Operation/Maintenance
Flush Pump Before First Use
The pump is tested with lightweight oil, which is left in to protect the pump parts. If the fluid you are using may be contaminated by the oil, flush it out with a compatible solvent. See Flushing on page 10.
Starting and Adjusting Pump
Before starting, fill wet cup 1/3 full with TSL or compat- ible solvent.
1.Remove tip guard and spray tip from gun. Refer to gun manual.
2.Close air regulator (F).
3.Close
4.Check that all fittings throughout the system are tightened securely.
5.See Fig. 2. Connect the suction hose (T) to pump’s fluid inlet. Place tube into fluid supply. Do not stretch hose tight; let it hang as shown in Fig. 2, to assist fluid flow into pump.
6.Hold metal part of gun (S) firmly to side of grounded metal pail and hold trigger open.
7.Open pump’s
8.Slowly turn regulator knob clockwise increasing pressure until pump starts.
9.Cycle pump slowly until all air is pushed out and pump and hoses are fully primed.
10.Release gun trigger and engage safety latch. Pump should stall against pressure.
CAUTION
Do not allow the pump to run dry. It will quickly accelerate to a high speed, causing damage. If your pump is running too fast, stop it immediately and check the fluid supply. If the container is empty and air has been pumped into the lines, refill the con- tainer and prime the pump and the lines, or flush and leave it filled with a compatible solvent. Eliminate all air from the fluid system.
11.With pump and lines primed, and with adequate air pressure and volume supplied, pump will start and stop as you open and close gun.
WARNING
COMPONENT RUPTURE HAZARD To reduce the risk of overpressurizing your system, which could cause compo- nent rupture and serious injury, never
exceed the specified Maximum Incoming Air Pres- sure to the pump (see the Front page of this manual).
12.Use air regulator (F) to control pump speed and fluid pressure. Always use lowest air pressure necessary to get desired results. Higher pressures cause premature tip and pump wear.
WARNING
SKIN INJECTION HAZARD
The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid
under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:
Dare instructed to relieve the pressure,
Dstop spraying,
Dcheck or service any of the system equipment,
Dor install or clean the spray tips.
Install the Spray Tip
WARNING
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8.
Relieve the pressure by shutting off air valve and then trigger the gun. Install the spray tip and tip guard as explained in your separate gun manual.
