FILLER PUMP FILLING FROM A BULK CONTAINER (FIG. 5, 6, 9) This tool comes with a 1/8" NPT fill port FIG. 9 (Z, Fig. 5) for attaching a low pressure fill coupler onto the unit. WARNING: Never thread a highpressure coupler onto the grease gun's 1/8" NPT fill port. Serious injury may occur due to excessive pressure. Use low-pressure couplers only. CAUTION: The fill pump loader must connect correctly with the grease gun's 1/8" NPT port. The filler pump may not operate if the components are not compatible. Installing the low pressure coupler (not supplied with the tool) 1. Thread the grease tube assembly (N) back into the grease gun and screw it in securely. 2. Pull the grease tube handle (L) out as far as it will go, then secure the grease tube rod (M) into the retaining slot (O) by moving the rod to the side. Ensure the rod is placed securely in the slot to prevent it from disengaging. 3. Remove the 1/8" NPT fill port plug (AA) from the fill port. 4. Thread the appropriate low pressure coupler onto the 1/8" NPT fill port (Z). 13 English
