Holes drilled in the piston carry oil from the bottom of the rammer tothe crankcase as the rammer operates. Oil in the ramming system must bemaintained at the correct level to ensure that the ramming system operatesefficiently.Checking theoil levelPerform the following procedure to check the ramming system oil level.Note: If the rammer has been transported in the horizontal position or has recentlybeen used, place it upright and allow it to stand in the upright position for 15minutes before checking the oil level. This will allow the oil to settle and provide amore accurate reading.1. Tip the rammer so that it is perpendicular with the ground.2. Check the oil through the sightglass (a).The correct oil level will fill 1/2 to 3/4 of the sightglass. Add more oil if necessary.Adding oil Perform the following procedure to add oil to the ramming system.NOTICE: Do not overfill the ramming system with oil. Excessively high levels of oilcan create a hydraulic lock in the ramming system. This can result in erraticoperation and cause damage to the engine clutch, the ramming system, and theshoe.1. Tip the rammer forward to allow access to the sightglass. Secure the rammer inthis position.This procedure continues on the next page.
