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.
SELECTION OF BLADES
Accessory blades
To ensure maximum operating efficiency and results,
it is very important to select the appropriate blade
best suited to the type and thickness of the material
to be cut. Three types of blades are provided as
standard accessories. The blade number is engraved
in the vicinity of the mounting portion of each blade.
Select appropriate blades by referring to Table 1.
HOUSING THE HEXAGONAL BAR WRENCH
It is possible to house the hexagonal bar wrench on the
base. (See Fig. 16)
MAINTENANCE AND INSPECTION
1. Inspecting the blade
Continued use of a dull or damaged blade will result
in reduced cutting efficiency and may cause
overloading of the motor. Replace the blade with a
new one as soon as excessive abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do
so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the
power tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
