OPERATION
The PH-28HD Power Hammer is a multi-stroke reciprocating machine.
The upper slide ram (hammer) is connected to the crank toggle mechanism via a multi stack leaf
spring. As the crank turns, speed and momentum load the spring which in turn “throws” the
upper slide ram down with spring force and gravity. The amount of throw and force are
controlled by speed and/or stroke.
The speed is controlled through a variable foot control and a limiting potentiometer on the upper
control box.
The foot control fully depressed will max out at whatever the limiting potentiometer is set to.
Using a power hammer is a highly artistic operation. It requires time and experience to become
proficient at creating the desired results. The best recommendation is to practice, take notes,
experiment, and seek out advice through technical colleges, individual mentoring with an
experienced operator, and through online forums and trade magazines. Practice!
Setup and Adjustments
1. Turn the main disconnect “off”.
2. Rotate the stroke handwheel to raise the upper
slide ram (hammer) to the high point of the stroke.
CAUTION:
Always wear proper hearing and eye protection with side
shields, safety footwear, and leather gloves to protect from burrs and sharp edges.
Keep hands and fingers clear of the hammer dies.
When handling large heavy sheets make sure they are properly supported.
WARNING:
HEARING PROTECTION MUST BE WORN ALWAYS WHEN
OPERATING THIS MACHINE.
