* Note: Gearbox and lead screw lubrication: Lubricate the vise lead screw and gearbox with Shell Omala S1W
or its equivalent.
The gearbox gears run in an oil bath and will not require lubricant change more than once a year unless the
lubricant is accidentally contaminated or leakage occurs due to improper replacement of the gearbox cover or
gasket. During the first few days of operation the drive gears will run hot. Unless the temperature exceeds 200
degrees F., there is no cause for concern.
