How to add chain oil to a lithium chain saw?

Adding chain oil to a lithium chain saw is an important step to keep it running properly and extend its service life. Here is a detailed operation guide:

‌Step 1: Prepare tools and materials‌

‌1. Special chain oil‌: Use the lubricating oil recommended by the chain saw manufacturer. If there is no special oil, environmentally friendly mineral oil can be used as a substitute, but avoid using vegetable oil or waste oil.

‌2. Cleaning cloth‌: Used to wipe around the refueling port to prevent impurities from entering the tank.

3‌. Funnel or dropper‌: Convenient and accurate refueling to avoid oil spills.

‌Step 2: Locate the tank and add oil‌

‌1. Find the location of the tank‌: It is usually located near the chain guide on the chain saw body, marked with "OIL" or an oil drop icon.

Some models require the removal of the guide guard or side cover to see the oil filling port (refer to the diagram in the manual).

‌2. Open the tank cap‌: Unlock the tank cap by turning it counterclockwise or pressing it, and be careful to avoid dust from falling in.

‌3. Inject chain oil: Slowly pour the oil to 80%-90% of the tank capacity, leaving room for expansion. If the tank has a transparent window, the oil level should be at the upper limit (MAX) mark.

‌Step 3: Check the working status of the lubrication system‌

‌1. Manual oil supply test: When the chain saw is not started, lift the guide bar and gently pull the chain to observe whether there is oil leakage at the end of the guide bar. If not, the oil circuit may be blocked and needs to be cleaned.

‌2. Operation test‌: Start the chain saw, idle at high speed for 10-15 seconds, and aim the tip of the guide bar at the white paper. Under normal circumstances, you should see oil droplets splashing or forming oil lines. If there is no oil stain, check whether the oil pump is faulty or adjust the oil supply.

‌Step 4: Maintenance and precautions‌

‌1. Refueling frequency‌: Refill oil every 1-2 hours of use, or add it in time according to the tank capacity. The oil tank should be emptied before long-term storage to prevent oil oxidation from clogging the oil circuit.

‌2. Environmental protection‌: Waste oil needs to be recycled and cannot be dumped at will to pollute the environment.

‌3. Common problems‌:

‌Oil leakage‌: Check whether the oil tank seal is aging and whether the oil guide pipe is broken.

‌Insufficient lubrication‌: Clean the oil hole of the guide plate to ensure that the oil path is unobstructed; low-temperature chain oil can be used in cold weather.
