Setup

Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever you see this symbol. This sprayer builds up an internal pressure of 2000 psi (138 bar, 13.8 MPa) during use. Follow this Pressure Relief Procedure whenever you stop spraying and before cleaning, checking, servicing, or transporting equipment to prevent serious injury.

1. Turn Prime Knob down to PRIME position to relieve pressure.

Cup Fill Use only water-based or oil-based (mineral spirit-type) materials with a flash point greater than 100° F (38° C).
Do not use materials which state “FLAMMABLE” on the packaging. For more information about your material, request a Safety Data Sheet (SDS) from distributor or retailer.
When spraying oil-based material, use outdoors or in a well-ventilated indoor area with a flow of fresh air.
Keep spray area well-ventilated. Keep a good supply of fresh air moving through the area.
If spraying oil-based materials, review Fluid Compatibility, page 21, and follow Static Grounding Instructions (Oil-Based Materials), page 21.

1. Insert one FlexLiner into the Cup Support.
   NOTE: Verify there is no damage to the top sealing edge of the FlexLiner, such as a crease or fold. If damaged it will leak air and lose prime.

2. Firmly tighten the Cup Lid onto the Cup Support to ensure an airtight seal.
   NOTE: To ensure an airtight seal, the gasket inside the Cup Lid is lubricated by the factory.
   If lubrication has washed away, apply Seal Lube (included) to the gasket.

3. Insert the Funnel into the Cup Lid, twist to lock. Snap the Strainer into the Funnel to strain your paint as you fill your cup.

4. The Strainer’s Air Tube will prevent paint from overfilling the cup. Fill the cup as follows:
   a. Watching the Funnel (not the cup), slowly pour paint into the Funnel.
   When the paint stops draining down, the cup is full.
   NOTE: If the paint stops draining but you see the cup is not full, use a stir stick to scrape the captured debris on the top of the Strainer until the paint resumes draining.
   b. With the Funnel and Strainer still attached to the cup, pour excess paint from the Funnel back into the paint can.
   c. Lift up the Strainer and look to verify you can see crossbars in the bottom of the Funnel. If not, the cup is overfilled. Pour excess paint back into the paint can.
   d. Remove the Funnel and Strainer from the cup and hook on edge of paint can.

Startup

1. Install the cup onto the sprayer as  follows:
   a. Verify Pump Filter is installed and clean.
   b. Align VacuValve (on Cup Lid) with Prime Knob (on sprayer).
   c. Push cup assembly onto the sprayer, twist to lock.

2. Prime the pump as follows:
   a. Verify Prime Knob is pointed down to PRIME position.
   b. Plug sprayer into a grounded power source.
   c. Open the VacuValve cap and gently squeeze the FlexLiner until no more air bubbles appear in the VacuValve.
   NOTE: Tilt the sprayer such that the VacuValve is the highest point so that all air in the FlexLiner can be fully evacuated.
   d. Continue to squeeze the FlexLiner while pulling the Trigger for 10 seconds.
   NOTE: This will purge all air from the pump and cup. Paint will not spray out, but will recirculate through the pump and back into the cup.
   e. When no more air bubbles appear in the VacuValve, release the Trigger and close the VacuValve cap.

3. Turn Prime Knob forward to SPRAY position. Verify Spray Tip is forward in the SPRAY position.

4. Point the sprayer into a waste pail and pull the Trigger for 5 seconds to spray out storage fluid.
   • To avoid pump damage, if the sprayer does not spray after 5 seconds, STOP and repeat STARTUP.

You are now ready to spray!
NOTE: For best results, to evacuate all material from the FlexLiner when the material is nearly gone, gently squeeze the bottom of the FlexLiner to push the last of the material up to the Cup Lid.
IMPORTANT! The motor has a built-in feature to protect itself from overuse. If the motor stops, the thermal switch has tripped. The motor will operate normally after cooling for 20-30 minutes.

Spraying

Use only water-based or oil-based (mineral spirit-type) materials with a flash point greater than 100° F (38° C).
Do not use materials which state  “FLAMMABLE” on the packaging. For more information about your material, request a Safety Data Sheet (SDS) from distributor or retailer.
When spraying oil-based material, use outdoors or in a well-ventilated indoor area with a flow of fresh air.
Keep spray area well-ventilated. Keep a good supply of fresh air moving through the area.

1. Set the Speed Control to lowest available setting.

2. Pointing at a piece of scrap cardboard, pull the Trigger to test the spray pattern.

3. If needed, slowly increase the Speed Control to the setting that produces a good spray pattern.
   NOTE: To minimize overspray, always spray at the lowest speed setting that gives a good spray pattern.

4. Adjust the sprayer’s distance from the surface and your hand speed to achieve the desired surface coverage.

Spray Tip Orientation

To avoid serious injury from skin injection, do not put your hand in front of the Spray Tip when installing or removing the Spray Tip and Tip Guard.

Adjust the Spray Tip Guard for the desired vertical or horizontal spraying direction.

Spray Pattern Quality
A good spray pattern is evenly distributed without voids or runs. Adjust sprayer Speed Control (if available), hand speed, and distance from the wall to get a good spray pattern.
If tails persist, material may need to be thinned. If material needs to be thinned, follow manufacturers recommendations.

Spray Angle
Use a piece of scrap cardboard to practice these basic spraying techniques before you begin spraying the surface.

• Hold sprayer 10-12 inches (25-30 cm) from surface and aim straight at surface. Tilting the sprayer to direct the spray angle causes an uneven finish.

• Flex wrist to keep sprayer pointed straight. Fanning sprayer to direct spray at angle causes uneven finish.
  NOTE: How fast you move the sprayer will affect spray application. If material is pulsating, you are moving too fast. If material drips, you are moving too slow. See Troubleshooting, page 26.

Aiming Sprayer
Aim the sprayer at the bottom edge of the previous stroke, overlapping each stroke by 50%.
Triggering Timing
Pull Trigger after starting stroke. Release Trigger before end of stroke. Sprayer must be moving when Trigger is pulled and released.

Reversible Spray Tips
Your sprayer is shipped with wide and narrow reversible Spray Tips.

With the exception of any special, extended, or limited warranty published by Graco, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of non-Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above.
