▪ Switching on: Press ON/OFF switch (4).
▪ Switching off: Release ON/OFF switch (4).
Ccontinuous use:
▪ Switching on: Press ON/OFF switch (4) and in pressed
position lock it by button (5).
▪ Switching off: Press ON/OFF switch (4) once and release
it immediately.
WARNING: Before plugging in the tool, always check to see
that the trigger switch () actuates properly and returns to
OFF position when released.
OPERATION
Insert the plug into the socket.
▪ Apply the tool tip at 80–100 mm from the edge of the
material to be processed and press the trigger switch ().
▪ Start operating at 70°–80° to the surface and guide the tool
tip to the edge. Then change the angle to 90° and break the
processed mate¬rial.
▪ Operate the machine by utilizing its empty weight to
achieve optimum performance. Insufficient force shall cause
tool rebound. Too high pressure against the surface shall
decrease efficiency.
In some cases, it is necessary to punch the tool tip against
the crushing position forcibly in order to actuate the striking
motion. This is not due to mal¬function of the tool. It means
that the safeguard mechanism against no-load striking is
working.
WARNING: Sometimes the striking motion does not start
even when the motor rotates because the oil has become
thick. If the demolition hammer is operated at low ambient
temperature or after storage, let the machine run for five
minutes in order to warm up.
▪ Turn the tool at regular intervals to achieve uniform wear
and aid self-sharpening.

MAINTENANCE AND CARE

WARNING-Always unplug the machine before carrying out
work on it.
- When you notice a decrease in hammer output, take the
machine to an Official Service Centre.
- Tool inspection: Using a blunt cutting tool leads to less
efficient work and could damage the motor, therefore cutting
tools should be sharpened or replaced as soon as any wear
is noticed.
- Inspect the mounting screws: Regularly in-spect all
the mounting screws and ensure they are firmly tightened.
Should any screw be loose, tighten it immediately. Failure to
do so could put you at serious risk.
- Lubrication:
The power tool is delivered with the proper amount of
grease in its tank. Do not add grease to a newly pur-chased
demolition hammer. We recommend adding 40g of grease in
the tank only after  months after the initial operation of the
machine and in case it has been used continuously.
WARNING: Switch off and unplug the machine.
Assuming the demolition hammer is operated 3–4 hours
daily, the power tool can be used approximately 20 days
without replenishing oil, since the hammer is equipped with
an oil tank. When the level of oil in the oil gauge window (Fig.
) (on the bottom part of the power tool) drops below  mm
(inspection and measuring of oil level is performed with the
machine held upright), replenish oil immediately, otherwise
the power tool may be subjected to serious failure.
WARNING: Harmful or fatal if swallowed. Contains petroleum
distillate. If swallowed, do not induce vomit-ing. Call a doctor
immediately. Store away from heat or open flame. Keep away
from children.
Refill oil with the machine held upright. Prior to feeding oil,
remove the oil gauge using the provided hexagon bar wrench.
Take care not to lose the rubber sealing attached below the
oil gauge. After feeding oil, clamp the oil gauge securely.
Shell® Oil Co. ROTELLA 40 (engine oil) can also be used.
- Motor maintenance: Take the utmost care to ensure
that the motor winding is not damaged and does not become
damp with oil or water.
- Brush replacement: The brushes disconnect
automatically and should be replaced after 150-200 hours
use or when they are less than 10 mm long. Have them
replaced by an Official Service Centre.
- Clean the machine thoroughly after each use with a
blast of dry air.
- The vents of the machine should be kept clear at all
times.
- Check that the mains lead is in good condition. If it is not,
take it to an Official Service Centre to have it replaced.
- Use only Felisatti accessories and spares. The parts the
changing of which is not covered in this in-struction manual,
should be replaced in a Felisatti Official Service Centre (See
Warranty/Official Service Centre address leaflet).
