I need information on the mac 5 evolution chainsaw ie what petrol it uses also what do you put in the small tank

if no gas will enter priming bulb at all I see only a few possible things for this
(1) gas line broken/melted
(2) filter looks good but has internal plug
(3) primer bulb has a small crack in it (most common )

Yes. You need to purchase two-cycle oil and mix it with petrol according to the chainsaw manufacturer instructions (this information is in the manual). It will specify the appropriate mix for your chainsaw.

You may contact the manufacturer, download manuals, check fuel/oil ratios, order parts, find your local service center, and view other resources using these links:

I trust this information has proven beneficial.

You should run the saw on a 50-1 fuel oil mix, with an oil from a known chainsaw manufacturer and recommended for 50-1, this machine was an Italian built product sold under many different model names, Titanium 460,Partner 538, California, i am sure if you surf the net you will find one. If you cant find one post me your e mail address and i will send you one.

fuel mix ratio is 50:1 using good quality 2 stroke oil

ie if you mix 20 mils of oil for every 1 litre of petrol that you mix
that is 50:1

or if you want a 5 litre mix put in 100 mils of oil into a clean petrol container 1st then put in 5 litres of fuel only and give good shake

cheers paul

using good quality 2 stroke oil use ratio 50:1

that is 20 mils of oil per 1 litre of petrol that you mix

put oil in can 1st then add petrol and give good shake

so if mixing 5 litres pour in 100 mils of 2 stroke oil and add 5 litres of fuel only

cheers hope it helps

• One line should be hooked to a small fuel filter or screen.
• The other one is a dump or over flow that will put a small amount of unused fuel back into the tank.
• You can buy this type of line at most Lawn Mower shops as a kit. 2 lines and a filer/screen.
• You can use line for air shocks that fit some cars ie. Cadillac's

50:1 =:
1gallon premium fuel to 2.6 ounces of quality 2-cycle engine oil
4 liters premium fuel to 80CCs of quality 2-cycle engine oil.

I have a parts manual you can have a copy, can you tell me what the gas mixture for the Oleo Mac 234f, 25:1 or 50:1

Put some fuel (1/2 tank) in the fuel tank, replace fuel cap and shake chainsaw. Empty this out and refill with fresh fuel (mix), Make absolutely sure to cleanup any spillage, it should be fine after that.
