The unit is elivere lubricate with KLUR SOLX TOPS NL grease type, (N ). When using the unit at high spees choose type 1, an for heavy loas type. ontinuous lubrication is not avise because the alternating motion eposits too much grease on the screw filling the spinle tube an reucing the available stroke together. There will also be an increase in temperature
