energized or under pressure while unattended. Follow the Pressure Relief Procedure
when the equipment is unattended or not in use, and before servicing, cleaning, or
removing parts.
•Check hoses and parts for signs of damage. Replace any damaged hoses or parts.

•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.
PRESSURIZED ALUMINUM PARTS HAZARD
Useof fluids thatareincompatiblewithaluminum in pressurizedequipment can causeserious
chemical reaction and equipment rupture. Failure to follow this warning can result in death,
serious injury, or property damage.
•Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon
solvents or fluids containing such solvents.
•Do not use chlorine bleach.
•Many other fluids may contain chemicals that can react with aluminum. Contact your

Trigger Lock
Always engage the trigger lock when sprayer
is stopped to prevent the gun from being
triggered accidentally by hand or if dropped
or bumped.
Pressure Relief Procedure
1. Engage trigger lock.
2. Ifapplicable,turnelectricmotorON/OFF
switch to OFF position. Wait 7 seconds
for power to dissipate.
3. Unplug power cord or shut engine off.
This equipment stays pressurized until
pressure is manually relieved. To help
prevent serious injury from pressurized
fluid, such as skin injection, splashed fluid
and moving parts, follow the Pressure
Relief Procedure whenever sprayer is
stopped and before sprayer is cleaned or
checked, and before equipment is
serviced.

4. Disengage trigger lock.
5. Hold a metal part of the gun firmly to a
grounded metal pail. Trigger the gun to
relieve pressure.
Solvent and oil-based fluids: follow
local code. Use only conductive metal
pails, placed on a grounded surface
such as concrete.
Do not place pail on a non-conductive
surface such as paper or cardboard
which interrupts grounding continuity.
6. Engage trigger lock.
7. Open any fluid drain valves in system.
Leave drain valves open until ready to
spray again.

1. If applicable, soak leather packings in
SAE 30W oil for one hour before
assembly.
2. Install ball in piston rod. Apply thread
sealant to piston valve threads; ensure
that none gets on the ball.

models torque packing nut to 140 ± 10
in-lbs (16 ± 1 N•m).
13. Storage
Throat Packing Adjustment
When pump packings begin to leak after
much use, perform Pressure Relief
Procedure, page 4, and tighten packing nut
down until leakage stops or lessens. This
allows approximately 100 gallons of
additional operation before a repacking is
required. Packing nut can be tightened
without o-ring removal.
