Limit cutting material to wood only
Never use a mini chainsaw for cutting any non-wood material, including plastic, masonry, or metal. Never cut a tree or branch with a diameter wider than the length of the mini chainsaw’s guide bar.
Tension the Chain Properly
Make sure that the chain is properly tensioned on the guide bar. A loose chain may whip free or draw materials into it. A tight chain may not move at all or have a higher risk of breaking down during heavy-duty operations.
A thumb of rule: pull the chain to check the tightness of fitting. Let the upper side of the down chain bite loosely with the guide bar but leave no clearance when you pull the down chain with force.
Kickback results from the tip of the moving chainsaw being allowed to come into contact awkwardly with an object. The tip may bounce wildly backward and injure the worker.
The guide bar of the mini chainsaw should be 1-2 inches longer than the diameter of what you need to cut. Chainsaws with a top flap or low kickback have a lower risk of kickback incurred injury.
Sharpen the chain regularly
There’s no hard-and-fast rule on how often you need to sharpen your chainsaw, but many experts recommend doing it every time you need to refuel the tool.
Follow the dressing code
Do not wear loose-fitting clothing, dangling jewelry, or anything else that could become caught in the chain of the saw.
Avoid Touching the Chain, Even When Stationary
Chainsaws’ chains are very sharp. Even when the chain is not moving, it can severely lacerate the skin. Be sure to keep the cover on the saw when not in use or remove the battery so the machine doesn’t start at all.
Lubricate the chain in a timely manner
The oil lubricates the bar and chain, preventing premature wear and possible derailing of the chain.
After the oil is applied, run the chainsaw for a few seconds until it is spread evenly onto the chain. While manual oiling may be a little tricky to handle, there are auto oiling options that distribute a consistent, steady flow of oil onto the chain. Check the oil tank to keep track of the oil level for a timely refill.
