situation which, if not avoided, will result
in death or serious injury.
WARNING Indicates a potentially hazardous situation
which, if not avoided, could result in death
or serious injury.
CAUTION Indicates a potentially hazardous situation
which, if not avoided, may result in minor
or moderate injury or property damage.
NOTICE Indicates information or a company
policy that relates directly or indirectly to
the safety of personnel or protection of
property.
GENERAL SAFETY PRECAUTIONS
DANGER
Intake air can contain carbon monoxide or other contaminants.
Will cause serious injury or death. Gardner Denver air
compressors are not designed, intended or approved for
breathing air. Compressed air should not be used for breathing
air applications unless treated in accordance with all applicable
codes and regulations.
WARNING
Moving parts. Can cause serious injury. Do not operate with
guards removed.
Hot surfaces. Can cause serious injury. Do not touch. Allow to
cool before servicing. Do not touch hot compressor or tubing.
High pressure air. Bypassing, modifying or removing safety/relief
valves can cause serious injury or death. Do not bypass, modify
or remove safety/relief valves. Do not direct air stream at body.
CAUTION
A caution risk of bursting. Use only suitable air handling parts
acceptable for pressure of not less than the maximum allowable
working pressure of the machine.
SAFETY
GENERAL INFORMATION
Your air compressor is suitable for the Transport Market used to assist with
liquid bulk tanker ooad. The following accessories may be required:
• Relief valve
• Check valve
• Hot pressure hose
• 3-way ball valve
• Pressure gauge.

HYD-7-610 EN-5
EN
RECEIPT & INSPECTION
Ensure adequate lifting equipment is available for unloading and moving
the compressor to the installation site.
NOTICE
Lifting equipment must be properly rated for the weight of the
unit.
Lift the unit by the shipping skid only. Use straps to prevent
tipping.
CAUTION
Do not work on or walk under the compressor while it is
suspended.
Before signing the delivery receipt, inspect for damage and missing parts.
If damage or missing parts are apparent, make the appropriate notation on
the delivery receipt, then sign the receipt. Immediately contact the carrier
for an inspection. All material must be held in the receiving location for
the carrier’s inspection. Delivery receipts that have been signed without a
notation of damage or missing parts are considered to be delivered “clear.’
Subsequent claims are then considered to be concealed damage claims.
Settle damage claims directly with the transportation company.
If you discover damage after receiving the unit (concealed damage), the
carrier must be notied within 15 days of receipt and an inspection must
be requested by telephone with conrmation in writing. On concealed
damage claims, the burden of establishing that the unit was damaged in
transit reverts back to the claimant.
Read the unit specication label to verify that it is the model ordered.

