You can insert power cord plug into mains socket only when you are absolutely sure that the hammer is switched off with the switch button. When you finish working with the demolition hammer, remove the plug from mains socket immediately.
During operation of the demolition hammer its power cord must always be placed behind the power tool. Do not pull the hammer by the power cord.
When working with the demolition hammer, hold it with both hands and keep your body in firm position.
Remove the plug from mains socket when the hammer is not in use or before starting any tasks related to working tool replacement, repair, maintenance or adjustment.
Do not allow persons under 16 years old to use the demolition hammer.
Do not allow children to have access to the hammer.
Use only original parts when repairing the demolition hammer.
Use external dust extraction system whenever possible.
Always use dust-mask when operating the demolition hammer.

PRIOR TO OPERATION

Bear in mind that you can spot hidden electrical cables, gas and water pipes. First check the area where you plan to work with demolition hammer using voltage and metal detector.
Use appropriate voltage. Mains voltage should match the voltage on the rating plate of the power tool. Demolition hammer is designed to work with supply voltage 230 V.

CAUTION! This device is designed to operate indoors. The design is assumed to be safe, protection measures and additional safety systems are used, ne-vertheless there is always a small risk of operational injuries.

CONSTRUCTION AND USE

Demolition hammer is a hand-operated power tool with insulation class II. The tool is driven by single-phase commutator motor with rotational speed reduced with gear transmission. Power tools of this type are widely used for works in concrete, brick and similar materials. Range of use covers repair and building works, and any work from the range of individual, amateur activities (tinkering).
Use the power tool according to the manufacturer’s instructions only.

PREPARATION FOR OPERATION

INSTALLATION OF ADDITIONAL HANDLE
Due to safety issues, always use an additional handle (4) when operating the demolition hammer. It can be fixed in any position from the range of 360O. Disconnect the power tool from the power supply.

Slide the additional handle (4) collar over cylindrical part of the demolition hammer body.
Fix the screw that joins two parts of the handle with holders.
Recess in the screw head should match protrusion on the handle flat bar (protection against turning).
Join the clamping wheel of the handle (3) and the screw.
Turn the handle for the position that is most comfortable for the work performed.
Tighten the clamping knob to finally clamp the handle (4).

DUST COVER INSTALLATION
Anti-dust cover is a rubber casting of appropriate shape. Place it on the tool holder to catch dust when operating the demolition hammer. Fix it to the tool holder before starting operation.
INSTALLATION AND REPLACEMENT OF WORKING TOOLS
Demolition hammer is designed to operate with working tools with 30 mm hexagonal shanks. Prior to starting operation clean the demolition hammer and working tools. Apply thin layer of grease onto shank of the working tool.
Disconnect the power tool from power supply

Pull the tool holder bolt (2) against the spring and turn it by 1800 to position it properly, so you can insert working tool into the tool holder (1) (fig. A).
Insert working tool shank into tool holder (1) through anti-dust cover, and slide it to mechanical stop (it may be necessary to turn the working tool so it can reach appropriate position).
Pull the tool holder bolt (2) again and turn it by 1800 to lock the working tool in the tool holder (make sure the bolt is in correct position – secured).
Working tool is properly seated if it cannot be removed from the tool holder without pulling off and turning the tool holder bolt.
If the working tool is not appropriately secured, remove it from the holder and repeat the whole operation.

High efficiency of the demolition hammer operation can be achieved by using sharp and undamaged working tools.
DEINSTALLATION OF WORKING TOOL
Just after the operation is finished, the working tool may be hot. Avoid direct contact and use appropriate protective gloves. Clean the working tool after removal.
Disconnect the power tool from power supply

Pull the tool holder bolt (2) against the spring and turn it by 1800 (fig. A).
Remove the working tool with your second hand by pulling it to the front.

OPERATION / SETTINGS

SWITCHING ON / SWITCHING OFF
The mains voltage must match the voltage on the rating plate of the demolition hammer.

Switching on – Press the switch button (5) and hold in this position.
Switching off – release pressure on the switch (5).
Locking the switch (continuous operation)
Switching on

Press the switch button (5) and hold in this position.
Press the switch lock button (6) (fig. B).
Release pressure on the switch button (5).

Switching off

Press and release the switch button (5).

Do not use the demolition hammer when the ON/OFF switch is broken.
HAMMER OPERATION, DEMOLITION
Hold the hammer firmly with both hands and switch it on. To achieve the best possible efficiency during operation, apply stable and moderate (not excessive) pressure on the demolition hammer (excessive pressure would lead to efficiency loss). The hammer is factory lubricated and is ready for operation. Demolition hammer filled with solid grease requires some time to heat up, depending on the surrounding temperature. New demolition hammer requires some time to work before it achieves full working efficiency. If the demolition hammer is not used for a long time, or operates in low temperature, allow the hammer to work with no load for 3-5 minutes.
As mentioned above, high efficiency of operation can be achieved by using sharp tools and taking care of ventilation holes to be pervious.
During operation small quantities of grease may come up from between the working tool and tool holder. This is normal and when you intend to operate the hammer in a closed space it is recommended to cover area close to the working place.

OPERATION AND MAINTENANCE

Unplug the power cord from the mains socket before commencing any activities related to installation, adjustment, repair, maintenance or when any malfunction is observed.
Always keep the demolition hammer clean.

Never use any caustic agents for cleaning plastic parts of the demolition hammer.
After operation use compressed air to blow through the demolition hammer to remove dust deposit, especially to keep ventilation holes (7) in the motor cover (fig. D) pervious.
It is necessary to regularly check technical condition of carbon brushes of the motor (dirty or overly used brushes may cause excessive sparking and loss of rotational speed of the demolition hammer spindle).

GEAR GREASING
It is recommended to check grease in the gear every 60 hours of the demolition hammer operation and filling up or change of grease according to needs.

Unscrew the fixing screws and remove the lid (9) of greasing inlet (fig. C).
Remove used grease with cloth.
Fill with new grease (approximately 30 g).
Install lid (9).

Do not apply more grease than approx. 30 g. Otherwise, the power tool will not work properly. After the supplied grease ends, use another available grease resistant to high temperature.

REPLACEMENT OF CARBON BRUSHES
Replace immediately worn out (shorter than 5 mm), burnt or cracked motor carbon brushes. Always replace both brushes at a time.

Unscrew screws that fix the brush covers (8) (fig. D).
Unscrew brush caps.
Remove used brushes.
Remove any carbon dust with compressed air.
Insert new carbon brushes. Brushes should easily move into brush-holders.
Install brush caps.
Install brush covers (8).

After the brushes are replaced, start the demolition hammer with no load and wait until the brushes fit to the motor commutator. Entrust replacement of carbon brushes only to a qualified person. Only original parts should be used. All faults should be repaired by service workshop authorized by the manufacturer.
