the locking nut and remove the filter element.
Check the air pre-cleaner every 25 working hrs as follows:
-
Loosen the pre-cleaner carefully from its cap, remove
deposits from its element and wash it in warm water with a
non-foamy detergent.
-
Rinse the filter element with the water, press the water out
and dry it up. Put the cleaned element into the body,
tighten up the nut and fit the cap again. In case of heavy
fouling check up the element more frequently.
-
Check up the paper element every 10 working hours. If
fouled change it.
CAUTION! -
Never oil the element and never clean it with
paraffin or similar detergents.
Valves
Design of valves and especially of hydraulic tappets minimises
operating noises and removes any further valves adjustment.
Ignition
The electromagnetic ignition requires no adjustment. Spark
plugs, power cable and plug socket should be checked every
100 hrs. This check consists in cleaning of electrodes and
setting of the spark gap to 0,75 mm. Spark plugs should be
changed every 300 hrs.
Cleaning of
Engine
Clean the engine according to its actual impurity grade by
means of the pressure air. Clean the engine also after every
change of oil or air filter element. Check up also the bolts
fixing the engine to the chassis.
CAUTION! Any repairs of the engine should be done by an
authorised Kohler service only.
Electric
Installation
Protect all wires against contact with oil products. Keep all
elements clean and avoid any damage of wires - short circuit
risk. All connections must have clean and proper contact
surfaces to avoid intermediate resistance at a wrong contact
point. Check the electrolyte level and density in individual cells
of the battery. When charging keep all instructions of the
battery manufacturer.
