nstructions are provided with each speed reducer . These instructions should be followed for best results . It is important that the correct types of oil be used since many oils are not suitable for the lubrication of gears . Various types of gearing require different types of lubricants . The lubricant must remain free from oxidation and contamination by water or debris, since only very thin film of oil stands between efficient operation and failure . To assure long service life, the reducer should be periodically drained (preferably while warm) and refilled to the proper level with recommended gear oil .Under normal environmental conditions oil changes are suggested after the initial 2 hours of operation and thereafter at regular intervals of 2 hours or every 6 months . Synthetic lubricants will allow extended lubrication intervals due to its increased resistance to thermal and oxidation degradation . It is suggested that the initial oil change be made at 1 hours and, thereafter, at 5 hour intervals . During the initial period of operation, higher than normal operating temperatures may be seen . This is due to the initial break-in of the gear set . The temperature of Single Reduction Worm Gear Reducers may reach approximately 2F .

High loads and operating temperatures will also require the use of frequent lubrication . * Synthetic recommendation is Klubersynth UH1 6-4, other lubrications may reduce efficiency and torque capacity . + Other lubricants corresponding to AGMA/ISO numbers are available from all major oil companies .
