The following trouble checks will help you correct the most common problems encountered with the Lane Liner unit. Should any problem persist after you have made these checks, consult your nearest LEVAB dealer.
Before proceeding with these trouble checks, first check if the power cord is firmly connected to a live power outlet.
The start indicator 
, the error indicator 
or both do not light up when the system
is switched on.
There are two possibilities:
· The start-indicator is flashing: while conditioning the lane the power
was cut off. For more information see below.
· One or more lights are defective. Replace the broken bulb
(component no. 1422, can be ordered from your LEVAB dealer or
directly from Levab International).
The error indicator is shining continuously.
The level of the oil in the internal oil tank is running low. As
soon as this happens another approx. 10 lanes can be treated; as
long as the start indicator is on at least one lane can be treated. If the start
indicator goes off,
the system will not respond to the start button 
until oil has been supplied.
Turn off the power and re-fill the oil. For further instructions see 'Supplying Oil' on page 11.
The error indicator is flashing (three flashes per second)
The cleaner fluid in the stripper unit is running low. As soon as
this happens one more lane can be stripped. After that the system
will not respond to the start button until cleaning fluid has been supplied.
The error indicator 4 is blinking (once a second a short
blink: )
A failure has been detected. There could be various causes:
· The battery of the built-in computer has run out. The battery
has a service life of approximately 5 years.
· The air pressure is not building up; there is possibly a leak
in one of the air tubes.
· The squeegee is stuck.
· The end-of-lane switch in the stripper unit is broken.
To analyse the problem cause, hook up on your MS-Windows PC,
laptop or notebook computer and run the 'Liner Panel' software.
Upon connection, the software will immediately analyse the
situation and display the most probable cause.
If the battery has run out, the indicator will start to flash about 30 days before the battery fails. The system will continue to work until the battery fails completely. Please contact your LEVAB dealer to have the battery replaced. A new battery (component no. 1433) can be ordered from your LEVAB dealer or directly from Levab International.
If the air pressure is not building up, the Lane Liner will keep on running as normal. The pattern of the applied oil might, however, be severely distorted.
If the squeegee is stuck or the end-of-lane switch in the stripper unit is broken, the Lane Liner will only oil the lane. Stripping is then impossible.
After power up the start indicator is flashing.
While conditioning the lane the power was cut off (for example
because the power cord was jammed and has pulled the plug from
the connector). The last position on the lane is kept in memory;
briefly press the start button 5 to resume the
conditioning session. To abort the session, hold down the start
button for approx.
2 seconds until the air pump is switched off.
During a conditioning session the unit stops running, but
the start indicator
keeps on flashing
The unit has been jammed and the built-in jamming protection has
switched off the drive motor. Remove the obstruction and briefly
press the start button to resume the conditioning session. To abort the
session, hold down the start button for approx. 2 seconds until the air pump
switches off.
