SERVICE AND MAINTENANCE
Visit www.hdhudson.com/FAQS
Clean and dry your sprayer after every use to greatly
prolong its useful service life. Many spray materials
will harden if left in the sprayer and plug up the
nozzle, shut-off valve or supply tube. The soft parts,
O-rings and gaskets, will ultimately wear out and need
replacing, just like the oil filter on your car, for example.
How often they need replacing depends on how much
you spray, the spray materials you use and whether or
not the sprayer is regularly cleaned after use.
Call 1-800-9-SPRAYER or visit www.hdhudson.com
to obtain genuine Hudson® replacement parts. If
you leave your sprayer in the garage over Winter,
particularly in northern areas, the soft parts may dry
out and need servicing before you use your sprayer for
the first time in the Spring.
HOW TO ASSEMBLE
HOW TO PRESSURIZE
Unlock pump handle by pushing down and turning
handle. Do not unscrew pump cap or remove pump.
Using the handle, pump up and down. The more you
pump, the more pressure you will build up inside the
tank. When it becomes difficult to pump, your tank
has reached maximum pressure. Do not stand so
your head is over pump.
• Use low pressure (fewer strokes) for a coarse spray.
• Use high pressure (more strokes) for a fine mist or a
long-reaching stream.
HOW TO FILL
A.) Pour measured amount of spray material into
the open tank.
Follow label directions on
spray material container for amount to use
.
B.)
Add water as directed.
Do not fill beyond the MAX FILL line
.
C.) Insert pump and turn clockwise to seal.

FOR YOUR SAFETY
This sprayer operates with liquid under pressure. Failure
to observe cautions and follow instructions for use and
maintenance can cause tank, hose or other parts to
become corroded, weakened, and/or burst. This can
result in serious injury or property damage from forcible
ejection of parts or high-pressure discharge of spray
material. Do not use any flammables or boiling liquids in
this sprayer as it is not designed nor intended for such
use. Some spray materials can ignite or explode. Do not
spray in an enclosed space, near an open flame such
as found in a bbq grill or water heater, near an electric
motor or open switch, or any source of heat. Do not
smoke while spraying. Use of flammables could result
in serious injury or property damage from unintended
ignition or explosion. Do not use any caustics or acids
in this sprayer, since these can damage or weaken
the sprayer and its parts, resulting in serious injury or
property damage. Keep out of reach from children and
pets. Always read and follow directions on the spray
material container, including the need for protective
clothing. Before using your sprayer, thoroughly inspect
both inside and outside of the sprayer and do not
pressurize sprayer if tank, hose or other parts appear to
be damaged, discolored, brittle, excessively soft or loose.
Do not pressurize with any mechanical device such as an
air compressor, since this can create dangerous pressure
and bursting of parts and result in serious injury. Wear
long-sleeved shirt, pants, gloves, goggles or similar
protective clothing when spraying. PROP 65 WARNING:
This product contains one or more chemicals, including
lead, known to the State of California to cause cancer and
