1. Always check to see that the power switch is in the off position and the safety lock is

removed anytime other than during use. If the power switch is not in the off position place

it there and remove the safety lock pin from the switch.

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.

4. 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.

. 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?

Does the stone have cracks or is it chipped?

Are any of the guards missing or damaged?

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.

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.

11. 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.

12. Connect the power cord to a properly grounded 110/120 volt outlet.

Unpacking the grinder

Carefully remove the grinder and all components from the box. This should include the grinder plus

3 guards, hardware (3 nuts, washers, and 2 plastic thumb screws) and 1 table plate.

Assembling the grinder

Be sure the on/off switch is in the off

position and the power cord is unplugged!!

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 1/4” from

the stone.

The large ‘’T” guard mounts on the stud on the right bottom of the main table using one washer

and one nut.

Assembling the grinder (cont.)

Installing the guards (cont.)

PLEASE NOTE: the large “T” guard is offset and only mounts one direction so it slides

along the angled lip in the stone opening of the main frame.

The “T” guard must be adjusted so it is no more

than 1/8” from the stone.

Installing the table plate

Mount the table plate on the left or right side of the table using the 2 washers and 2 thumb screws.

8

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.

4. 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.

. If the angle is correct continue on to the section on blade sharpening. If not proceed with

number 6.

9

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 4. Continue to adjust as

needed.

9. Once the proper angle is achieved lock the adjustment by tightening the nuts loosened in

step 6.
