The term "Annual Service" is one of those important sounding, but vague descriptions for getting work done on your equipment. But, have you ever wondered what it really means or what is involved? If so, you're in the right place and keep reading.
The first thing to keep in mind is an annual service varies quite a bit from one piece of equipment to another. Two stroke engines (like chainsaws and string trimmers) have different needs than four-stroke engines (like lawn mowers and motorcycles). For simplicity we will start with two-stroke powered equipment. A two-stroke engine is a relatively simple compared to a four-stroke. Generally speaking a two-stroke engine does not have a oil in the crankcase that needs to be changed since the lubricating oil is mixed with the gas. However, if your two stroke engine has a transmission, the transmission will have oil that needs to be changed periodically. The service parts on most of these engines include the spark plug, air filter and fuel filter (most of these fuel filters are located in the fuel tank). Many string trimmers have a transmission that needs to be greased. Of course carefully cleaning the body and engine is important to make sure the engine is getting appropriate air flow. Chainsaws in particular need to be cleaned since the combination of bar oil, saw dust and dirt tend to build-up and can lead to overheating. Four-stroke engines need similar servicing but generally have more fluids. On a typical four stroke engine the big thing to remember is making sure your engine oil is clean and at an appropriate level. Engine oil is one of those things that if changed regularly will keep your engine healthy for many years. Always refer to your owner's manual for specifics on your equipment. But a general rule of thumb for lawn equipment is engine oil should be changed every 50 hours and/or at least once a year even if you have less than 50 hours on the engine. Keep in mind, even if you don't use your equipment much, your oil will collect the condensation that forms on the inside of the engine. In addition to oil, the air filter, fuel filter and spark plugs should be serviced on a routine basis. On equipment with a hydro-static drive that is serviceable the transmission should be serviced approximately every 500 hours (again refer to your owner's manual for your specific machine). In addition to your engine, you need to consider a few other parts on your mower. blades should be checked at least once a year (more often depending on how much you use your mower). If your blades are not bent then they should be sharpened and balanced. If your blades have been sharpened several times or are bent then they should be replaced. Pay close attention the tips of the blades. If they are showing signs of cracks or chunks missing the blade should be replaced. Blade mandrels should be greased (if possible) and the bearings checked for play. Mandrel bearings wear out quicker than you think since they are spinning very fast and are exposed to water and abuse. If you catch a bearing failure early it is a fairly simple and inexpensive repair, but if left too long the entire mandrel will need to be replaced. Most riding mowers have at least two belts (more in some cases). Your mower has one belt that goes from the engine to the transmission and another that drives the mower deck. The mower deck belt is fairly easy to check, but the transmission belt can be hard to see and may require removing the mower deck to inspect. If your riding mower is having a hard time going up-hill it's probably time for a new belt. Your mower deck should also be cleaned (and scraped if needed). Compressed air is better to clean the excess grass and debris followed by water. If you don't have access to compressed air use your hands and pull out as much grass as you can before trying to use a hose. Water will only make the job harder. If equipped, remove the covers from the pulleys so you can get all the debris cleaned out. Leaving grass on the deck will lead to premature belt failure and rust. The bottom of the deck should be scraped and washed at least once a year. If you are cutting wet grass it should be done more often. All that wet grass sticks to the deck and promotes rust. Once your deck is clean, the deck level should be checked and adjusted if needed. Your engine and chassis should be cleaned and degreased. Excess dirt and grease on your engine will cause the engine to run hot and can lead to premature failure. It is also important to clean any excess grass and debris from under the hood and around the linkage for the mower deck. Grass can build up and cause premature belt failure, transmission slippage, etc. Finally, steering components should be cleaned and greased, tire pressures checked and tires inspected for cracks. Like any piece of machinery, regular maintenance is important to keep your equipment reliable for years. Feel free to give us a call if your equipment is ready for some attention!

I purchased my motorbike last year and now, everything’s a mess. I wasn’t able to have it checked since I bought it. This is the reason why buyers should take note of the things that must be done in order to take care of their vehicles. I agree that regular maintenance is very important. Now that I know this, I’ll be sure to be responsible and fix my bike. It’s never too late and I’ll list all your advice so I won’t be able to forget.
