and securely fastened.
▪ Prior to initial operation fill up the oil tank from the
tube of oil delivered with the machine. The built in
oil tank contains only a small amount of oil when
shipped from the factory.

WaRning: Switch off and unplug the ma-
chine prior to any procedure on the power tool.
1. Clean and then smear the tool shank with grease or
machine oil (Fig. 1).
2. Pull the tool retainer lever (3) toward yourself.
3. Rotate 180° clockwise the tool retainer lever (3) while
pulling it.
4. Next, insert the tool shank into the hexagonal tool
holder (1) on the front cover (2).
5. Clamp the tool by turning the tool retainer (3) by half
a turn in the opposite direction (Fig. 2).
To remove the bit, follow the above described proce-
dures in reverse order.

brief activation:
▪ Switching on: Press ON/OFF switch (4).
▪ Switching off: Release ON/OFF switch (4).
continuous 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, al-
ways check to see that the trigger switch (4) actuates
properly and returns to OFF position when released.

▪ 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
(4).
▪ 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 material.
▪ 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 malfunction 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.

VII - Maintenance
WaRning: Always ensure that the tool is
switched off and unplugged before attempting to perform
inspection or maintenance.
lUbricatiOn
The power tool is delivered with the proper amount of
grease in its tank. Do not add grease to a newly purchased
demolition hammer. We recommend adding 40g of oil in
the tank only after 3 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. 5) (on the bottom part of the power tool)
drops below 3 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 vomiting. 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
