Swing Reducer
MAINTENANCE CHECK
1. On a WEEKLY basis, check the swing reducer oil level and add oil as needed to
maintain the level at the "FULL" showing in the sight glass window as indicated below
in the image. Recommended lubricant is AGMA #4EP Gear Oil or equivalent.
2. All swing drive gearboxes from Terex are shipped with an additive to the gear oil of 5
oz (148 ml) of ethylene glycol for cold weather protection. If gear oil in the unit is
changed, Terex recommends the same amount of ethylene glycol is added to prevent
freeze up of unit due to internal condensation.
