preventative maintenance is carried out to ensure continued safe and
effective operation. Failure to carry out routine maintenance, in
particular the replacement of vacuum bags of the correct standard, could
render this equipment ineffective and the supplier can accept no
responsibility in this respect.
CAUTION: This equipment utilizes a EPA Micro filter module to collect
very small particles of dust. Do not operate the equipment without the full
filtration system fitted.
Do not use this equipment for the collection of hazardous or explosive dusts or biological agents; do not
use in a flammable or explosive atmosphere. This machine is for dry use only and must not be used or
stored in wet conditions.

•Take precautions to prevent spread of dust.
•Take care when disposing of waste material.
•Ask if you need advice.
•Keep the machine clean.
•Keep vacuum hoses and tubes clear.
•Regularly examine the power cable for damage.
•ALWAYS advise the supplier (in advance) if you are unable
to empty the equipment and are returning it containing waste.
DO NOT:
•Use steam cleaners or pressure washers to clean the machine.
•Immerse in water for cleaning.
•Attempt routine maintenance or cleaning unless first disconnected from power supply.
•Attempt to repair the machine if it is faulty – return to the supplier.

THE FOLLOWING MUST BE OBSERVED AT ALL TIMES
USERS MUST:
•familiarise themselves with instruction and information concerning use of the appliance, including the
method of removal and disposal of the material collected.
•make arrangements to ensure the vacuum bag can be changed and the fabric filter handled without
causing risk to operatives or others.
•After use ensure the outside of the appliance is decontaminated, the dust cap is secured, and the
machine wiped completely clean.
•remove all waste material from the equipment prior to its return to the supplier.
•treat accessories such as flexible hoses, brushes, tools etc. as contaminated after first use; they
cannot be returned to the supplier. When ultimately finished with these accessories should be
disposed of in accordance with the regulations for the waste material you are handling.
OPERATION:
Connect the vacuum to a power supply sufficient for
the model being used (see technical information
below); if using extension cables these should not
exceed 30m (approx. 100 feet) in length, and must be of
at least 2.5mm

If the vacuum power head is equipped with a dust cap
[CRQ Model] – remove this and fit the air diffuser (see

An On/Off switch is fitted to the
vacuum handle. Remove the inlet
cap on the waste collection drum, &
connect a vacuum hose, then
switch the vacuum on. A variety of
hose lengths and accessories are
available to aid cleaning – ask your
supplier.
Never continue to operate the vacuum cleaner when the suction hose is obstructed - you may cause the
motor to overheat or suffer damage.
If the vacuum bag requires replacement this should be undertaken by a competent person utilising
original Numatic parts. Bag change process: switch off the vacuum, disconnect the vacuum hose, fit the
dust cap, un-clip the toggle clamps, remove the power head, remove the cloth filter, remove the dust bag
from inside the drum and seal for disposal, clean cloth filter if
necessary. Fit new dust bag to inlet flange inside the drum, re-fit
cloth filter and the power head, secure the toggle clamps.
When you have finished using the machine vacuum it clean, switch
the vacuum off and disconnect it from the power supply, disconnect
the vac hose, re-fit the dust cap on the inlet of the waste drum, re-fit
the dust cap on the power head [CRQ Model only], and wipe the
machine completely clean.
The vacuum hose and accessories should be retained by the user (do not return to the supplier).
