6-2. How To Adjust Chamfering Levels
WARNING
Be sure to remove the air hose from the tool
beforehand whenever adjusting chamfering levels.
The max. chamfering capacity:
Stainless Steel .......................... 3C
Mild Steel ...................................7C
(1) Loosen the Hex. Socket Head Cap Screw ① of the
Head ④ (Fig. 5).
(2) Turn the Head ④ to match the Guide line of Head
④ with the scale of Eccentric Ring ③ (Fig. 5, Fig. 6).
●
The level guide is only for reference. If accurate
chamfering is required, set the tool at a chamfering
level about 0.5 smaller than the desired one. Try a
test cut. Then adjust the tool for accurate chamfering.
In the case of Mild Steel.
You can select chamfering levels from 0 to 7C freely.
The maximum chamfering capacity for one-cut is
4C. For 4C to 7C, chamfer a workpiece twice or
three times.
(Ex. 7C: 4C → 5.5C → 7C Total 3 times)
In the case of Stainless Steel.
You can select chamfering levels from 0 to 3C freely.
Chamfer the desired volume at a time without
dividing the chamfering jog to several times
●
If the Head ④ is in difficult position to work with
loosen the Hex. Socket Set Screw ② of Eccentric
Ring ③ to adjust the Head ④ in a proper position.
After adjustment, tighten the Hex. Socket Set Screw
② firmly to prevent becoming loose during operation
(Fig. 5).
(3) Firmly install the Head on the end of Eccentric
Ring without making any clearance and tighten the
Hex. Socket Head Cap Screw ① (Fig. 5).
