Operating instructions, maintenance features

Before using a gasoline chain saw, it is imperative to inspect its serviceability, adjust the bar and chain. When refueling with new fuel, it is also recommended to update the oil in the tank in order to avoid damage to the tool.

To refuel, the instructions recommend using unleaded gasoline AI-92 and special oil for 2-stroke engines. The fuel to oil ratio is 50/1. In other words, you need to take 5 liters. gasoline and 100 ml. motor oil. The waters are carefully mixed, the unused fuel mixture is stored for less than 1.2-2 weeks.

To run in the new saw Caliber BP-1800 16U, you need to use 8–10 tanks of fuel. At this time, you must not overload the chainsaw and allow the motor to overheat.

A full summary of the Caliber with features, tips and requirements for safe operation is presented here:

For safety reasons, when working with a chainsaw, you need to wear protective clothing. Before cutting huge trees, you need to clear the area at a distance of 1.5-2 times the height of the trunk. Make sure that people and animals are not in the tree felling area.

The Caliber chainsaw is assembled in China to reduce the price of the finished tool. Thus, this eliminates the occurrence of low-quality and cheaper fakes.

Adjusting the carburetor on Caliber saws

The carburetor design on all Caliber chainsaw models is the same; they have a standard arrangement of adjustment screws. The factory settings for screws L and N are 1.5-2 turns.

Before making adjustments, you need to make sure that the chainsaw is tight, more precisely its crankcase, the main chamber of the carburetor and the fuel pump. If the saw does not allow air to pass through anywhere, then it can be adjusted, otherwise, you first need to eliminate the cause of the leak, and then make adjustments.

For adjustment, no special tools are required, with the exception of a tachometer; the slots of the adjusting screws are made for a flat-head screwdriver, and it is also supplied with the saw.

more about the algorithm for adjusting the carburetor of the Caliber saw by reading the general article on adjusting the carburetors of chainsaws, which you can find at the link.

All Caliber saws belong to the price category below average. For example, chainsaw on the company’s official website is currently sold at a price of 3,940 rubles.

Compared to competitors' chainsaws, this is a record low price. Even if this saw is of lower quality than the STIHL MC 180, it is worth the money. At the very least, you will need to pay four times more for the STIHL, although it also breaks down and requires periodic maintenance.

Headset

The saw works with a standard kit, which includes a removable 16-inch bar and a saw chain with a more common 3/8-inch pitch. The design of the clutch and the drive sprocket crown ensures smooth starting and running of the chain in all operating modes.

• Lubrication and cooling of the headset is done by supplying chain oil to the working area, supplied to the inlet of the oil pump from a 260 ml reservoir built into the body.
• Increased safety of sawing operations is facilitated by the effectiveness of the inertial emergency chain locking mechanism, which is triggered when traumatic and unusual situations occur.
• The combination of a massive motor with plenty of torque and a 16-inch tire allows you to work with wood up to 350 mm in diameter.

Structural properties

Despite the budget price range, the Caliber saw of any series is equipped with modern systems for easy starting and air purification.

A number of measures have also been implemented to extend the service life of loaded engine parts, increase operating comfort, and improve the industrial design and ergonomics of the product range as a whole.

On the chainsaw market, the Caliber chain saw is represented by models driven by carburetor power units and electric motors. These options have their advantages and disadvantages, so they are in approximately the same demand.

Owner reviews

Oleg, 34 years old, Pervomaisk:

“This is not an expensive chainsaw, but not a very high quality one . The engine gets very hot, and then you have to wait until it cools down. The starter cord is not secured very well and you have to make a knot. It’s suitable for small jobs, but I don’t recommend it for long-term use.”

Alexey, 45 years old, Kirov:

“I purchased a saw for home use: cutting down a tree, chopping firewood, etc. Now it has been working for two years and I am satisfied with its operation. It starts right up, the cut is smooth, and for the price it’s just perfect.

READ Chainsaw Homelite Carburetor Adjustment

The engine of the tool runs on a fuel mixture of unleaded gasoline mixed with an octane rating (92 and higher) and specialized oil designed for two-stroke engines.

Controls

Even the cheapest Caliber are equipped with a primer - a device for pumping fuel into the carburetor during a cold start. In higher-quality chainsaws of inexpensive series, it may be absent, but with the Chinese it comes in handy = instead of 4 - 5 jerks, you have to make 2 - 3 until the saw “grabs”.

There is a choke control button on the right - in the extended position, the air channel is blocked, and the mixture is enriched, which makes starting easier. The ignition switch is an ordinary two-position button, which receives a lot of complaints - it is hard to feel with gloves on, and often breaks. The gas trigger is standard, with an accidental start blocking flag.

