Operation
CAUTION:
Proper handle pressure during cutting and maximum cutting efficiency can be
determined by the amount of sparks that is produced while cutting. Your pressure on
the handle should be adjusted to produce the maximum amount of sparks. Do not
force the cut by applying excessive pressure on the handle.
Hold the handle firmly. Switch on the machine and wait until the wheel attains full
speed before lowering gently into the cut. When the wheel contacts the workpiece,
gradually bear down on the handle to perform the cut. When the cut is completed,
switch off the machine and wait until the wheel has come to a complete stop before
returning the handle to the fully elevated position.
Cutting Capacity
The maximum cutting capacity of the machine depends on cutting angle and the
shape of the workpiece.

Should any of the screws be loose, retighten them immediately. Failure to do so could
result serious hazard.
Changing Cut-off Wheel
When the cut-off wheel has worn down considerably and results in reduced efficiency,
replace with a new one immediately.
Storing after Operation
Disconnect the machine after operation and store it out of reach of children.
Lubrication
To prolong the service life of this machine, lubricate the machine’s active parts such as
those of shaft threads, vise plate and holder etc. every month.
