It's frustrating to have your lawnmower cable suddenly cut, and you can't use your mower even though the engine's perfectly fine.
Obviously, the first option that comes into mind is not replacing the unit but fixing the mower cable.
And, yes, you definitely can fix it - but only if you're sure that you know how to do it properly.
Haphazardly connecting wires, especially for outdoor machines like lawn mowers, could be a recipe for disastrous irreparable damage for the machine and you.
Outdoor wires have to be wholly waterproof, or else you risk short circuit, wire corrosion, water damage, or worse, electrocution. That's why simply connecting the cut wire won't do it.
This method is quick and easy. No hassle involved in fiddling with a power outlet/source.
It is also the cheapest. You can buy crimping kits online for really low prices.
1. Expose some of the wires on both wires you're connecting with a plier or wire stripper. Make sure to only expose based on the size and sort of connector you have. Take off no more than 1/4 inch of the insulation, to be sure.
2. Insert and align the exposed portion of wire in the cable you want to connect inside the suitable connector of your choice.
3. Crimp right on the exposed wire tightly with the crimping tool. You can also crimp more of the connector, to be sure.
4. Do a tug test on the connected wires. If crimped correctly, they shouldn't slide off.
5. If using a heat shrink connector, apply heat to shrink and seal your connection. If using a connector that snaps and locks, make sure they're connected properly.
6. This is optional, but you can wrap the connection again with some electrical tape for an added layer of protection.
Notes:
If you don't have a crimping tool you can seal the connectors by hammering them. Although, this is not ideal.
If you don't have a heat gun, you can use a lighter. But, that increases the risk of burning the insulation, so you have to be careful using it.
Soldering is slightly more advanced, but it is the most secure, durable, and efficient wire fusion technique for this power cable repair and any metal wires, in general. However, this could be expensive if you don't have the materials already available.
1. Expose half an inch to 3/4 inch of your wires with a plier or wire stripper.
2. Slide the heat shrink tube on one of the wires you're connecting.
3. Fan out the strands of your wire segments and then interweave them together. You can also cross the wires and twist them together.
4. Make sure there are no wire strands sticking out. This could puncture and poke a hole in the heat shrink tube and make it not waterproof.
5. Heat up your solder iron. Then, heat your connected wires with the tip of your heated solder iron. Tap the solder on the heated wire and solder iron tip to melt it into the wire. Slide and scatter the melted solder across the exposed wired
6. Let the solder cool off. Once it does, slide the heat shrink tube to cover the soldered wires and heat it up until it tightly wraps around the wire.
7. This is optional, but you can wrap the connection again with some electrical tape for an added layer of protection.
Notes:
If you don't have a heat gun, you can use a lighter. But, that increases the risk of burning the insulation, so you have to be careful using it.
You can repair your cut mower cable and even add an extension cable if you know how to.
Make sure to use waterproofing or weatherproofing methods and materials to ensure safety.
Aside from water damage, make sure that the extended cable is safe from tugging and further damage to your electronics.
As with anything that involves electricity which is potentially dangerous, you should only attempt to fix your mower cable on your own if you're confident that you can make it weatherproof and tug proof.
You can do the options provided above as a temporary fix so you can mow your lawn if you need to.
The best course of action is still getting help from a professional.
Seeing smoke coming out of an engine is always scary, especially if it's from a potentially dangerous machine such as a lawn mower.
Lawn mowers shouldn't smoke when you start them up. A lawn mower should be able to run without smoking.
Was your lawn mower working just fine, and then suddenly started smoking?
Don't know what it means and what to do?
Fret not! We're here for you.
Knowing the cause of the smoke will teach us how to fix it. The color of lawn mower smoke indicates the problem.
Lawn mowers emit different colors of smoke. The smoke from your lawn mower could be white, blue, or black.
White is the most common color in lawn mower smoke. It could also appear blue.
The smoke should disappear by itself if you run the lawn mower for about 15 minutes. If it doesn't disappear after running the lawn mower for around 15 minutes, then you should check out the manual for your lawn mower.
White or blue smoke could mean that the engine needs repair. You need to turn off your lawn mower and take it apart to check if there's something wrong with it.
Typically, white or blue smoke indicates the following issues:
Lawn mowers should always use oil, even if it's just a little bit. Oil helps prevent damage to the engine.
Tipping the mower on the side is dangerous because oil moves into the engine.
This smoke could be caused by burning oil.
If you do, the oil moves from the crankcase to the cylinder. It may even cause a leak.
Always put your mower upright, even when stored. You should check the oil in the crankcase. You can fix this issue by just letting the engine run. After a while, the smoke will dissipate.
Lawn mowers should be filled with about half a quart (0.5l) of oil. Overfilling causes problems because the engine doesn't get enough oil to run properly. Splash lubrication systems work better when there is less than half a quart (0.5l) of oil in the tank. Always check your manual about the right oil to use for your unit.
Overfilled lawn mower oil reservoir can cause your engine to burn oil.
Overfilling the crankcase can cause an engine to seize up. This should never happen because it could lead to a fire. Oil spills can damage your lawn mower. You should always check the oil level before using your mower. Drain excess oil and check and add more if needed before using.
Depending on your mower type, you may need an oil extractor.
If the oil smells like gas, you should stop the mower and check the carburetor. You want to fix the carburetor and change the oil before using it again.
Adding proper oil and fixing the problem with the carburetor before you run the engine. Otherwise, you'll damage the engine.
Head Gaskets are important parts of engines. They're made out of metal and graphite. They seal the combustion chamber. They're used to prevent oil leaks.
Oil leaks, high pressures in the crankcase, and a strange noise are some common symptoms of head gasket issues. White smoke could mean that there is a leak or something wrong with the engine.
Check if you've put oil in the gas tank by mistake. It's a common mistake.
After a while, the remaining oil will clear out, and so will the white smoke.
Just like a car engine, you should check your lawn mower regularly. Make sure that everything works properly. Sometimes, you might have to replace certain parts such as crankcase breather, head gasket, cylinder head, piston rings, etc.
You may need a will need a compression test. This should be done by an experienced mechanic.
Smoking may also be caused by carbon buildup in your spark plug.
Ensure to also double-check the gap in the plug according to the unit manual. You can always just replace it. Make sure you don't use the wrong plug type.
A black smoke issue in mowers typically indicates carburetor and fuel systems problems.
Black smoke coming out of a mower means that the engine is overheating. It may be due to a clogged air filter.
To check, remove the air filters and start the engine. If you don't see any smoke, then it's the problem.
You can clean the air filter and remove dirt and other particles.
But, replacing the air filter is more effective. After you clean the air filter or replace it, start your lawn mower and let it go for a few minutes to check if the problem has been solved.
Black lawn mower smoke could mean your carburetor isn't working right. Black smoke can be caused by an unsuitable fuel-to-air mixture. There may be more gasoline than there should be.
You can also change your entire carburetor after confirming that it's failing.
White smoke could be just normal when starting up a new lawn mower.
Blue or black smoke indicates a problem.
To summarize, you can troubleshoot the most common lawn mower problems by:
1. Checking the mower for oil issues
2. Checking the air filter
3. Checking the angle which you're mowing
4. Checking the mower engine and its parts if it needs cleaning, adjusting, or replacing.
If you want to fix the issues yourself, always refer to your unit's manual or, better yet, consult a professional at your trusted lawn mower repair shop.
