PRE-OPERATION
Before you start any operation make a visual inspection and check the fan for damage. In
case of damage operational safety is not assured, don’t use the fan for any operation.
MODELS WITH ELECTRIC DRIVE
Make sure there is a suitable power supply. Consider the high power consumption, espe-
cially at power-up due to the high performance of the fan.
For longer supply lines, pay attention to a sufficient cable cross-section of
the supply line.
MODELS WITH COMBUSTION ENGINE
Check oil level before you start the fan. Make sure the fan/engine is level:
1. Remove and clean oil fill plug/dipstick.
2. Insert oil fill plug/dipstick to the oil filler neck (without screwing it in) and remove it
again to check the oil level.
3. If the dipstick is dry, the oil level is too low. Pour oil slowly into the crankcase up to the
bottom edge of the filler neck. Do not overfill.
4. Replace oil fill plug/dipstick and tighten securely (hand-tight).
Do not overfill. In case of overfilling oil can be ejected from the engine brea-
ther while running and and get dispensed by the air stream.
Fan will be delivered without oil. Fill in oil before the initial operation.
The oil is an important factor for performance and durability of the engine. Use only 4-stro-
ke engine oil, which will achieve or exceed the requirements of API-service class SJ.
Recommended oils:
for summer operation (10°C bis 40°C):
SAE 30
year-round operation (-15°C bis 40°C):
SAE 10W-30
Capacity:
0,6l (HP 18) bzw. 0,9l (HP 21)
Refer to the engine manufacturers Owners Manual for additional information.
Required Fuel:
Gasoline (RON 91 or higher)
max. 10% by volume of ethanol
Fill the tank only to bottom edge of filler neck to provide space for fuel expansion. Do not
overfill the tank.
Gasoline is extremely flammable and explosive.
Stop the engine fur refueling. Pay attention to sparks, flames etc.
Refuel only outdoors. Wipe any spillage from engine, fan and
ground.
