Model 230B Lifting Frame

92-1052 : Orig. 021204

MAINTENANCE

Cleaning

The lifting screw surfaces should be inspected periodically for contamination from
metal chips and debris. Any contamination should be removed immediately to pre-
vent damage to the screw and nut.

Lubrication

The lifting screw must always be kept well lubricated with a quality EP grease such
as Chevron Ultra Duty Grease EP, NLGI 2. The gearbox of the 230B rotator mecha-
nism must be maintained full of Mobil SHC 634 Bearing and Gear Oil, ISO VG 460,
or equivalent.

Belt Tension

Belt tension should be checked periodically and adjusted as needed to maintain
about a 1/2" belt deflection when 10 pounds of force is applied mid-way between the
pulleys. When adjusting the belt tension it is important to adjust both the upper and
lower tensioning bolts equally to keep the pulley shaft perpendicular to the frame.
