INSTRUCTIONS for Properly Feeding the Chipmunk Jaw Crusher 

*NEVER OPERATE ROCK CRUSHER WITHOUT SAFETY GUARDS PROPERLY IN PLACE OVER PULLEYS AND FLYWHEEL*

Once properly mounted to a stand, and with safety guards in place your Rock Crusher is ready to begin crushing rock. Adhering to the following steps will yield the best results:

  1. Before turning on Rock Crusher, make sure jaws are free of debris.
  2. Plate collecting bucket or trough underneath dispensary area of rock crusher to catch particles.
  3. When Rock Crusher is running, feed rocks with a maximum size of 3/4” into top of Crusher. Do not over feed Rock Crusher, for best results allow only half the jaw area to be filled with rock at one time. Do not fill crusher right up to top of the jaws, this puts too much pressure on jaws and can damage bearings.
  4. Speed and Particle size are a factor of how the lower jaw width is set. Read how to adjust dispensary particle size in order to make changes. Smaller Particle size the longer it will take the Jaw Crusher to work through rock, the Larger the particle size setting, the faster the jaw crusher can work through rock.

  • Rock Crusher should be used outside, or, in properly ventilated area.
  • Rock Crusher is designed to be used by adults. Parental supervision is needed for operators who are under the age of maturity.

Adjusting Jaws allows you change the ways the Crusher Jaws perform for different rocks and output requirements.

Adjusting Dispensary Particle Size can be done by adjusting the HEX nut on the back of the crusher between the crusher and engine.

To DECREASE particle size: Use ½” wrench to turn hex nut clockwise (Towards Pulley). Be aware of centric bearing position when measuring jaw opening.

Jaws should never run in contact with one another.

To INCREASE particle size: Use ½” wrench to turn hex nut counter clockwise (Towards FlyWheel). Be aware of centric bearing position when measuring jaw opening.
