Metabo BKH 450 Plus-5 Operating Instructions

To change the blade, first ensure the saw is unplugged. Use the blade wrench provided to loosen the arbor nut. Remove the old blade and replace it with the new one, making sure the teeth point in the correct direction. Tighten the arbor nut securely.
To align the fence, first ensure the saw is off. Loosen the fence adjustment bolts and use a square to align the fence parallel to the blade. Tighten the bolts once the alignment is correct.
If the motor does not start, check the power supply and ensure the saw is plugged in. Inspect the power cord for damage. Check the fuse or circuit breaker. If the problem persists, consult a professional technician.
Regular maintenance includes cleaning the sawdust from the machine, lubricating moving parts, checking the blade for sharpness, and inspecting the power cord and plug for wear.
To adjust the cutting depth, loosen the depth adjustment lever, set the blade to the desired depth, and then tighten the lever to lock the blade in place.
Always wear safety goggles, keep hands clear of the blade, and ensure the workpiece is secured. Additionally, check that all safety guards are in place before operating the saw.
To improve accuracy, ensure the saw is properly calibrated, use a sharp blade, and take your time to make precise measurements and alignments before cutting.
If the blade overheats, stop the saw and allow it to cool. Check for dullness or pitch buildup on the blade, and ensure you are not forcing the cut or using the wrong blade type for the material.
The saw is primarily designed for wood. If you need to cut metal, use a blade specifically designed for metal cutting and ensure the saw has the appropriate speed settings and safety measures.
Store the saw in a dry, clean area. Cover it to protect from dust and debris, and ensure the blade is retracted or removed to prevent accidental contact.
