4. Ensure that the oil is at the oil-fill line as shown in
Figure

of
Changing the Drilling-Fluid Pump Oil (page 87)
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. Open the rear hood.
3. Allow the engine to cool.
4. Remove the drain plug and place a drain pan under the

Preparing the Drilling-Fluid
System for Cold Weather
Prepare the machine as follows after drilling if the temperature
will be below 0° C (32° F).
1. Park the machine on a level surface, stop the engine,
and remove the ignition key.
2. Prepare the machine to circulate the antifreeze as
follows:
A. Open the rear hood.
B. Place a drain pan under the drill spindle for the
leaked antifreeze
