If the belt slips for a second or two due to torque, this
is completely normal. Correct belt tension is
important for preventing early wear (slack belt) or
overload on the
(belt too tight).
To avoid down time, replace the drive belts at least
once a year before they become overworn.
The job of replacing a belt is very similar to that
described above for adjusting one bearing in mind
that:
1. for replacement, you need to undo screw "A" until
you can completely remove the belts from their
positions;
2. the tension of the new belts must be set using a
force F1 = F x 1,3;
3. after running the appliance for 60-120 minutes,
recheck the tension and set it to the value shown
in table in Fig 9.
Air filter
As the cleaning and replacing of the air filter depends
upon the conditions under which the appliance is
operating, check the filter once a fortnight. Clean or
replace the filter every 60 days.
Warning: Failing to clean or replace filters has a
significant effect on the efficiency of the system with:
• increased loss of load in the air circulation system
and reduced air flow;
• subsequent drop in system performance and in
comfort levels.
Precautions to take if mothballing the appliance
If the appliance is to be out of operation for a lengthy
period, some simple precautions should be taken:
• Disconnect the appliance from the mains leaving a
note to this effect;
• If the appliance has a filter, remove it and store it in
a sealed container.
• Every 30 days or so, rotate the motor and fan for a
few seconds to prevent any damage to the
bearings.

The "Checks and Tests" of the safety systems and
details of other maintenance work must be recorded
in an "Appliance Book" as per the above schedule.
The periods expressed are to be taken as days of
continuous appliance operation lasting 12 hours per
day. Periods of operation that are longer or shorter
than 12 hours per day count as fractions of scheduled
maintenance periods.
The "Checks and Tests" for safety systems and
the greasing of bearings fitted with grease nipples
must be carried out at least once a year even if the
appliance is not used much.
