Product Presentation
The LPA2 - Aviation Edition is designed to measure and quantify the numbers of solid contaminants in Hydraulic, Lubrication and
Transmission applications. The LPA2 - Aviation Edition is designed to be a laboratory accurate instrument suitable for “on-site’’
applications utilising mineral oil as the operating uid. Please contact local sales ofce for other operating uid options.
The instrument uses the light extinction principle whereby two laser light systems shine through the uid and lands on photodiodes.
When a particle passes through the beam it reduces the amount of light received by the diode, and from this change in condition,
the size of the particle can be deduced.
Hydraulic and lubricating ystems consist of sets of continuously moving metal parts, which use hydraulic uid as the power
medium. Hydraulic uid is also used to create a lubrication lm to keep the precision parts separated and it is also used as a cooling
medium. The very nature of a hydraulic system is that it produces solid par- ticulate contaminants and these are ever present in all
hydraulic systems. There is a revised standard ISO cleanliness code ISO 4406 which classies the numbers of particles that can be
tolerated within the system and it is these levels of contaminants that the par- ticle counter is designed to measure.

1.2 Operator position and dangerous areas
No operator is required for operating the unit. However, the following areas are to be considered dangerous: The ones
close to the electric motor because of live equipment with potentially hot surfaces.
1.3 Dangers and hazards that cannot be eliminated
- Electric shock risk on the electric motor; in case of motor malfunction
- Burn risk because of high temperatures
- Accidental oil leaks with consequent risk of slipping
- Hose breakage and resulting lubricant loss
- With oil temperatures exceeding 40/45 °C, it is vital to be extremely careful when handling the metal lances/the hoses and
when moving the unit. Avoid direct contact with hot oil and with the lter body.
ALL EQUIPMENT SHOULD BE ALLOWED TO COOL PRIOR TO HANDLING, AFTER IT HAS BEEN IN USE
1.4 Personal Protective Equipment
When operating the unit, personnel must be wearing safety shoes, gloves and goggles. In general, the PPEs to be used according

GENERAL WARNINGS
1.5 Precautions related to product handling of the LPA2 - Aviation Edition
Battery
• It is recommended that the LPA2 - Aviation Edition be charged for a minimum of 24 hours prior to rst use, to fully charge the
internal battery
Internal cleaning
• Do NOT clean the LPA2 - Aviation Edition or Bottle Sampler with Acetone or similar solvents that are not compatible with the
seals in the LPA2 - Aviation Edition. The recommended cleaning uid for internal ushing is Petroleum Ether - see also Fault
Finding, page 44.
• Note: it is not always necessary to clean the unit between uses. The 30 second automatic pre ush is sufcient to purge any
previously sampled uid from the unit and its associated accessory hoses.
• The use of a 500μm coarse screen lter, screwed onto the HP connector, is recommended for heavily contaminated systems.
Refer to section 8.1 for the part number.
LCD visibility
• If the LCD screen remains blank then refer to page 34 for recharging instruction. To improve the LCD screen visibility, the
Analyser can be inclined by unlatching the two extension feet tted to the bottom of the case.
