Hydraulic fluid straight from the drum, has a typical cleanliness level of ISO 4406 21/18.
A 25 GPM pump operating continuously in hydraulic oil at this cleanliness level will circulate 3,500 pounds of dirt to the hydraulic system's components each year!
To add hydraulic oil, and not the dirt, always filter new oil prior to use in a hydraulic system.
This can be accomplished by pumping the oil into the hydraulic reservoir through the system's return filter. The easiest way to do this is to install a tee in the return line and attach a quick-connector to the branch of this tee. Attach the other half of the quick-connector to the discharge hose of a drum pump.
When hydraulic oil needs to be added to the reservoir, the drum pump is coupled to the return line and the oil is pumped into the reservoir through the return filter. As well as filtering the oil, spills are avoided and the ingress of external contamination is prevented.
The benefits of carrying out this simple modification are well worth the minor cost involved.

FIRST it depends on the model Machine most cases its difficult and only left to replace the complete switch because there is inside OR OUTSIDE the switch a mosfet used look right corner downunder the photo how it looked always this mosfet is mounted with a screw on a heatsink if its insite the switch the heatsink is long and on the switch heatsink is outside the switch on if its outside replace the yellow , blue and black cable as its mounted if all black wires then look of the model code name of the mosfet where gate , drain and source are on the wires . in most case the mosfet has sometimes not a standard code to get from Ebay or a shop and also not to get by the importer.
The TE-70 is permantly lubricated. You would only add lubricant if you took the tool apart. You can add a small amount of grease to the end of your bit occasionally before putting in the chuck. This keeps the chuck parts lubed.
the only way (without harm the armature) is to use a bearing puller or the bearing press with the separator. maybe u can loan it from autozone of advance auto parts, cause is a common tool among car mechanics.
You should never provide more voltage to a tool or motor than what it is designed for. So, as a result, I would advise strongly against it. You have the chance of frying circuits and capacitors very easily by doing so.
On the flip side, using too low a voltage will also result in motor damage. Stick with an 18v battery for an 18v drill.

High pressure fluid is present in operational hydraulic systems. Fluids under high pressure are dangerous and can cause serious injury or death. Do not make modifications, repairs or adjustments to any hydraulic system unless you are competent or working under competent supervision. If in doubt consult a qualified technician or engineer.
Before connecting a drill press to a power source be sure that the voltage supply is the same as that specified on the nameplate of the tool. A power source with a voltage greater than that specified for the tool can result in serious injury to the user, as well as damage to the tool. Using a power source with a voltage less than the nameplate rating is harmful to the motor. Also, when operating the drill press, use safety equipment including safety goggles or shield, ear protection and protective clothing including safety gloves; Keep the area free of tripping hazards; Periodically check that all nuts, bolts and other fixings are properly tightened; Never use your hands to remove dust, chips or waste close by the drill bit.
