MAINTENANCE
It is of the greatest importance that the crusher is kept properly lubricated at all times (use
any good quality hi-temperature grease. We use a lithium-based grease). Turn down the grease
cups 1/4 of a turn at least once a day, or more if the machine is in constant use. This will protect
the bearings. Oil the adjusting blocks and toggle block approximately once a week. An oil cup is
provided for this purpose at the front of the spacer casting and at the rear toggle block.
When the plates are worn to a point where readjustment is necessary, they can be
adjusted. To do this simply insert the set of shims provided with each crusher between the jaw
and jaw plate. This will compensate for wear.
For still further adjustment, and for resetting the adjusting blocks, loosen the small
setscrew at the left side of the crusher. Turn hand wheel to the right, which will allow the adjusting
block to move forward.
