2.2 ATP-1500 Safety Precautions
Warning: Failure to observe the following precautions may
result in serious personal injury or death!
• Always wear eye protection, gloves and boots when operating
the pump.
• High pressure hydraulic equipment can be very dangerous if
misused. Keep away from oil leakages at high pressure. Liquid
escaping from highly pressurized equipment has suffi cient
power to penetrate the skin, which can cause blood poisoning.
In the case of such an accident, seek IMMEDIATE medical
attention.
• Never attempt to disconnect a
hydraulic coupler while it is under
pressure.
• Never attempt to repair leaks while
the system is pressurized. Be sure
system pressure gauge indicates zero
[0] psi/bar before making any repairs.
• Never pressurize the back of
a disconnected male
coupler. Serious personal
injury could result if the
coupler fails while under
pressure.
• Use caution when
pressurizing a system.
Pressure can rise faster than
anticipated. Continuously
monitor the pressure gauge
during pressurization. Be
prepared to stop
pressurization immediately
at any time.
• Before operation, ensure that quick-disconnect couplings are
properly connected by physically pulling on them.
• Allow only trained and experienced personnel to operate the
pump. Be especially careful to avoid accidental pump start-up.
• Never leave the pump pressurized and unattended. If you must
leave the area, close the air-shutoff valve and ensure that the
release (return-to-tank) valve on the pump is fully open. Turn
the air pressure regulator knob counter-clockwise until zero [0]
psi/bar is indicated on the air pressure gauge.
• Never exceed the safe working pressure for the hydraulic
hoses, tools or pump. The maximum allowable operating
pressure (hydraulic) for the ATP-1500 pump is 21,755 psi [1500
bar].

Figure 1, Before Connecting Air Supply
• Before connecting air supply: Ensure that the air-shutoff (on-
off) valve is closed (i.e. handle in vertical position) and that the
oil return-to-tank valve is open. See Figure 1.
• Check the air pressure gauge after connecting air supply. If any
pressure is indicated, turn the air pressure regulator knob
counter-clockwise until the gauge indicates zero [0] psi/bar.
• Always pressurize the pump starting at zero [0] psi/bar air
pressure and work upward. Turn air pressure regulator knob
SLOWLY to prevent sudden and unexpected increases in
hydraulic pressure.
• After the desired hydraulic pressure has been obtained, always
close the air-shutoff valve and turn the air pressure regulator
knob counter-clockwise until zero [0] psi/bar is indicated on the
air pressure gauge.
• Always depressurize before leaving the system unattended.
