INTRODUCTION
The Model 60 series GunJet®is a heavy-duty, impact resistant spray gun with a
sturdy nylon handle and trigger guard. The Model 60 GunJet is a high-pressure
spray gun, which remains responsive and easy to operate even at maximum
flow and capacity conditions. The light trigger pull provides positive control.
The heat resistant handle remains comfortable even at high temperatures. A
special trigger lock feature locks in the “off” position to prevent accidental
discharge and retracts flush into the handle when the gun is in use. The Model
60W incorporates a continuous “weep” feature to minimize the change of
freezing and, with the exception of the valve seat subassembly, the 60 and
60W GunJet spray guns are identical and require the same installation and
operating procedures. The Model 60 and 60W GunJet spray guns will
accommodate standard Spraying Systems Co. accessories for both the inlet and
the outlet connections within the accessories’ pressure and temperature
limitations.
Features of the Model 60-GunJet spray guns:
•Operating pressure range up to 2500 psi (173 bar).
•Flow capacities to 6 gpm (23 l/min) with 90 psi (6 bar) pressure drop.
•Maximum recommended temperature 300°F (150° C).
•Single piece, forged brass inlet body (for 60 & 60W).
•Stainless steel inlet body (for 60 SS & 60W SS).
•Stainless steel shut-off needle.
•Bronze-filled PTFE valve seat.
•Viton stem seal with PTFE back-up ring.
•Short hand grip (handle to trigger).

WARNINGS & PRECAUTIONS
IMPORTANT: READ ALL INSTRUCTIONS BEFORE USING SPRAY GUN
THIS IS A HIGH-PRESSURE DEVICE WHICH SHOULD ONLY BE USED IN A
PROPERLY ENGINEERED SYSTEM. THIS SPRAY GUN SHOULD BE OPERATED
ONLY BY TRAINED OPERATORS AND KEPT OUT OF REACH OF CHILDREN.
PLEASE READ THE FOLLOWING INSTRUCTION SHEETS BEFORE ATTEMPTING
TO OPERATE THE MODEL 60 HIGH PRESSURE GUNJET SPRAY GUN.
HEED ALL THESE WARNINGS or serious and permanent injury may result.
1. DO NOT aim gun at any person or any part of the body. Fluids under
high pressure can penetrate the human skin and can cause severe
injury, possibly resulting in amputation or death. Hot liquids and
chemicals can also cause burns or injury. If any part of the body comes
in contact with the spray stream, immediately consult a physician.
2. DO NOT at any time place hands or any other part of the body in front
of spray nozzle or tip.
3. DO NOT alter equipment in any manner; if repairs are necessary, use
only genuine factory repair parts supplied by Spraying Systems Co.
4. DO NOT exceed maximum operating pressure of the lowest rated
accessory item within the spray system even though some of the
accessories have a higher maximum pressure rating.
5. DO NOT leave equipment under pressure unattended at any time.
Relieve pressure by shutting off power to pump, turning off the liquid
supply to the pump, and actuating Trigger until all fluid ceases to flow;
then position Trigger Lock to the locked position.
6. DO NOT use damaged, perforated, or weakened fluid hose.
7. DO NOT use a GunJet with a faulty or damaged Trigger Lock.
8. DO NOT operate a spray gun if there are any leaks from the packings,
fittings, hoses, etc. Fluids that are under high pressure can penetrate
skin, cloth, etc., and cause serious injury.
9. DO NOT touch any metal parts of the gun or accessories when
spraying hot liquids or severe injury can occur.
10. DO NOT handle a spray gun without a tip or nozzle any differently
than one with a tip or nozzle. Even with the tip or nozzle removed, the
spray gun can discharge a large volume of liquid at a high velocity.

SAFETY SHOULD ALWAYS BE OBSERVED:
1. DO use a two-handed control of Model 60 GunJet at all times. Grasp
spray gun firmly with both hands. If an extension is used, grasp the
extension. (Insulated extension if spraying hot liquids.)
2. DO adopt a secure body stance prior to and during spray operation to
safely control the high reactionary force of this unit.
3. DO impress on other people in the spraying area the importance of
obeying strict safety precautions for everyone’s safety.
4. DO develop a habit of shutting off the power to the pump, relieving
fluid pressure from gun and hose by actuating trigger until all fluid
ceases to flow, and setting the Trigger Lock in the locked position,
before attempting to remove the tip, nozzle, gun or any part of the
gun, or when gun is not in use.
5. DO check operation of Trigger Lock before each spray period. Trigger
Lock must hold the Trigger to its forward position. (Adjust if necessary;
see section Trigger Adjustment Procedure.)
6. DO carefully check and tighten threaded connections regularly. Make
them secure and leak proof.
7. DO flush gun after each spray period using the same safety
precautions as used during spraying operations. Always use the lowest
possible pressure for flushing.
8. DO keep gun clean and dry to allow for positive grip.
9. DO use GunJet in a well-ventilated area and make sure spray gun is
grounded properly when used in a possibly explosive or inflammable
environment. A grounded-type hose should be used.
IMPORTANT: In case of the slightest appearance of skin penetration from
spray, CONSULT A PHYSICIAN IMMEDIATELY!
