RAZUR SHARP II
®
- Sharpening for the First time
11) Grinding
INTO
the tooth will NOT splinter the chrome allowing the tooth to stay sharper
longer. The chrome is the hardest part of the tooth, if it is
splintered, it will not hold an edge very long. Which is the
reason why Silvey
®
chisel & round grinders have two (2)
direction motors.
12) Begin sharpening the first tooth, ALWAYS grinding into
the tooth. Grind a little at a time, to be sure you don't burn the
tooth.
Remember
Brown discoloration = Tooth too hot
Blue discoloration = Tooth way too HOT!
If the chain is really "Rocked", do not try to take it all off at one time. Go around the chain as
many times as needed to take off the discoloration, taking a little of each time. If the working
edge of the stone is dark and the teeth are heating up, the stone may need to be dressed to
expose sharper abrasive material.
13) Make final adjustments using the cutter stop and depth screw. Slide the chain away from
the stone and check to be sure the corners line up and all of the dull material is removed. All
of the material must be removed for the chain to be properly sharpened.
14) Once the first tooth is sharpened to your satisfaction, proceed to the next cutter tooth
that is on the same side of the chain. Continue to sharpen every other tooth in sequence until
all the cutting teeth on that side are sharpened.
15) Remove the chain from the chain holder and put it in the holder on the other side.
Start the steps over starting with Step 6. When one tooth is ground on that side has been
ground check to be sure that the sharpened cutter on this side is equal in length with the
sharpened cutters on the other side.
16) Although both teeth are sharp, if both teeth are NOT of equal length,
the chain will not cut straight. To perform at its best a chain needs to have
all of its teeth the same length. When you are satisfied with this tooth,
proceed to the next cutter on the same side. Continue until all teeth on that
side are sharpened.
17) All of the cutter teeth should be sharp now.
You may want to remove the gullet material and check
the rider depth gauges before installing this chain back
onto your saw. This is also a good time to look the
chain over for any cracks, breaks, bends or unusual
wear. The cutter pictured needs to have its gullet removed and it's riders checked.
