4.Operation procedure:
Caution Read instruction manual before operating the machine.
(1) Check thepowersource
Push the start button to judge the motor and spindle shaft is in normal conditionor not.
(2) Speed adjustment
After turn on the power, rotate the speed control switch form min. to max. position. When
rotation the switch, the speed will be changed and the speed value will be displayed in liquid
digital meter. (forelectronic LCD typeonly)
(3) Adjust work tableposition
Firstly, loose the clamp handle in left hand, then swing the table handle to properly position.
Finally tight the clamp handle.
(4) Adjust theheight of work tableto properly position,then fix the screw.
The worktable height depends on the working piece volume and height, if a incline angle is
necessary, loss the set screw first, then rotate the angle alignment the scale of the work table.
Finally, tight the set screw, if a vise will be used in the operation same as above, loose the set
screw, turn 180 degrees, let vise on theupside. Finally tight theset screw
(5) There are twoT grooves on the worktable. It is used to fix the workingpiece.
(6) There are two grooves in the base,too. It is convenientfor fixed the longer,heavier and larger
workingpiece.
(7) Secure the working piece on the worktable, as possible locatethe working piecein the center
ofthe worktable.
(8) Complete abovecautionitem and make sure no problem, then select theproperly toolfor
operation. Refer instruction manual suggestion adopt corrected cutting feed.
(9) Use Spindle Pulley to choose High or Low speed if 2-spped motor is equipped
to the machine.
(10) Before operation, the protected safety guard shall be pushed to proper position. Thereis a
micro switch in guard, the powerwill be shut down, when guard doesnot close well or not
in specified position.
