Gasoline does not flow into the Partner chainsaw
How to flush a chainsaw carburetor?
It is best to use a product that is commercially available in pressurized cylinders to remove stubborn dirt from the assembly. The kit includes a dispenser and a long thin tube that allows you to spray the product in any hard-to-reach places.
It must be remembered that cleaning the carburetor on a chainsaw is carried out using flammable chemicals. You need to work with them in a special protective mask and only in well-ventilated areas.
How To Easily Fix A Chainsaw That Bogs Down By Adjusting The Carburetor
To clean the carburetor on a chainsaw, the unit will need to be partially disassembled. The throttle valve, adjusting screws, body and other carburetor parts will need to be rinsed with a bottle cleaner and set aside until completely dry. Once all the elements are dry, the unit can be assembled and installed back on the chainsaw.
Gasoline does not flow into the chainsaw
There can be many breakdowns associated with a chainsaw, and it can be quite difficult to solve some. If you have been working with this gasoline tool for a long time, you have had a problem when gasoline does not enter the carburetor or does, but it is very difficult and does not allow the chainsaw to start normally. Fortunately, experts have long found the reasons for such a breakdown and therefore we have compiled the main methods of repair.
Chainsaw not oiling, check this first. Easy fix.
First of all, we check for commonplace reasons, for example, the presence of gasoline in the tank. If there is one, we check the process of supplying fuel from the tank through the wire. To do this, it is enough to disconnect the gas line from the carburetor and try to pump fuel. It will be correct to supply fuel through the hose in jerks, this will make sure that there are no problems with the gas tank. If fuel does not flow even in jerks or drips too slowly, the reasons may be as follows:
Surprisingly, even having a full tank can cause no fuel to flow. Therefore, try not to fill the tank to the maximum. An overfilled fuel tank can pressurize the tube that connects to the carburetor.
Saw no fuel supply. Petrol powered tools
And how much Nm is actually needed? Necessary theoretical digression.
From resistance material M (torque) = τ (stress in the rod) W (polar moment of the section, equal to ΠD3 / 16)
The bolt strength class means the following: 1 digit. 1/100 of the nominal value of the tensile strength, in MPa 2 digit. the ratio of the yield strength to the tensile strength That is, a bolt of strength class 6.8 has a tensile strength of 600 MPa, and a yield strength of 6000.8 = 480 MPa The obtained figures are confirmed by the experiment carried out at the training center: an M6 bolt with a strength of 8.8 begins to “float” (irreversible plastic deformations occur) at 17 Nm, and when a torque of 23 Nm is reached, destruction occurs. Let’s make a similar calculation for screws and self-tapping screws: For the calculation, the full diameter is taken, the minimum section is much smaller! Conclusion: To use the most popular fasteners with Ph3 and Pz2 splines, a tool with a torque of no more than 6 Nm for a diameter of 4.2-4.5 mm is required, in rare cases up to 10 Nm for fasteners with a diameter of 5.0 mm. Exceeding the specified moments will damage the fasteners and the screwdriver bit (bits). 13 self-tapping screws Ø4.5 x70 mm are twisted into a “pie” 121 mm thick. The torque of 3.0 Nm, developed by a Makita DF010DSE screwdriver, is enough for confident screwing of a self-tapping screw Ø4.5 x70 mm to its entire length. If, to prevent the destruction of screws and self-tapping screws, a torque of 2-3 Nm is needed, rarely 5-6 Nm, and in exceptional cases up to 10 Nm, then why is a torque of 20.30.50 Nm on an electric screwdriver? What else can a drill driver do? If a drill means drill! What torque is needed for drilling? Theoretical digression Consider drilling steel as the heaviest drilling in metal. The torque is calculated by the formula Mcr = 10CMDqSyKp, where D is the drill diameter, S is the feed, the rest of the signs are correction factors. For steel with δ = 750 MPa: CM = 0.0345, q = 2.0, y = 0.8, Kp = 1.0 The drilling speed is taken to be 20-25 m / min (with spray cooling), the corresponding speed is set to 4 th column. Torque, rotational speed and shaft power are related quantities. The value of the required shaft power is entered in the 5th column. Let’s look at the numbers: To drill a Ø10-13 mm hole, a torque of 8-15 Nm is required. At a recommended drilling speed of 720.550 rpm, this requires a power of 570 to 850 W. And what is the power of a cordless drill ?
