MAINTENANCE

MAINTENANCE PROCEDURES

NOTE: Always remove the battery pack from the unit before

attempting a service operation.

Avoid using solvents when cleaning plastic parts. Most

plastics are susceptible to damage from various types of

commercial solvents and may be damaged by their use. Use

clean cloths to remove dirt, dust, oil, grease, etc.

WARNING:

Do not at any time let brake fluids, gasoline, penetrating

oils, etc., come in contact with plastic parts. Chemicals

can damage, weaken, or destroy plastic which could

result in serious personal injury.

CLEANING THE SPRAYER FOR STORAGE

See Figure 9, page 14.

When you’ve finished your project and are ready to store the

sprayer, a thorough cleaning and lubrication is recommended.

Remove battery pack from sprayer.

Remove paint container.

 Return any unused paint or stain to its original container.

 Fill the paint container with lukewarm water (for water

based paints) or non-flammable solvent (for oil-based

paints or varnish), or any other non-flammable paint

thinner (following the use of oil-based products).

NOTE: For best results, clean the container first.

 Reinstall paint container.

 Install battery pack in sprayer.

 Spray the solution onto a piece of cardboard or other

scrap material. Continue spraying until all the solution is

used.

Remove the battery pack from the sprayer.

Remove paint container.

Remove suction tube and filter.

 Remove the installed spray tip by loosening the metal

collar and turning the tip guard counter-clockwise.

 Remove the atomizer valve assembly and tip saddle. If

the tip saddle is difficult to remove, you may use the end

of the spray tip to push it out.

 Remove locking nut by turning it counterclockwise.

 Slide the pump housing assembly/container lid off

sprayer.

Pull the piston and spring off pump housing.

Using the cleaning brush (provided) and solution (deter-

mined by the last type of paint or stain sprayed), clean

all of the above parts thoroughly.

NOTE: Make sure to scrub thoroughly inside pump

housing opening so that no paint or stain material is left

behind.

Clean the vent hole in pump housing using a straightened

paper clip or toothpick.

To reassemble:

Place a line of lubricant on the piston.

NOTE: Once the provided lubricant has been used,

vegetable oil may be substituted.

Slide spring back onto piston.

Insert piston and spring assembly inside back of pump

housing.

Replace pump housing assembly/container lid into the

sprayer.

Replace the locking nut on the sprayer housing by push-

ing in while rotating clockwise to secure.

Insert the atomizer valve assembly and tip saddle into

the pump housing front opening.

NOTE: The atomizer valve assembly can be used to guide

the tip saddle into the tip guard.

Replace the spray tip and rotate tip guard clockwise to

secure.

Reinstall the suction tube and filter.

Reinstall the paint container.

The sprayer is now ready to be stored.

REPLACING ATOMIZER VALVE ASSEMBLY

See Figures 9 - 10 , page 14.

The atomizer valve causes the paint or stain material to spin

as it comes out of the sprayer. After 7 to 10 gallons of paint

or stain, the atomizer valve may no longer produce a good

spray pattern and may need to be replaced.

To replace:

Remove the battery pack from the sprayer.

 Rotate the tip guard counterclockwise and remove.

 Remove the atomizer valve assembly and discard.

NOTE: Do not discard the tip saddle

Install the new atomizer valve assembly.

NOTE: If the tip saddle is not installed, the paint sprayer

will not work.

Replace the spray tip and tip guard and rotate clockwise

to secure.

BATTERY PACK REMOVAL AND PREPARATION

FOR RECYCLING

WARNING:

Upon removal, cover the battery pack’s terminals with

heavy-duty adhesive tape. Do not attempt to destroy

or disassemble battery pack or remove any of its

components. Lithium-ion and nickel-cadmium batteries

must be recycled or disposed of properly. Also, never

touch both terminals with metal objects and/or body

parts as short circuit may result. Keep away from children.
