General

WARNING! The user must only carry out the
!
maintenance and service work described in
this Operator's Manual. More extensive work
must be carried out by an authorized service
workshop.
The machine should be switched off with the
power cable disconnected from the outlet.
Wear personal protective equipment. See
instructions under the "Personal protective
equipment" heading. It is strongly advisable
that all operators use a dust mask/respirator
when changing dust bags or performing
maintenance on the machine.
The life span of the machine can be reduced and the risk of
accidents can increase if machine maintenance is not carried
out correctly and if service and/or repairs are not carried out
professionally. If you need further information please contact
your nearest service workshop.

Daily maintenance

• Check that the machine's safety equipment is
undamaged. See instructions in the section "Machine's
safety equipment".
• Check that the cord and extension cord are intact and in
good condition.
• Clean the outside of the machine.
• It is highly recommended that operators check dust levels
inside secondary filter housing on a daily basis. If when
inspected, it is found that there is dust building up inside
the secondary filter housing, it is recommended to remove
the primary filters and check for small holes or
perforations. Usually, small holes will begin to develop
around the stitching of the filter media. If small holes are
located, clean area around hole with either compressed
air or vacuum. Once area is clean, the hole can be
repaired with silicone sealant. If no small holes or
perforations are found, check rubber seals in the primary
filter housing assembly and make sure they are all intact.
Cleaning the primary filters
After every 10-20 minutes of operation, the primary filters will
need cleaning as dust will buildup on the inside of the filter
socks. An increase in residual dust on the ground behind the
grinder will be noticed.

MAINTENANCE

• Switch the machine to the off position.
Replacing primary filters
With consistent use, the primary filters should be replaced
approximately every 6 months. This will maintain good suction
levels and reduce incidence of holes developing in the filters.
• Release the two toggle latches and lift off the top unit.
• Tilt the entire silo unit backwards on it's rear wheels.
• Use the rear handle to support unit while laying down.
• Open the dust flap and reach the fastening nut through the
dust collection cone. Detach the sock filter assembly from
the agitator arm. Use a socket extension bar to reach in
and unscrew the agitor arm nyloc-nut.
• Raise the silo up and lift out the primary filter sock
assembly. Put the filter assembly upside down on a work
bench.
