Front and Rear Panels
Cleaning
• Do not use any solvents or abrasive cleaners on the any
of the panels (including the LCD display).
• Do not spray any cleaning product directly on the pan-
els.
To remove dust, first try gently dusting with a microfi-
ber cleaning cloth. If further cleaning is needed, apply
a small amount of screen cleaner to a soft microfiber
cloth. Then, clean the panels/LCD display with the
moistened cloth.
Screen Cleaning Solutions:
Make your own: Mix distilled water and white vinegar
in 1 to 1 proportions. Pour this mixture into a spray
bottle from which it can be used, or
Buy a cleaning solution: There are several on the market
suitable for cleaning LCD screens.
• Do not spray or apply cleaner directly on the genera-
tor.
• Do not allow any liquid to collect around the AC power
switch.
Display
Do not apply any pressure to the display.
Control Keys/Buttons
Control keys/buttons will respond to firm, gentle finger
pressure. Please do not use sharp objects on the keys/
buttons.
Chassis
Sheet Metal Cover
The cover is preformed to fit over the chassis and has
protective grills over the cooling air vents. Keep the cover
on at all times because there are high voltages present
which could cause injury. The internal case also contains
capacitors which continue to hold a high electrical charge,
even after the power is shut off.
Air Ventilation Slots
Keep the ventilation slots free from obstructions. If
excessive dust or dirt collects on the slots, wipe or vacuum
them clean. Do not use compressed air to clean them as
this may force the dirt inside the chassis.
Allow 5 inches (127 mm) of clearance outside each
ventilation slot.
The air intake is on the right, and the exhaust is on the
left. This is shown in Figure 3 - 3, Page 15.
I/O Connector
The Input/Output connector has a pair of 4-40 threaded
jack screws to secure the connector. Make sure the screws
are snug, but do not overtighten them.
AC Power Cord
The AC power cord should be kept in good condition and
free from any cuts. The AC plug should be straight with
no bent prongs.
WARNING
Never operate the gen-
erator with the cover
off. This is an unsafe
practice and the high
voltage present may
cause injury.
