MAINTENANCE

LUBRICATION

During normal operation, gear case oil may require changing due to condensate mixing with the oil. Gear case oil that has mixed with condensate water will have a milky brown color. If this is present, the oil should be replaced.

To change the gear case oil, place a suitable catch pan under the machine and remove the Drain Plug (Fig. 3 or Fig. 4). When old oil is completely drained, replace the Drain Plug. Fill the gear case with

21fluid ounces of Mobilgear 634 as follows: Remove the Plug Button (Fig. 3 or Fig. 4); then remove the Plastic Oil-Fill Plug (Fig. 6). Pour the proper amount of Mobilgear 634 into the elbow. The gear case is full when the oil is at the bottom thread level of the elbow (Fig. 6). Thread the Plastic Oil-Fill Plug back into the elbow, finger-tight. Press the Plug Button back into the hole of the chopper housing. The chopper requires no other lubrication maintenance.
