All Prochem machines are engineered and built to
require a minimum of maintenance. But like any
machine, it does require some care to keep it in
optimum working condition. Careful attention to
these maintenance instructions will give you
maximum operating performance and will increase
the life expectancy of the machine.
To ensure a trouble-free machine, we strongly
advise the following preventative maintenance.
DAILY MAINTENANCE
The following should be carried out at the end of
each cleaning session.
POWER CABLE & PLUG
Check the condition of the power cable and plug.
Make sure all wires are correctly located and tightly
connected. If damaged, the power cable and plug
assembly must be replaced.

GENERAL MAINTENANCE
7.
Ensure that all connections are secure and
close machine electrical housing and secure
with tool required.
SOLUTION TANK
Flush the solution tank and pump through with 5
litres of hot water. Check the filters and clean if
necessary. If damaged or compressed, unscrew
the filters and re-shape or replace as necessary.
RECOVERY TANK
Check the foam filter, filter screen and gasket which
is located on the top of the solution tank. Clean or
replace as required and ensure that the recovery
tank fits securely over the filter gasket and provides
a secure seal when the latches are fastened.
Flush through with clean water after each use. For
regular maintenance and internal cleaning of the
recovery tank, a screw-type clear cover is provided
on the rear of the tank. For internal cleaning,
remove recovery tank from the machine and pull the
handle upwards and clear of the window. Unscrew
window anti-clockwise to remove and gain access
to inside of recovery tank. Clean with broad-
spectrum disinfectant before re-assembly.
CLEANING TOOLS AND HOSES
Inspect the hand tool or wand head for sharp edges
or damage. Check the spray nozzle for debris,
correct alignment and spray pattern. Clean if
necessary using only a soft bristle brush - DO NOT
use metal or wire. Rinse the vacuum hose with
hot water to prevent soil build-up. Lubricate the
female quick connect sleeve with WD-40 or similar.
Check all nuts and bolts and tighten if
necessary.
Always keep the machine clean inside and out.
WARNING! FREEZING
PROTECTION
If your Bravo machine is exposed to freezing
weather with solution in the components, the
solution will FREEZE and in most cases
SERIOUSLY DAMAGE the machine. To avoid
damage, consider the following in the winter
season. When the machine is not in use, store it in
a heated building. To avoid freezing between jobs,
pump out all the cleaning solution from the machine
and hand tool and make sure that the machine and
hand tool are insulated from the vehicle floor (wrap
in a blanket or tarpaulin).
