To reduce the risk of fire or explosion that can result
from static sparking or chemical incompatibility:
• Verify that the hose lubricant is compatible with
your pumped fluid. Do not use glycerin hose
lubricant if pumping strong oxidizer or acids.
• Keep the pump properly filled with genuine
Graco hose lubricant.

The vent and drain port threads are aluminum. To
help prevent galling, inspect the bolt threads for
foreign material and clean or replace if necessary.
1.
Wrap the drain plug (29) threads with PTFE tape
and install the plug into the bottom cover port. Be
sure that it is tight to prevent leakage of lubricant.
2.
Use a funnel with a flexible spout to add hose
lubricant through the vent port. The lubricant
level must cover the bottom of the roller.
NOTE:
NOTE:
NOTE: If you are using the optional leak sensor,
overfilling may cause nuisance tripping of the
sensor.
See the following table for the correct amount
of lubricant for your pump. Pre-measuring the
correct amount will help prevent overfilling.
