It is important that the number of links does not fall within the range of 46-52 pieces.

Service

The fuel mixture used consists of AI-95 or AI-92 gasoline and oil for two-stroke engines. Before starting work, it is necessary to run-in the engine at medium speeds and light loads. The ratio of gasoline and oil for Partner 350 chainsaws during break-in is 35 grams per 1 liter. After it, you need to dilute 20 grams of oil with one liter of gasoline. The break-in period for Partner 350 chainsaws should be 1.5-2 tanks.

Oleo-Mac Polar Lube Chain Oil

AL-KO 2-stroke engine oil

An important feature that determines the proper operation of Partner chainsaws is chain tension. You can do it yourself

Poor tension can cause the tire to fly off or be damaged. With excessive tension, the load on the motor increases, which subsequently wears out the saw faster.

The main aspect that determines the safety of working with a Partner chainsaw is the availability of protective clothing. Hands should be worn with gloves made of strong fabric. In general, pants with a special lining that will stop the movement of the saw during emergencies and the same jacket are perfect for the body. Shoes should be just as durable.

It is strongly recommended that owners adhere to the following tips, which will make work much safer and more convenient:

  • The saw should be kept as close to the body as possible - in this case, the hands will receive less load. This will also help you better maintain balance and control the process.
  • When changing position, it is necessary to turn off the engine using the chain stop activator. Before performing a maneuver, you need to make sure that it does not rotate.

Also, it is necessary to comply with a number of felling safety requirements:

  • It is necessary to determine the direction in which the tree will fall. It is necessary to take into account the direction of the wind, the slope of the soil, and the growth of the tree itself.
  • The space around the tree must be cleared of bushes, undergrowth, and foreign objects. Clearing should be done at a 45 degree angle from the back and sides of the tree.
  • A safe distance is considered to be two tree lengths. There should be no strangers in this gap.

Setting up the Partner 350 chainsaw

According to the operating instructions, before starting the Partner 350 chainsaw, it undergoes special training, which includes:

  • installation of the saw set or checking its tension for already installed parts;
  • checking the serviceability of the brake band;
  • placing the brake handle in a ready state as shown in the figure;

  • filling the oiler and gas tank with fuels and lubricants. The fuel mixture is prepared in a ratio of 1:50 from oil for 2-stroke engines and unleaded gasoline AI-92.

The launch is carried out on a flat surface, sharply pulling the throttle cable. During a cold start, open the air damper and allow the chainsaw to warm up. Only after this can you gain momentum and move on to woodworking.

All possible nuances of adjusting the Partner 350 chainsaw with your own hands are described in detail in the operating instructions. If they are not followed, the instrument is not insured against malfunctions and repairs, the budget of which may be unpredictable.

