pressing the increase or decrease buttons will activate the display and it will work as
normal.
When replacing batteries use two industrial alkaline "D" cell batteries. These are accessed
by removing the cover of the electronics box fastened to the frame of the machine. To
remove the cover, pull or pry the sides of the cover outward to free the detent boss from
the holes in the body of the box. No removal of screws is necessary.
When the batteries have been replaced the display will run through a self check flashing a
series of numbers. Once the test sequence stops and the display shows "off" the
equipment is ready to use.
AIR HOSES AND FITTINGS
COMPRESSION FITTINGS
All KEISER machines use polyethylene tubing and "compress-align" fittings to connect
the various pneumatic components within the machine.
If an air leak is suspected, first listen closely to the air hose connections. Leaks will make
a hissing noise. Very slight leaks may not be loud enough to hear. These may be detected
by dabbing soapy water on the suspected leak. Escaping air will make bubbles. If the leak
is at the fitting, first tighten the nut no more than one-quarter of a turn. Test the
connection again. If the fitting still leaks, the nut must be replaced. In most cases the air
hose should be long enough to allow this, if not, order a new air hose from KEISER.
To install a new hose, fitting or nut:
1.
Cut the tubing as close as possible to the nut. The cut must be clean and square.
2.
Slip a new nut over the tubing.
3.
Insert the tubing into the fitting all the way to the shoulder inside the fitting
(see cutaway illustration).
4.
Hold the tubing in the fitting and slide the nut down onto the fitting. Tighten the
nut as tight as possible with the fingers, then one full turn with a wrench.
