Hydra Sprayer Manual 5

Your MS040 Hydra 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 MultiSpray 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 includes a maneuverable 1.5 hp sealed electric motor and a close-coupled pump capable of 4
gpm and 550psi, 50 gallon tank, and cart featuring rear casters, a convex reel with a separate lock and variable
drag system, 150 feet of high pressure spray hose, and a variable pattern trigger spray gun.
START UP
1. Connect the sprayer to a 120 Volt, 60 HZ, 15 amp,
grounded circuit using the cord and plug provided.
Keep all electrical connections away from liquids.
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
S T A R T position. (A). Do Notattempt 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.
NOTE: If an extension cord is used it should be made
of 14 AWG wire or larger and should not exceed 100
Feet in length.
CAUTION: Keep all electrical connections away from
liquids. Use only three–pronged grounded receptacles
and extension cords.

Introduction
Assembly & Preparation
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)
C A U T I O N: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)

Operation
SHUT-DOWN
1. After spraying until the tank is empty, turn the unit
off.
2. Add clear water to the tank. Start the machine and
spray until empty flushing out the pump hose and
gun.
3. Clean any residue from the unit.
4. Return the regulator to the START position.
5. Store the unit in a clean dry place.
6. Do Not allow the unit to freeze as any water left in
the unit will expand and damage the machine.

Hydra Sprayer Manual 8
Maintenance & Cleaning
1. Periodically check the pump oil level (G) If it is
below the indication add oil though the filler (H).
Use only Shell “Tellus #32” hydraulic oil or
equivalent.
2. Periodically lubricate the grease fittings on the
wheels (I &J) 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. (K)
4. Thoroughly clean the in-line filter, tank and
machine on a weekly basis. (L)
5. To drain tank, rotate the drain valve (M) 180° until
the arrow on the valve handle indicates the direction
of flow is out the drain hose. *After draining, turn
the valve back to the Spray position. This
ensures that upon refilling the tank- the chemical
will not drain out of the unit.

Chemical Mixing Procedure
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 S T A R T (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.
