- If the generator often operates at high temperature or high load, the oil should be replaced every 25 operating hours.
- If the engine often runs in dusty or other harsh conditions, clean the air filter every 10 operating hours.
- If you missed the maintenance time, perform it as soon as possible to save the generator engine.
IMPORTANT!
Use oils designed for four-stroke cycle vehicle engines
SAE10W-30, SAE10W-40. Motor oils with other viscosity levels,
may be used only if the average air temperature in your region
does not exceed the limits of the temperature range, specified
in the table.
Upon oil level decrease it is necessary to add the required quantity in order to provide the correct generator opera-
tion. It is necessary to check the oil levels according to technical maintanance schedule.The detailed description of oil
filling and draining can be found in the full version of the manual.
Air filter cleaning is to be performed each 50 hours of the generator operation (every 10 hours in unusually dusty
conditions).

or CR7HSA(NGK) equivalent is recommended, for models KSB 30i S, KSB 40iE S - BPR6ES/BP6ES(NGK), F6RTC/
F6TC(TORCH) is recommended.
5. Measure the gap. It has to be within range 0.6-0.7 mm.
6. In case of repeated use, the spark plug has to be cleaned by means of a metal brush. After that – set the correct gap.
