Spark plug
To guarantee a flawless mode of operation of the
engine, the distance between the electrodes of the
spark plug should be between 0.5 and 0.7
mm. If
the spark plug is dirty, carefully remove accumula-
tions of dirt with a wire brush (see Figure
10).

Exhaust pipe
Regularly perform maintenance on the exhaust pipe. Use a screwdriver to remove foreign matter and
impurities.
Lubricating the gearbox
Open the gearbox cover to lubricate the eccentric shaft. The eccentric shaft should be lubricated in
regular intervals.
Cylinder cooling fins
Regularly remove the dust from the cylinder cooling fins to ensure that the cylinder receives sufficient
cooling. This is especially important as the demolition hammer is air cooled and the cooling effect is
gravely affected by the condition of the cooling fins. Clogged cooling fins might cause the motor to
overheat and the device to take severe damage in the process.
Lubricating the cylinder
50
g of special lubricant need to be put into the cylinder after a total working time of about 50
hours.
Troubleshooting
