Maximum Character Chart
The Model 136A can easily exert a 3-ton force. The following chart depicts the
maximum number of characters the Model 136A is capable of stamping during
each impression, based on character size and type of material. The chart is
conservative, so the recommendations can be exceeded in many cases.
Variations in the hardness of a material will affect stamping results.

Note: The above chart is based upon the maximum number of characters for a
legible impression (.002”-.003” depth), and the Model 136A using 80 psi.
Function of Controls
1. AIR LEVEL VALVE (136A-174) - The air lever valve is located on the left side
of the press. By depressing the valve the ram head lowers.
CAUTION: When
experimenting with the handle, KEEP HANDS CLEAR OF TABLE.
MAKE
SURE THERE IS PROPER CLEARANCE BETWEEN THE TABLE TOP AND
MARKING DEVICE. Depressing the handle will cause the ram head to lower.
The lever should be held down until the ram head stops in the down position.
The lever is spring loaded to the up position. Once released the ram head will
return to the up position.
2. VALVE MUFFLERS (136A-220) - The mufflers, located on the front side of
the air lever valve, control the speed of the up and down stroke. The top
muffler controls the speed of the upstroke, while the bottom muffler controls
the speed of the down stroke. To adjust the muffler, loosen the brass jam nut
on the adjustment screw. Turning the adjustment screw inward will reduce the
flow of exhaust air, slowing the movement of the ram head. Tighten the brass
jam nut after adjustment.
