ELECTRICAL INFORMATION
This appliance has been designed for dry vacuum cleaning only and must
not be used to pick up any liquids.
Kerstar declines any liability should this or any of the following measures not be observed.
Cable & Plug
This Vacuum Cleaner is an earthed appliance and has 10 metres of 3-core flex with a moulded on
impact resistant 13amp 3-pin plug (to BS 1363A). The fuse fitted (ASTA Approved) is rated at
13amps. Only 13amps fuses must be used. (Not applicable to 110V models – these are fitted with a
yellow 16amp 3-pin plug suitable for 110V).
Should the moulded on plug be damaged please follow this procedure:
Switch off supply at socket, remove damaged plug from socket, cut plug off from flex.
Make sure the damaged plug is disposed of immediately so as there is no chance of the damaged
plug being used.
Fitting a Replacement Plug
Use only a 13amp (approved) plug. To fit proceed as follows:
1) Ensure that the lengths of wire to be fitted inside the plug have
been cut to the correct length and the end correctly prepared. When
preparing the cable ends take care not to damage the out sheath, or
the insulation surrounding the inner conductors.
2) Connect the blue (NEUTRAL) wire to the terminal in the plug which
is marked with the letter “N” or coloured black.
3) Connect the brown (LIVE) wire to the terminal in the plug which is
marked with the letter “L” or coloured red.
4) Connect the green/yellow (EARTH) wire to the terminal in the plug which is marked with the
letter “E” or coloured green.
5) Tighten all screws. Ensure that all conductor strands have entered into the terminal posts and
that the mains lead is securely held in place by the cable clamp.
6) Ensure that the plug is fitted with a 13amp ASTA approved BS 1362 fuse. Replace the top cover
of the plug and secure.
Extension Cable
If using an extension cable at any time, always ensure that the insulation sheath is in good condition
and is not damaged in any way. Make sure that the socket is fitted to the extension cable correctly,
if in doubt have it checked by a qualified electrician. Always use the extension cable in accordance
with the manufacturers instructions.

UNPACKING YOUR VACUUM CLEANER
Unpack your cleaner and ensure that you have the spares and accessories as listed on the delivery
note.
Note
This range of dry industrial vacuum cleaners has a hose entry which will accept 32, 38 and 51mm
diameter hoses. Hoses and accessories are usually supplied to your order/requirement. Please check
you receive the accessories ordered.
Models on a caddy (KV18, 45, 65 & 110) are packed with the caddy handle removed for transport/
packing purposes. Refit the handle before use.
OPERATING INSTRUCTIONS
1. Connection to the Electricity Supply
Insert the mains plug into a suitable socket outlet. When you have finished cleaning unplug the
appliance. When coiling the mains cable make sure that any twists or knots in the cable come out
at the plug end. DO NOT coil cable from the plug end as all twists and knots remain in the cable
and considerably shorten its life.
2. Cleaner Controls
The following controls are provided:
a) The on/off switch is situated on the top of the motor head. To switch the appliance on firmly
press the part of the switch marked “1”. To switch off press the part of the switch marked “0”.
(Some models are fitted with one switch per motor)
3. Carrying and Storing
The assembled cleaner should only be moved by the carrying handle on top of the motor head. (Not
applicable to models on a caddy). Do not attempt to lift or drag the machine by the mains lead. The
cleaner must be stored indoors and in a dry environment.
4. Access to the Filtration System
a) To remove the motor head, unclip the clips. Ensure that the clips are hinged clear of the rim of
the motor head. Lift the motor head clear of the cannister.
b) To refit the motor head align the head so that the cable entry lies directly opposite the hose
entry on the cannister. Locate the clips over the rim of the motor head and firmly press down
the clips until they have locked into position.

FILTRATION SYSTEM
This vacuum cleaner is fitted with two stages of filtration. Both stages are on the negative pressure
(suction) side of the motor.
1) 1st Stage: K3 Paper Bag – KV18/1 and KV20/1
K4 Paper Bag – KV25/1, KV25/2 and KV30/1
K6 Paper Filter – KV20/2, KV30/2 and KV45/2
K7 Paper Filter – KV65/2 & 3 and KV110/2 & 3
K3 and K4 are disposable paper bags. They are fitted over the inlet inside the cannister and the dirt
and debris is collected inside the bag. When the paper bag is full or suction efficiency is impaired
the paper bag should be replaced. K3 and K4 paper bags are not designed to be emptied and should
not be reused.
K6 and K7 paper filters are used on larger vacuums in place of paper bags (which may burst when
being removed). Paper filters are fitted over the rim of the cannister and held in place with a strap.
Dirt and debris entering the cannister is collected in the bottom of the cannister. K6 and K7 paper
filter can be reused after the cannister has been emptied provided that it is not torn or holed.
2) 2nd Stage – Cloth Filter Assembly
A cloth/nylon type of filter material supported by a filter frame. A specially designed material for
use as a vacuum cleaner filter medium.
LOSS OF SUCTION / THERMAL CUTOUT SWITCH
If your cleaner loses suction power, first check that the hose and other accessories in use are not
blocked. Then check that the filtration system is not blocked. The filtration system can be serviced
as follows:
Paper Bags – If full, replace (if burst, empty out cannnister)
Paper Filters – Replace if torn or holed or shake dust off and reuse.
Cloth Filter Assembly – This filter will become contaminated with dust during normal use and/or
if the paper bag/paper filter is holed or burst. The dust must be removed either by brushing off or
by vacuuming with another vacuum cleaner. It is advisable to have a spare filter so that one filter
can be used in the machine and then the machine itself can be used to vacuum the dust off the
contaminated spare filter.
If any of the filters, paper bags or paper filters are damaged or holed, they must be replaced with
new items.
This vacuum cleaner is fitted with thermal cutout switch which automatically stops the motor if it
overheats. This may be caused by a blocked hose or wands, a full paper bag, or a blocked filter. If
your vacuum cleaner cuts out check for the above. The cutout switch will automatically reset itself
when the motor temperature drops.
