S RUCTIONS FOR THE CARE ANO TION OF THE JOY CLASS - O IR WINCH IPTION JOY Rock Orill Oils NO.l0 and NO.50 conform to the above specilications. NO.l0 is used when ambient ternoer- atures are below Ireezing and NO.50 is used when ambient temperaturas are above freez inq, Gesr Housing. The gear housing is serviced at the lactory with grease and, based on interrnittent service, requires regreasing only at normal overhaul periods. If it becomes necessary to add grease before overhaul, add grease through th~ pr~re grease fitting (see Fig. 2). Do not overgrease; this wlll. cause leakage 01 grease around the drum Ilange.

Alter assembly is completed, service rhe gear housing with grease through the pressure grease fitting. One lb. 01 grease is sufficient lor correct lubrication of sil gears and bearings. OPERATION Before Operetion. Blow out the air hose before attaching to the air inlet on the Pistonair motor. Pour a small amount 01 rock drill oil into the hose be lo re attaching 10 the air motor. This assures immediate lubrication of working parts 01 the motor. Air pressure should be 80 lbs. per sq. in. et me mectiine. Operating Controts.
