Fold the elasticated edge of the filter over the rim of the drum. Ensure that the filter covers the rim of
the drum all the way round. Ensure that the filter extends 2” (50mm) down the outside of the drum.
Fit the second Primary Filter inside the first and fold over the top of the drum as above.
If, whilst using the BIG MIKE in Dry Mode, you notice the Primary Filters aren’t in place, switch the
BIG MIKE off immediately. Refer to the section “If the BIG MIKE has been used without the Primary
Filters in place”.
6.1.3 Cleaning the Primary Filters
Clean the Primary Filters regularly and each time the drum is emptied. The Primary Filters can be
cleaned by shaking them. Remove the power unit from the top of the drum but leave the suction hose
in place to prevent dust escaping from the drum when you shake the filters clean.
Clean the uppermost Primary Filter by grasping the shaking-handle sewn onto the filter and shaking it
up and down to dislodge any dust and dirt on the underside.
Carefully remove and repeat for the second Primary Filter underneath.
To clean the Primary Filters more thoroughly, shake them clean as above and carefully remove them.
We recommend vacuuming the filter clean (separate Primary Filters can be purchased for this
purpose) or by beating them clean in a suitable area out of doors.
6.1.4 Checking the Primary Filters for Damage
Always inspect the Primary Filters for damage each time you clean them. Ensure they are free of holes
and show no signs of damage or wear.
If you’ve any doubt about the state of your Primary Filters, please replace them.
6.1.5 If the Primary Filters Get Wet
The Primary Filters are intended only for use in dry mode. Never use the Primary Filters in wet mode.
If the Primary Filters do get wet, clean them by shaking as described above. Carefully remove the
filters and allow them to naturally air dry. Vacuum or beat the filters clean and refit them before using
the BIG MIKE in dry mode again.
Warning
Always ensure the Primary Filters are dry before using in the BIG MIKE.
Fit the Primary Filters inside the
top of the drum.
