4.3 Volume flow monitoring

20 m/s, an acoustic warning signal sounds for
safety reasons.
Possible causes and adjustments:
• Cause
- Adjustment
• Suction force regulator (1.8) set to a too
low value
- Adjust suction force regulator to a higher
value
• Rotary knob (1.2) not adjusted to the
connected hose diameter
- Adjust to correct hose diameter
• Suction hose blocked or twisted
- Remove blockage or twist
• Filter bag full
- Change filter bag
• Filter element dirty
- Change filter element
- Only when operating without a filter bag:
clean filter element
• Electronic monitoring system malfunctioning
- Call Festool customer service for
adjustment
4.4 Antistatic system (AS)
Friction in the suction hose causes electrostatic
charges which can result in unpleasant electric
shocks for the operator. In order to conduct
these static charges to earth, the extraction
units are provided with an antistatic system
as a standard feature. However, antistatic
hoses and accessories have to be used in this
case. The antistatic function will only work if
the plug is plugged into a totally earthed socket.
5 After finishing work
- Switch off the cleaner and pull the plug of the
mains lead out of the plug socket.
- Empty dirt tank.
- If noxious dusts have been extracted, the
vacuum cleaner and all accessories must be
completely cleaned (inside and outside) by
suction and wiping, before removal from the
contaminated area. Parts that cannot be
completely cleaned are to be packed for
transport in a plastic bag with an airtight seal.
- Deposit the appliance in a dry room, safe from
unauthorised use.
6 Temperature control
Always remove the mains plug from
the socket before carrying out any
maintenance work!
Any maintenance and repair work
requiring an opening of the motor
housing may only be carried out by an
authorised customer service work-
shop.
A safety test is to be carried out at least once
a year by the manufacturer or an instructed
person, e.g. for possible damage to the filter
and leaks in the appliance, and to ensure that
the control devices are functioning.
