Pay attention to the dustproof work in the working
environment. The #20 machinery oil should be applied to the shaft to
keep a certain film of oil on the working surface. The running
part of the reversal springs should be lubricated for protection.
In case the reversal is too show or not available,
push and check the reversal arm for swivelling blockage so as to
eliminate the fault. If the elasticity is insufficient, change the
reversal spring and lubricate the bearing point of spring.
Adequately screw clockwise the screw plugs in the
center of the top and/or in the side edge of the bottom of the drive
housing until the traverse thrust required is available. Too
tight adjustment of screw plugs often causes improper reversal and
may lower the operating life of the drive unit.
The eccentric sleeve on the back side wall of the
housing is required. It is usually fastened by set
screws. Loosen the screws first to make a slight adjustment,
and screw them tight again after the left-handed and right-handed
travel pitches are identical.
