4.7 Fitting the vacuum skirt
• Unplug and lay the machine down with the handlebar
resting on the floor. Remove the brush or drive disc.
• Stretch and fit the rubber buffer around the brush guard
• The flexible section of the skirt has a special spring sewn
into the fabric. Fit this spring section into the groove in the
rubber buffer.
• The spring is a reasonably tight fit to prevent accidental
movement in use and therefore must be pulled onto the
buffer by stretching.
• With the skirt on the buffer it can be moved in its groove
to bring the hose connector to the rear, ensuring the base
moulding lies in the cut-out provided in the outer ring of
the skirt, enabling free movement when in use (Fig.5).
4.8 Fitting the vacuum unit
• Stand machine upright, and clamp the vacuum unit sup-
port bracket to the handle tube in the specified position.
(Refer to instructions supplied with the unit).
• Rest the vacuum unit on the support bracket with the
control switch to the rear, and engage the locking bar on
the back of the unit to secure it in position.
• Push the flexible hose on to the vacuum unit and skirt.
• Plug the electrical lead from the vacuum unit into the
socket situated on the left side of the handle moulding.
The machine is now ready for use. The switch controlling
the vacuum unit is located on the back of the unit. The
OFF position is marked O.
4.9 Using the vacuum unit
IMPORTANT - For maximum suction the sliding shutter on
the top of the unit must be closed.
• Dust collected by the unit is contained within the filter bag
located behind the front cover.
• To replace the filter bag, switch off vacuum unit, release
front cover catch and lift off cover.
• Remove and dispose of used bag. Fit new bag and repla-
ce front cover.
5 STORAGE
Always unplug and wipe down and dry the machine after
use.The machine should normally be stored with the handle
in the fully upright position.
Wrap supply cord around the handlebar and cable winder
ensuring that the plug is not trailing on the floor. Store the
machine in a dry indoor area only.
Never store the machine with a brush or drive disc fitted as
this causes distortion, and results in instability during opera-
tion.
6 MAINTENANCE
WARNING - Before undertaking maintenance operations or
adjustments switch off machine and unplug from the electri-
city supply.
The machine requires minimum maintenance apart from the
following checks by the operator.
• Supply cord - Regularly inspect sheath, plug and cord
anchorage for damage or loose connection.
• Solution tank - Check water flow, if restricted inspect
hoses and tubes for blockage or kinks. Dismantle control
valve to clean if necessary. Check switch interlock for cor-
rect operation.
• Vacuum unit - All dust bags must be changed regularly
and hoses and connectors checked for blockage to avoid
unsatisfactory results.
• Motor overload cut-out - All machines are fitted with an
automatic reset motor overload cut-out. The cut-out will
operate to protect the motor from overheating by swi-
tching the machine off when there is excessive
friction/resistance to the cleaning head on the floor. This is
usually caused by the stickiness of the pad or floor. Turn
the cleaning pad over or if both sides are dirty replace
with a clean pad. It is not possible to obtain a good finish
on the floor using a dirty pad. Should the cut-out operate
it will reset automatically when the motor has cooled suffi-
ciently, usually after 15 - 30 seconds.
IMPORTANT - Should the machine fail to operate contact
the supplier from whom you purchased the machine.
7 AFTER SALES SERVICE
Should you require after sales service please contact the
supplier from whom you purchased the machine, who will
arrange service. Repairs and servicing should only be per-
formed by trained staff. Improper repairs can cause consi-
derable dangers to the user.
