Selection Of Blades; Housing The Hexagonal Bar Wrench - Hitachi CJ 120V Handling Instructions Manual

English
When cutting stainless steel plates, adjust the unit as
described below:
1. Adjust the speed
Blade Thickness of material
No. 97 1.5 ~ 2.5 mm
NOTE:
Dial scale reading is for reference only. The higher
the speed is, the quicker the material is cut. But
the service life of the blade will be reduced in this
case. When the speed is too low, cutting will take
longer, although the service life will be prolonged.
Make adjustments as desired.
2. Set the orbital position to "0"
NOTE:
When cutting use cutting fluid (oil base cutting
fluid) to prolong the blade's service life.

in the vicinity of the mounting portion of each
blade. Select appropriate blades by referring to
Table 1.
