OPERATION (CONTINUED)
• Note the original bevel angle on the item to be sharpened and
try to maintain that angle. Sharpening a cutting edge requires
removing burrs from edge.
• Deburring edge is done best by using the grinder to pull burr
from edge across the bevel angle.
• The grinding wheel should rotate into object being sharpened.
• Dip work into a coolant regularly to prevent overheating.
Overheating can weaken metals.
MAINTENANCE
WARNING:
Make certain that the unit is disconnected from
power source before attempting to service or remove any
component.
CLEANING
• Keep machine and workshop clean. Do not allow sawdust to
accumulate on the tool.
• Keep wheels clean. Dirt on wheels will cause poor tracking and
belt slippage.
• Operate tool with dust collector to keep dust from
accumulating.
WARNING:
After sanding wood or non-metallic material, always
clean dust collector and guards of sawdust before grinding metal.
Sparks could ignite debris and cause a fire.
• Be certain motor is kept clean and is frequently vacuumed free
of dust.
• Use soap and water to clean painted parts, rubber parts and
plastic guards.
LUBRICATION
• The shielded ball bearings in this tool are permanently
lubricated at the factory. They require no further lubrication.
• When operation seems stiff, a light coat of paste wax applied to
the belt table and disc table will make it easier to feed the work
while finishing.
• Do not apply wax to the belt platen. Belt could pick up wax and
deposit it on wheels causing belt to slip.
KEEP TOOL IN REPAIR
• If power cord is worn, cut or damaged, have it replaced
immediately.
• Replace worn abrasives when needed.
• Replace any damaged or missing parts. Use parts list to order
parts.
• Any attempt to repair motor may create a hazard unless repair
is done by a qualified service technician.
GRINDING WHEEL MAINTENANCE
• As wheels wear, tool rests should be positioned closer to the
face of the wheels.
• The gap between the wheel and the tool rest should not be
greater than 1/16”. When the wheels are worn to the extent that
the 1/16” maximum gap cannot be maintained, the wheels
should be replaced.
• Replacement wheels should have a minimum rated speed of at
least 3600 RPM.
• Maximum wheel diameter is 8”.
• To loosen nuts holding the wheels, disconnect power and push
a wood wedge between the tool rest and the wheel to keep
the shaft from turning. The threads on the right side of the
grinder (facing unit) are right hand; threads on the left side are
left hand. Tighten nuts securely before operating the grinder.
• For grinding efficiency, wheels should be dressed periodically,
especially if they become clogged from grinding soft metals.
