Setup
1. Position the sprayer on a level surface. Check the
oil level in the sight glass (K). If needed, fill until the
oil level is near the halfway point of the sight glass.
The oil capacity is approximately 1.0–1.2 quarts
(0.9–1.1 liters). Do not overfill.

2. Use the included spanner wrench to make sure the
packing nut (D) is just tight. Fill 1/3 full with Throat
Seal Liquid (TSL
™
). Refill as needed.
3. Determine your supply option. See
on page 11.
4. Attach electrically conductive airless hoses (V),
4-gun manifolds, and guns. See
on page 12.
5. Make sure the pressure setting is at the lowest
level. Pull the pressure adjustment knob (H) out and
turn counterclockwise until it stops, then push the
knob in to lock.
6. Turn the power switch (E) OFF. Plug the power cord
into a grounded outlet.
Flush Before Using the Sprayer
Your sprayer's pump has been factory-tested with
lightweight oil. A small amount of this oil is left in the
pump to protect parts. To avoid contaminating your
disinfectant with oil, flush the sprayer with warm soapy
water before using it for the first time.
To avoid tipping over, make sure the cart is on a flat
and level surface. Failure to do so could result in
injury, such as crushing.
Only use Graco oil (part number 16W645) in this
sprayer. Any other oil may not lubricate properly and
can cause damage to the drive train.
Your sprayer comes with a
factory-installed outlet check
valve (J). Do not attach the
airless hoses (V) directly to
the pump, as this can cause
air bubbles to form in the
disinfectant. The outlet check
valve prevents air bubbles
from forming, which can
cause damage to the
sprayer.
