LWP 2, LTP 3
Standard mineral or synthetic oil can be used. Make
sure to only use clean oil and filling equipment.
When the machine is used continuously, the oil
temperature will stabilise at a level which is called
the working temperature. This will, depending on the
type of work and the cooling capacity of the hydraulic
system, be between 20-40°C (68-104°F) above the
ambient temperature. At working temperature, the
oil viscosity must lie within the preferred limits. The
viscosity index indicates the connection between
viscosity and temperature. A high viscosity is
therefore preferred, because the oil can then be used
within a wider temperature range. The machine shall
not be used, if oil viscosity fails to remain within the
permitted area, or if the working temperature of the
oil does not fall between 20°C (68°F) and 70°C
(158°F).

Operation

WARNING Involuntary start
Involuntary start of the machine may cause injury.
Keep your hands away from the start and stop
►
device until you are ready to start the machine.
► Learn how the machine is switched off in the event
of an emergency.
Stop the machine immediately in all cases of
►
power supply interruption.

Preparation before starting

The following checks should be made each time you
start to use the pump. All these checks concern the
serviceability of the pump. Some concern your safety:
● Clean all safety stickers. Replace any that are
missing or cannot be read.
Inspect the hoses generally for signs of damage.
●
● Remove the protective caps from the quick-release
couplings.
Clean the quick-release couplings if needed and
●
connect the tail-hose to the extension hoses of
the power source.
Connect the tool.
●
● Ensure that the hydraulic couplings are clean and
fully serviceable.
● The correct rotation is counter clockwise seen
from below. If rotation is clockwise, check the
hoses. Incorrect connection may result in leaks
and damage to the hydraulic motor.
Grease the bearing in the pump housing through
●
the grease nipple in the bearing housing (3
strokes). All quality types of grease are applicable.

Original instructions
Safety and operating instructions
The suction strainer and base plate must always
●
be fitted to the pump.
● Ensure that any power source you plan to use is
compatible with the pump model used, see the
"Technical data". Atlas Copco recommends using
an LFD oil flow divider, if the flow from the power
source can exceed the maximum allowed oil flow.
WARNING Whipping hydraulic hose
Hydraulic hoses under pressure can whip
uncontrollably if screws loosen or are loosened. A
whipping hydraulic hose can cause severe injuries.
► Depressurise the hydraulic system before
loosening the connection of a hydraulic hose.
Tighten the nuts on the connections of the
►
hydraulic hoses to the required torque.
Check that the hydraulic hose and the connections
►
are not damaged.

Start and stop

Starting the pump

Start the power source and allow it to run for a few
●
minutes to warm up the hydraulic oil.
● LTP 3 pump only: Attach a rope or other device
to the handle of the pump and lower the pump into
the water.
● Activate the control valve of the power source to
start the hydraulic oil flow.

Stopping the pump

When pumping is complete, activate the control
●
valve to stop the hydraulic oil flow.
Stop the engine of the power source.
●
● Disconnect the hoses and fit the protective caps
to the quick-release couplings.

Connecting hoses

Prepare the power source
Turn the by-pass valve to the OFF position.
♦
Stop the engine.
♦
Inspect the couplings
♦ Make sure the couplings are clean and
serviceable.
Connect the hoses to the pump
♦ Attach the return line hose.
♦ Attach the feed line hose.
♦ Rotate the collar on the female coupling to secure
the coupling.
