My 2001 SL20 is throwing a 134 alarm, stating my Hyd pressure is too low. I know its not supposed to get below 100psi, but Im running it at 300. This just started today, and I have never encountered this before with our sl20's. It works for 6 to 8 open and closings, then alarms out. I can reset it, but only get a few more before it repeats. The oil level seems fine, looking thru the top of the tank, because my level isnt working properly.
This may sound stupid, or not, but I have never changed this oil out. The manual states it is supposed to be changed every 24 months. It doesnt appear to have any leaks, and the level has remained the same since I bought it new.
Im going to change the oil right now, and clean the heat exchanger on the top of the motor. Is there any other suggestions you folks would have??? It doesnt appear to be electronic, or it wouldnt work at all. Is it possible for the oil to be too thin with age and heat? The tempurature, if correct,(since the level doesnt work properly, I cant say if the temp is right), is around 115.
Thanks in advance for your replies,
