UNDERSTANDING YOUR SOIL EXTRACTOR
OVERVIEW
The Bravo extraction machine consists of two
mechanical parts, a solution pump and fan type
vacuum motor - both operated by a combined
electrical switch located on the back of the main
housing. Switch position (I) operates the vacuum
only and switch position (II) operates the vacuum
and pump simultaneously. The pump forces a
cleaning solution under pressure from a housing
tank to the face fibre of the carpet or fabric via a
solution feed hose and cleaning tool. The cleaning
tool has a spray jet system that is compatible with
the pressure from the pump and delivers just the
right amount of solution to the carpet or fabric. The
solution has a short amount of time to be forced into
the fibres and emulsify the soil particles before it is
extracted by the powerful suction of the vacuum
motor. Because both these functions take place
at the cleaning tool, it will soon be realised that
the speed at which the operator moves the
cleaning tool is an important factor.
RECOVERY SYSTEM
The recovery tank on the Bravo does not have a
built-in shut-off system and relies on the recovery
tank capacity being greater than the solution tank
capacity.
With this in mind it is important to understand that
the recovery tank must be emptied each time the
solution tank is re-filled. The design of the Bravo
ensures that the recovery tank must be removed for
emptying before the solution tank can be re-filled.
Care should be taken to empty the recovery tank
frequently and to use a defoamer if heavy foam
build-up occurs due to previous shampoo residue in
the carpet. After emptying the recovery tank, flush
through with clean water before re-fitting the
Bravo Manual 1/7/15
recovery tank to the machine. 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.
WARNING - Do not use extraction
machines for dry vacuuming
The vacuum motor on your extractor is not
protected by a dry dust filter. You should only use
the vacuum in conjunction with the solution spray.
SOLUTION SYSTEM
The quick connector on the end of the cleaning tool
solution hose is connected to the machine,
completing the solution circuit from the solution tank
via the pump to the cleaning tool head. The female
connector incorporates a pull-back release ring
which houses steel ball bearings. These should be
lubricated regularly otherwise connection may
become difficult. The cleaning tool head is made
from high impact thermoplastic. Do not attempt to
use the cleaning tool on hard surfaces or concrete,
which may result in damage to the plastic head.
•
Always check that the filters in the solution
tank are in good condition. Remember that
the filters are there to protect the pump from
dirt and fibres and it is a lot easier and cheaper
to replace the filter than it is the pump!
•
Always use a clean bucket when you
replenish your solution tank. This help will
prevent soil and sediment from entering the
cleaning solution tank and pump system!
