Storage

The supplied GK-transmissions are provided with an internal preservation, ensuring a corrosion protection
for approx. 1 year at an adequate storage in closed and dry rooms.
If a transmission is to be stored for a longer time, the transmission has to be filled with the specified
transmission oil (see Chapter "Initial Operation / Maintenance" "Oil Grade").
At an input speed of 1000 to 1500 min-¹ the transmission is to be driven for approx. 2 minutes, so that all
transmission internal parts are wetted with oil.
If this is ensured, the oil can be drained off again.
We recommend repeating this procedure yearly!

Transport

The unit is only allowed to be lifted with soft ropes or belts, never with steel ropes or chains. During
transportation care must be taken to avoid shocks.

Removal of the corrosion protection

Only with a suitable cleaner the corrosion protection is to be removed from the connecting points before
installation into the vehicle. Never use benzene, solvents or other combustible substances for cleaning.
Only use non-toxic, non-combustible and commercially permissible cleaning agents.
Do not drain cleaners into the soil. Overflown cleaner is to be disposed of
adequately. Do not abrade with emery or scrape off! Avoid that cleaners get
in contact with rubber parts, the electrical connections of the accessories or
the motor ventilation!
Keep away cleaning agent from your skin, do not drink it or inhale its
vapours! Wear safety gloves and goggles! In case of skin contact rinse
immediately with a lot of water! If by mistake the cleaning agent was
swallowed, call medical aid immediately! Observe the regulations for the
prevention of accidents!
