Description

IMPORTANT NOTICE

Please read these instructions BEFORE operating the machine. There are a few steps that need to be taken before connecting the machine to any power source. This machine requires clean, dry, and oil-free air. We recommend using an oil-free compressor. If your compressor is an oil type, you MUST have an oil removal filter (coalescing type) installed in the air supply line to this pneumatic hand engraver.

QUICK SET UP INTRODUCTION

AIR SUPPLY REQUIREMENTS

The engraving machine requires 1.4 CFM(40 liters/min.) at a minimum of 45 psi(3.1 bar). Maximum input is 125psi(8.6 bar). We encourage reducing the air pressure from a regulator to 45~60psi (3.1~4.1 bar) as this ensures a stable air pressure supply. The compressed air must be clean, dry, and oil free. The filter supplied with each unit is a final filter and is not capable of removing large amounts of water, oil, or contaminants.

If the air supply has excessive water, oil, or contaminants, an additional filter/water trap and coalescing oil removal filter must be installed ahead of the unit. Oil or water contamination will damage the engraving machine.

INITIAL SETUP

Decide where you want to place the machine on your bench and where you would like the air filter located. Make its location readily accessible so it is easy to drain water from the bowl daily. You may attach the air filter to your machine, workbench, or wherever you desire.

Here we show it attached to the back right side of the machine. Remove the screw at this location and place the screw through the key hole opening in the filter bracket. Tighten the screw to secure the bracket. The bottom screw in the bracket will position into the slot to keep the filter from twisting/ pic.3 )

If push-to-connect fittings are new to you, they are amazing with the air pressure TURNED OFF, simply insert the hose all the way into the fitting opening - it stays attached. To disconnect, press in on the white ring while gently pulling the hose out. (pic.2, pic.3)

CONNECT HANDPIECE

There are two fittings to attach impact handpieces. Decide which handpieces you want in positions 1 and 2. Connect the handpiece hose to the push-to-connect fitting simply by pushing the hose inside the white ring receiver. A selector knob above the connections lets you select which impact handpiece you want to use, 1 or 2.

NOTE: Make sure the selector knob is turned until it stops, either direction.

An Auxiliary outlet is a straight flow air supply that is limited to 40psi(2.7 bar). The knob is a twist-open/twist-close valve. (pic.l) This is where you connect a Rotary Handpiece or other pneumatic tools.

OPERATING INSTRUCTION

HOW TO TUNE YOUR PNEUMATIC HAND ENGRAVING MACHINE

Properly tuning your engraving machine by adjusting the strokes per minute and air pressure is crucial for achieving optimum performance. Follow these steps to tune your machine:

Turn on your air compressor and wait for it to cycle off and stop running after filling the tank.

Turn on the engraving machine and set the stroke per minute dial at 2300. Use the pressure control knob on the front of the machine to back the air pressure down to 2 to 5 psi (0.1 to 0.4 bar).

Hold the handpiece you have selected to use with the tool holder next to your ear in a vertical position.

Slowly increase the air pressure without depressing the foot throttle until the handpiece vibrates, and more air pressure will make it knock. Slowly add air pressure and when the knocking barely stops, this is considered the perfect air pressure operating range for that particular handpiece.

HOW TO USE THE FOOT PEDAL

The engraving machine foot pedal is operated like an automobile accelerator and not like a flexible-shaft foot control. Follow these steps to use the foot pedal:

Begin by placing your foot on the top plate with your heel even with the bottom of the top plate.

Position the tool before depressing the foot pedal. Never depress the foot pedal and then try to bring a stroking handpiece to the work.

To increase the handpiece power, push more on the foot pedal when cutting deeper.

Coordinate your foot action with the need for more power as you work. Smoothly increase power at the start of the cut. If you need more power, press more with your foot. Gradually reduce the foot pressure as your hand tilts the graver up and out when the cut tapers to the end.

With a little practice, this hand/foot coordination will become as natural as driving a car.

HOW TO USE THE BIAS CONTROL

After you tune the handpiece, notice that the handpiece starts working as you press down on the foot pedal. Add one or two pounds of air pressure control knob. Now, open the bias control by turning it counterclockwise and notice that it does not take as much pressure on the foot pedal to activate the handpiece.

The bias control allows you to adjust the foot pedal action so you can predict the moment the handpiece will start, giving you optimum handpiece control. This is a feature that one would use for fine detail work such as bulino or shading. By opening the bias control fully, you will find that the handpiece will start to work without pressing on the foot pedal. You may find this function useful for some operations such as stippling.

EQUIPMENT MAINTENANCE

1 KEEPING THE HANDPIECE CLEAN

The impact handpiece must be kept clean for proper operation. If the operation becomes sluggish, erratic, or fails, cleaning is needed. Remove the piston and spring from the handpiece.

Take each, one at a time, and place them on a sheet of writing or copier paper. Do not use a paper towel, tissue, or newsprint. Holding it between your fingers buff and polish off any dirt or residue.

Folding the paper, use the edge to clean between the piston grooves and the space between the spring, lb clean the handpiece inside, take the writing or copier paper, and twist it to a point. Insert the paper point into the handpiece and rotate the paper and handpiece against each other This will buff and polish the inside and clean it.

IMPORTANT NOTE: DO NOT LUBRICATE THE PISTON, SPRING, OR BORE.

2 FOOT PEDAL

The pedal should require little maintenance, It should be cleaned periodically. OILING: Periodically, place a drop of oil on the throttle hinges. Keep the floor clean. When you sweep or vacuum, place the foot pedal on your bench or chair.

3 AIR SYSTEM Pneumatic Graver for Jewelry Making

If large amounts of water and contaminants are in the air supply to the unit, more frequent attention must be given to the unit filter The bowl must be drained frequently to prevent water from entering the rotary valve, and hoses. handpiece, etc. In addition, the filter element must be cleaned and/or replaced frequently. If moisture is noted in the handpiece or throttle hoses, shut the unit down immediately and drain the filter bowl. Then proceed as follows:

. Disassemble and clean impact handpiece(s) and reassemble.

. Reduce pressure setting to 10 psi and turn the unit ON to purge moisture from valves, hoses, etc.

. Located on the lower back of the machine is the drain plug to the internal air reservoir. Using a hex wrench, remove the plug and drain any moisture from the reservoir. Replace the drain plug. Before using the machine again, figure out where the moisture came from and fix the problem. It may require an additional filter(s) or water trap in the line.
