relubricating power tools - what oil to use?

[spyghost]

hi,

i've got some power tools that have been sitting lately unused. i checked on them and found out that oil was leaking out of the housings. they were still working though. i just wanted them lubricated. i'm planning on openning the housing and re-lubing the parts.

any idea what oil to use? i am planing to use an sae90 gear oil.

btw, the tools are bosch drill and jig saw, and makita cordless drill/driver.

I once had a chance to open up a Makita cordless drill to repair the cut off switch. Lubrication inside is grease. Looks to me like regular grease but somewhat heavier than the ones sold by the local gas stations.

if it were grease, then what kind of oil was it that dripped when the tools were on the cabinet for quite sometime. i traced it and i was certain that it came from the inside of the power tools. it felt like oil and it smelled like oil.

well old grease that has melted over time will look like oil and smell like oil as well. Unless its an engine, don't use oil on it. electrical parts don't react well with oil. the property of grease being solid makes it great for these applications. But if you want to use oil, Go ahead. Its you tools anyway.
