General Safety Precautions:
- Wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, and gloves.
- Ensure your work area is clean, well-lit, and free from obstructions.
- Keep bystanders, especially children, away from the work area.
- Do not operate the tool in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Always maintain a firm grip on the tool and be aware of its kickback reduction system (AFT).
- Disconnect the battery pack before making any adjustments, changing accessories, or storing the tool.
IP56 Protection:
This tool features an IP56 dustproof and waterproof protection rating. This design provides resistance against dust ingress and water splashes, making it suitable for use in various job site conditions. However, this rating does not guarantee against malfunction if the tool is submerged in water or exposed to excessive dust. Always handle the tool with care.

- Use the hex wrench to loosen the arbor bolt.
- Remove the outer flange and old blade.
- Install the new blade with the teeth pointing in the direction of rotation (indicated by an arrow on the blade guard).
- Replace the outer flange and tighten the arbor bolt securely with the hex wrench while holding the shaft lock button.
Adjusting Cutting Depth:

Operating Instructions
Selecting Drive Mode:
The HS005GZB features two selectable drive modes for optimized performance:
- Speed Mode (Automatic Speed Change): Provides high-speed rotation (up to 6,000 RPM) for light loads and automatically applies high torque for heavy loads, ensuring fast cutting.
- Finish Mode (Constant Speed Control): Maintains a constant rotational speed (4,500 RPM) for strong adhesion and clean cut surfaces. This mode is ideal for renovation work and interior finishing due to its low noise operation.
Use the mode selection switch on the tool to toggle between Speed Mode and Finish Mode.

Making a Cut:
- Mark your cutting line on the workpiece.
- Adjust the cutting depth and bevel angle as required.
- Place the front edge of the saw base on the workpiece, ensuring the blade is clear of the material.
- Start the saw and allow the blade to reach full speed before engaging the material.
- Guide the saw smoothly along the cutting line, applying steady pressure. Do not force the tool.
- Once the cut is complete, release the trigger and allow the blade to stop completely before lifting the saw from the workpiece.
Edge Cutting and Bevel Cuts:
The HS005GZB allows for precise edge cutting by removing the separate base and sub-base. It also supports bevel cuts up to 15 degrees (left bevel).

Maintenance
Regular maintenance ensures the longevity and optimal performance of your circular saw.
- Cleaning: After each use, clean the tool thoroughly. Remove sawdust and debris from the blade guard, motor vents, and base plate. Use a soft cloth, and avoid using solvents that may damage plastic parts.
- Blade Inspection: Regularly inspect the saw blade for sharpness, damage, or missing teeth. Replace dull or damaged blades immediately to ensure safe and efficient cutting.
- Battery Care: Store batteries in a cool, dry place away from direct sunlight. Do not store fully discharged batteries for extended periods.
- General Inspection: Periodically check all screws and fasteners for tightness. Ensure all moving parts operate smoothly.
For any repairs or servicing beyond routine maintenance, contact an authorized Makita service center.
Troubleshooting
If you encounter issues with your Makita circular saw, refer to the following common troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Saw does not start | Battery not charged or improperly installed; Tool switch malfunction | Charge battery, ensure proper installation; Contact service center |
| Reduced cutting performance | Dull or damaged blade; Incorrect cutting depth; Overloading the tool | Replace blade; Adjust cutting depth; Reduce feed rate |
| Excessive vibration or noise | Loose blade; Damaged blade; Internal component issue | Tighten blade arbor bolt; Replace blade; Contact service center |
| Kickback occurs frequently | Improper cutting technique; Dull blade; Workpiece not secured | Review operating instructions; Replace blade; Secure workpiece firmly |
AFT (Active Feedback sensing Technology):
The AFT system is designed to reduce kickback reaction by automatically shutting down the motor if the blade rotation is suddenly forced to stop. If the tool stops unexpectedly, check for obstructions, ensure the blade is sharp, and restart the tool.
