Regular maintenance is limited to a visual inspection. Check the gearbox,
that there are no lubricant losses due to leaks. Relubrication is required
only if a greater amount of lubricant leaks out due to leakage losses.
Please contact to customer service of Systec for leakage losses.

Rotary modules with toothed belt gearbox
Maintenance interval
For rotary modules with toothed belt gearbox check the toothed belt
tension twice a year and, where appropriate, adjust it.
Measuring the ten-
sion
First, screw a side cover (1).
Then expose practicing a drawbar pull of the Newton meter in the mid-
dle of the toothed belt (5), and measure the deflection from the rest po-
sition.
1: Screws side cover
2: Screws motor
adapter
3: Clamping screws
4: Motor
5: Toothed belt
Fig. 32 Overview of a rotary module with toothed belt drive
Target value
When applying a force of 20N, the deflection should be 4-7 mm.
Retension
If the measured deflection deviates too much from the target value, a
readjustment of the toothed belt is required.
The adjustment of the timing belt is now carried out in three steps:
Step 1
Relax screws (2) of the motor adapter a bit.
Step 2
Tighten or loose clamping screw (3) until the target value is achieved.