INSTALLATION
SELECTING A LOCATION
GENERAL
Select a clean, dry, and bright indoor area with suciant space for proper
accessibility and cooling air ow. Install the unit at least 12 inches
(30 cm) away from walls and make sure that the main power supply is
clearly Identied and accessible.
TEMPERATURE
Ideal operating temperatures are between 32°F and 100°F (0°C and 37.8°c)
If temperatures consistently drop below 32°F (0°C). You must protect safety
relief valves from freezing.
CAUTION
Never operate in temperatures below 20°F (-6.6°C) or above
125°F (51.0°C).
HUMID AREAS
In frequently humid areas, moisture may form in the bare pump and
produce sludge in the lubricant, causing running parts to wear out
prematurely. Excessive moisture is especially likely to occur if the unit is
located in an unheated area that is subject to large temperature changes.
Two signs of excessive humidity are external condensation on the pump
when it cools down and a“milky” appearance in petroleum compressor
lubricant. You may be able to prevent moisture from forming in the bare
pump by increasing ventilation, operating for longer intervals or installing
an external crankcase heater kit.
NOISE CONSIDERATIONS
Consult local ocials for information regarding acceptable noise levels in
your area. To reduce excessive noise, use vibration isolator pads or intake
silencers, relocate the unit or construct total enclosures or bae walls.
PERMANENT MOUNTING
WARNING
Remove the unit from the skid before mounting.
The unit must be permanently mounted. When mounting the unit, bolt the
feet to a rm, level foundation.
TYPICAL DISCHARGE CIRCUIT
Discharge piping should include a relief valve to protect the compressor,
a check valve to prevent backow, and a three way ball valve to allow air
ow to downstream or vent. We also recommend to have a pressure guage
on the supply side of the ball valve to allow operator to monitor pressure.
See basic diagram below.
INSTALLING REMOTE AIR INLET PIPING
CAUTION
Do not operate the unit without air inlet lter(s).
If the air around the unit is relatively free of dirt, install the air inlet lter(s)
at the inlet connection at the bare pump. If remote air inlet piping or heavy
duty ltration is required, contact your dealer for information.
INSTALLING DISCHARGE PIPING
When you install air discharge piping, adhere to the following general
guidelines. Contact your dealer for more information.
WARNING
Do not use plastic pipe, rubber hose, or lead-tin soldered joints
anywhere in the compressed air system.
WARNING
If an aercooler, check valve, block valve, or any other restriction
is added to the compressor discharge, install a properly-sized
ASME approved safety/relief valve between the compressor
discharge and the restriction.
CAUTION
If you will be using Gardner Denver synthetic compressor
lubricant, all downstream piping material and system
components must be compatible. Refer to the following material
compatibility list. If there are incompatible materials present
in your system, or if there are materials not included in the list,
contact Gardner Denver for recommendations.

unit’s discharge pressure and temperature. DO NOT USE PVC PLASTIC. Use
pipe thread sealant on all threads, and make up joints tightly to prevent air
leaks.
DRIVE OPTIONS
• DIRECT DRIVE
A 1100 series ange is available to direct drive the GD 70. The following
guidelines should be followed:
• Compressor shaft and PTO shaft should be parallel within 2 degrees.
• Maximum compound drive angle must be no greater than 11 degrees.
• Install a “U” bolt hanger for safety in case of a driveshaft failure.
• HYDRUALIC DRIVE
If the unit is to be driven by hydraulic motor, the shafts must be aligned as
follows:
• Shaft oset of no more than 0.015”.
• Shafts parallel within 1 degree.
COMPRESSOR LUBRICATION
CAUTION
Do not operate without lubricant or with inadequate lubricant.
Gardner Denver is not responsible for compressor failure caused
by inadequate lubrication.
SYNTHETIC COMPRESSOR LUBRICANT
We recommend AEON AC-SY compressor lubricant from start-up. See the
WARRANTY section for extended warranty information.
ALTERNATE LUBRICANTS
You may use AEON AC-HC or a comparable petroleum-based lubricant that
is premium quality, does not contain detergents, contains only anti-rust,
anti-oxidation, and anti-foam agents as additives, has a ashpoint of 440°F
(227°C) or higher, and has an auto-ignition point of 650°F (343°C) or higher.
See the petroleum lubricant viscosity table below. The table is intended
as a general guide only. Heavy duty operating conditions require heavier
viscosities. Refer specic operating conditions to Gardner Denver for
recommendations.

If you use a petroleum-based compressor lubricant at start-up and decide
to convert to Gardner Denver synthetic compressor lubricant later on, the
compressor valves must be thoroughly decarbonized and the crankcase
must be ushed before conversion.
FILLING PROCEDURES:
1. Unscrew and remove the oil ll plug (A).
2. Slowly ll the crankcase with lubricant until thelubricant reaches
the top thread of the oil ll opening and the top of the sight
glass. Crankcase capacity for the GD 70 is one (1) liter.
3. Replace the oil ll plug HAND TIGHT ONLY.

OPERATION
GENERAL
Your air compressor was designed for 100% continuous duty operation
with the use of Gardner Denver svnthetic compressor lubricant and 60%
continuous duty operation with the use of petroleum lubricant. In other
words synthetic lubricant allows the compressor to pump continuously
without cycling. Petroleum lubricant limits the compressor to a maximum
of 36 minutes of pumping time per hour. The compressor should not be
cycled more than 10 times per hour.
