1.
Park the machine on a level surface, stop the engine,
and remove the ignition key.
2.
Remove the oil-level plug on the crankcase (
•
If oil drains from the oil-level hole, insert the
oil-level plug.
Note:
The oil level is sufficient if oil drains from
the opening, or is at least at the level of the oil-level
plug.
•
If oil does not drain from the oil-level, or is not at
the level of the oil-level plug, insert the oil-level
plug, and open the oil-filler cap to add the specified
oil.

and add the necessary amount of oil.
Changing the Drilling-fluid-pump Oil
Service Interval:
Every 500 hours—Change the drilling-fluid
pump oil.
1.
Park the machine on a level surface, stop the engine,
and remove the ignition key.
2.
Allow the engine to cool.