Chainsaw operating instructions

1. The main parts of a chainsaw: a holder (consists of a gripper, a pusher and a step) a rattle (consists of a navel, a lever, a button, a puller, two screws, a gas tank and an oil tank) a saw (such a long flat drill sticks out in front, consists of a blade and put on the chainsaw is not golden!!!) a system for ensuring the safety of the chainsaw operator in the event of a sharp rebound of the blade with the working chain upwards and preventing injury to the chainsaw operator by the blade with a moving chain in the head, back, or other chainsaw operator (there is such a tricky plastic grip above/in front of the sawmill ) 2. Before lighting a) Pour two magical solutions into the saw. The first solution is difficult to prepare and consists of a flammable toxic liquid Gasoline AI-95 (do not smoke! keep a hook, a bucket of sand, a powder fire extinguisher and a 66-meter ladder at the ready) and the magic composition Oil for two-stroke engines (included in a suitcase - white and yellow a bottle of green thick rubbish) mixed in a ratio of 40 to 1. Attention! Violation of the ratio does not guarantee the occurrence of a magical effect. Measure with a pipette, beaker, test tube to the nearest drop. It is allowed to measure with corks, caps, glasses, glasses. It is allowed to change the ratio from 30 to 1 to 50 to 1 + - 5 to 1 It is not allowed to mix by eye, it is better to mix approximately and offhand. Mix in a separate container, canister, bottle, pot, palms. The resulting solution has an attractive color and smell. The solution is necessary for rattling. A distinctive feature of a properly prepared solution is that the rattler will work like a magic word. If the rattler does not work, you should replace the magic word with a more magical one. Outdoor! If the composition is taken internally, bite charcoal and smoke. About 300 milliliters of the first solution is poured under the large neck of the chainsaw (near the holder). The second solution is poured into a small neck (near the saw blade). This includes any oil, motor oil, transmission oil, nigrol, mineral water, synthetic and semi-, castor oil and, according to rumors, even waste oil. Attention! Cold starting on thick oil should not be difficult. The tank capacity is about 100 milliliters. The solution is necessary for the saw to work. b) Check the correct condition of the saw blade. The chain in the middle of the web, if you pull it, should move 4-5 mm. If more or less, the chain needs to be tightened. This is done like this: there is a magic key (not gold) in the suitcase; with one end of the key, two nuts are loosened by 1-2 turns close to the blade; on the side opposite the plugs, the second side of the key turns a small screw next to the blade, perpendicular to the plane of the nuts in a clockwise direction - for tension, counterclockwise - to loosen, check the chain tension, then again tighten the two large nuts with the first side of the key 3. In order to buzz a) pour both magic compositions into containers specially designated for them. do not let the ingredients mix!!! b) close the special containers with special plugs c) cock the safety system... (press it firmly and sharply towards the saw, it will either press lightly or click - it has worked, then pull it towards you with great force until a dull knock occurs — the trigger is cocked) d) track the position of the button on the rattle (the button should be in the OFF state) e) press the rubber navel next to the large plug several (5-6) times until magic liquid number 1 appears in it (in the navel) f) pull the lever several (3-4) times at full speed, in order to ensure the flow of both liquids into all the necessary tubes and slits g) disperse those around you at a distance of at least 5 meters, you can not drive away the especially annoying ones, but let them hold on saw h) turn on the button!!! (move to the ON position) i) place the chainsaw on the ground j) make sure that the saw does not touch the ground - this is not a shovel, but a chainsaw l) step on the step with your right foot m) sharply pull 2-3 times with your right hand on the tug n) rattle won’t turn on o) say the magic word p) kick the rattle p) try to pull the blue lever (choke) next to the push button c) suddenly it will help t) although it never helps y) but it should f) even, it seems, helped a couple of times x) just in case case, say the magic word c) repeat operations e-k-l-m-n h) in case of failure, repeat operations e-p-r-s-t w) if, more than expected, the rattler has started working - say the magic word w) an unheated rattler may not hold idle speed even with suction, so turn on the saw by pressing the trigger with the fingers of your right hand, first pressing the safety catch on top with the palm of your right hand. The choke lever will automatically retract. ATTENTION!!! A working saw is a terrible weapon!!! Do not give it to children, pregnant women, old people, the faint of heart and harsh Siberian lumberjacks!!! ъ) if all the above operations did not help, say the magic word y) there is a trick that almost always works. Step on the step with your right foot, and at the same time press the pusher from below with the same foot (with your right foot), for which you first press the safety catch. b) then pull the lever again e) while continuously saying the magic words j) the rattle will rattle i) say the last magic word - you can fight 4. How to fight. when you press the pusher, the saw starts to work; if when you press the pusher, the saw does not work, then the safety system has worked... in this case, turn off the rattler and cock the safety system again... do not keep the saw idling for a long time (without biting) - this is harmful to it select a victim and carefully approach him. try not to scare off. It is forbidden to poke the victim with the end of the saw - the consequences can be sad - the canvas will fly up. if your hands are strong - in the face, if weak - in the back. you won’t even have time to say the magic word... the saw is inserted into the flesh of the victim with the bottom side of the blade, preferably closer to the middle of the blade, from above, below, from the side, in case of cutting from bottom to top, you can work with the top side of the blade, but be extremely careful, do not press with all your might fool up - the consequences are described above, if during the attack the victim resists and pinches the blade, try to prudently remove it from the trap and attack slightly from the side to widen the edges of the laceration; if this fails and the blade gets caught in the trap, the saw is blocked and it does not work - turn off the saw blade and use available tools (crowbars, axes, other operators) to try to expand the trap to remove the saw blade. do not pull the chainsaw out of the trap as hard as you can - it hurts the victim when working with the chainsaw, stand to the left of it, so that the plane of the blade passes by you, a little to the right. just in case. fully filled tanks are enough for 30-40 minutes of continuous operation of the rattler or for 2-3 large victims. It is not recommended to use the saw on others - they may be offended. It is recommended to work in closed shoes, because from under the saw a strong stream of sawdust hits the shoe. then you will be tortured to get splinters out of your socks 5. In order not to buzz a) press the button to the OFF position b) say the magic word 6. Return everything as it was, try not to leave magic liquids in the tanks - they will leak out, you bastards! put the chainsaw in the suitcase, do not lose the magic key, put it in the suitcase too, put away the white and yellow bottle with the magic liquid, say the magic word Note: the list of magic words is passed down orally from generation to generation. When written, they lose their magical power.

Chainsaw “Partner” 350 malfunctions and their elimination

The most vulnerable systems of the 350th chainsaw from the Partner brand are:

  • motor part;
  • ignition system;
  • lubrication supply problems.

