position when checking the oil level.
HOW TO USE THE HAMMER
1. After placing the tool in the base hole, press the ON-button. In some cases it is necessary to lift the machine
and lightly punch the tool against the ground to begin operation. This is not due to malfunction of the tool. It
means that the safe guard mechanism prevents the device from switching on without load.

2. By utilizing the weight of the machine and by firmly holding the hammer with both hands, one can
effectively control the subsequent recoil motion. Proceed at a moderate mark-rate, the use of too
much force will impair efficiency. Caution: Sometimes the tool does not begin the striking stroke even
when the motor rotates because the oil has become thick. If the tool is used at low temperatures it is
recommended to run it for five minutes in order to warm it up.
OIL REFILL
1. Prior to refilling oil, always disconnect the plug from the power supply. Since an oil chamber is built
inside the electric hammer, it can be used for approximately 20 days without supplying lubricating oil,
assuming that the hammer is used continuously 3~4 hours daily
2. Refill oil into the oil tank as described below before using this hammer.
a. Just before no oil is visible in the oil gauge window when the device is held upright.
b. Before refilling oil, use the provided wrench to remove the oil gauge. Be careful not to lose the
rubber packing attached below the oil gauge.
c. Check the oil level once daily, confirming that oil is filled.
d. After refilling oil, securely clamp the oil gauge.
As an optional accessory, oil for the electric hammer is sold separately. Recommended oil:
synthetic gearbox oil of reasonable quality.
REPLACING CARBON BRUSHES
When the device is operated carbon brushes wear out steadily. When the insulation tip integrated inside
the brush gets revealed and touches the commutator it will trip the engine automatically. When this hap-
pens, both brushes must be replaced with new brushes of the same type.
Attention! Before commencing carbon brush replacement make sure the device is switched off and the
power cord is unplugged.
