1. Always check to see that the power switch stop lever has been pushed anytime other
than during use.

2. Always place the grinder on a flat and level working surface making sure that it is properly
supported.
3. Always check the working area to be sure that it is free from all flammables such as shop rags,
gas cans, and other solvents. Frequently clean all grinding dust accumulations also.
. Always check the area around the grinder to ensure that the grindings will not be directed at
anyone or toward anything else that may be harmed.
5. Always make sure the area is free of any loose objects that could be caught in the grinding
wheel.
6. Carefully inspect all aspects of the grinder.
Are there breaks in the insulation or exposed wires on the power cord?
Has the ground terminal on the cord been broken or damaged?
Are any of the guards missing or damaged?
Does the stone have cracks or is it chipped?
Are the paper blotters missing on one or both sides of the stone?
Is the stone rated for less than the maximum spindle speed of the grinder?
Is there unusual vibration that might indicate loose, cracked or otherwise damaged stone?
7. Never operate the grinder if any of the questions in #6 can be answered yes. If the answer to
any of the items in #6 was yes unplug the unit and remove the lock from the power switch.
Have the unit repaired or replaced before any further use .If replacing the stone test it for
structural integrity for approximately 1 minute at full RPM with no grinding. Be sure to keep all
bystanders clear of the area.
8. Always check the tongue guards for clearance. Those on the guard over the top of the wheel
should be no more than ¼” from the stone. The guard at the bottom connected to the work
table should be no more than 1/8” from the stone.

9. Never use the grinder if the clearances listed in #8 above are not correctly adjusted to these
tolerances. Never adjust the guards without first checking to see that the power switch is in the
off position and the lock is removed. Adjust the guards by first loosening the nuts holding the
guards in place. Next slide the guard toward the stone to within the proper dimension. If you
are unsure of this distance do not use the grinder. If the correct distance cannot be achieved due
to stone wear do not use the grinder until the stone has been replaced. After you have
confirmed that the tongue guards are properly adjusted you may continue.
10. Always be sure that you have proper eye protection. A pair of safety glasses or a safety shield
with the safety rating of Z87 must be worn at all times while grinding. ( ANSI Z87.1-2003 )
11. Always wear gloves and be cautious of sharp edges.
12. Never operate grinder while wearing loose clothing. Always make sure that long hair is
pulled back so that it cannot be caught in grinding wheel.
13. Connect the power cord to a properly grounded 110/120 volt outlet.

Installing the guards
The 2 small guards install on the studs on the bottom of the stone guard on each side using one nut and
one washer per stud. The guards should be adjusted at all times so they are no more than 1/ ” from
the stone.

Adjusting the grinding angle
In order to provide a proper grind the angle of the grinding wheel to the work rest may need to be
adjusted. Adjust the angle to the original angle of the blade as provided by the OEM. This is
usually 30 degrees.
1. Unplug the grinder and remove the switch safety lock while checking and adjusting the angle.
2. Place the blade to be ground on the table plate so that the bottom, or the grass side of the
blade, is flat against the table plate.
3. Position the blade so that the cutting edge is against the grinding stone.
. Visually check to see if the grinding angle is correct. If the angle is correct the stone will
appear to be touching the grinding edge from the top to the bottom of the edge. If it is not
touching from top to bottom the angle needs to be adjusted.
5. If the angle is correct continue on to the section on blade sharpening. If not proceed with
number 6.

Adjusting the grinding angle (cont.)
6. Adjust the grinding angle by first loosening the nuts that lock the adjustment in place.
7. Turn the adjuster on top of the grinder to either raise or lower the grinding wheel creating the
correct angle.
8. Turn the adjuster a little at a time and check the results as in step . Continue to adjust as
needed.
9. Once the proper angle is achieved lock the adjustment by tightening the nuts loosened in
step 6.
