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 symbol refers to procedure-specific risks. Refer back to these warnings. Additional, product-specific warnings may be found throughout
the body of this manual where applicable.
WARNING
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.
• 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 230V circuit and has a grounding plug similar to the plug
illustrated in the figure below.
ti11376a
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 3-blade grounding plug and a 3-slot receptacle
that accepts the plug on the product.
• Make sure your extension cord is not damaged. If an extension cord is necessary, use 15m
(49.2 ft) 1.0 mm2, 30m (98.4 ft) 1.5 mm2, or 50m (164.0 ft) 2.5 mm2 minimum to carry the
current that the product draws. An undersized cord results in a drop in line voltage and loss of

Selecting the Right Tip
Selecting the Right Tip
Tip Hole Size
•
Spray should be atomized (evenly distributed, no gaps or edges). Start at a low
pressure setting, increase pressure a little
at a time until paint atomizes.
•
Fluid flow rate is controlled by tip hole size.
•
The best tip hole size for fluid you are
spraying is determined by type of coating
and type of surface you are spraying.
•
Use large tip hole size when spraying
thicker coatings.
•
Use small tip hole size when spraying thinner coatings.
•
Tips wear and enlarge when you spray.
Starting with a tip hole size smaller than the
maximum will allow you to spray within
rated flow capacity. To prevent excessive
wear, spray at lowest pressure that atomizes paint.
NOTE: If maximum pressure of sprayer is not
enough for good spray pattern, tip is too large or
worn. See Reversible Tip Selection Table, page
16.
