Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this
equipment. The exclamation point symbol alerts you to a general warning and the hazard
symbols refer to procedure-specific risks. When these symbols appear in the body of this
manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols
and warnings not covered in this section may appear throughout the body of this manual
where applicable.
GROUNDING
This product must be grounded. In the event of an electrical short circuit, grounding
reduces the risk of electric shock by providing an escape wire for the electric current.
This product is equipped with a cord having a grounding wire with an appropriate
grounding plug. The plug must be plugged into an outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
• Improper installation of the grounding plug is able to result in a risk of electric
shock.
• When repair or replacement of the cord or plug is required, do not connect the
grounding wire to either flat blade terminal.
• The wire with insulation having an outer surface that is green with or without
yellow stripes is the grounding wire.
• Check with a qualified electrician or serviceman when the grounding instructions
are not completely understood, or when in doubt as to whether the product is
properly grounded.
• Do not modify the plug provided; if it does not fit the outlet, have the proper outlet
installed by a qualified electrician.
• This product is for use on a nominal 110V or 230V circuit and has a grounding
plug similar to the plugs illustrated in the figure below.
ti24583a
• Only connect the product to an outlet having the same configuration as the plug.
• Do not use an adapter with this product.
Extension Cords:
•
Use only a 3-wire extension cord that has a grounding plug and a grounding
receptacle that accepts the plug on the product.
• Make sure your extension cord is not damaged. If an extension cord is necessary
use 12 AWG (2.5mm) minimum to carry the current that the product draws.
• An undersized cord results in a drop in line voltage and loss of power and
overheating.

Warnings
WARNING
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and material fumes, in work area can ignite or
explode. To help prevent fire and explosion:
• Do not spray flammable or combustible materials near an open flame or sources
of ignition such as cigarettes, motors, and electrical equipment.
• Material or solvent flowing through the equipment is able to result in static
electricity. Static electricity creates a risk of fire or explosion in the presence of
material or solvent fumes. All parts of the spray system, including the pump, hose
assembly, spray gun, and objects in and around the spray area shall be properly
grounded to protect against static discharge and sparks. Use Graco conductive
or grounded high-pressure airless material sprayer hoses.
• Verify that all containers and collection systems are grounded to prevent static
discharge. Do not use pail liners unless they are anti-static or conductive.
• Connect to a grounded outlet and use grounded extensions cords. Do not use
a 3-to-2 adapter.
• Do not use a material or a solvent containing halogenated hydrocarbons.
• Do not spray flammable or combustible liquids in a confined area.
• Keep spray area well-ventilated. Keep a good supply of fresh air moving through
the area.
• Sprayer generates sparks. Keep pump assembly in a well ventilated area a least
20 feet (6.1 m) from the spray area when spraying, flushing, cleaning, or
servicing. Do not spray pump assembly.
• Do not smoke in the spray area or spray where sparks or flame is present.
• Do not operate light switches, engines, or similar spark producing products in the
spray area.
• Keep area clean and free of material or solvent containers, rags, and other
flammable materials.
• Know the contents of the materials and solvents being sprayed. Read all Safety
Data Sheets (SDSs) and container labels provided with the materials and
solvents. Follow the material and solvents manufacturer’s safety instructions.
• Keep a working fire extinguisher in the work area.
ELECTRIC SHOCK HAZARD
This equipment must be grounded. Improper grounding, setup, or usage of the
system can cause electric shock.
• Turn off and disconnect power cord before servicing equipment.

Operation
The system has thermal overload
protection that will automatically shut
down the sysem if it overheats. To reduce
the risk of bodily injury due to the system
restarting unexpectedly, always turn the
ON/OFF switch to OFF.
An external air compressor may be
connected to the applicator air line fitting.
This may be useful for the application of
decorative or hard-to-spray materials.
Overpressurizing the system may cause
component rupture and result in serious
injury. To reduce risk of overpressurizing
system:
• Do not use a compressor with an
output pressure greater than 125 psi
(0.86 MPa, 8.6 bar).
The system comes with the following hoses:
T-Max 506:
• Fluid Hose: 5 m of 25 mm ID & 3 m
of 19 mm ID
T-Max 657:
• Fluid Hose: 10 m of 25 mm ID & 3 m
of 19 mm ID
T-Max 6912:
• Fluid Hose: 5m, 10m, 15m, 30m of
25mm ID & 3m of 19mm ID
• Air Hose: If applicable, 18m or 33m
Hose Usage
Always attach 25 mm ID hose to pump outlet.
Other hoses may then be added up to the
maximum fluid hose lengths:
• Use shortest fluid hose length required
for the spray application (25 mm x 5 m)
minimum.
• Unnecessary hose length decreases
sprayer performance.
• Maximum fluid hose lengths:
T-Max 506:
• 15 m of 25 mm ID or 10 m of 25 mm
ID + 3 m of 19 mm ID
T-Max 657:
• 30 m of 25 mm ID or 25 m of 25 mm
ID + 3 m of 19 mm ID
NOTE:
T-Max 6912:
• 30 m of 25 mm ID + 3m of 19mm ID
NOTE: Use only one 3 m of 19 mm ID. Do not
exceed 1000 psi. Temperature usage range

IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY
