Finally, I got my WD45 running and blading snow. Went to check the hydraulic reservoir, and there was barely any oil on the stick! I would like to change the remaining oil out and put in new. My questions are:
1. My owners manual says to use a "magnetic drain plug at the bottom of the housing" and "to completely drain the pump, the pump housing must also be drained". First of all, where are these located and what do they look like (the manual has no pic's of them)? Secondly, do you really drain two things or does it just sound that way? Finally, how do you know you when you have all the old oil out?
2. My IT Manual talks about bleeding the system using the gland nuts on the rams. Is this necessary? The owner's manual doesn't mention this.
3. Anything else I should know so as not to damage the system?
