Hydra Sprayer Manual 5

Your Spraytrax comes to you ready to spray. After removing the sprayer from the crate, check
the tank for any additional parts and accessories. Connect the spray gun to the hose using
the quick disconnect. Your machine is now ready for use.
The Dramm Hydra SprayTrax™ is a hydraulic sprayer that offers a variety of flow rates with
a variety of pressures to allow for maximum flexibility. The Hydra can apply all formulations
of chemicals including insecticides, fungicides, Insect growth regulators, plant growth
regulators, and disinfectants. The Hydra can output all formulations without damage or
corrosion to the pump.
The Dramm Hydra SprayTrax includes either a 1.5 HP electric motor or a 5.5 HP Honda
gasoline motor and a
close-coupled pump capable of 4gpm electric or 8 gpm gas and 550psi, 50 or 100 gallon
tank, maneuv erable SprayTrax™ cart with self-tracking axle design, a convex reel with a
separate lock and variable drag system, 250 feet of high pressure spray hose, and a
variable pattern trigger spray gun.
START UP
1. Either switch on the electric motor or Pull-
start the Honda motor by setting the motor
speed to fast & engaging the choke. for
more on motor operation see the motor manual
pg 15.
2. Fill the sprayer to the desired level. Do Not
operate the sprayer empty for more than a
few seconds. The water acts as a coolant
and lubricant for the pump and damage
may occur.
3. Start the sprayer with the pressure control
knob in the START position. (A). Do Not
attempt to start the sprayer under pressure
as this will stall the motor and cause an
overload condition.
4. After starting the sprayer allow it to run with
the pressure control knob in the start
position. This will remove any air from the
system, which can harm the pump.
5. Engine speed should not exceed 3,500
RPM. Maximum speed should be set using
the adjusting screw located directly above
the throttle lever of engine.

Introduction
Assembly & reparation
NOTE
Always start and shutdown your sprayer
with the pressure regulator in the START
(priming) position.
Keep inlet filter clean.
Always rinse the tank and flush the pump
with clean water after each use.

SPRAY OPERATION
1. After following the start up, to increase the
spray pressure, turn the pressure control
knob to the desired setting. (B) You may
use any of these settings for spraying, as
the unit will operate properly at all settings.
2. To begin spraying, pull the lever to the gun.
A latch is provided to hold the level open
to reduce operator fatigue. (C)
CAUTION :Do not direct the spray at
yourself or others, as injury may occur. On
higher pressure settings, the spray stream
may cut or inject spray under your skin.
Always wear proper personal protective
gear when spraying.
3. Spray Pattern: Adjustment of the spray
pattern is made using the lever on the side
of the gun. The pattern will adjust from a
straight stream to a fine cone mist. (D)
4. Hose Reel: The Hydra MultiSpray comes
standard with a variable drag lockable
hose reel. The reel may be locked in
position to prevent the hose from
unwinding further than wanted. (E) The
variable drag on the reel places variable
tension on the reel to prevent freewheeling
of the reel during unwinding. The drag has
a lever to activate it. A nut allows for
tension adjustment. (F)

Chemical Mixing rocedure
Maintenance & Cleaning
1. Periodically check the pump oil level(G)
If it is below the indication, add oil though
the filler (H). Oil should be changed after
the first 50 hours of operation. Use 10 w 30
oil, preferrably non-detergent.
2. Periodically lubricate the grease fittings
on the wheels with a good grade of
bearing grease to extend the wheel
bearing life.
3. Replace the spray gun tip every season.
As the hole in the tip gets larger the spray
pressure drops and degrades the quality
of the spray. ( )
4. Thoroughly clean the in?line filter, tank
and machine on a weekly basis.
5. To drain tank, rotate the drain valve (L.)
90° allowing flow from the drain hose. To
completely drain tank, remove the lower
housing of the in-line filter (M). *After
draining, clean the filter, replace the
housing and close the drain valve (L) to
ensure that upon refilling the tank? the
chemical will not drain out of the unit.
H.

K.

M.
1. Fill the sprayer tank at least 3/4 full with water ONLY.
2. Dilute (mixing to dissolve) chemicals with water in a 5 gallon bucket. Never put
concentrated chemical formulations directly into the tank without diluting with water.
3. Start sprayer with pressure regulator in START (priming) position to beginagitation process
prior to adding chemical to sprayer tank.
4. Pour chemical and water mixture (slurry) into the sprayer tank, filled 3/4 full of water, after
agitation has begun.
5. Fill remainder of sprayer tank with water.
