Your new chain saw sharpening attachment kit will fit on Dremel rotary tool models 275, 285, 395, 398, 850 and 780. When attached to a Dremel rotary tool, the Chain Saw Sharpening attachment will sharpen nearly all popular sizes of chain if you follow these simple instructions.

ASSEMBLY OF CHAIN SAW SHARPENING ATTACHMENT

Because there are different sizes and types of chains used on different saws, your new sharpener must be assembled to suit your particular chain. To do this:

1.First determine the size and pitch of your saw chain. Refer to your chain saw owner’s manual, your chain saw instruction manual or contact the chain manufacturer for this information.

2.Refer to the chart below for the correct grinding stone.

	Grinding	Grinding	Grinding
Chain	Wheel Size	Wheel	Wheel	Guide
Size / Pitch	(Diameter)	Color	Catalog No.	Gauge
1/4" PITCH	5/32"	Blue	453	Side 1

2.The saw should first be positioned so that you are looking at the side of the chain bar with the motor to your right. Cutter teeth on the far side of the chain are sharpened, from inside to outside, or away from you, as shown in Figure

5.The guide (B) should be laid flat on the tooth with the 30º index line (L) par- allel with the chain. This index line should be aligned by eye with the chain.

Two or three light strokes are usually enough unless the cutters have been damaged. Sharpen all cutters equal. Start with the cutter with the most visual damage (i.e. nicks or gouges) and sharpen all cutters back equally. Do not remove excessive material as this only shortens the life of the chain.

Note: Sharpen cutter teeth (J) only, not the depth gauge (K).

3.When all of the teeth on the top of the bar have been sharpened, advance the chain using a glove or a rag to protect your hand, by pulling the chain toward the end of the bar. Repeat until all the teeth on the far side of the chain have been sharpened.

4.Turn the saw around so that you are looking at the side of the chain bar with the motor to your left. Sharpen the cutter teeth on the far side of the chain, from inside to outside, or away from you, as shown in Figure 6. The guide should be laid flat on the tooth with the 30º index line parallel with the chain.

3.When you have determined the correct grinding stone for your chain from the chart, assemble attachment by screwing the guide (B) and appropriate number of spacers (C) to the clamp (D) using the two screws (A), as shown in figure 1.

•If using the 7/32" diameter (pink) grinding stone, assemble both spacers between the guide and the clamp.

•If using the 3/16" diameter (orange) grinding stone, assemble with only one spacer between the guide and the clamp.

•If using the 5/32" diameter (blue) grinding stone, no spacers are needed.

4. Securely mount the correct grinding stone in your tool with approximately

1/4" of the shank exposed between the chuck cap and the stone (Figure 2).

Use the rotary tool wrench to securely tighten the chuck cap.

5. Remove the housing cap from your rotary tool and screw on the chain saw

sharpening attachment (Figure 3).

6. Using the appropriate side of the gauge (E) (see above chart), check to see

the chain.

5.After your chain has been sharpened a number of times, you may find that it does not cut as fast as you feel it should. Each cutter on your chain has a depth gauge (K) just ahead of the cutting edge (J) that determines how big a bite it can take. To check for proper depth of the cut, lay a metal straight edge across the tops of the cutting edges, as shown in Figure 7, and check the dimension indicated. This dimension should be approximately equal to the thickness of the gauge furnished with your chain saw sharpening kit. If it is not, file or grind the chain depth gauge until the clearance is approximately equal to the thickness of the sharpening kit gauge. Be careful to maintain its shape. Do not remove more material than necessary or you will overload your saw. Also, be careful to keep this depth gauge setting uniform on all cutter teeth or you will not be able to make a straight cut.

if the guide (B) is properly positioned in respect to the grinding stone (F). The

gauge must be flush with the corner (G) of the guide while making contact with

the grinding stone (Figure 4).

If the guide is not properly positioned, use a screwdriver (the end of the gauge has a screwdriver (H) on it) to loosen the two guide mounting screws (A) enough so the guide can be moved (I). It has elongated holes to allow for adjustment. Using the appropriate side of the gauge, adjust the guide so it is properly positioned in respect to the grinding stone and tighten the screws.

SHARPENING THE CHAIN

1.Set your saw on a flat, solid surface so it will not slip while you are sharp- ening the chain. The chain tension should be adjusted as specified in the Chain Saw Owner’s Manual. If it is too loose, the teeth will move, resulting in a poor sharpening job.

Sharpening will be best accomplished if done on the flat of the saw bar – somewhere near the middle of the bar.
