Chainsaw Stihl MS 180 - features of operation and maintenance

The Stihl MS 180 chainsaw is used to prepare a supply of firewood in private homes and small farms, improve garden plots, crown shrubs; it can be used to clear the site and perform a variety of work of varying levels of complexity, including felling trees and sawing wood. This is truly a multifunctional device. In addition, you can use different attachments for repair and construction work.

Device Features

The design of the Shtil 180 chainsaw is simple; the developers have made a lot of effort to ensure that the household appliance has all the advantages of a professional model and is accessible to beginners in this field. Design features allow the device to be used by users with different levels of training:

• The carburetor circuit of the Shtil 180 chainsaw makes it possible to adjust the unit yourself using a specially designed screw.
• The design allows the use of tires of different sizes. The usual tire for the Shtil 180 chainsaw provided by the manufacturer is fourteen inches; if necessary, you can install a model of sixteen inches. This feature makes it possible to significantly increase productivity.
• A two-stroke single-cylinder engine runs on a mixture consisting of only two components - gasoline and oil, the choice of which must be taken as responsibly as possible, since the quality and service life directly depend on this.
• To start the engine you will need to pull the starter wire.

Technologies used

When creating the saw, several technologies were used that make its use more comfortable and increase its service life:

1. Compensator valve . There is a special valve located in the engine carburetor, which allows the engine to operate stably even if the air valve is very dirty.
2. Anti-vibration system . To ensure that less vibration is transmitted to the hands of the person working with the tool, the design provides special rubber spacers in some places.
3. One lever . The tool is controlled using just one lever. It performs the functions of turning on the ignition, switching to cold or hot start mode. This makes the job much easier.

Chainsaw Shtil MS 180 technical specifications

The Stihl MS 180 chainsaw has characteristics that correspond to the light class. It is equipped with small volume tanks and is lightweight - 3.9 kilograms. The engine power, rated at two horsepower or 1500W, easily copes with any task.

Description of the saw

The model is a gasoline chain saw with a transverse engine. The tool body is made of light duralumin alloy. In the place where the motor is located, it has lattice cutouts. This ensures the required level of cooling during operation.

Holding is carried out using two handles. One of them is located at the rear and also controls the level of gasoline supply to the carburetor. The second is located a few centimeters from the beginning of the tire. Directly in front of it is a protective metal frame.

The tire is produced in two versions: 35 or 40 cm long. The delivery set also includes a protective cover for it.

The total weight of the tool with empty fuel and oil tanks is 4.2 kg, and with the tire removed - 3.9 kg.

The start handle is located on the left side of the body. Just below it is the fuel tank cap.

The design provides for automatic chain braking after completion of work. This prevents injury from occurring while using the tool.

Upon purchase, the saw comes with a two-year warranty from the manufacturer.

How to start the Shtil 180 chainsaw correctly?

If you don’t know how to start a Shtil 180 chainsaw “cold”, you should strictly follow the manufacturer’s recommendations and requirements, following the algorithm:

• Turn on the ignition (how to set the ignition on a Shtil 180 chainsaw is indicated in the device passport).
• Set the control lever to its lowest point (this will allow the carburetor choke to cut off air from the filter and keep the throttle fully open, allowing the fuel mixture to richen).
• Pull the starter handle, this must be done several times before the first flash passes. This will signal that the mixture has entered directly into the cylinder, and your unit is ready to start.
• Now you can move the lever up one section, while the throttle valve will remain in the same position and the air valve will open.
• All you have to do is pull the starter. At the same time, the Stihl MS 180 chainsaw will operate at higher speeds.

If you need to set the throttle at idle, simply press the throttle trigger and immediately release it. After this, the device will return the speed to normal.