Saw set

The saw is equipped with a 40 cm long bar. This is an average parameter that allows you to successfully cope with large and medium-sized logs. It is recommended to cut trunks thicker than 40 cm in several passes, giving the saw a break. , stretches greatly and quickly dulls. Actually, its purpose is to run in the saw, as well as to train beginners so that they do not unknowingly “plant” a good blade. adjusted from the end of the saw - not the most convenient, but a reliable location.

Engine

The chainsaw is equipped with a single-cylinder two-stroke classic with a working volume of 45 “cubes”. The crankcase is made entirely of metal to increase service life. Because of this, Caliber saws turn out to be quite weighty; this specimen is difficult to hold suspended for a long time; the large mass helps with vertical cross-cutting, when the saw bites into the tree under its weight.

Appearance

The saw has a completely orange body of a bright color, which it inherited from professional sawing machines. Only the handles and brake frame are black. The plastic of the case is of average quality; upon careful inspection, you can find burrs and flash after casting. The moving parts are quite strong, their strength is quite enough for domestic use. Almost every saw assembly is accompanied by explanatory stickers, which will make it easier for beginners to master the unit.

Carburetor

An inexpensive chainsaw is equipped with a Chinese-made carburetor, which is an attempt to copy the famous Walbro. Even the name repeats higher quality products, but in such a way as not to violate copyrights - exclusively in the style of the enterprising Chinese industry - Wanbao. Like its famous prototype, this unit has three adjusting screws. Under one of them - T - there is a through hole in the housing, the other two - H and L - are closed with a rubber seal to prevent contamination.

Self-repair problems

The problem in many cases is complicated by the lack of comprehensive information on repair technology. According to foreign manufacturers, after the saw has exhausted its service life, it should be scrapped, so the maintainability of many budget-level models raises reasonable doubts.

Professional-grade chainsaws are more difficult to restore.

• The problem is compounded by the high cost of spare parts.
• It is possible that to restore the functionality of individual components and mechanisms, in particular, to configure fuel equipment, special equipment will be required.

Replacing expensive branded parts with affordable but short-lived Chinese analogues does not justify itself economically. Practice shows that these components produce a service life of 50-60% at best.

Disassembling the starter to replace the cord does not create problems for an experienced user, but in most cases the plastic case cannot be repaired. The Chinese chainsaw range is mostly copies of the most popular European models, so we disassemble the Chinese chainsaw according to the standard scheme.

Worn parts of the saw set cannot be restored.

Purpose

The area of ​​application of the chainsaw is private households. It is well suited for caring for gardens, fruit trees and other green spaces. The weight of the saw, albeit with some difficulty, allows you to work with it to trim branches and branches, and thin out the crown. If there is a need to remove dead wood or clear up an overgrown area for improvement, then Caliber will not hesitate to do so. In construction, it can successfully cope with work on the ground - lifting it with outstretched arms to trim already assembled wooden structures is still difficult.

Nobody perceives Caliber 1800 -16U as a semi-professional or farm saw Domestic buyers of chainsaws generally have inflated demands on cheap Chinese equipment. The built-in safety margin is designed exclusively for domestic use.

Competitors

Interskol PCB-16/45L

BISON PBC-M450 40p

CHAMPION 241-16

Many saws of a similar price category and power parameters can compete with Caliber for purchase for use on a summer cottage. Here are the more expensive Interskol PCB-16/45L, Russian-assembled, and the “brother-Chinese” ZUBR PBC-M450 40p, and the more famous CHAMPION 241-16. The companies Carver and Patriot offer devices that are much weaker for a similar price; samples comparable in power are less common and cost a fair amount. The more expensive and high-quality Partner is not a competitor in price, not to mention such “mastodons” as Makita, Echo or Stihl.

Design

Both the external and internal design of the saw is typical for the entire Caliber . Thanks to this, all of them have a high degree of unification, which also reduces the cost of production. The design of different saws of the same model range consists of a slight difference in the volume of the cylinder, and, accordingly, the overall size.

Compression recovery

Less complex repair of the piston group. To dismantle the cylinder, it is enough to remove the threaded fasteners and lay the saw on its side to prevent pieces of a damaged compression ring, piston skirt or other foreign objects from getting into the engine crankcase.

The cylinder bore wears unevenly, so installing a new piston does not have a significant effect. As a rule, during a major overhaul, after checking the suitability of the crankshaft, a complete set consisting of a cylinder, piston, compression ring and piston pin is installed.