There are 3 holes in a conventional drill chuck for good reason: For a secure fit, the chuck must be tightened alternately through all 3 key positions. In a chuck, tightened through one hole, a Ø10 mm drill is turned at a torque of 13.5 Nm, and through 3 holes (as expected) at 23 Nm. And to drill Ø13 mm when drilling steel, you need to transfer torque
15 Nm. Those. when the chuck is tightened through one hole, the drill will rotate! Cordless drill power (consumed) = Battery voltage Current consumption The current consumption for powerful models is 20-25 Amperes Thus, the power for the cordless tool will be: For 12 Volts: 240-300W 14.4 Volts: 290-360W 18 Volts: 360– 430W The torque for the most powerful (18volt) drill will be: at a speed of 1500-1700rpm: 2-3Nm at a speed of 300-400rpm: 8-14Nm drilling steel with a drill up to Ø7mm drilling steel with a Ø10-13mm drill These are the torque values at maximum power. (in drilling mode) When the motor is overloaded when tightening rigid fasteners (for example, bolts), the torque value reaches 30-40 Nm. It is these values that are indicated in the characteristics as the maximum soft / hard torque. They have no practical value! If, when working with a tool, a torque of large values is required, then a specialized tool is needed specifically for this work. Summary: For the average user, it is enough to have a torque of 3-6Nm adjustable with a ratchet in a cordless drill / electric screwdriver to work with standard fasteners with a head size up to Ph / Pz2, and up to 10Nm for Ph / Pz3. For drilling steel, plastic, wood with drills up to 10 mm in diameter, a torque of 10-12 Nm is sufficient. Torque more than 15Nm requires the use of a specialized tool and should not be included in the scope of the universal drill-electric screwdriver.
Chainsaw carburetor adjustment. what a beginner needs to know?
Initially, all adjusting bolts are in the factory positions. this ensures that the optimal amount of fuel and air is sucked in. However, due to prolonged use of the saw in difficult conditions, the factory settings of its carburetor may be violated. Even a slight movement of one of the bolts by 1/5 of a turn will seriously damage the saw motor. In this regard, the operator must constantly monitor that the adjusting bolts are in the optimal positions set at the factory.
If for some reason the work of the node has been disrupted, then it will need to be reconfigured. For this, 3 adjusting bolts are provided in the assembly. The first of them is marked with the letter H. it is needed to tune the engine of the chainsaw when operating at maximum speed. The second screw marked L is used to adjust the motor when running at low rpm. The third screw can be labeled T, S or LA. Its task is to configure the internal combustion engine when operating in idle mode.
Chainsaw carburetor tuning must be carried out with a completely serviceable engine. Immediately before adjustment, you will need to inspect the air filter, and, if necessary, clean or replace it.
Air filter
If the chainsaw does not supply gas to the carburetor, pay attention to the type of air filter. Due to its inadequate operation, the unstable operation of the chainsaw begins, which in the future is difficult to start or stalls during operation. Air is harder to enter the device and makes the mixture too rich. You can hardly start it, and the reason for this is the formation of dust.

Poor quality gasoline
Who is the most experienced user of a chainsaw knows that the fuel in the tool reservoir cannot be left forever. What exists is that during prolonged storage, unnecessary processes will occur inside the tank with the formation of resin and polymerization of various components. Do not leave fuel in the tank for more than half a month, and if your tool is started with such fuel, this will lead to the formation of carbon deposits on the parts of the CPG (rings, piston).
