excavator maintenance?

[thebigo]

Thanks a bunch for the detailed info!!! Joe where did you get your pressure guage, and can I just get 10w Hydr oil at the parts store? I have latey been running at about 50 degrees? We are kinda ignorant down here, for the last 50 years we still havent brought ourselves to go to the Metric system. Motocrawler gave me Beswik for a filter and guage supplier, but they have several diffrent kinds of fittings with different pressures not sure what mine is and dident find a guage yet? Probably need to look harder on that WEB site?
