Every 12 Months (or as needed depending on use)
Lubricate the Head Traverse Screws by applying light
grease either by hand, or a small brush to the points
indicated in the diagram. Move the heads to both
extremes to coat the complete surface of the screws
and inspect them for thread wear.
Apply a light grease on the two (2) Traverse Rods either
by hand or with a small brush to the points indicated in
the diagram. Crank both heads in and out to distribute
the lubrication and to check the head movement.
Inspect the Belts for wear and the proper tension.
The tension should be adjusted to an approximate
1/2” gap between a straight edge placed from the
outside edge of the Idler Pulley to the outside edge
of the Outside Pulley with the pulleys located one
behind the other. Depress the belt halfway
between the two pulleys and measure the distance
between the straight edge and the belt depression.
The belts can be adjusted by loosening the Lock
Nut on the Belt Adjustment Screw located on the
front portion of the Flex Drive Pivot Assembly and
turning the screw clockwise to tighten the belt and
counterclockwise to loosen the belt. After the belt
has been properly adjusted, re-tighten the Lock
Nut.
