Warnings
WARNING
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
•
•
Do not operate the unit when fatigued or under the influence of drugs or alcohol.
Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.
•
•
Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information
about your material, request MSDS forms from distributor or retailer.
Check equipment daily. Repair or replace worn or damaged parts immediately with genuine Graco
replacement parts only.
•
•
•
•
•
•
Do not alter or modify equipment.
Use equipment only for its intended purpose. Call your Graco distributor for information.
Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
Do not kink or over bend hoses or use hoses to pull equipment.
Keep children and animals away from work area.

Installation
Installation
suction tube assembly (5c) and screw the suction
tube into the pump inlet (1j).
5. Insert suction tube attached to pump through bung
adapter (9) into tank. Position pump as desired and
tighten union nut (1k) on bung adapter (9).
When unpacking pump, check for shipping damage.
Report any shipping damage to delivering carrier imme-
diately.
Mounting Hose and Nozzle
CAUTION
1. Apply herbicide compatible sealant to male threads
on the street elbow fitting (1e) and screw fitting into
the 3/4 in. npt outlet port on the top of pump. Do not
over tighten.
Do not use a curb pump automatic shut-off nozzle
with this pump. Use of a curb pump automatic nozzle
may cause priming problems, reduced output flow,
and motor overheating. If an automatic shut-off nozzle
is required, use Graco part number 260082 (regular)
or 260083 (unleaded) or Catlow, Inc. part number
NCLF-1 (regular) or NCNLF-1 (unleaded).
2. Apply herbicide compatible sealant to threads on
both ends of the hose assembly. Screw one end of
hose into the female thread on the fitting (1e) and
tighten.
Mounting Pump
3. Screw nozzle onto the other end of hose and
tighten.
CAUTION
•
•
Ensure tank being used is clean and free of welding
slag.
Ensure the tank has a vent to allow air into the tank
as the herbicide is being pumped out. Failure to
vent tank will cause priming problems.
Electrical Installation
12 VDC
To install wiring for a negative ground system:
1. Apply herbicide compatible sealant to large thread
on bung adapter (9) (2 in. x 1-1/2 in. reducer fitting).
Install bung adapter on tank.
1. Ensure pump switch is OFF.
2. To remove electrical cover (2a), remove four bolts
(2c).
2. Assemble suction tube sections by applying PVC
cement (supplied with your pump) to the inside
diameter of the PVC couplers. Make sure PVC
cement is applied to the complete inside diameter
and slide the pipe sections into the coupler with a
twisting motion.
Power cable can be cut to shorter length if 18 feet
(5.5 m) is not required. Cut to proper length and
proceed with steps 3 and 4.
3. Strip 3 in. (76 mm) of outside insulation from power
cable (6c) from end opposite of fuse.
For tanks deeper than 36 in. (914 mm) you will
need a standard 1 in. (25 mm) pipe with 1 in. npt
threads on one end. Suction tubes longer than 60
in. (1.52 m) require a foot valve (Graco Part No.
260217) at the bottom of the tube to prevent loss of
prime.
4. Strip 3/8 in. (10 mm) of insulation from red and black
wires.
5. Slide strain relief (6b) over end of power cable (6c)
on the end just stripped. Male thread of strain relief
should be toward stripped end.
3. Cut the suction tube so that it is 2 in. (55 mm) from
the bottom of the tank when installed in the tank.
6. Insert power cable through conduit thread in electri-
cal cover (2a). Connect wires from power cable to
wires from the motor using wire nuts (2e): red to red
and black to black.
4. Insert inlet gasket (7) into union nut (1k). Apply a
herbicide compatible sealant to the threads on the
4
311628C
Installation
7. Screw strain relief (6b) into electrical cover (2a).
6. Insert electrical power wire through conduit opening
in back of pump.
8. Position power cable (6c) so the large diameter of
power cable extends through strain relief (6b).
7. Using wire nuts (2e), connect wires: green to green,
white to white, and black to black.
9. Tighten nut on strain relief to form a seal around the
power cable.
8. Replace electrical cover.
10. Reinstall electrical cover (2a) on the pump.
Priming Pump
11. Remove 1/2 in. (13 mm) of insulation from wires on
the fuse holder end of the power cable.
1. All pump models will prime with no fluid in the
pumping chamber to a height of 5 ft (1.52 m). If
pump fails to prime, remove hose from street elbow
fitting on pump outlet and pour 8 oz (0.24 liter) of
motor oil into the pump outlet port.
12. Attach battery clamps (6a) with red sleeve to red
wire and black sleeve to black wire. Wire must be
crimped to the battery clamp firmly to get a good
electrical connection.
2. If suction height is too great, the pump may lose its
prime if the nozzle is opened with the pump turned
off.
13. Connect red wire with fuse holder inline to positive
battery terminal. Connect black wire to negative bat-
tery terminal.
3. To hold fluid in the suction tube, a check valve
(Graco Part No. 260217) may be required on the
bottom of tanks with a suction height over 5 ft (1.52
m).
Electrical Installation
115 VAC
4. The tank must be vented or the pump may not prime
or may lose its prime due to a vacuum in the tank.
On 115 VAC pumps, electrical connections must be
made by a licensed electrician per requirements of
local, state, and national codes regarding class 1,
group D installations. Only rigid conduit with
threaded connections should be used. Conduit
opening in pump must be sealed with waterproof,
herbicide-resistant sealant. Failure to comply with
this warning could result in injury from electrical
shock.
1. Ensure pump switch is OFF and electrical power is
disconnected.
2. Install conduit and user-supplied power cord to
pump.
3. Strip 3 in. (76 mm) from power cord jacket and 1/2
in. (13 mm) from individual conductor insulation.
4. To remove electrical cover (2a), remove four bolts
(2c).
5. Remove 1/2 in. (13 mm) of insulation from power
wires inside pump electrical terminal cavity.

Operation
Operation
Maintenance
1. Clean inlet strainer (3b) after every 50 hours of
operation.
Before servicing, turn pump off and open the
nozzle to relieve pressure.
2. To remove inlet strainer (3b), remove four screws
(3c) and strainer cover (3a). Remove and clean
strainer.
CAUTION
Do not operate pump dry. Do not run pump for more
than 5 minutes with nozzle closed. Do not operate
pump for more than 30 minutes continuously in 1 hour.
3. If strainer is excessively dirty, clean tank to protect
pump and the equipment.
4. After cleaning strainer, replace strainer and cover.
Make sure cover seal (3d) is in place.
On/Off switch lever (8d) is located under nozzle holder.
Remove nozzle before turning pump on.
Flushing Pump
1. Move switch lever (8d) on.
Proper flushing of pump after use with herbicides and
chemicals is essential for long service life. Many herbi-
cides dry quickly and will make pump inoperative if
allowed to dry inside pump.
2. Insert nozzle into tank and actuate nozzle lever to
dispense herbicide.
3. Immediately after dispensing herbicide turn switch
lever (8d) off.
CAUTION
All fluids pumped must be compatible with wetted
1. Remove pump from tank and insert suction tube into
water or chemical agent recommended by chemical
manufacturer.
2. Operate pump until fluid discharge is free of chemi-
cal.
3. For extended storage after use with herbicide or
chemical, flush pump and fill with diesel fuel.
