HT8 Multi-Speed Service Indicator Light
1. To help assist in scheduling routine servicing and
maintenance the 8 Multi-Speed has a run timeHT
clock built into the Multi-Speed Control Unit.
The run time clock records the time the 8HT
motor runs and stores the total run time in
memory even when the 8 is disconnectedHT
from the power supply.
Two run time intervals of 100hrs or 300hrs can
be set by the operator. When the run time
interval set is reached the ‘green’ power
connected light flashes 4 times when the 8 isHT
first connected to the power supply. The light will
then remain to indicate that power isON
connected (see illustration below).
The run time can not be reset until the interval set
(100hrs or 300hrs) has been reached. The green
power connected light will only flash when the
power is first connected and the set number of
run time hours has been reached. At all other
times the green power connected light will come
ON without flashing when the power supply is
connected.
From new the run time clock is set to indicate
300hrs of run time. When this pre-set time is
reached the green power connected light will
flash when the power is connected.
On completion of any service work the run time
clock maybe reset to 300hrs or 100hrs at the
owners/operators discretion.
It is recommend that if the 8 is owner operatedHT
that the run time is reset to 100hrs after the initial
300hr run time until new motor brushes are
fitted. When new motor brushes are fitted it is
recommended the run time is reset to 300hrs.
If the 8 is part of a hire or rental fleet it isHT
recommend that the run time is reset to 100hrs at
all times to provide for more regular servicing as
demanded by the hire and rental market.
CAUTION - the run time indicator is
provided as a reminder to the
operator/workshop that the 8 requiresHT
a ‘full’ service paying particular attention
to the service areas detailed on the
fallowing pages. Routine maintenance
should be carried out on a regular basis
with special attention paid to guards,
cables and general mechanical
components.
Note: When a new Multi-Speed Handle Assembly or
new Multi-Speed Control unit is fitted carry out a full
service including replacing all four motor brushes.
This service will then match the initial 300hrs service
interval as set from the factory.
