GENERAL SERVICE INFORMATION -
Cont’d
Depress each of the buttons on the AE-70V2 foot control to
verify that they control motor direction, turn the pump
On/Off, and step through the torque settings and presets
correctly (see Fig. 6) (
refer to “VARIABLE-SPEED FOOT
CONTROL OPERATION” section in the Operation Manual
for complete instructions on setting up and operating the
foot control).
The above procedures describe basic inspection and
verification of the AEU-7000L/7000E. If the unit performs
normally during calibration and setup, and all the key pad
buttons function properly, no further testing of the console
is needed. If the unit does not perform as required, further
diagnosis and service of system components is required.
Use the Troubleshooting sections in this manual as a
guide to diagnose problems and perform repairs.
Cleaning and Lubrication
When servicing the AEU-7000L/7000E unit, the parts of
any component disassembled should be thoroughly
cleaned and inspected before reassembly. A mild
detergent solution is an effective cleaner on all non-
electrical parts. Abrasive cleaners have the potential to
damage surface finishes and should be avoided. Any
wiping should be done with a soft lint-free cloth.
Electrical parts should be cleaned with an appropriate
electrical parts cleaner or air.
Refer to “STERILIZATION & MAINTENANCE” Sections,
pages 21 & 22, in this manual for additional cleaning
instructions.
ESD PRECAUTIONS
The following electrostatic controls must be used when
working on this unit:
ESD Training and Standards:
Employees handling electronic sub-assemblies and ESD
sensitive components are expected to be trained.
Training should be based on IPC-A-610 or equivalent
ESD standard ANSI/ESD-S-20-20 – Protection of
Electrical and Electronic Parts, Assemblies and
Equipment.
ESD Static Controlled Area:
Areas that are designated for handling and working on
electronic sub-assemblies or their components should be
marked off with signs indicating the area where ESD
controls are to be enforced. These areas are to be kept
clear from persons that are not trained to prevent ESD
damage from occurring.
ESD Environment:
The work area is to be free of all static generating
materials, such as plastic containers, water bottles, plastic
bags, plastic objects, such as plastic pens, heat guns
(unless made for the ESD environment).
ESD Jackets:
Clothing should be non-static generating (cotton).
Static generating clothing (e.g. wool, acrylic, nylon) must
be covered with an ESD jacket that is buttoned closed.
Optional gloves:
Nitrile gloves may be used to cover the hands when
working, but are not required.
Seating:
ESD Chairs should be used in place of static generating
chairs (e.g. modern office seating use static generating
materials).
Storage and packaging:
All circuit boards and components are to be stored on or
in static dissipative or static shielding material, throughout
shipping and storage.
ESD Wrist Strap and Mat Routine Checks:
The wrist strap should be checked daily using an ESD
wrist strap testing station. See chart below.
ESD mats should be checked at least quarterly.
