Maintenance

Before starting any maintenance work, turn the system ON/OFF switch OFF
and secure against reconnection. If it is switched ON again unintentionally,
people who enter the unit are at risk from rotating parts.
Wait for the fan to come to a complete standstill before opening the inspection
doors. When the doors are opened, negative pressure may draw in loose
objects, which could destroy the fan or even cause a risk to life if items of
clothing (ties) are drawn in.
Initially recharge fan bearings with grease nipples with lithium soap grease after
approximately 50 hours run, and then every 2500 hours run.
Maintenance-free bearings are permanently lubricated and are identified
accordingly with labels.
Standard three-phase motors are maintenance-free.
In the case of special motors, follow the maintenance instructions of the motor
Please note
manufacturer.
Initially adjust the tension of V-belts after one hour in use. After this, checks at
regular intervals are required depending on the operating conditions, but should
be carried out at least every 4 months.
When changing the V-belt in multi groove drives, replace the entire belt set.
In the KG 40-100 Standard, the drive motor is attached to a sloping frame.
To adjust the tension of the V-belt, undo the locknut on the tensioning screw,
tighten the tensioning nut to the correct belt tension, and retighten the locknut.
Correct V-belt tension:
After tightening, the V-belt at the halfway point between the motor and fan shaft
must be able to be deflected by about 15 mm.
Check that the V-belt pulleys are aligned.
