What are the tips for using and maintaining garden tools?

In the use of garden tools, various problems will inevitably occur, and we can easily eliminate them with some tips.
Check for cracks: Once the parts on the machine are cracked, they must not be used reluctantly. But how to judge whether the part has cracks and where is the crack? Soak the suspicious part in kerosene for 30 minutes, take it out and wipe the surface dry, and smear a layer of chalk dust on the surface. After a period of time, the chalk dust absorbs the kerosene from the cracks, causing the cracked area to change. Black, the cracked part of the part can be detected.
Ingenious tire installation: first remove the rust on the rim, apply a thin layer of talcum powder between the inner and outer tires, then lay the rim flat and put on the outer tire. Use a pedal or a crowbar to pry one side of the tire into the rim, insert the inner tube, and fix the inflation valve in the rim inflation valve hole with a wire, and finally install the other side of the tire. Starting from the corresponding position of the inflation valve, use a crowbar to pry a part of the tire into the rim, and then gradually install it from the inflation valve to both sides. At the same time, step on the tread opposite to the inflation valve with your foot. The traveller part of the tire is gradually fitted into the rim.
Ingenious installation of oil seal: When installing an oil seal on the crankshaft, the inner end face of the seal is likely to be twisted, causing oil leakage. Roll a piece of clean thin hard paper into a flared roll, put the roll on the shaft, put the small end of the roll on the shaft end, put the oil seal on the small end of the roll, and gently apply the oil seal Screw on the shaft, the direction of rotation is consistent with the direction of the reel. When the oil seal is in place, slowly exit the reel.
Ingeniously check the cable: the cable used for the disconnected water pump is prone to disconnection due to repeated folding and twisting in use. Use a 220V power plug to connect a 220V, 15W bulb in series to one of its power cords, and connect the two power cords to both ends of a core wire in the cable. After connecting the power source, the bulb lights up to indicate the line is connected. Otherwise, this core wire is broken. At this time, hold the cable with both hands and squeeze it in the middle section by section. If the light is on, it means the wire is broken. Disconnect the power supply, cut the rubber sleeve with a knife, connect the broken wire, and then wrap it with insulating tape.
