Safety Notes

General Power Tool Safety Warnings
WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fi re and/or serious injury. Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains operated(corded) power tool or battery-operated (cordless) power tool.
Work area safety
► Keep work area clean and well lit. Cluttered or dark areas invite accidents.
► Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
► Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety
► Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
► Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
► Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
► Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
► When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
► If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

Personal safety
► Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
► Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
► Prevent unintentional starting. Ensure the switch is in the off position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
► Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
► Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
► Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
► If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust related hazards.
► A good knowledge of power tools resulting from frequent use should not lead to overconfidence and neglect of power tool safety. One careless action in a split second can result in serious injury.
► ATTENTION! If an interruption occurs in the operation of the power tool due to a complete or partial loss of power or damage to the power control circuit, set the switch to the Off position, making sure it is not locked (if equipped). Unplug the mains plug or disconnect the removable battery. This prevents an uncontrolled restart.

Power tool use and care
► Do not force the power tool. correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
► Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
► Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
► Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
► Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may aff ect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
► Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
► Keep handles and gripping surfaces dry and clean and free of oil or grease. Slippery handles and gripping surfaces impede safe handling of the tool and prevent reliable control in unexpected situations.
► The appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities or lack of experience or knowledge, unless they are supervised or instructed to use the appliance by a person responsible for their safety.
► Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be per-formed. Use of the power tool for operations different from those intended could result in a hazardous situation.

Hammer Safety Warnings
► Wear ear protectors. Exposure to noise can cause hearing loss.
► Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
► Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
► Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage or may cause an electric shock.
► When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands.
► Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
► Always wait until the machine has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool.
► Make sure the accessory can rotate freely before turning on the power tool. When turning on the power tool with a jammed working tool, large reaction moments occur.
► Switch off the power tool if an accessory is jammed. Eliminate the cause of the attachment jam.
► For drilling without hammering in wood, metal, ceramics and plastics, as well as for screw driving, use tools without SDS-plus (for example drills with a cylindrical shank). These tools require a keyless chuck or toothed chuck.
► If the dust cap is damaged, it must be replaced immediately. The dust cap prevents dust generated during drilling from entering the chuck. When installing the accessory, be careful not to damage the dust cap.
► Dust from materials such as lead-based paints, certain types of wood, minerals and metals can harm your health and cause allergic reactions, respiratory problems and / or cancer. Leave the processing of asbestos- containing material only to specialists.
– If possible, use a dust extractor suitable for the material.
– Ventilate your work area well.
– It is recommended to use a respirator mask with a P2 filter. Observe the regulations in force in your country for the processed materials.
► Avoid dust accumulation in the workplace. Dust can be flammable.
► To save energy, only turn on the power tool when you intend to use it.

Since the product is constantly being improved, P.I.T. reserves the right to make changes to the specifications and product specifications specified here without prior notice.

Assembly

► Before any work on the machine itself, pull the mains plug.
Auxiliary Handle
► Operate your machine only with the auxiliary handle.
Changing the position of the auxiliary handle (segue A)
The auxiliary handle can be set to any position for a secure and low-fatigue working posture.
– Turn the bottom part of the auxiliary handle n counterclockwise direction and swivel the auxiliary handle to the desired position. Then retighten the bottom part of the auxiliary handle by turning in clockwise direction. Pay attention that the clamping band of the auxiliary handle is positioned in the groove on the housing as intended for.
Adjusting the Drilling Depth (see figure B)
The required drilling depth can be set with the depth stop.
– Lossen the bolt for the depth stop adjustment and insert the depth stop into the auxiliary handle. The knurled surface of the depth stop must face downward.
– Insert the SDS-plus drilling tool to the stop into the SDS-plus tool holder. Otherwise, the movability of the SD Splus drilling tool can lead to incorrect adjustment of the drilling depth.
– Pull out the depth stop until the distance between the tip of the drill bit and the tip of the depth stop corresponds with the desired drilling depth.
– Then tighten the bolt for the depth stop adjustment to fi x he depth stop.
Inserting SDS-plus Drilling Tools (see figure C)
The SDS-plus drill chuck allows for simple and convenient changing of drilling tools without the use of additional tools.
– Clean and lightly grease the shank end of the tool.
– Insert the tool in a twisting manner into the tool holder until it latches itself.
– Check the latching by pulling the tool.
As a requirement of the system, the SDS-plus drilling tool can move freely. This causes a certain radial run-out at no-load, which has no effect on the accuracy of the drill hole, as the drill bit centers itself upon drilling. Removing SDS-plus Drilling Tools (see figure D)
– Push back the locking sleeve and remove the tool.
Dust Extraction with the Dust Extraction Attachment

► Dust from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one’s health. Touching or breathing-in the dust can cause allergic reactions and/or lead to respiratory infections of the user or bystanders.
Certain dust, such as oak or beech dust, is considered carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the materials to be worked.

► Prevent dust accumulation at the workplace. Dust can easily ignite.
