Value 3 - Warning given when service counter has reached CHECK UP 
HOURS value. After 10 hours continued operation the maximum speed 
will be reduced. After 20 hours continued operation all truck operation 
will be blocked.
The warning for “time for service” is:
• An audible alarm signal from the transistor regulator.
• The status LED on the transistor regulator will flash 3 short + 8 long.
• The battery charge status [H81] LED flashes continuously.
“Time to next service” (CHECK UP HOURS)
Set this value to correspond with number of hours truck activity must 
increase by when the next service warning must be given.
Time to next service = 200 + (p X 50) hours, where p = parameter value.
12.10.5 Transferring parameter sets
General
The Hand terminal can be used to save a parameter set and configura-
tion from a truck. This is useful in the following cases:
• To restore a truck’s configuration to a known state or after replacing 
the transistor regulator.
• To transfer the configuration from one truck which has been config-
ured to a complete group thus ensuring all trucks are identically con-
figured.
The hand terminal can store up to a maximum of 32 unique parameter 
sets.
