b. Pre-motor filter
3. Open the front cover.
4. Clean or change filter.
Please note:
The sponge filter material in the cleaner will became dusty over time. This is normal
and will not affect the performance of the filter. If the sponge filter is so dusty that
suction does not return to 100%, then we suggest that the filter be removed then
rinsed under the faucet and allowed to dry for 24 hours by airing not near the fire or
some high temperature objects before refitting into the vacuum. This should be done
once six months or when suction appears to be reduced obviously.
Important:
Please note that there is a safety switch inside the vacuum to prevent the unit from
being run with high vacuum rate. If the vacuum is too high ,the safety switch will be
turned on. In this case, it can minish the vacuum rate and protect the motor from
being broken.
Note:
The suction hole must be open, free of any obstructions at all times. Otherwise, the
motor will overheat and could become damaged.
Important:
All filters should be checked regularly for signs of damage, preferably after each
cleaning task. The filters must be replaced immediately if they become damaged.
Always disconnect the vacuum from the electrical outlet when checking the filters.
