Snow Blowers

Hello;

I bought a Poulan Pro Snow blower model PR624ES and according to the Manual I received, the snow blower has 2 grease zerks that needs greased after 25 hours of use on the auger shaft. I called the Husqvarna Help Line telephone number and the agent looked into the drawings also and said he didn't see any place to grease any zerks either.
Can you tell me if this has any zerks hidden or how would the best way to grease the auger shaft?

thanks, Paul in Russia