Diagnosis of engine failures

If the engine stalls or does not start at all, the reasons may be the following:

  • lack of gasoline or air supply;
  • there is no spark to ignite.

For a more accurate analysis of the situation, you need to:

  • make sure that the fuel reaches the carburetor part - if not, then: the saw’s gas tank is empty:
  • the float needle is clogged;
  • air access to the fuel tank is stopped;
  • The gasoline filter is clogged. These breakdowns can be eliminated by cleaning the cleaning systems and refilling the chainsaw with high-quality fuel.
  • if gasoline reaches the carburetor, examine the spark plug for defects - it should be dry and with the correct gap. Based on its external condition, one can judge possible malfunctions of the entire instrument (see figure below).
    • If it does not spark after connecting to a grounded wire, the problem is with the spark plug itself and will likely need to be replaced. In addition to the spark plug, other spare parts often fail - the ignition coil or switch;
    • detecting a wet spark plug is a sure sign that the spark plug is flooding. This may be due to:
    • incorrect or failed carburetor factory settings;
    • filling the carburetor block with fuel.,

    In any case, it is necessary to update the carburetor settings.

    Carburetor adjustment

    If the “Partner” chainsaw does not start well, smokes heavily and does not produce the power specified by the manufacturer, the question of how to adjust the carburetor of the “Partner” 350 chainsaw should become central to every user. To solve it:

    • warm up the engine;
    • tighten screw L until it stops, then loosen it by a quarter;
    • if the saw continues to stall at idle, turn the T jet;
    • For correct operation of the “Partner” chainsaw under load, use screw H to achieve maximum speed.

    For installation, it is advisable to have a universal key and a tachometer (crankshaft rotation counter) on hand. Carburetor installation and ignition adjustment are still performed. Therefore, there is no need to reconfigure a completely new saw.

    Oil supply system malfunctions

    The situation when chain lubrication involuntarily flows out of the chainsaw body and does not reach the cutting parts does not indicate the need to repair the oil pump, clean the oil supply pipes, or replace them with serviceable spare parts. In addition, lubricant drips may indicate depressurization of the connection between the pipes and the oil sump. If these breakdowns are not corrected in time, the chain will begin to overheat, stretch and fail prematurely.

    Do-it-yourself repairs to the Partner 350 chainsaw should only be carried out by people who understand its structure and operating principle. Only in this case can we hope that the replacement of the drive sprocket or crankshaft will be carried out correctly and safely for further work.

    Principles for choosing a chainsaw


    So, the question arose of which saw to choose for work on a summer cottage. Of course, it should be a chainsaw, since it is mobile and does not depend on the energy source. Such a device can be used on a tourist trip to collect wood debris in the forest.

    Quality products, not just saws, are identified by well-known brands. But here there is a danger of falling into a replica created in artisanal conditions. Therefore, it is worth taking a closer look at the product. More often, expensive instruments from world leaders Stihl, Husqvarna, Echo, Solo are counterfeited as expensive brands. Therefore, you can purchase a Partner 350 chainsaw from the manufacturer with less risk.

    The weight-power ratio has a direct relationship. Therefore, a professional tool for country use is not always suitable. You should choose a home assistant with a small reserve of power. The 45 cm tire size on an amateur saw is a marketing ploy; it reduces engine life, and the saw device will jam while pulling.

    A chainsaw is a highly dangerous tool. When working, it is necessary to ensure that children and animals are not accessible to the work area. It is better to cut small boards on specially equipped racks. For your own safety, work in buttoned clothing, glasses and protective gloves. Your feet should be wearing comfortable, stable shoes.

    Options for vibration damping, easy starting, convenient chain tension, and the availability of an air filter create additional convenience when operating the tool. Of the household budget saws, the Partner 350 S chainsaw is in fifth place in the ranking of the most popular ones. And in terms of price-quality ratio, this is the best mechanism.

    Reviews

    Positive reviews from owners of the Partner 350 chainsaw once again emphasize the high quality and reliability of the product. It is noted for its ease of use, cost-effectiveness, and ease of maintenance. In his review, user Oleg writes:

    Everyone was especially captivated by the improved Partner 350s chainsaw. It has absorbed all the best from the base model and has become a little more powerful, which has a positive effect on its use. It has proven itself well when used in subsidiary plots and farms.

    The technical characteristics of the Partner 350 chainsaw and its budget price, along with the simplicity of its design, have ensured its widespread use in private households. Convenient and economical, safe to use, it has all the qualities of world brands in its line. In addition to its main function, when using additional attachments, the saw can cut metal, be a water pump, a drill, and even a boat motor.