Reliability flaws of the Stihl 180

Sometimes a chainsaw may malfunction or an event may occur to it that could easily be a harbinger of failure. These disadvantages include:

1. Rubbing of the ear mounting of the throttle control lever and carburetor control. Occurs due to frequent use and, more likely, due to attempts to switch the levers to a position where this switching is impossible;
2. Often (after 700-1000 cubic meters of wood) it breaks the through holes of the carburetor diffuser flap. In this case, there is a backlash. It becomes easier to dismantle the air damper completely and plug the holes. Contaminated air penetrates through the cracks, bypassing the air filter. It is very difficult to tighten the valve bolts back. Therefore, it is better not to remove the damper unnecessarily.
3. Sometimes the chainsaw engine begins to dangle spontaneously;
4. When compressing the chainsaw crankcase, the oil seals may become crooked. This defect will be noticeable during disassembly, but for the user of the chainsaw, as a rule, it does not appear in any way.
5. Sometimes the air filter is pulled out by the air flow and lifted up. This phenomenon occurs when the fastenings of the top cover wear out and stop pressing the edges of the filter.

How to dilute gasoline for a Shtil 180 chainsaw?

Most owners of saws of this model are wondering what kind of gasoline to pour into the Shtil 180 chainsaw and what proportions with oil must be observed. The best option is a ratio of 1/50, which means that for five liters of the finished mixture, you will need only 100 milliliters of oil.

How to mix gasoline and oil

You can extend the service life of the Stihl MS 180 chainsaw by using a high-quality, properly prepared fuel mixture. Quite often, AI-2 or AI-95 gasoline is used for this model. Please note that only unleaded gasoline is allowed, which can protect the engine from premature breakdowns.

User manual

Operating instructions are included with each product package. Please read this document before use or any repair work.

Operation according to the company’s recommendations will allow you to avoid unwanted breakdowns of the mechanism, increase the service life of the equipment, and reduce fuel consumption caused by improper handling.

The operating instructions for the chainsaw describe the following steps:

• preparation for launch;
• running in;
• preparing the fuel mixture;
• safe work rules;
• recommended consumables;
• do-it-yourself troubleshooting;
• rules for storing the device in winter.

You can fix simple faults yourself by following the instructions. If in doubt, you can take the electrical equipment to a service center. It is easy to find spare parts for this model in the store.

What kind of gasoline to fill

Gasoline and oil must be poured into the Shtil chainsaw in a ratio of 1:50. The quality of these two components directly affects the longevity of the equipment. The mechanism is demanding on the quality of consumables. Low quality fuel or oil immediately affects operating efficiency and increases the wear rate of parts.

How to start

Starting the power tool occurs in the following sequence:

1. Activate the chain brake by tilting the lever forward.
2. Remove the protective cover.
3. Several clicks on the fuel pump reduce fuel consumption when starting the engine.
4. Activate the gas lever and set the throttle to “cold start”.
5. Pull the cable towards you slowly until there is resistance, then quickly until you hear the engine start.
6. After the engine stops, shift the lever one position up.
7. Pull the cable. The engine will start, move the lever up until it stops and lower it.
8. Move the chain brake handle toward you until it clicks.

This process shows how to start a Stihl chainsaw in a cold way.

How to adjust

Carburetor adjustment is necessary in the following cases:

• the saw stalls at idle;
• does not hold idle speed;
• the tool does not start;
• does not develop the maximum possible speed and power;
• increased consumption of the fuel mixture.

The manufacturer has simplified the settings and left only the most necessary levers. The saw does not have screws to reduce or increase the gas flow. This can be achieved by adjusting the needle valve, opening and closing the gap. It is best to contact a service center for adjustment.

How to break in

Running in the chainsaw is necessary before using the tool for the first time. To do this, you need to perform the following steps sequentially:

• make sure there is oil;
• turn off the inertia brake;
• start the device and leave it idling for 20 minutes;
• press the gas trigger every minute;
• after 20 minutes, you can start by cutting small branches, gradually increasing the density and diameter of the material.

Even an inexperienced user can test a new tool.

Chain lubrication

The chainsaw chain is lubricated automatically using a special pump. Oil is supplied to the chain based on the number of revolutions.

