VM Series Maintenance and Safety Manual 704-0212-209 Machine Maintenance 3- 7
Maintain Autolube Filler Filter Screen and Autolube Fluid Level
Monthly: Maintain the autolube fluid level and check the filler filter screen.
The filter screen inside the oil filler section of the tank prevents contamination from
entering the system. The filter screen must be checked and replaced if it becomes
plugged. The autolube oil must be replaced monthly.
1. Lift the oil filler cap and check the filter screen. If the screen is dirty or
clogged, clean and dry the screen before reinstalling it.
2. The oil level should be between the high and low marks (about 1/2 inch or
1.25 cm from top cover of tank). If needed, add oil to the tank. Refer to Table
3–1.Lubrication, on page 3 - 5 for oil type.
3. Replace the oil filler cap.
Adjust Autolube Discharge Rate
An indicator rod is located in the Autolube system discharge chamber. The scale
graduations on the flat surface of the rod indicate the discharge rate in cubic centimeters
(cc) per pump cycle. Follow these steps to adjust the Autolube system discharge rate:
1. Loosen (but do not remove) the set screw in the center of the discharge
plunger body.
2. Turn the plunger body clockwise to increase, or counterclockwise to decrease,
the pump discharge rate.
3. Once the required discharge rate is obtained, align the set screw with the flat
surface on the rod.
4. Tighten the set screw to secure the rod position.
Excess Servo On time without table or head movement may cause oil
to accumulate on the table and guideways. To eliminate excess
lubrication, the Power Off Timer can be set to automatically shut off
power to a machine that has been idle for a specified time.
Monthly: Add a rust preventative to the Autolube system if the
machine will be idle for 30 days or more.
Initiate a manual lube cycle and move all axes through full travel
several times to allow delivery of the rust preventative throughout
the system.
Refer to Table 3–1.Lubrication, on page 3 - 5 for more information.
If the level of way lube becomes low, a message will appear on the
screen.
