Weekly Maintenance - Prochem SP500 POLARIS 500 Operating & 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 coupler (Solution hose
connection)
Spray with WD-40 or equivalent lubricant to prevent
coupler from sticking.
HOW TO RELEASE THE MOTOR
HOUSING
!! CAUTION - ONLY QUALIFIED MAINTENANCE
PERSONNEL SHOULD UNDERTAKE THE
FOLLOWING PROCEDURE
1. Make sure that the power cable is
unplugged from the power socket.
2. Drain the solution tank.
3. Set the handle to the low position and lock
it in place.
4. Carefully raise the dome and remove the
recovery bucket(s).
5. Return the handle to the upright position
and lock it in place.
6. Tilt the machine backwards and
downwards until the cord wrap meets the
working surface.
7. The underside of the machine should now
be vertical with the brush uppermost.
8. Locate the screw (Philips head) or 7/16 AF
hex bolt at the top of each long frame tube
almost where the tube meets the brush
housing.
9. Carefully undo and withdraw the two
screws/bolts making sure to support the
brush housing when the second screw is
loosened (the whole of the lower part of
the machine pivots on the rear axle and
may drop down suddenly if unsupported).
10. Lower the brush housing to the working
surface to gain access to all internal items.
11. On 800 and 1200 models remove the two
self-tapping screws on each side of the
blue brush chamber cover to access the
components at the front of the machine.

SOLUTION PUMP
!! CAUTION - ONLY QUALIFIED MAINTENANCE
PERSONNEL SHOULD ATTEMPT THE
FOLLOWING REPAIRS
A diaphragm type pump is fitted to the Polaris
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.
CHECK VALVE ASSEMBLY
-
DIAPHRAGM
-
- CAM DRIVE BEARING
- MOTOR
In the event of a reduction in operating pressure,
leakage or pump failure, refer to the 'Fault Finding
Guide' and contact your Prochem Distributor.
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.
