IMPORTANT GROUNDING INSTRUCTIONS
If electrical tesng is required, always verify the machine has a proper ground before performing any tests.
In case of a malfuncon or breakdown, grounding reduces the risk of electrical shock by providing a path of
least resistance for electrical current.
This Grinder has an electrical cord with an equipment grounding conductor and a grounding plug. The plug
must be plugged into a matching outlet that is properly installed and grounded according to all local or other
appropriate electrical codes and ordinances.
Before plugging in the Grinder, make sure it will be connected to a supply circuit protected by a properly-sized
circuit breaker or fuse. SEE SERIAL NUMBER PLATE FOR FULL LOAD AMP RATING OF YOUR MACHINE.
Never modify the plug provided with the machine--if it won't t the outlet, have a proper outlet and circuit
installed by a qualied electrician.
ALWAYS PROVIDE A PROPER ELECTRICAL GROUND FOR YOUR MACHINE. AN IMPROPER
CONNECTION CAN CAUSE A DANGEROUS ELECTRICAL SHOCK. IF YOU ARE UNSURE OF THE
PROPER ELECTRICAL GROUNDING PROCEDURE, CONTACT A QUALIFIED ELECTRICIAN.
UNPLUG THE EQUIPMENT PRIOR TO DOING ANY SERVICE ON THIS EQUIPMENT. FAILURE TO
REMOVE POWER TO THIS EQUIPMENT BEFORE SERVICING MAY RESULT IN INJURY OR DEATH.

LUBRICATION
LUBRICATION OF GRINDING SHAFT AND LINEAR BEARINGS
STEP 1 – Thoroughly clean all three shas.
STEP 2 – Flood spray all three shas with CRC 3-36 unl the lubricant is dripping o the shas. Do not use
a teon-based lubricant. Then run the grinding head assemblies back and forth through their full range
of travel. This will remove the dust and deposits from inside the wheel anges. Repeat if necessary unl
lubricaon is clear of deposits. Clean keyways located on the grinding sha with so brush.
STEP 3 – With a clean rag, wipe o the excess amount of lubricant from the shas. Run the grinding
assemblies through their range of travel and wipe the shas aer each traverse. Repeat unl the shas are
dry to the feel. This completes the lubricaon process.
IMPORTANT:
If the unit will be shut down for an extended period of me, more than four weeks, then the shas and other
appropriate parts of the unit should be ooded with lubricant and that lubricant le in place unl the unit is

MAINTENANCE
REPLACEMENT OF GRINDING WHEEL
To replace the wheel, rst open the le side hinged
panel and remove the lower le side cover panel.
Then, lower the le side of the grinding sha and
raise the right side. Next, loosen the two bolts that
hold the bearing bracket on the relief hub so that the
bearings pivot away from the wheel and hub (toward
the front of the machine). See FIG 5. Press the index
nger down and the wheel and hub assembly should
move freely to the right.
To remove the le side bearing: rst, loosen the
setscrews on the bearing collar, then remove the four
screws that hold the bearing to the le arm.
Slide the grinding wheel hub assembly(s) o the
sha, taking note of what side the nut is on. Use the
spanner wrench to remove and replace the grinding
wheel(s).
NOTE: THE RELIEF HUB HAS A LEFT HAND
THREAD FOR THE NUT. THE SPIN HUB HAS A RIGHT
HAND THREAD.
Place the grinding wheel hub assembly(s) back on
the grinding sha. Verify that the spin hub is located
between the spin drive yoke assembly and the relief
hub is to the right of the relief drive assembly before
lowering the grinding sha.
MAKE SURE THE WHEEL(S) IS PLACED
ON THE SHAFT WITH THE SAME ORIENTATION AS
SHOWN. FAILURE TO INSTALL CORRECTLY WILL
CAUSE THE WHEEL NUT TO LOOSEN. (THE NUT ON
THE RELIEF HUB SHOULD BE TO THE RIGHT & THE
NUT ON THE SPIN HUB SHOULD BE TO THE LEFT.)
Reinstall the bearing on the le side of the grinding
sha making sure to t the pilot on the bearing into
arm. Tighten the four mounng screws, and then
ghten the setscrews to the sha. Reinstall the le
side cover panel. Move bearing support bracket back
into place. See relief hub bearing adjustment to set
the bracket correctly.
