MSD SABER SERIES SHEARS
SLIDE SCREW MAINTENANCE
Maintenance of the slide screw area is very important for keeping the cutting blades in line and for proper
operation of the shear. This critical area should be inspected and adjusted every 80 hours. Use the following
instructions to maintain and adjust the slide screw.
1. See Figure 5-3 . To check and/or replace the slide screw, remove the bolts and lock plate (see Figure 5-5 ,
page 5-13). Use a crescent wrench on the square end of the slide screw and turn it clockwise to adjust,
counterclockwise to remove.
2. Look at the face of the slide screw to determine if there are still grease grooves (see Figure 5-4 ). If the
grease grooves are worn away, it will be necessary to replace the slide screw. If the slide screw needs to be
replaced, continue on with step 3.
3 . To remove the slide screw, turn counterclockwise and back it completely out. To adjust the slide screws,
cycle the upper jaw until the slide screw is centered on the wear plate. Clean the inside threads, if neces-
sary, and thread in the new slide screw until it just makes contact with the wear plate (both sides). Re-
install the lock plate and lock bolts, and lock the adjusted slide screw into position.
4. Apply grease to the entire assembly through the grease fi tting in the slide screw. Also, apply a layer of
grease to the rear wear plates on the upper shear with a brush or grease gun. Do not apply grease by hand!
5. It is recommended that the slide screws be completely removed every 80 hours of operation, the threads
(both internal an external) be cleaned, and then coated with 2-EP Lithium grease. Failure to do so will result
in the slide puck jamming and becoming ineffective.
Keep clear when the shear is in motion. Avoid
pinch points, such as the upper shear or the
shear cylinder, or severe injury could result.
DO NOT cycle or move the shear while unthread-
ing the slide screw by hand. This will result in
severe injury.
