Maintenance Instructions
Explosion hazard!
If the system is not entirely tight and sealed, the combustible gas mixture
may escape and result in an explosion hazard.
The device's tightness is checked and guaranteed by MOTORTECH after
production.
If the device is opened by the customer for installation or maintenance
purposes, the customer is responsible for restoring the system's leak
tightness.
If the customer cannot guarantee this, the device must not be opened and
must be replaced and returned to MOTORTECH to remedy any failures.
Observe the following maintenance instructions:
–
A visual inspection of the gas mixer must be carried out every time the engine is serviced
within the normal service intervals of your system. The visual inspection includes:
–
Checking the fuel ring for dirt. For having the VariFuel3 cleaned, contact your MOTOR-
TECH contact person (see
Customer Service Information
on page 41).
–
Checking the drive belt for signs of material fatigue (e.g. cracks)
–
MOTORTECH offers cleaning, for this purpose send in your gas mixer (see
Returning Equip-
ment for Repair / Inspection
on page 41).
–
All maintenance works which require opening the VariFuel3 (such as adjusting the fuel ring)
must only be carried out by personnel trained by MOTORTECH.
–
Dirty seals (e.g. flat gaskets, O-rings) can lead to leakage of the VariFuel3. When replacing
seals, only use clean seals from MOTORTECH (part of MOTORTECH repair kits).
–
Spare parts (e.g. drive belt, fuel ring) are available from MOTORTECH as repair kits. Always
use these repair kits, otherwise a proper functionality cannot be guaranteed.
–
If a safe repair cannot be carried out, since the gas tightness cannot be tested for example,
the device must be returned to MOTORTECH (see
Returning Equipment for Repair / Inspec-
tion
on page 41). If needed, a replacement or exchange device can be provided. For this
purpose, contact your MOTORTECH contact person (see
Customer Service Information
on
page 41).
