Maintenance
1. Pull out the dipstick and wipe off with a lint-free,
clean cloth.
2. Insert the dipstick into the engine again as far as it
will go.
3. Pull out the dipstick again and read the oil level.
The oil level must always be between the MIN and
MAX marks. Add oil up to the MAX mark if
necessary.
Checking the Pump Level Sight Gauges
Check that oil is visible in the sight glass for the mechanical
seal and bearing frame. (It is recommended that the sight
glasses be checked daily.) If no oil is visible, oil will need
to be added.
Adding Oil:
1. Shut down the unit.
2. Remove the air breather in the bearing frame and
add oil until halfway up the sight glass (gauge).
3. Remove the air breather in the mechanical seal
and add oil until halfway up the sight glass (gauge).
NOTE: Keep dirt and moisture out when adding oil. DO
NOT OVERFILL.
4. Install the air breather.
Draining Oil
1. Shut down the unit.
2. Place a suitable container under the mechanical
seal and bearing frame drain plugs.
3. Remove the mechanical seal and bearing frame
drain plugs.
4. Drain the oil completely.
5. Install the seal and bearing drain plugs.
6. Follow the instructions above for adding oil.
Changing the Engine Oil
1. Warm up the engine (oil temperature greater than
176 °F (80 °C).
2. Verify the engine is in a level position.
3. Turn the engine off.
4. Place a collecting receptacle underneath the lube
oil drain.
5. Open the oil drain valve and drain the oil into the
receptacle.
6. After the oil has drained completely, close the oil
drain valve.
7. Remove the engine oil fill cap and add the
recommended amount and type of oil. Refer to the
engine manual for specifications.
8. Warm up the engine (oil temperature greater than
176 °F (80 °C)).
9. Verify the engine is level and check the oil level.
Refer to Checking the Engine Oil.
Changing the Oil Filter
NOTE: The filter cartridge should never be pre-filled.
There is a danger of dirt contamination.
1. Loosen and unscrew the filter with filter tool. Refer
to engine manual for more information.
2. Collect the draining engine oil.
3. Clean the sealing surface of the filter support with a
lint-free, clean cloth.
4. Oil the gasket of the new filter cartridge lightly.
5. Screw on the new filter by hand until the gasket is
touching and then torque to 11-13 ft-lbs (15-17
Nm).
Adding Coolant
1. Visually check the coolant level in the sight glass
located near the top of the radiator. If coolant is not
visible, coolant will need to be added to the sys-
tem.
2. Let engine cool (not at operating temperature, not
running), before adding coolant.
3. Add a 50/50 mixture of the correct antifreeze and
distilled or deionized water to the coolant system.
Add until it is 3/4 in. (19 mm) below the filler neck.
