• the oil tank is empty.

Technical differences of the Imperial modification

The version of the Patriot 3816 Imperial chainsaw differs from the base model in its increased weight to 5.4 kg, the presence of metal covers for the manual starter and clutch mechanism, a double-action brake, a semi-automatic carburetor and a chrome coating on the cylinder mirror.

The characteristics of both chainsaws positioned by the manufacturer were fully confirmed during practical use. In winter, the engine starts with half a turn; in summer, its traction properties remain stable even at temperatures of 30 degrees Celsius or more.

Design Features

Patriot chainsaws do not have such rich equipment as, for example, Shtil or Husqvarna saws. After all, this is just a “good Chinese” put on an assembly line. However, saws have a number of serious advantages in comparison with their competitors from China:

• On the piston of all saws, without exception, two oil scraper and compression rings are installed;
• chrome-plated working surface of the cylinder;
• The connecting rod and piston group (SHPG) are made of forged steel.

These 3 points give Patriot chainsaws a reliable engine, which significantly increases the service life of the tool.

It is worth noting the unification of Patriot chainsaws. Many users note the excellent interchangeability of spare parts. From tires and chains, to carburetors and engine components.

Contents of the instruction manual

The attached instructions contain information about the features of operation and routine maintenance of the chainsaw, recommendations on the range of consumables and the elimination of possible failures and malfunctions.

In particular, if the engine does not start, does not develop full power, or randomly turns off, you should make sure that the spark plug is working properly and that there is no water in the carburetor. The cause of poor performance of the power unit may be a clogged air cleaner or poor quality of the fuel poured.

In any case, independent repairs involving disassembling the engine or other systems and components of the chainsaw should only be carried out if you have certain qualifications.

Summing up

Patriot chainsaws have gained great popularity among the population of the country, this can be seen from numerous positive reviews. The price-quality ratio offered by Patriot takes its toll. Saws are great for household use. In the event of a breakdown, they can easily be repaired with their own hands, because... there are no problems with spare parts, and repairs do not require special tools, as is the case, for example, with Husqvarna saws.

The choice of Patriot chainsaws is huge; the main differences are engine power, total weight of the saw and tire size. The nature of the tool's use depends on these parameters. Choose an option for yourself with an emphasis on the criteria you need and then you will only get positive emotions from use.

Specifications

The dry weight of the chainsaw without fuel and oil is 4.9 kg. The overall dimensions of the product, 450 x 285 x 306 mm, determine its suitability for use in hard-to-reach places, in particular, during the construction of complex log and beam structures.

Competitors

STIHL MS 180-16

Oleo-Mac GS 35 C-16

Husqvarna 140

If you select a replacement based on engine power and tire parameters, then alternative saws are divided into two groups. Some are significantly more expensive - these are STIHL MS 180-16, Oleo-Mac GS 35 C-16, Husqvarna 140. They can be according to the following scenario: a person took a Patriot to see if a saw of this size would be useful to him. And after the answer is positive, a solid branded product is purchased. But the real competition for the Patriot comes from its price classmates, for example, CHAMPION 237-16, Eco CSP-164, Carver RSG-38-16K. They are designed for people who use the tool occasionally and are not ready to shell out more than 10 thousand rubles for them.

Engine

The drive used is a 38 cm3 two-stroke gasoline engine, which develops power of up to 2 hp in operating mode. The durability of the engine is achieved through the manufacture of critical parts from forged steel, chrome plating of the internal diameter of the cylinder, and the use of high-quality oils.

Fuel with a dosed admixture of oil is supplied from a tank with a volume of 0.31 liters. One refill is enough for two and a half, and sometimes all three hours of continuous operation. The manual starter successfully realizes the advantages of the simplified starting system of the power unit.

Cylinder-piston group

It happens that the engine does not start or functions poorly due to low pressure in the cylinder. The malfunction may consist of a piston, cylinder or bearings that have become unusable, or piston rings that have sunk. You can look at the problem in general terms; to do this, you need to remove the muffler and inspect the system.

You can measure the compression in the engine by placing a compression gauge in the spark plug hole. After time, you can draw conclusions based on the results of the measurements. The problem can only be resolved by completely disassembling the system. If scratches or chips are visible on the piston, it needs to be replaced. The piston ring must be installed in its correct place, clean and intact.

Carburetor adjustment and tuning

Factory adjustment of this device ensures a combination of maximum traction parameters with economical consumption of fuels and lubricants. It is not recommended to interfere with the operation of this device unless absolutely necessary.

Routine work on cleaning the carburetor and adjusting the quality of the mixture taking into account the ambient temperature is covered in detail in the attached operating manual. The reason for the lack of traction, engine interruptions or engine shutdown may be the presence of water condensate in the float chamber.

Chainsaw muffler malfunction

It often happens that during prolonged operation, the walls of the exhaust pipe become covered with soot, which prevents the free exit of exhaust gases. In this case, you should remove the muffler (if possible) and wash it with detergent, then dry it thoroughly with a hairdryer

ATTENTION! Carbon deposits contain carcinogens. During dry brushing, it can enter your lungs, which poses a threat to your health.

The cause of carbon deposits is usually an incorrect gasoline-oil ratio or the use of low-quality and incompatible oil. Carefully read the operating instructions for your chainsaw to prevent this from happening in the future.

Working equipment

This assembly includes a 16-inch guide bar with a 1.3 mm working slot width and a 57-link cutting chain driven by the saw drive sprocket. The chain pitch is standard 3/8 inch; for automatic lubrication, oil is drawn from a 0.21 liter reservoir during operation.

The working equipment also includes a tensioning device, a catcher that prevents injury when the chain breaks or comes out of the bar groove, and a dual-circuit brake that ensures instantaneous stopping of the cutting apparatus during an emergency stop.

