Vital structural elements in Oleo-Mac chainsaws
Italian chainsaws from Oleo-Mac are:
- Lightweight (household and semi-professional) - with a tire up to 45 cm, used in everyday life and for small commercial tasks.
- Professional - with a large saw bar, used for felling forests and preparing lumber for sale.
The main elements that make up the original Italian Oleo-Mac chainsaw:
- A fuel mixture of oil and gasoline (1:50) is poured into the fuel tank (for Italian chainsaws the gas tank volume is 0.23–0.8 l, the largest gas tank for the Oleo-Mac GS 650 and Oleo-Mac GS 720 models is 0, 8 l, the smallest fuel tank is for the lightweight Oleo-Mac 932C chainsaw - 0.23 l).
- The resulting fuel mixture is then taken from the gas tank into the carburetor to be mixed with air.
- The fuel mixture, saturated with air, is pumped into the cylinder of a 2-stroke internal combustion engine, here it is ignited by a spark from the spark plug.
- The engine starts the movement of the crank mechanism, the purpose of which is to convert the reciprocating piston movements into shaft rotation.
- The shaft is connected to a centrifugal clutch with a sprocket that drives the saw chain. This is how cutting occurs using an Oleo-Mac chainsaw.
IN structural device also have:
- cleaning the air supplied to the carburetor
- saw set consisting of a bar and chain
- starter (manual or electric)
- spark plugs
- muffler
- oil tank for automatic chain lubrication
- side chain tensioner
- inertia brake (or, as it is also called, an electric chain brake to prevent kickback).
What is a primer on an Oleo-Mac chainsaw?
It is important for owners to know what a primer is in an Oleo-Mac chainsaw, because, thanks to a manual fuel pump for pre-priming, called a primer or choke, a cooled internal combustion engine starts faster. When starting a gas-powered tool using a primer, it is possible to fill the carburetor with gasoline in advance; without using a primer, it will take more time to pump fuel with the carburetor pump by using the starter. Primers are used for engines after filling with a fuel mixture or for cold engines that have not been used for a long time.
Oleo Mac chainsaw where to add oil?
Chainsaw oil is used in two types:
- Motor oil for adding to the fuel mixture to start a 2-stroke gasoline internal combustion engine. 2-stroke engines do not have an oil sump, so it is necessary motor oil for 2-stroke engines, add directly to gasoline (Oleo-Mac branded oil in a ratio of 1:50 or any other motor oil - 1:40). This is necessary to lubricate the engine in order to avoid unwanted friction and the formation of carbon deposits on the key elements of the motor.
- Oil for lubricating chains is poured into the oil tank (in chainsaws, the tank for chain oil has a volume of 0.13–0.45 l). This is necessary for automatic lubrication of the chain - this way it will last longer. The Italytools online store recommends Oleo Mac Ecolube branded chain oil.

The authorized service center of the official Italytools dealer involves adjusting the carburetor, as well as changing the engine and chain oil, at each maintenance.
Startup problems Oleo-Mac chainsaws
Why won't my Oleo-Mac chainsaw start?
The main reasons why the Oleo Mac chainsaw does not start are sought, moving from simple to complex:
- A banal lack of fuel in the gas tank or insufficient quantity to start.
- Inspect all fuel hoses and connections, pay attention to the crankshaft seals.
- Incorrectly prepared fuel mixture - prepare according to the instructions, use only the brand of gasoline with the appropriate octane number, not higher or lower. Don't forget to add engine oil to the fuel mixture.
- The mixture is made based on production in 1–2 weeks; after this period, gasoline loses its octane qualities.
- During startup, the spark plug was filled with gasoline. It is necessary to dry the spark plug without calcining it, drain off the excess fuel mixture, wait half an hour and then replace the spark plug and repeat the start. It is advisable to have a spare spark plug if drying a gasoline-filled spark plug does not help.
- The problem may be not only in the spark plug, but also in poor contact of its tip with the high-voltage wire. If the contact is normal, but there is no spark from turning on the starter, then the reason is in the electronic ignition unit. Unfortunately, this element is not repairable and needs to be replaced.
- If the tool does not want to start when starting, inspect the spark plug: its suspicious dryness means that there is no fuel entering the cylinder, so the reason may be in the carburetor. The presence of black carbon deposits indicates that an incorrect carburetor adjustment was made, as a result of which the carburetor supplies too much fuel mixture to the air-fuel mixture or there is too much engine oil in the mixture itself.
- More serious reasons you need to look in the cylinder-piston group. Signs are the presence of chips and scuffs on the cylinder and piston. Problems are eliminated by boring the cylinder for a new piston group. You also need to check the piston rings - play when the piston rocks by the connecting rod in the cylinder indicates worn piston rings that need to be replaced.
Why does the Oleo-Mac chainsaw have trouble starting?
Why is the Oleo Mac chainsaw difficult to start? The reason may be that the air filter is clogged with dust.
Why does it stall? chainsaw Oleo-Mac when do you give gas?
Often on the forums of craftsmen you can find attempts to find out what needs to be done when the following problem appears: “Why does the Oleo-Mac chainsaw stall when I press the gas?”
Why does the Oleo-Mac chainsaw stall in this case? It is obvious that the fuel mixture is not flowing well due to:
- Clogged fuel filter
- A clogged jet in the carburetor.
The fuel filter can be checked and cleaned very easily and quickly, and the carburetor jet should be checked at a service center.
If there is a drop in power and the chainsaw stalls at idle, the reason may be a clogged muffler. Cleaning the exhaust channel and muffler from tarry exhaust deposits will help solve the problem.
Problems with working with an Oleo-Mac chainsaw
How to properly break in an Oleo-Mac chainsaw?
One of the frequently asked questions from those who have just bought an Oleo-Mac chainsaw is whether the chainsaw needs to be broken in and how to do it correctly?
The sequence of correct running-in of an Oleo-Mac gasoline saw:
- Make a fuel mixture and pour it into the gas tank.
- Run 5-10 full gas tanks at minimum load. Ideal conditions for this are 2–3 minutes of use at 2/3 of the maximum possible power of the saw, then 15–20 seconds at idle. As a break-in load, combine business with pleasure - cut firewood with a small log diameter.
- Then you need to adjust the carburetor. The Italian corporation Emak, which produces Oleo-Mac chain saws, adjusts the carburetor taking into account the upcoming break-in.
Why chainsaw Does Oleo Mac cut badly?

- While making a cut, the chain got onto a knot or nail.
- The tire was not periodically turned over to ensure that the chain wore evenly.
- During the last re-sharpening, the work was done poorly. This often happens during manual sharpening file Then it is advisable to use a professional sharpening machine.
- Bent tire. Very often this problem occurs during felling. big trees if, when a tree fell, the saw was jammed and the tire was bent. Modern chainsaws have a complex system and consist of several main components, which at times require maintenance and adjustment.