In addition to the oil pump, this mechanism includes a guide bar and a saw chain.

The quality of raw materials affects the wear of parts. Do not use transmission lubricant that hardens at subzero temperatures. As a result, the system becomes clogged and requires deep cleaning.

Branded oil can also make the consistency thick in winter; it is recommended to change it to a more liquid material.

Before starting work, it is better to diagnose the operation of the lubrication system. To do this, just hold the end of the tire over a piece of paper. If an oily streak forms, the device is functioning normally.

An insufficiently lubricated headset experiences strong friction and wears out quickly. Therefore, constant checking of the circuit is a necessary condition for operation.

Disassembly and assembly

You can disassemble a chainsaw with your own hands in several stages:

1. Preparatory. Includes removal of the side cover, chain mechanism and bar. After this, the device is cleaned of dirt, oil and dust. Places where oil accumulates can be cleaned with gasoline.
2. Removing the handle comes down to removing 3 rubber shock absorbers.
3. Removing the starter. After removing the top housing cover, proceed to the 4 starter screws. Then you need to remove the fuel and oil tank caps.
4. Removing the flywheel.
5. Remove the drive sprocket and remove the oil pump.
6. The next items to disassemble are the carburetor, ignition coil and muffler.
7. The motor in the tool is held on by 4 screws. After removing it, you can dismantle the piston ring, bearings and seals.

Assembling the chainsaw occurs in the reverse order.

Replacing the sprocket

To replace the sprocket, you need to unscrew the spark plug and install a piston stopper in its place to secure the crankshaft from turning. Then, from the side of the tire, remove the cover and the retaining ring that holds the sprocket.

How to adjust the carburetor on a Shtil 180 chainsaw?

The device configuration is designed for users with varying levels of experience with this equipment. Cleaning, replacement or repair will not be difficult for you, since disassembling the carburetor on a Shtil 180 chainsaw is quite easy.

You can blow out the unit yourself, change the gaskets and needle valve, for which you will need to disassemble the Shtil 180 carburetor. To do this, you need to unscrew the four screws located on the compensator cover, and also unscrew one on the fuel pump. After you open the body of the unit, you should be extremely careful, since even the entry of small debris and even hairs can make the operation of this unit impossible.

Features of running in the Shtil 180 chainsaw

If you have chosen a model from the presented brand, then immediately after the purchase the question arises - how to break in a new Shtil 180 chainsaw? First of all, this process involves checking and preparing the tool for everyday use.

• You will need to treat the engine, as well as the rotation elements, using a special lubricant.
• After the oil is added to the gasoline, the entire piston group for the Stihl 180 chainsaw is thoroughly processed.
• Please note that you need to allow each element to be lubricated, first during idle and then during power stroke.
• It is important that the oil for the Shtil 180 chainsaw is original; you should not try to save money, as this may lead to rapid wear or accumulation of waste.
• It is worth noting that the octane rating must be at least ninety points.
• Try to take breaks to prevent the equipment from overheating. Acceptable gas flows are typical for both idle and operating modes.

The Stihl MS 180 chainsaw, whose instruction manual is extremely simple and clear, can be fully serviced by the user himself, but at the same time, if you do not have the proper experience or you are simply not confident in your abilities, contact a specialist. Qualified technicians will not only run in the unit, but also change the filter for the Shtil 180 chainsaw, spark plugs and other components.

Results

Despite the listed disadvantages, chainsaws are rightfully considered very reliable. The average resource of the cylinder-piston group before its replacement is about 500 cubic meters of firewood, which corresponds to many years of use of the device even in a rather intense mode.

It should be noted that the saw is a purely household saw, intended only for occasional personal use, so those who earn their living with a chainsaw usually choose a more serious device.

The owner who has chosen the Stihl 180 or Stihl 170 or a slightly modified modification of the Stihl 181 should most importantly monitor the sharpening of the chain, the absence of overheating and the quality of the gasoline mixture. In this case, the likelihood that Shtil will let the owner down and refuse is very low.
