Question 1

What should we do if a power tool overheats after extended use?

Accepted Answer

Allow the tool to run without a load for 5–10 minutes to cool down efficiently.

Question 2

How should lithium batteries be stored?

Accepted Answer

Store lithium batteries in a cool, dry environment. Avoid exposing them to high temperatures. If unused for about two years, fully discharge the battery and then recharge it to one-third of its capacity. Avoid fully recharging.

Question 3

How can we identify when carbon brushes need replacement?

Accepted Answer

Regularly inspect carbon brushes and replace them promptly if sparking becomes frequent or unusually bright. Avoid waiting until the tool stops functioning, as worn brushes can damage sensitive components like the commutator.

Question 4

What is the correct mixing ratio for engine oil and fuel in 2-stroke engines?

Accepted Answer

Refer to the manual or machine body for the correct engine oil-to-fuel ratio for 2-stroke engines. For first-time use, mix a slightly higher ratio of oil for smoother startup.

Question 5

What should we do if the impact function of rotary hammers weakens over time?

Accepted Answer

Ensure the piston or cylinder is adequately greased. If the issue persists, inspect the piston O-ring for wear and replace it if necessary.

Question 6

Q6: The impact of rotary hammers and demolition breakers feels weak, despite applying a lot of pressure on it."

Accepted Answer

The principle of rotary hammer and demolition breaker works by the internal Impact hammer striking on the drill bit. When too much pressure is applied, the drill bit does not rebound in place and impact feels weakened. Adequate pressure should be applied to ensure proper functioning.
