Connecting Cooling Pump - Grizzly G0931 Owner's Manual

Connecting Cooling
Pump
The Model G0931 includes an external pump that
cools the spindle motor. Coolant tubes come pre-
installed on the motor and run through the cable
carrier. The tube must be connected to the pump
and submerged within a coolant reservoir.
A minimum of 4 gallons of water is required for
normal operations. Hot conditions may require
more coolant. If environmental temperatures are
below freezing, 50/50 anti-freeze must be added.
Operating the router without the cooling
pump may damage the internal components
of the spindle motor.
