Safety comes first when using an electric chain saw. Here is a detailed operating guide to help you use an electric chain saw correctly and safely:

### ** I. Preparation before use **

1. ** Check the state of the electric chain saw **

- Make sure the chain is sharp, undamaged and well lubricated (the chain oil box needs to be filled).

- Check the chain tension: gently lift the middle of the chain with your fingers, which should be able to pull up about 3-5 mm (too loose or too tight need to be adjusted).

- Ensure that the power cable or battery is fully charged (without damage).

2. ** Wear safety gear **

- Cut-resistant gloves, goggles, non-slip shoes, long-sleeved pants, helmet (if required).

- Avoid loose clothing or long hair near the chain.

3. ** Clean the work area **

- Remove obstacles on the ground and ensure standing smoothly, away from other people and animals.

### ** Two, starting and operating steps **

1. ** Fixed electric chain saw **

- Place the saw on the ground smoothly, with the chain not in contact with any object.

- Hold the rear handle with one hand and put your foot on the front guard plate (some models need to unlock the safety switch first).

2. ** Start power supply **

- Plug-in: Connect the power supply to ensure that the line will not trip.

- Battery: Insert a fully charged battery and press the power switch.

3. ** Start cutting **

- ** Hold with both hands ** : hold the front handle with the left hand, hold the back handle with the right hand, and stand firm.

- ** Lightly touch the throttle ** : Slowly pull the trigger until the chain is running at full speed before touching the wood.

- ** Cutting Tips ** :

- Cut with the bottom half of the chain **, avoiding the tip (anti-rebound).

- Cut along the grain of wood, do not twist the chain forcibly.

- When cutting large wood, make grooves to prevent clipping saws.

### ** III. Safety precautions **

1. ** Beware of kickbacks **

- Rebound is a dangerous situation in which the chain suddenly bounces towards the operator, mostly caused by the chain tip hitting a hard object or improper operation.

- Avoid cutting with the front end of the chain and always keep your body behind the side of the chain.

2. ** Power off and rest **

- Release the trigger immediately when pausing, turn off the power.

- Allow the motor to cool after 15-20 minutes of continuous use.

3. ** Emergency handling **

- If you have a card saw, power off first and then slowly pry open the wood, do not force the saw.

### ** Fourth, maintenance after use **

1. ** Clean **

- Remove wood chips and resins from chains and guides.

2. ** Lubrication and inspection **

- Add chain oil and check the wear degree of the chain (replace it regularly).

3. ** Store **

- Disconnect power/Remove battery, store in dry place, chain with sheath.

### ** Five, common mistakes **

- ❌ One-handed or high cut.

- ❌ Use in humid environments or on rainy days (risk of electric shock).

- ❌ Using dull chain or neglecting lubrication (resulting in motor overload).

** Tip ** : First time use is recommended to practice cutting scrap wood under professional guidance. Electric chainsaws are suitable for light work (such as pruning branches, cutting small wood), and gasoline saws are recommended for heavy duty tasks. Safety is always the first!
