EYESHIELDS
WARNING!
Never operate grinder with eyeshields removed.
Position the eyeshields so that manipulation of the work piece to the grinding stone is not
obstructed by the shield and that the piece of work is between the stone and the eyeshield.
SPARK DEFLECTORS
•
Adjust periodically to insure that the distance between O.D. of the stone/wire wheel and
the bottom edge of the spark deflector is
1
/16" clearance.
• Insure screws are securely tightened.
TOOL RESTS
•
Keep tool rests adjusted to
1
/16" clearance between O.D. of stone/wire wheel and the
inside edge of tool rests.
• Adjust the tool rests to insure the work piece to be ground will contact the wheel slightly
above centre line of the shaft.
• Periodically check adjustment to insure proper clearance is maintained.
GRINDING STONE
•
To replace grinding wheel remove outer guard by removing 3 screws (Fig 5 A)
• Remove hex nut (Fig. 5B) using appropriate wrench.
• Remove and replace stone with a proper size stone of choice insuring that the speed rat-
ing of the stone is equal to or greater than the machine nameplate.
• Assemble as shown in Fig. 5. The nut should be tightened to a recommended 55 in/pds of
torque. Note the orientation of the flanged washers whereby the large diameter of washer
should bear against the wheel. Under no condition should the washers be reversed.
Caution: The grinding wheels must always be checked for cracks of imperfections.
This is done with the “ring test”. Tap the wheel gently near the outer rim with the handle of a
screwdriver; you should hear a clear bell-like ringing. If a dull thud occurs do not use the
wheel! This means the wheel has been damaged and will, most likely, come apart during
normal operations.
