Yes—you can sharpen a chainsaw chain with a Chicago Electric sharpener by setting the chain in the vise, dialing in the correct cutter angle, adjusting the chain stop and depth stop so the wheel only lightly contacts the tooth, sharpening all cutters on one side first, then reversing the angle and doing the opposite side. On the current Harbor Freight listing, the Chicago Electric sharpener family includes item 63803 and related legacy SKUs such as 68221, and the vise/table adjusts up to 35° left or right.

Short version:
Before touching the grinder, determine the correct sharpening angle from the chain or saw documentation. The Harbor Freight manual explicitly says to refer to the saw chain’s instructions for the sharpening angle. Many common chains are sharpened at 30°, but you should use your chain’s actual specification. (manuals.harborfreight.com)
Also do the basic setup first:
With the machine unplugged, place the chain in the vise so the angled cutting edges face right, engaging the chain on the chain wheels/rollers. Then squeeze the vise handle and adjust the clamp lock nut until the chain does not move when clamped. (manuals.harborfreight.com)
This step matters because any movement during grinding changes cutter geometry and makes the chain cut crooked.
For the right-hand cutters, the Harbor Freight manual says to loosen the angle adjustment knob and set the angle arrow to the correct angle to the left of 0 on the miter gauge. After that, position the first right-hand cutter and engage the chain stop. (manuals.harborfreight.com)
In practice:
This is the critical calibration step.
With the wheel lowered into position manually:
This prevents two common problems:
Now plug in the unit, switch it on, and let it reach full speed. Clamp the chain and lower the handle until the wheel contacts the cutter and sharpens it. The manual specifically says to turn the sharpener off before moving the chain. Then rotate/advance the chain to the next cutter of the same hand and repeat. Continue until all cutters on that side are sharpened. (manuals.harborfreight.com)
A practical workflow is:
Leave the chain in the vise. For the left-hand cutters, loosen the angle adjustment knob and move the angle arrow to the same angle to the right of 0 on the miter gauge. Then position the first left-hand cutter, engage the chain stop, and repeat the same sharpening sequence. (manuals.harborfreight.com)
So the pattern is:
From a chain-dynamics standpoint, equal cutter length is essential. STIHL’s service documentation states that all cutters should be equally long; if cutter lengths vary, cutter heights vary too, which can cause rough chain running and even chain damage. (ssc.stihl.com)
Best practice:
This is the step many people miss. When you sharpen cutters, the depth gauge relationship changes. STIHL’s manuals state that the depth gauge setting should be checked after each sharpening, and if the depth gauge protrudes above the file gauge, it must be reworked. They also warn that depth gauges that are too low increase kickback tendency. (ssc.stihl.com)
So after grinding the cutters:
Harbor Freight’s current product listing still shows this Chicago Electric sharpener family under item 63803, and it groups related legacy item numbers including 68221, which is likely the model family you mean. The product page says the unit has a chain vise that adjusts to chain designs/pitches, a vise/table angle of 35° left or right, and uses a 4-1/4 in. x 1/8 in. grinding wheel. (harborfreight.com)
That means the general setup procedure is still the same today for the common Chicago Electric/Harbor Freight versions:
Think of the machine as doing three separate jobs:
Angle control
The miter gauge sets the cutter’s top-plate sharpening angle. If this is wrong, the chain will cut poorly even if the edge looks shiny. (manuals.harborfreight.com)
Length control
The chain stop determines where the tooth sits under the wheel, so all teeth end up the same length. Equal length matters for straight cutting. (manuals.harborfreight.com)
Depth control
The depth adjustment prevents the wheel from grinding too far into the gullet. (manuals.harborfreight.com)
If your saw starts pulling left or right after sharpening, the usual cause is that one side’s cutters ended up longer or sharper than the other. STIHL explicitly notes that unequal cutters cause rough running; in practice they also cause side pull in the cut. (ssc.stihl.com)
From a safety standpoint, improper sharpening is not just a performance issue—it can become a kickback and injury issue. Official chain maintenance guidance warns that incorrect depth-gauge height, especially gauges that are too low, increases kickback tendency. (ssc.stihl.com)
Also follow the tool safety requirements:
Harbor Freight’s manual says to inspect the tool before use and replace the grinding wheel once it wears down to 3 inches diameter. (manuals.harborfreight.com)
If you want the setup to be exact, the next useful data points are:
With those, you can optimize:
