INSTALLATION
1. Begin by installing the
Coalescing Filter (Fig. A–6).
Remove the 2 Lock Nuts
(Fig. A–4) that hold the
U-bolt (Fig. A–7) on the
bracket.
2. Wrap the U-bolt (Fig.
A–7) around the Standing
T-Fitting (Fig. A–2) that rises
out of the air tank. Slide the
Coalescing Filter bracket
onto the threads. Use your
fingers to tighten the nuts
evenly first, then use a 7/16”
wrench to tighten.
NOTE: For most secure fit, place back of bracket
against a flat side of the Standing T-Fitting.
3. Install the Silentair
Regulator Air Filter (Fig.
A–1) by threading it onto
the pipe nut located on
the T-Fitting. Do not over
tighten!
4. Install the Air Pressure
Gauge (Fig. A–3) by simply
threading the gauge into the
fitting below the Air Filter
(Fig. A–1) as shown.
5. Install the Silentair
Reservoir Bottle (Fig. A–9)
by pushing the bowl drain
hose into the hole in the cap
of the bottle.
NOTE: Located on the
side of the compressor top
cover is a red protector
cap covering the air intake
opening, red warning label
and zip-lock bag. Unthread
the red protector cap and
remove the tag and bag.

6. Open the bottle of Silentair Synthetic Oil. Using
the Applicator Spout, carefully add the oil through
the Air Intake opening. As an alternative, you can
add the oil through the plug at the top of the head
marked OIL by unthreading the knob.
7. Check the oil level on the sight glass located by
the T-Fitting. The oil should be at the halfway mark.
NOTE: For best operation, change and refill the oil
with fresh Silentair Synthetic Oil after the first 150
hours of compressor use. USING ANY OTHER OIL VOIDS
THE 1-YEAR MANUFACTURER’S WARRANTY and will cause
increased wear and excessive oil blow-by.
8. Install the Air Intake Filter by threading it into the
Air Intake opening.
9. Two sets of tubing are included:
1. Buffer Air Tubing A (Fig. A–8)
• Extra length replacement tubing for around
the compressor pump head.
• Allows air from the compressor to cool,
depositing oil droplets in the tubing before
going to the Coalescing Filter.
• Replace when Coalescing Filter is replaced,
or if tubing becomes contaminated with oil.
2. Tubing B (Connects to Fig. A–5)
• 50 ft. (30.5m) long.
Use entire length. Coil excess.
• Connects compressor to engraving system.
10. To connect Tubing B:
• Connect the end without a compression
fitting to Tube B Connector (Fig. A–5).
• Gently snug the nut using a wrench.
• Connect the other end to engraving system.
NOTE: To connect a GraverMax SC or GraverMach,
remove the tube fitting. Install the tube directly into
the Quick Disconnect.
11. Follow the Installation Instructions on the
following page to install the Auxiliary Cooling Fan.

OPENING

OIL
AIR INTAKE
OPENING
• OPTIMAL OPERATING PSI • This compressor has
been adjusted to provide a maximum of 80 psi (plus
or minus 10 psi). By operating at this conservative
80 psi pressure, the compressor stays cooler. The
air pressure is ample for operating air tools such
as a GraverMach, GraverMax SC, System 3, rotary
handpieces, and other similar air tools.
• DRAINING WATER • Water
is generated as a by-product of
compressing air. The small T-Fitting
with the spout is for draining the air
tank. The valve has an extension
that goes to the tank bottom to
allow complete system draining.
It is not necessary to remove the
bottom tank plug or tip the compressor on its side to
drain water. Drain regularly as needed.
• SHIPPING • If shipping is required, remove
ALL OIL to prevent oil leakage and damaging oil
contamination of the air components. Do not assume
the shipper will keep the box upright during transit.
• USING THE RIGHT OIL • This air compressor is
designed to be remarkably quiet and long-lasting.
To accomplish this, it requires special oil inside the
compressor housing. The right oil to use – Silentair
Synthetic Oil (#022-163) – is included with the
compressor. Call GRS to order additional bottles.
• CHANGING OIL • When changing the compressor
oil, warm a cold machine up by running it for several
minutes and then unplug the electric cord. Drain the
tank of water. Remove the Air Intake Filter located in
the compressor head. Tip the compressor over on its
side to drain the used oil from the pump housing into
a suitable container. Properly dispose of used oil.
Stand machine back up on a level surface and refill
to the correct level with fresh Silentair Oil.
For help with this product or to order additional
supplies, please call GRS at 1-800-835-3519 or
620-343-1084 (Monday – Friday, 8 am – 5 pm).
Always add oil before use.
