2. Sikkerhedsinstruktioner
Always observe the following basic safety precautions to reduce the risk of fire, electric shock, and personal injury.
Generelle sikkerhedsadvarsler for elværktøj
- Sikkerhed på arbejdsområdet: Hold dit arbejdsområde rent og godt oplyst. Rodede eller mørke områder indbyder til ulykker. Brug ikke elværktøj i eksplosive atmosfærer, f.eks. i nærheden af brandfarlige væsker, gasser eller støv. Elværktøj skaber gnister, der kan antænde støv eller dampe.
- Elektrisk sikkerhed: Elværktøjsstik skal passe til stikkontakten. Modificer aldrig stikket på nogen måde. Brug ikke adapterstik med jordet (jordet) elværktøj. Umodificerede stik og matchende stikkontakter reducerer risikoen for elektrisk stød.
- Personlig sikkerhed: Vær opmærksom, hold øje med, hvad du laver, og brug din sunde fornuft, når du betjener et elværktøj. Brug ikke elværktøj, mens du er træt eller påvirket af stoffer, alkohol eller medicin. Et øjebliks uopmærksomhed under betjening af elværktøj kan resultere i alvorlig personskade.
- Brug og pleje af værktøj: Tving ikke elværktøjet. Brug det korrekte elværktøj til din opgave. Det korrekte elværktøj vil udføre arbejdet bedre og mere sikkert med den hastighed, det er designet til. Tag stikket ud af strømkilden, og/eller fjern batteriet, hvis det kan tages af, fra elværktøjet, før du foretager justeringer, skifter tilbehør eller opbevarer elværktøj.
- Service: Få dit elværktøj efterset af en kvalificeret reparatør, der kun bruger identiske reservedele. Dette vil sikre, at elværktøjets sikkerhed opretholdes.
Specifikke sikkerhedsadvarsler for rundsave
- Hold værktøjet i de isolerede gribeflader when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Contact with a "live" wire will also make exposed metal parts of the power tool "live" and could give the operator an electric shock.
- Brug clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.
- Bær øjenværn. Bær altid sikkerhedsbriller eller sikkerhedsbriller med sideskærme.
- Hold hænderne væk fra skæreområdet og klingen. Hold din anden hånd på hjælpehåndtaget eller motorhuset. Hvis begge hænder holder saven, kan de ikke skæres af klingen.
- Ræk ikke ind under arbejdsemnet. Beskyttelsen kan ikke beskytte dig mod klingen under emnet.
- Tilpas skæredybden til tykkelsen af emnet. Mindre end en hel tand på klingen skal være synlig under emnet.
- Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform. It is important to support the workpiece properly to minimize body exposure, blade binding, or loss of control.

5. Opsætning
5.1 Attaching/Changing the Saw Blade
- Sørg for, at saven er frakoblet strømkilden.
- Tryk og hold spindellåseknappen nede.
- Using the provided hex key, loosen the blade retaining screw by turning it counter-clockwise.
- Carefully lift the lower blade guard and remove the old blade.
- Place the new blade onto the spindle, ensuring the teeth are pointing in the direction of rotation (indicated by an arrow on the saw and blade).
- Tighten the blade retaining screw clockwise while holding the spindle lock button. Do not overtighten.
- Release the spindle lock button and check that the blade is securely fastened and rotates freely.
5.2 Assembling and Securing Guide Rails
The guide rails provide precise, straight cuts, especially for longer workpieces.
- Connect the two guide rail sections using the provided connector piece. Ensure they are firmly joined and aligned.
- Place the assembled guide rail on your workpiece, aligning it with your desired cutting line.
- Brug den medfølgende clamps to secure the guide rail to the workpiece or workbench. Ensure the rail is stable and will not shift during cutting.
- Slide the circular saw onto the guide rail. The base plate of the saw is designed to fit snugly onto the rail.

5.3 Tilslutning af støvudsugning
For a cleaner work environment and improved visibility of the cutting line, connect a vacuum cleaner to the dust extraction port.
- Find støvudsugningsåbningen på saven.
- Attach a suitable vacuum hose to the port. Ensure a secure connection to prevent dust leakage.

6. Betjening
6.1 Indstilling af skæredybde
The cutting depth can be adjusted up to a maximum of 22 mm.
- Løsn dybdejusteringshåndtaget/knappen.
- Move the base plate up or down to achieve the desired cutting depth. Ensure that the blade extends slightly below the workpiece.
- Tighten the depth adjustment lever/knob securely.
6.2 Justering af variabel hastighed
This saw features variable speed control, allowing you to optimize the cutting speed for different materials.
- Locate the variable speed control dial.
- Turn the dial to select the appropriate speed for your material. Lower speeds are generally suitable for harder materials or when more control is needed, while higher speeds are for softer materials.
6.3 Lav et snit
- Sørg for, at arbejdsemnet er sikkert klamped and the guide rail (if used) is properly aligned and secured.
- Sæt saven i en passende stikkontakt.
- Hold saven fast med begge hænder, den ene på hovedhåndtaget og den anden på ekstrahåndtaget.
- Press the lock-off button, then press the on/off switch to start the saw. Allow the blade to reach full speed before beginning the cut.
- Slowly and steadily guide the saw along the cutting line. Do not force the saw; let the blade do the work. Maintain constant pressure and feed rate.
- Once the cut is complete, release the on/off switch and allow the blade to stop completely before lifting the saw from the workpiece.

7. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer din rundsavs lange levetid og optimale ydeevne.
- Rensning: After each use, unplug the tool and clean it with a soft cloth. Remove any dust or debris from the ventilation openings and around the blade guard. Do not use solvents or abrasive cleaners.
- Bladinspektion: Regularly inspect the saw blade for sharpness and damage. A dull or damaged blade can cause kickback and reduce cutting efficiency. Replace blades as necessary.
- Kulbørster: The motor is equipped with carbon brushes. If the motor sparks excessively or the tool stops working, the carbon brushes may need replacement. This should be done by a qualified technician.
