The motorized chain saw is a type of chainsaw and the only domestically produced diamond chain saw. It has the characteristics of light weight, convenient use, wide operating range, pollution-free, and high safety. It can achieve the cutting of coal seams, rocks, concrete, reinforced concrete, pipelines, bricks, stones, and other stones and wood. Its narrow cutting arm can penetrate blind or through holes up to 500 millimeters in one molding operation, and is not limited in size. Let's learn how to use a motorized chain saw together.

1、 Performance parameters of motorized chain saws

Purpose: Mainly used for dismantling wooden components at rescue sites.

Composition: It consists of the engine (including switch, start pull rope, damper, throttle, throttle lock, pressure reducing valve), chain saw, operating handle, brake handle, fuel tank, etc.

Performance: Single cylinder two-stroke air-cooled engine, with a fuel ratio of (50:1) gasoline to engine oil, with a speed of 12500 rpm and a maximum cutting length of 500mm.

Features:

1. Easy to use: This machine adopts a single person portable operation and is lightweight.

2. Wide scope of work: capable of cutting coal seams, rocks, concrete, reinforced concrete, pipelines, bricks, stones, and other stones, as well as wood. Its narrow cutting arm can penetrate blind or through holes up to 500mm in depth for one-time forming operations, and is not limited in size. The minimum cutting square hole is: long × Width=120 × 120 millimeters.

3. Non pollution: Wet cutting is adopted, with water flowing out of the saw board at high speed and directly reaching the saw chain and cutting objects, without any dust generation.

4. High safety: The host is equipped with multiple protective devices to prevent personal injury, ensuring that any malfunction of the machine can prevent personal injury. When the flushing water pressure is lower than 0.2MPa, the chain saw will automatically stop working to prevent high temperatures and sparks.

5. High technological content: The main driving components adopt the best international high-speed motors, which operate smoothly and efficiently; The saw chain cutter head adopts diamond sintering technology and laser welding, with long service life, high cutting speed and low price.

6. The operation of the host conforms to ergonomics: the machine is equipped with a clever assist frame, which automatically converts the operator's forward thrust into the downward cutting force of the saw chain, reducing the operator's labor intensity.

2、 Method of use for motorized chain saws

1. Before use, check the safety technology status.

2. When operating, wear personal protective equipment such as helmets, safety glasses, gloves, work shoes, etc.

3. During cutting, it is not allowed to stand up, wedge or block the cutting wheel.

4. In practical operation, both hands should tightly grasp the front and rear handles, buckle the accelerator pedal, and rotate the chain at high speed. The serrated cutting blade must be perpendicular to the cutting section of the object being cut. If there is abnormal vibration during use, the machine should be stopped immediately to investigate the original situation, and can only be used after troubleshooting.

5. Under no load, it is strictly prohibited for the machine to run at high speed, and the engine must not rotate at high speed for a long time to prevent the saw blade from flying out and injuring people.

6. Silencers are strictly prohibited from being touched due to high temperatures during and after use.

7. The tightness of the chain and chain plate should not be too tight or too loose.

8. When using a chain saw, pay attention to the rebound effect of the guide plate.

9. Immediately clean, replenish fuel, and replace the chain saw blade after use.
