After maintenance (especially after contact with engine oil and coolant), it is necessary to wipe the oil on the tool surface with a rag.
Metal tools such as sleeves and wrenches can be coated with a small amount of antirust oil.
Tools such as sleeves and wrenches are made of high hardness materials such as alloy and S2 tool steel.
The tool is fixed and protected, closely fitting the contour of the tool.
When the vehicle runs on the bumpy road, the tools will not shake and collide, so as to avoid mutual friction and damage of the tools, and at the same time, to prevent the inconvenience caused by tool displacement when taking tools.
