DETAILED SAFETY REGULATIONS

PRECAUTIONS FOR USING HAMMER DRILL

Caution: Unplug the power cord from the mains socket before commencing any activities related to adjustment, repair or maintenance.

- During hammer operation use protective glasses or goggles, ear protection and protective helmet (when there is danger of falling objects). Use of protection half-mask and anti-slip boots is recommended. Use dust extraction systems whenever required by the nature of the work performed.

Prior to operation ensure the drill chuck of the hammer is properly fixed in its place. ●

• During operation working tool may get loosened due to vibrations. Check carefully how the working tool is fixed prior to operation. Unwanted slack may cause tool damage or accident during operation.
• If the hammer is to be operated at low temperature or after long storage, allow the hammer to operate for few minutes without load, for its internal elements get properly lubricated.
• When operating the hammer held high, stand firmly on the ground and ensure there are no bystanders below.

Always hold the hammer with both hands, use additional handle. ●

- Do not touch moving parts of the hammer. Do not stop rotating spindle of the hammer with your hands. Such behaviour can cause hand injury.

Do not direct operating hammer at other persons or at yourself. ●

• When operating the hammer, hold it by insulated parts to avoid electric shock in case of damaging live electrical wire.
• Do not allow any dust to get inside the hammer. Use mineral soap and damp cloth to clean hammer surface. Do not use petrol or other cleaning agents that could damage plastic parts.
• When use of extension cord is necessary always remember to use appropriate one (up to 15 m, section 1.5 mm ² ; between 15 and 40 m, section 2.5 mm ² ). Extension cord should be unwound whole.
• Do not use three jaw drill chuck when the hammer drill is set to impact drilling or chiselling mode. This chuck is designed only for regular drilling in wood or steel.

CAUTION! This device is designed to operate indoors.

The design is assumed to be safe, protection measures and additional safety systems are used, nevertheless there is always a small risk of operational injuries.

CONSTRUCTION AND USE

Hammer drill is a hand-operated power tool with insulation class II. The tool is driven by single-phase commutator motor. Hammer drill can be used for drilling holes in working mode with impact, digging channels, or surface processing of materials such as concrete, stone, brick etc. 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.

INSTALLATION AND REPLACEMENT OF WORKING TOOLS

Hammer drill is designed to operate with working tools with SDS-MAX shanks.

Prior to starting operation clean the hammer drill and working tools. Use grease and apply thin layer onto shank of the working tool. It will improve tool durability.

Disconnect the power tool from power supply.

Put the hammer against work bench. ●

• Hold the fixing sleeve (2) of the SDS chuck (1) and pull it to the back, overcoming the spring resistance.
• Insert working tool shank into the chuck and slide it to mechanical stop (it may be necessary to turn the working tool so it can reach appropriate position) (fig. A).
• Release the fixing sleeve (2), it will finally fix the tool.
• Working tool is properly seated if it cannot be removed without pulling off the fixing sleeve.
• If the sleeve does not return to its default position, remove the working tool and repeat the whole operation.

High efficiency of the hammer drill 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 fixing sleeve (2) to the back and hold.
• Remove the working tool with your second hand by pulling it to the front.

OVERLOAD CLUTCH

Hammer drill is equipped with factory set overload clutch. Spindle of the hammer drill stops immediately after working tool jams, which might overload the power tool.

SWITCHING ON / SWITCHING OFF

The mains voltage must match the voltage on the rating plate of the hammer drill.

Switching on - press the switch button (5) and hold in this position (fig. B).

Switching off – release pressure on the switch (5).

GRAPHITE

Hammer drill is equipped with 2-function switch of the working mode (3). Depending on its setting, an impact drilling or chiselling is possible. Impact drilling and chiselling require to slightly press the hammer drill. Too great pressure would cause unnecessary, excessive load of the motor. Check technical condition of the working tools regularly. Sharpen or replace working tools when needed.

Impact drilling - set the switch (3) to position marked with the drill and hammer symbol (fig. C).

Chiselling - set the switch (3) to position marked with hammer symbol.

Do not try to change position of the working mode switch when the hammer drill motor is operating. Such action may cause serious damage of the hammer drill.

VOLTAGE INDICATOR LAMP

When the rotary hammer drill is connected to power supply socket, the voltage indicator lamp lights up (6).

IMPACT DRILLING

• Choose appropriate mode of operation, impact drilling in this case.
• Insert appropriate drill with SDS-MAX shank into the chuck (1).
• To get the best results use high quality drills with sintered carbide inserts.
  Press the drill against processed material. ●

- Switch on the hammer drill, the hammer mechanism should operate smoothly and the tool should not bounce on the processed material surface.

Unplug the power cord from the mains socket before commencing any activities related to installation, adjustment, repair or maintenance.

- Always keep the hammer drill clean.

Never use any caustic agent for cleaning plastic parts of the hammer drill. ●

- After operation use compressed air to blow through the hammer drill to remove dust deposit, especially to keep ventilation slots pervious.

- It is necessary to regularly check technical condition of carbon brushes of the motor (dirty or worn out brushes can cause excessive sparking and loss of spindle speed of the hammer drill).

GEAR GREASING

It is recommended to check grease in the gear every 50 hours of hammer drill operation and fill up grease according to needs.

• Loosen the lid (4) for greasing inlet by turning it left (fig. D).
• Fill up grease.
• Fix the lid (4) and turn it right (do not twist it too tightly to avoid thread damage).

Do not apply too much grease.

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.

Entrust replacement of carbon brushes only to a qualified person. Only original parts should be used.

ADDITIONAL HINTS FOR USING HAMMER DRILL

To achieve the best possible efficiency when working on concrete, apply moderate (not excessive) pressure on the hammer drill. Excessive pressure leads to efficiency loss. Hammer drill filled with solid grease requires some time to heat up, depending on the ambient temperature. New hammer drill requires some time to work before it achieves full working efficiency. As mentioned above, high efficiency of operation can be achieved by using sharp tools and taking care of ventilation holes to be pervious.

All faults should be repaired by service workshop authorized by the manufacturer.
