- Remove the oil filler cap and wipe the dipstick clean.
- Insert the dipstick into the filler neck, but do not screw it in.
- The oil level must show between the minimum and maximum marks on the dipstick.

3.3 Stopping
LE/LF/LT
1. Move switch (4-Fig. 5.6) to position 0 or push switch (S1-Fig. 2.26) to position 0.
2. Close air outlet valve (AV-Figs. 1.4/1.6).
3. Switch off the voltage.
If a compressor with pressure switch with pressure release valve stops during operation through a power
failure, the pressure from the air receiver must be released by moving the switch on top of the air pressure
switch to 0 to prevent the compressor from restarting against back-pressure when the power becomes live
again.
LE/LF/LT Trolley
1. Set pilot valve (RV-Fig. 1.16) in the unload position by turning the red handle 90 degrees (see section
5.6).
2. On LE/LF/LT Trolley with electrical motor, move switch (4-Fig. 5.6) to position 0 or push switch
(S1-Fig. 2.26) to position 0.
If the compressor is not required for immediate further use, switch off the voltage at the main circuit
breaker and unplug.
3. On LE/LF/LT Trolley with petrol engine:
Stop the engine, consult the engine "Owner's manual".
4. Close the air outlet valves (AV1/2-Fig. 1.12 and 1.16). Depressurize and disconnect the air lines from
the outlet valves.
