SKIN INJECTION HAZARD

High-pressure spray is able to inject toxins into the body and cause serious bodily injury. In the event
that injection occurs, get immediate surgical treatment.

• Do not aim the gun at, or spray any person or animal.

• Keep hands and other body parts away from the discharge. For example, do not try to stop leaks
with any part of the body.

• Always use the nozzle tip guard. Do not spray without nozzle tip guard in place.

• Use Graco nozzle tips.

• Use caution when cleaning and changing nozzle tips. In the case where the nozzle tip clogs while
spraying, follow the Pressure Relief Procedure for turning off the unit and relieving the pressure
before removing the nozzle tip to clean.

• Do not leave the unit energized or under pressure while unattended. When the unit is not in use, turn
off the unit and follow the Pressure Relief Procedure for turning off the unit.

• Check hoses and parts for signs of damage. Replace any damaged hoses or parts.

• This system is capable of producing 3000 psi (210 bar/21 MPa). Use Graco replacement parts or
accessories that are rated a minimum of 3000 psi (210 bar/21 MPa).

• Always engage the trigger lock when not spraying. Verify the trigger lock is functioning properly.

• Verify that all connections are secure before operating the unit.

• Know how to stop the unit and bleed pressure quickly. Be thoroughly familiar with the controls.

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever
you see this symbol.

This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from pressurized fluid, such as skin injection,
splashing fluid and moving parts, follow the Pressure
Relief Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.

1. Engage trigger lock.

2. Turn ON/OFF switch to OFF.

3. Move pressure control switch to OFF and turn pres­sure control knob fully counterclockwise.

4. Unlock trigger safety. Hold metal part of gun firmly
to side of grounded metal pail, and trigger gun to
relieve pressure.

5. Lock gun trigger safety.

6. Open the pressure drain valve. Leave the pressure
drain valve open until you are ready to spray again.

Maintenance Checklist

• DAILY: Check engine oil level and fill as necessary.

• DAILY: Check hose for wear and damage.

• DAILY: Check gun safety for proper operation.

• DAILY: Check pressure drain valve for proper oper-

ation.

• DAILY: Check and fill the gas tank.

AFTER THE FIRST 20 HOURS OF OPERATION:

• Drain engine oil and refill with clean oil. Reference
Honda Engines Owner's Manual for correct oil vis­cosity.

• WEEKLY: Remove air filter cover and clean ele­ment. Replace element, if necessary. If operating in
an unusually dusty environment: check filter daily
and replace, if necessary.

Replacement elements can be purchased from your
local HONDA dealer.

• WEEKLY: Check level of TSL in displacement
pump packing nut. Fill nut, if necessary. Keep TSL
in nut to help prevent fluid buildup on piston rod and
premature wear of packings.

AFTER EACH 100 HOURS OF OPERATION:

• Change engine oil. Reference Honda Engines
Owner's Manual for correct oil viscosity.

7. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved after follow­ing the steps above, VERY SLOWLY loosen tip
guard retaining nut or hose end coupling to relieve
pressure gradually, then loosen completely. Clear
hose or tip obstruction.

Graco Warranty

Graco warrants all equipment manufactured by Graco and bearing its name to be free from defects in material and workmanship on the date of
sale by an authorized Graco distributor to the original purchaser for use. With the exception of any special, extended, or limited warranty published
by Graco, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be
defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco's written recommenda­tions.

This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by faulty instal­lation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of non-Graco
component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of Graco equipment with structures,
accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or maintenance of struc­tures, accessories, equipment or materials not supplied by Graco.

This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for verification of
the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned
to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs
will be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.

THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIM­ITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

Graco's sole obligation and buyer's sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other remedy
(including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any other incidental or
consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the date of sale.

Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular purpose in connection with accesso­ries, equipment, materials or components sold but not manufactured by Graco. These items sold, but not manufactured by Graco (such as electric
motors, switches, hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide purchaser with reasonable assistance in
making any claim for breach of these warranties.

In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment hereunder, or
the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract, breach of warranty, the negli­gence of Graco, or otherwise.
