EHTMA category

The machine is clearly marked with EHTMA
categories. It is important that any power source used
is in a compatible category. If any doubt, consult an
authorised supervisor.

Installation

Performance

To achieve standard performance, the Atlas Copco
LWP 2 water pump requires a nominal oil supply of
20 lpm (5 US gal/min) at a pressure of min. 100 bar
(1400 psi), and the LTP 3 trash pump requires a
nominal oil supply of 30 lpm (8 US gal/min) at a
10
pressure of min. 140 bar (2000 psi). The hydraulic
oil filter must have a filter rating of 25μ or higher.
H: Head (metres)
Q: Performance (litres per second)
The above data are based on nominal oil supply and
pressure, see "Technical data".

Hoses

For connection on the machine, the hydraulic hose
must be approved for a working pressure of at least
160 bar (2300 psi) and have a ½" inner diameter. To
resist exterior wear and tear, we recommend using
a 2-layer hydraulic hose. The machine connection
marked P (pump) is the oil inlet, and the connection
marked T (tank) is the oil outlet. Always connect both
hoses and make sure that all hose connections are
tight. Never carry the machine by the hose.

Quick-release couplings

The original Atlas Copco hydraulic hoses are fitted
with Flat-Face quick-release couplings that are strong
and easy to clean. The quick-release couplings are
fitted so that the male connection supplies oil and
the female connection receives oil.
NOTICE Wipe all couplings clean before
connecting. Ensure that couplings are clean and
correctly engaged before operation. Failure to do so
may result in damage to the quick couplings and
cause overheating and cause foreign matter to enter
the hydraulic system.

Hydraulic oil

In order to protect the environment, Atlas Copco
recommends the use of biologically degradable
hydraulic oil. No other fluids should be used.
♦ Viscosity (preferred) 20-40 cSt.
♦ Viscosity (permitted) 15-100 cSt.
♦ Viscosity index Min. 100.
