Important Safety Instructions
Read all warnings and instructions in this manual and manual 309015.
See manual 309015 for Automatic Lubrication System installation,
operation, and troubleshooting. Save all instructions.
SKIN INJECTION HAZARD
Fluid from the injector, leaks, or ruptured components
can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid
injected into the skin might look like just a cut, but it is a
serious injury. Get immediate surgical treatment.
Fluid splashed in the eyes or on the skin can also
cause serious injury. The equipment may be pressurized already, or it could become pressurized by an
automatic lube cycle initiated by Lubrication Controller
(timer). Disconnect power to the timer, and disconnect
the air supply to the pump module to ensure that the
system is depressurized. See the pressure relief pro-
cedure in Pump Module manual 308955.
