753L snow blower wont stay on

[aczr800]

I have a 753L went to use blower for first time and it wont stay engaged unless I hold the thumb toggle on the right lever to the left, haven't used it in two years but if I recall the right trigger switch would lock the blower on, when I hit the right trigger the blower starts moving backwards very slowly, if I remember correctly the right toggle would also reverse the blower when toggle was moved to right, it does nothing when moved to right, I used it to blow snow by holding the right toggle on but that's kind of a pain when trying to turn and tilt auger my grapple bucket worked on it this fall, I had steam cleaned the machine earlier, was thinkin maybe got moisture in a connection, have had it in heated shed for couple of days and checked all connectors, any help would be appreciated,

The blower should run correctly by hitting the trigger with your pointer finger on the front of the right handle. If it runs backwards, your couplers on your snowblower are on backwards.

When hitting the right trigger the blower does start turning very slowly backwards you can stop it from turning its like its not getting full flow, the couplers haven't been changed or moved so I assume there correct as it worked last time we had snow

Press the Auxiliary Hydraulics button 2 times to activate Continuous Flow, then press and release the Trigger on the Right Handle.
