こ の 取 り
１ ：
Safety precautions
It has a structure that kneads the grab by moving the resin mallet up and down.
The kneading pressure will be 250 kg(551lb)or more, and if you pinch your limbs, a serious accident will
occur. Before operating the cylinder, make sure that there is nothing other than a grab before operating it.
Also, never touch the top and bottom of the cylinder during operation.
２ ：
Precautions for safety inspection
Since high-pressure air and 100/110V power supply are used, if the air hose is found to be detached, scratched,
deteriorated due to aging, or scratched, replace it regularly.
100/110V power cord and foot switch wires can be damaged by being stepped on or pinched. If any scratches
are found, ask our company or a professional engineer to replace it.
３ ：
Precautions for replacing the molding jig
If multiple grab type jigs are prepared, the user may replace them. In this case, use a formal tool to install it
properly. Also, it is possible that the screws will loosen during work, so check regularly for loose screws
before starting work.
The jig and the screw itself have a locking bolt, so be sure to tighten this screw as well.
４ ：
Precautions for inspection
Check the following items when inspecting the machine or replacing the grab pushing jig.
a: Turn off the power switch of the control panel or unplug the power cord from the outlet.
b: Remove the air hose from the regulator on the next page ④and check that the pressure meter has become
zero.

Applications and features
The air type (grab presser)grab type machine is a device that softens the hardness of a baseball glove when
purchased, and then blends it into the hand to soften it.
The work of hitting, pushing and kneading with hand tools is reduced by the pressure of air. If you hit it with
an extremely hard object, the skin may be scratched, but since it is pressed down by the pressure of the air, the
feeling of hand fir is mechanized and it is easier.
In addition, it is possible to easily change the sideburns pressure by adjusting the air pressure.

Control panel explanation
① ：
After inserting the power switch 100 / 110V plug, turn it on and the power lamp of ②will light up.
If you operate the foot switch in this state, the cylinder will descend and pressure will be applied to the grab.
When the switches ①and ③are turned on, the cylinder can be continuously moved up and down according
to the set time of the timer.
⑤・⑥How to set the timer with the knob
：
⑤ (Small red knob)is the time when the cylinder is raised and waiting
⑥Time when the cylinder is lowered and pressurized (large green knob)
Both photos are set to about 1 second.
※If you turn on the automatic switch, the cylinder will drop immediately, so be careful not to pinch anything
other than the grab.
