How to Build a Stihl 180 Saw

Stihl MS 180. a reliable and unpretentious tool, but sometimes requiring repair, like any equipment. In this article, we will consider how the Stihl ms 180 chainsaw is disassembled, which is necessary in the event of an overhaul of the engine.

Preparatory stage

Repair of any equipment should begin with the preparatory phase, and the Stihl 180 saw is no exception. At the preparatory stage, before dismantling the Stihl 180 chainsaw, it is necessary to remove the side cover, chain and tire from the chainsaw. Next, with the help of a compressor and a brush, you need to clean the chainsaw from dirt, sawdust, oil drips and other things.

Particular attention when cleaning the saw should be given to the place where the chain sprocket of the chainsaw is located, because this is the most polluted area.

In places of large accumulation of oil, you can rinse with clean gasoline.

Handle removal

Direct disassembly of the Stihl 180, begins with the removal of the handle, which is attached to the body of the chainsaw using three rubber shock absorbers. To remove, it is necessary to remove the plastic plugs from the inner cavity of the shock absorbers, and then using a powerful screwdriver, squeeze out the upper shock absorber first, then the one that is closer to the rear handle.

A gas trigger is installed in the rear of the handle, which is connected to the carburetor through a wire rod, in order to disconnect the rod from the gas trigger, two screws must be loosened and the handle disassembled.

When the handle remains on one shock absorber, it is necessary to unscrew the chainsaw body from the inside of the handle and breaking it to the side, remove the body from the last rubber band.

Starter Removal

At the next stage, the upper housing cover is removed and 4 starter mounting screws are untwisted, after which it is necessary to remove the oil tank and fuel barrel covers. The starter is removed quite simply and no problems should arise.

After removing the starter, the opened internal cavity of the chainsaw needs to be cleaned, because usually on the body under the starter there is a large number of compacted small sawdust.

Flywheel removal

The Stihl 180 chainsaw flywheel is twisted with great effort, so to remove it you will need a head with a metal knob. The nut holding the flywheel is unscrewed by 13.

To lock the crankshaft from turning, you need to unscrew the candle and install the piston stopper through the spark plug hole, if it is not there, you can use the old cord from the starter, with the components attached to it and immersed in the cylinder through the spark plug hole.

It is strictly forbidden to keep the flywheel from turning by installing a power screwdriver and other tools between its ribs and the body, with this method of locking from turning, the flywheel blades are not able to withstand loads and break off.

After the piston in the cylinder is blocked, you can unscrew the flywheel nut. The thread in the nut is normal, so you need to twist to the left side. After loosening the nut, it is not necessary to completely remove it, it is enough to unscrew it until its upper edge is equal to the tip of the shaft, after which the drift of soft metal is installed on the nut and a sharp blow is made to it. Thus, the flywheel jumps off the shaft from a sharp impact and can be easily removed without the need for additional tools.

At the same time, inspect the oil lines and the connection density with the fittings. Be sure to clean the filter at the oil supply. If there is little mechanical damage to the hoses, the density can be returned using sealant.

The carburetor makes itself felt by the difficulty when starting the saw, the running tool does not develop, it stalls when throttling. As a prerequisite, you will like the wear of the cuff on the piston, during which it draws in air during discharge. During the repair, the carburetor is removed and gets to the cuff on the accelerator, disassembling the assembly in the sequence:

• remove the cover with the membrane by unscrewing the screw;
• remove the snap ring;
• disconnect the air damper, remove the throttle;
• pull out the accelerator with a spring;
• change the tiny piston with the cuff and assemble the carburetor in the reverse sequence.

Problems will be associated with the ignition system. After checking the performance of the candles and cleaning the soot, adjust the carburetor, the feed system and clean the injections. The carburetor is a complex unit and the operation of the chassis depends on its option. If there is no conviction and skill, it is better to use the services of a specialist.

Features of saw chains

The working mechanism of the saw is a chain. Saw chains are manufactured using a special technology:

1. The cutting element is made of high carbon steel, and the use of chromium plating or applying a victorious layer to the cutter. The more difficult the development of production, the higher the price of the chain.
2. The hinge holes are ground to reduce friction and extend service life.
3. Rivets are used only hardened by a special technology.
4. Marks are applied to the teeth, according to which wear is determined and to perform uniform sharpening.
5. After connecting the links in a chain, the product is stretched to ensure dimensional stability during operation.

The intelligent automatic chain lubrication system extends its life. New saws required> be selected according to the characteristic indicated in the operating manual Stihl chainsaws 180.

You should know that chains with victorious surfacing are 3-5 times more expensive than ordinary ones, however it is unrealistic to sharpen them yourself by repairing a Stihl 180 chainsaw. Employees of the Ministry of Emergency Situations often use such inventory.

For a long maintenance-free period, use the oil recommended by the tool manufacturer. A special mineral composition is used to prevent chain grinding. It is unacceptable to use oil created for additives in gasoline for saws Stihl.

It is often asked how longitudinal cuts can be made with a Stihl 180 saw. The power of the saw allows you to work on cutting wood only across the fibers.

The cost of a Stihl MS 180 chainsaw is significantly different. The cheapest basic model of an ordinary complete set. The price of the device depends on the country of manufacture. German, in other words, a South American product is more expensive than Chinese for well-known reasons.
