Vacuum Motor; Weekly Maintenance - Prochem TR300 FIVESTAR Safety, Operation & Maintenance Instructions

WEEKLY MAINTENANCE

At least once a week, inspect the internal
components, solution fittings and electrical
connections. Check for signs of fluid leakage and
tighten or replace fittings as necessary. Make sure
all electrical connections and cables are in place.
Solution Lines and Fittings
Flush the machine with a solution of 1 part water
with 20 parts B109 Fibre & Fabric Rinse in order to
neutralise the alkaline residue left by the cleaning
solution.
Quick connect couplers (Hand Tool connection)
Spray with WD-40 or equivalent lubricant to prevent
coupler from sticking.
SOLUTION PUMP
!! CAUTION - ONLY QUALIFIED MAINTENANCE
PERSONNEL SHOULD ATTEMPT THE
FOLLOWING REPAIRS
A diaphragm type pump is fitted to the Fivestar
machine and requires little maintenance other than
occasional inspection of the pump head to check for
any fluid leakage. The following components
should be inspected and cleaned, or replaced as
necessary. See parts illustration in this manual for
further reference.

VACUUM MOTOR

!! CAUTION - ONLY QUALIFIED MAINTENANCE
PERSONNEL SHOULD ATTEMPT THE
FOLLOWING REPAIRS
The vacuum motor is lubricated for life - no
additional lubrication is required. The only other
maintenance that may be required is changing the
motor brushes. This should only be carried out
by an individual with THOROUGH knowledge of
electric motors.
The brushes should be changed before the
brush wears to within 3/8" of the brass holder.
With heavy usage we recommend that the
brushes be checked every 3 months. The
recommended inspection period for normal
usage is at least every 6 months. The estimated
brush life is approximately 400 to 450 hours, but
inspection and replacement should take place at
least every 350 hours to prevent the possibility
that brush wear may cause damage to the
vacuum motor.
On re-assembly, the lead wires must be kept away
from the rotating parts and the motor frame. Always
ensure that the green earth wire is re-connected to
the vacuum motor body to ensure safe operation.
To achieve maximum life, the brushes should be
seated on the commutator before full voltage is
applied. Do this by applying 50% of the rated
voltage for thirty minutes. In the event of electrical
or mechanical failure, refer to the General Fault
Finding Guide page in this manual and contact your
Prochem Distributor. Although some service parts
are available, we recommend that defective
vacuums be replaced.
