Rear Rachet Pawl should
become engaged at between
3” to 4” of elevation
3½” = Optimal Setting
in most instances
Step 1: On a flat and level surface, unhitch the spreader from its
towing vehicle.
Step 2: Adjust front tip stand so unit is in a reasonably level position.
Step 3: Inspect cam follower roller (Item 32), shown in Detail C, and
replace if worn.
Step 4: Raise handle (Item 16), shown in Detail B, on floor chain
drive mechanism side only, to its full upright (engaged) position.
Step 5: Roll spreader slightly, a few inches should do the trick, either
forward or rearward until the cam follower roller resides at its lowest
point on cam (Item 34), shown in Detail C. See Figure 1.
Figure 1
Step 6: At this point block both wheels, front and back, to secure the
spreader in place.
Step 7: Using a needle nose pliers, unseat the lower end of the 6”
spring (Item 46), shown in Detail C, from its vertical mounting brack-
et.
Step 8: Remove left side shield (Item 48), shown in Detail D. Set
shield and hardware off to the side for the time being.
Step 9: Next, slowly lift the cam follower roller (Item 32) upward until
the rear ratchet pawl engages. The instant the rear ratchet pawl be-
comes engaged, a reasonably loud “click” should be heard. Refer to
Figure 2.
Figure 2
**NOTE** It is crucial that the lifting of the cam follower roller is
stopped the very instant the rear ratchet pawl becomes engaged, in
order to provide an accurate reading for set-up. If you happen to go
too far, simply push the cam follower roller back down into its lowest
position and lift again slowly.
The optimal setting most instances is 3½”, depending upon the
spreader’s age and wear pattern.
Step 10: If the rear ratchet engages too quickly or does not engage
soon enough, it is out of phase and must be repositioned.
Step 11: Repositioning of the rear ratchet pawl is accomplished quite
simply by loosening the rear ratchet pawl adjustment bolt and moving
it either up or down with the ratchet pawl adjustment slot and then
retightening. Refer to Figure 3.
Some trial and error may be involved in this process, as every
spreader will require slightly different settings to achieve proper lift
distance of the cam follower.
Step 12: Re-attach the 6” spring to its vertical mounting bracket, as
well as the left side shield, prior to testing.
Step 13: Test empty spreader at a reduced speed for a period of time
insuring the floor chain drive mechanism is running smoothly.
Step 14: Place back in service.
