Öryggisupplýsingar
Fylgið alltaf grunnöryggisráðstöfunum til að draga úr hættu á eldsvoða, raflosti og meiðslum á fólki. Geymið þessa leiðbeiningarhandbók til síðari viðmiðunar.
- Öryggi vinnusvæðis: Haldið vinnusvæðinu hreinu og vel upplýstu. Rúm eða dimm svæði geta leitt til slysa. Notið ekki rafmagnsverkfæri í sprengifimu andrúmslofti, svo sem þar sem eldfimir vökvar, lofttegundir eða ryk eru til staðar.
- Rafmagnsöryggi: Klóar á rafmagnsverkfærum verða að passa við innstunguna. Breytið aldrei klónum á nokkurn hátt. Forðist snertingu við jarðtengda fleti.
- Persónulegt öryggi: Always wear eye protection, hearing protection, and appropriate respiratory protection. Use safety footwear and gloves when necessary. Stay alert, watch what you are doing, and use common sense when operating a power tool.
- Notkun verkfæra og umhirða: Ekki þvinga rafmagnsverkfærið. Notið rétt rafmagnsverkfæri fyrir notkunina. Aftengdu rafhlöðuna frá rafmagnsverkfærinu áður en þú gerir stillingar, skiptir um fylgihluti eða geymir rafmagnsverkfæri.
- Öryggi rafhlöðu: Use only genuine Makita batteries. Using non-genuine batteries can lead to fire, personal injury, or property damage, and voids the product warranty.

2. Festing hliðarhandfangsins
Hægt er að skrúfa hliðarhandfangið í hvora hlið gírhússins sem er fyrir vinstri eða hægri hönd. Gangið úr skugga um að það sé vel hert fyrir notkun.

Mynd 4: Hlið view of the grinder with the auxiliary side handle attached. The handle provides additional control and stability during operation.
3. Stilling hjólhlífarinnar
The tool features a toolless wheel cover (part number 123145-8) for quick adjustment. Loosen the clamp lever, rotate the guard to the desired position to protect against sparks and debris, and then tighten the lever firmly.
4. Installing Grinding/Cutting Wheels
To install a wheel, first ensure the tool is off and the battery is removed. Press the spindle lock button to prevent the spindle from rotating. Place the inner flange onto the spindle, then position the grinding or cutting wheel (e.g., 5" Depressed Centre Wheel D-20797) onto the inner flange.

2. Variable Speed Adjustment
The variable speed dial allows for RPM adjustment from 3,000 to 8,500. Rotate the dial to select the appropriate speed for your application. Lower speeds are suitable for polishing or delicate work, while higher speeds are for aggressive grinding or cutting.

Figure 8: Detail of the variable speed dial, allowing users to select RPM settings from 1 to 5.

Figure 9: A chart on the tool body correlating dial settings (1-5) with their respective RPM ranges, from 3,000 to 8,500 min⁻¹.
3. Active Feedback Sensing Technology (AFT) and Automatic Torque Drive Technology (ADT)
This tool incorporates advanced safety and performance features:
- Virk endurgjöfarskynjunartækni (AFT): Automatically shuts down the tool if there is a sudden drop in rotation speed, such as during a kick-back event, enhancing user safety.
- Sjálfvirk togkraftsdrifstækni (ADT): Adjusts speed and torque automatically during operation for optimal performance based on the load, ensuring efficient material removal.
4. Rafmagnsbremsa
The integrated electric brake stops the grinding or cut-off wheel in 2 seconds or less after the paddle switch is released, contributing to increased productivity and safety.
5. Vísir fyrir hleðslu rafhlöðu
The tool features a battery charge indicator to monitor the remaining battery life. Refer to the indicator lights to determine when recharging is necessary.

Viðhald
1. Þrif
Regularly clean the tool's ventilation openings to prevent overheating. Use a soft cloth to wipe down the exterior. Do not use harsh chemicals or abrasive cleaners.
2. Brushless Motor
The brushless motor design eliminates the need for carbon brush replacement, reducing maintenance requirements and increasing motor lifespan.
3. Umhirða rafhlöðu
Store batteries in a cool, dry place away from direct sunlight. Do not expose batteries to water or extreme temperatures. Follow the charging instructions provided with your Makita charger.
4. eXtreme Protection Technology (XPT)
The tool features XPT, which provides enhanced protection against dust, debris, and liquids. While XPT improves durability, it does not make the tool waterproof. Avoid exposing the tool to excessive moisture.

- Tólið ræsist ekki: Ensure the battery is fully charged and properly inserted. Check that the paddle switch lock-off lever is fully engaged before depressing the paddle switch.
- Tool Stops During Operation: This may indicate activation of the Active Feedback Sensing Technology (AFT) due to a sudden drop in rotation speed (e.g., kick-back). Release the paddle switch, clear any obstruction, and restart the tool. If the issue persists, check the wheel for damage or excessive wear.
- Minni árangur: Ensure the battery is fully charged. Check the grinding/cutting wheel for wear or damage and replace if necessary. Verify that the correct speed setting is selected for the application.
- Of mikill titringur: Check if the grinding wheel is properly installed and balanced. Replace any damaged or unbalanced wheels. Ensure the side handle is securely tightened.
