INSTALLATION
Unpack your Crusher and set it on a platform in the desired location. Insert the mounting blocks
under each side of Crusher to raise the unit and allow clearance for the ore pan. Securely bolt to
platform. Check the alignment of v-belts from the grooved motor pulley to the flat-faced pulley.
This alignment is critical as it is only the alignment that keeps the belts on the Flat-faced Drive
Pulley. ROTATION IS CLOCKWISE WHEN FACING THE DRIVE PULLEY.
Connect the relay switch to your power source in accordance with the directions enclosed with the
switch. Just above the junction box on the motor is a direction plate indicating the proper wiring for
your current. Connect the Crusher to the relay switch in accordance with these directions.
AGAIN, ROTATION IS CLOCKWISE WHEN FACING THE DRIVE PULLEY.
The magnetic starting switch has internal overload protection. This shuts off the current
automatically should the Pulverizer jam through improper adjustment of the plates or the
introduction of foreign matter into the grinding chamber. Should an overload occur, wait a few
minutes to permit the relay to cool and then press the RESET button.
The jaws are preset at the factory to a gap of 1/32". Before starting the crusher for the first time,
the gap should be checked to see that this space has not been altered in shipping or setting up the
machine. A tighter gap could result in damage to the machine.
The crusher can be adjusted by loosening the jam nut and setscrew on the left hand side and
turning the adjusting screw on the right side of the machine. Turning the flywheel located at the
right side of the machine to the left or right will open or close the space between the lower parts of
the jaw so as to give the required crushing size. DO NOT SET THE JAWS TIGHTLY TOGETHER
as this will result in damage to the machine (minimum allowable opening is 1/32 inch on forward
stroke of movable jaw).
ADJUSTMENTS
Heavy bronze bearings are sealed against dust and dirt, and are lubricated by grease cups
so that no special greasing tools are required. To tighten the bearings, loosen the two square
headset screws (behind the cap) a fraction. Turn the four hex-head bolts down a fraction at a
time. Check tightness by turning the pulley or flywheel by hand. There should be a very slight
drag. To loosen, reverse the procedure. Bolts must be tight, but not too tight. USE EXTREME
CAUTION AS OVER-TIGHTENING THE SQUARE OR HEX HEAD SCREWS WILL BREAK THE
CAPS. The caps will radiate some heat, which is normal. Bearings should not be run loose or
excessive wear will result on the bearing, shaft, etc. Check the bolts on a regular basis, as the
machines vibration will have a tendency to loosen the various bolts.