A stretched chain forces wear on the drive sprocket and contributes to the formation of emergency situations, so after the end of its service life it must be replaced with an identical model costing about 700 rubles. Practice shows that cheaper chains exhaust their designated resource by a maximum of 50-60%.

Frequent faults of the Patriot PT 3816 chainsaw and do-it-yourself repairs

As mentioned earlier, the shock absorbers on the Patriot 3816 often break off. Replacing them is easy. It is enough to unscrew the two screws holding the shock absorber, remove the defective part and install a new one in its place.

Another common problem with the Patriot 3816 is a broken clutch spring. It is not difficult to diagnose this malfunction, because the chainsaw chain will spin constantly, and the saw will stall if you put the bar on a chock at idle trying to stop the rotation of the chain.

To replace the clutch, you need to remove the top cover of the engine and unscrew the spark plug, then, through the spark plug hole, use a cord to stop the piston stroke. Next, you need to remove the side cover, chain and bar from the chainsaw, thereby providing access to the clutch. After this, use a special key (you can use a key from an angle grinder) to unscrew the clutch.

We assemble the saw in the reverse order.

Advantages

The Patriot PT 3816 chainsaw is manufactured in China under an American license, therefore, in all respects it meets the requirements of currently valid European and world standards.

• The model is sold in an affordable price range, is easy to operate, safe and durable for everyday use.
• The designers have developed full-fledged noise and vibration protection systems. The background noise was reduced to 113 dB, and the vibration level was reduced to a minimum, helping to reduce the carver's fatigue by almost half.
• When calculating the configuration of the case, holders and placement of control elements, classic and proprietary ergonomic solutions are used.
• In addition to the standard set, the list of factory equipment is replenished with protective equipment and a container for proper preparation of the fuel mixture.

A little about the world famous manufacturer - Patriot

Just imagine, this manufacturer began its activities by creating a small service center, which was located in Massachusetts. And in just thirty years, this small enterprise has risen to world heights.

Naturally, the company had to face rebranding, functional changes, and design aspects were also adjusted over the years, but, nevertheless, this manufacturer still managed to provide the world with its own and unique products.

Today, construction and garden power tools are produced through factories located in different parts of the world, including countries such as
Russia, China, Italy, the USA and Korea .
The products of this manufacturer are extremely popular, and this is not surprising, since its distinctive features are the unconditional high level of product quality, as well as a stable and optimal pricing policy for the products. In addition, one cannot help but note the fact that all equipment produced by the company has a safety certificate and meets all international assessment standards.

Analogs

The production of budget chainsaws is a significant income source for many well-known manufacturers of household and professional equipment. The domestic market offers a wide selection of identically priced models from well-known European and Asian brands.

These are budget chainsaws - Oleo Mak model 35 costing 5,600 rubles and Alpina 361. More expensive options are Partner 350 Chorme and Shtil 180. The budget segment of chainsaw products from the Husqvarna and Champion brands has proven itself well.

Fuel supply

In addition to the above-mentioned clogged breather, other problems may arise during the fuel supply. The main obstacles may be:

Clogged fuel filter. To check the device for this malfunction, you need to disconnect the fuel hose and see how the fuel flows. If the flow is weak, the filter may need to be cleaned. The filter device is removed through the filler hole of the tank and cleaned; if the contamination is too strong, it is replaced.

Lack of fuel. In this case, the problem may lie in several factors. The first is a dirty air filter. The problem is that enough air is not delivered to the carburetor, causing the engine to run poorly. The filter must be removed, cleaned, washed and dried, and then put back.

The second reason is an unadjusted carburetor. It, that is, adjustment is carried out with three screws.

And the last reason is a problem with the integrity of the membrane or contamination of the carburetor channels. As in other cases, it is necessary that the components are dry and clean.

Owner reviews

After many years of using a domestically produced chainsaw, I decided to buy an inexpensive, but new, imported device. The new Patriot 3816 started on the second pull, I liked the sound, the exhaust was clear, but not strong. The first tank of fuel was burned almost at idle, after which the main work began on clearing the territory of the old garden for construction. The machine did not disappoint; it cut 68 fallen trees into meter-long pieces without a single failure. I didn't like the inconvenient chain tensioning system. It seems that there is an increased oil consumption, the tank is enough for one fuel fill. Artem Dmitrievich

I am a supporter of reasonable sufficiency, so I approve of the purchase of professional equipment for household needs only if you have extra money. I have been periodically using the Patriot chainsaw, purchased for 6,900 rubles, without any failures or malfunctions for two years now. The original tire is still working, the chain has stretched significantly, but a lot of work has been redone. After six months of operation, problems began to arise with starting, until I decided to replace the spark plug. Everything was restored to its previous level. In general, there are no grounds for complaints. I recommend. Garik

General principles of disassembly

Basically, all chainsaws have the same components, which are dismantled according to a certain scheme. If the saw assembly is Chinese, then there is nothing to worry about: most often they are made in the likeness of European models. How to disassemble a chainsaw:

• The clutch cover is removed.
• The starter cover is removed. To do this, you need to unscrew the screws and remove the cross handle.
• To remove the handle, you need to remove the cover that covers the air filter.
• The gasoline hose is removed from the fitting cover.
• The saw body is dismantled. You need to unscrew the screws and remove the oil tank cover.
• Before removing the ignition module, you need to disassemble the clutch drum: you need to rotate the crankshaft clockwise until the piston closes the gas outlet.
• Then you need to unscrew the clutch on the chainsaw and remove the clutch: you need to hit it lightly with a hammer.
• The screws are removed, the gas tank with the oil hose is dismantled.
