste side, clamp or otherwise secure the board, and use a square or guide where needed.
Bevel edge
Set and lock bevel angle, check shoe support and test the changed blade-to-guide offset in scrap.

Setup, technique and finish quality
Use the steps for a first pass, then inspect the work before changing the setup.
- Read the 5007MG manual; select a compatible blade for wood and the intended cut.
- Unplug the saw; inspect blade, flange, guard spring, shoe, levers and cord.
- Support and secure the work so neither side can close onto the blade.
- Set depth and bevel, tighten locks and verify the guard returns freely.
- Plan a path that keeps the entire shoe supported and the cord outside the blade path.
- Start with blade clear, reach full speed, then feed without twisting or forcing.
- Release the trigger; keep the shoe controlled until the blade stops and guard closes before setting it down.
Kerf and offset
The blade removes material on one side of a line. The shoe edge is offset from the tooth path; measure that offset with the actual blade and bevel.
Kickback
A pinched, twisted or misaligned blade can drive the saw back. Support stock and stand clear of the blade line.
Guard check
Never tie open the lower guard. If it binds, stop and repair the guard before use.
Blade selection
Tooth count and grind affect chip clearance and edge finish. Use wood blades matching the model's diameter, bore and rating.
What changes by model or material
They package the motor and drive differently. Do not infer 5007MG parts or service steps for a worm-drive saw.
Battery models differ in weight, runtime and braking; exact manual and battery system govern.
Blade placement changes sightline and where most of the shoe supports the cut. Check each model.
A track saw's dedicated rail and plunge action form a different guided system.
Choosing the tool
- Match blade size and maximum depth to stock thickness.
- Compare shoe rigidity, balance, guard action, bevel locks and blade visibility.
- Plan support and a straightedge before relying on advertised cut capacity.
Useful accessories
- Clamped straightedge or compatible guide.
- Stable sheet support.
- Dust connection where specified by the model.
Consumables
- Compatible wood-cutting blades.
- Replacement lower-guard spring or shoe parts when serviced per manual.
- Extraction filters.
04 / Keep control
Care, troubleshooting and safety
Stop the tool and disconnect power before investigating a fault or changing a part.
Care checklist
- Unplug before blade changes.
- Clean pitch and dust from guards, shoe and vents.
- Test lower-guard spring action every use.
- Replace damaged cord or loose depth/bevel lock parts.
Common mistakes
- Supporting only the middle of a sheet and pinching the kerf.
- Using a dull or wrong-size blade.
- Starting with teeth touching stock.
- Setting down a coasting saw before guard closure.
Safety at the operation
- Use eye and hearing protection and control dust.
- Keep both hands on the intended grips and below neither workpiece nor shoe.
- Never defeat the lower guard.
- Keep the cord and loose material away from the blade path.
When the result goes wrong
Check straightedge security, shoe contact, blade condition and feed force.
Stop immediately; check stock support, kerf closure, blade sharpness and alignment.
Unplug and inspect the guard path and spring; do not operate until repaired.
