General safety warnings

WARNING: Read all safety warnings and all instructions. Failure to follow the warnings and in- structions may result in electric shock, fire, serious injury and/or death.

• Use the gas tool and accessories in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the gas tool for operations different from those intended could result in a hazardous situation.

• Stay alert, watch what you are doing and use common sense when operating the gas tool. Do not use the gas tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating the gas tool may result in serious personal injury.

• The risks to others shall be assessed by the operator.

• Use CE-marked eye protection with front and side protection against flying objects when han-dling, operating, and servicing the gas tool.

• Use CE-marked ear protection near or at the job site to prevent hearing damage. Unprotected exposure to high noise levels can cause perma-nent, disabling, hearing loss and other problems such as tinnitus (ringing, buzzing, whistling or humming in the ears). Appropriate controls to re-duce the risk may include actions such as damping materials to prevent workpieces from “ringing”.

• It is recommended to wear CE-marked head protection at the job site.

• It is employer’s responsibility to enforce gas tool users and all other nearby personnel at the job site to wear personal protective equipment such as eye protection, dust mask, non-skid safety shoes, hard hat and/or hearing protection.

• Dress properly. Do not wear loose clothing or jewel-lery. Keep your hair, clothing and gloves away from moving parts to avoid serious injuries. Only wear gloves that provide adequate feel and safe control of trigger and any adjusting devices. Wear warm clothing when working in cold conditions, to keep your hands warm and dry.

• Do not overreach. Keep proper footing and balance at all times. This enables better control of the gas tool in unexpected situations.

• Prevent unintentional starting. Do not carry the gas tool with your finger on the trigger.

• Respect the gas tool as a working implement.

• Do not engage in horseplay.

• Remove any adjusting keys or wrenches before using the gas tool. A wrench or a key left attached to a mov-ing part of the gas tool may result in personal injury.

• The gas tool is not designed to be used in explosive atmosphere such as in the presence of flammable liquids, gases or dust. The design of the gas tool will generate sparks and the exhaust will also cause possible danger to ignite highly flammable fuel or gas. Do not use the gas tool in this kind of environ-ment. Do not smoke while using or handling the gas tool and/or fuel cell.

• Ensure combustible materials are not exposed to hot exhaust gases.

• Handle the gas tool with care, as it can get hot, affecting grip and control.

• Keep work area clean and well lit. Cluttered or dark areas invite to accidents.

• The gas tool needs to be used in well ventilated areas. Do not inhale the exhaust, fume or gas as it is potentially dangerous to the human body.

• Under abusive conditions, liquid may be ejected from the battery and/or fuel cell; avoid contact.
  If contact accidentally occurs, flush with water. If liquid get in contact with eyes, additionally seek medical help. Liquid ejected from the battery and/or fuel cell may cause irritation or burns.

• A small release of gas might be generated by regu-lar operations.

• Do not use the gas tool if it is not in proper working condition.

• Inspect the gas tool before operating to determine that the gas tool is in proper working order. Check for misalignment or binding of moving parts and any other condition that may affect the operation. Do not operate if any of the above mentioned conditions occur as it can cause malfunction.

• When leaving the gas tool in resting position use the belt/raftering hook or place it on the tool front or side. Do not leave it resting with the nose piece pointing towards the operator or anyone nearby.

• Do not store the gas tool in temperatures above 49°C(120°F). High temperature may result in explo-sion or fire and the release of flammable gas. When not in use, keep the gas tool from high temperature sources or direct sun light.

• Do not expose the gas tool to rain or wet conditions. Water entering the gas tool will increase the risk of electric shock and/or tool breakdown.

• Always assume that the gas tool contains fasteners. Careless handling of the gas tool can result in unex-pected firing of fasteners and personal injury.

• Do not point the gas tool towards yourself or anyone nearby whether it contains fasteners or not. Unex-pected actuation will discharge the fastener causing an injury.

• Do not force the gas tool. Use the correct gas tool for your application as it will do the job better and safer at the rate for which it was designed.

• Do not actuate the gas tool unless it is placed firmly against the workpiece. If the gas tool is not in contact with the workpiece, the fastener may be deflected away from your target.

• Do not drive the gas tool over materials that is too hard or too soft. Hard material can ricochet fastener and hurt people, soft material may be penetrated easily and cause the fastener to fly freely.

• Do not drive fasteners into other fasteners.

• Use extra caution when driving fasteners into exist-ing walls or other blind areas to prevent contact with hidden objects or persons on other side (e.g., wires, pipes, electrical cables.)

• After driving a fastener, the gas tool may spring back (“recoil”) causing it to move away from the work surface. To reduce risk of injury always man-age recoil by:

  • always maintaining control of tool and be ready to counteract normal or sudden movements such as recoil.
  • allowing recoil to move tool away from work surface.
  • not resisting recoil so that the gas tool will be forced back into the work surface.
  • keeping face and body parts away from tool.

• When working close to an edge of a workpiece
  or at steep angles use care to minimize chipping, splitting, splintering, or free flight or ricochet of fasteners, which may cause injury.

• Do not use this gas tool for fastening electrical ca-bles. It is not designed for electric cable installation and may damage the insulation of electric cables thereby causing electric shock or fire hazards. Fur-thermore the gas tool is not insulated from coming into contact with electric power.

• Do not use the gas tool to perform other jobs than the designated function. Especially do not use it as a hammer. Impact on the gas tool will increase the risk of cracked tool body and accidental discharge of fastener.

• Do not use the gas tool if safety warning label(s) are missing or damaged.

• Do not remove, tamper with, or otherwise cause tool operating controls to become inoperable. Do not operate tool if any portion of the tool operating controls is inoperable, disconnected, altered, or not working properly.

• Disconnect battery and fuel cell from the gas tool before making any adjustments, changing accesso-ries or storing the gas tool. Such preventive safety measures reduce the risk of activating the gas tool accidentally.

• The gas tool should not be modified unless authorized in the manual or approved in writing by Kyocera Unimerco Fastening. Fail to comply can lead to dangerous situations or injurys.

• Keep hands and body away from fastener discharge area of the gas tool.

• Do not operate the gas tool with batteries other than the specifically designated battery packs delievered with this gas tool.

• Use only fasteners designated in the technical specifications delievered together with this manual.

• Be careful when handling fasteners, they may have sharp edges and sharp points.

• Use only accessories made or recommended by the tool manufacturer, or accessories that perform equivalently to those recommended by Kyocera Unimerco Fastening.

• Load the fastener after loading the battery and fuel cell to prevent unexpected fastener firing.

• Disconnect the battery (Fig. A) and fuel cell (Fig. B) if the fastener jams in the gas tool. While removing a jammed fastener, the nailer may be accidentally activated if the battery and/or fuel cell is plugged in.

• Use caution while removing a jammed fastener. The mechanism may be under compression and the fas-tener may be forcefully discharged while attempting to free a jammed condition.

• Remove the fuel cell and battery when

  • Not in use;
  • Performing any maintenance or repairs;
  • Clearing a jam;
  • Elevating, lowering or otherwise moving the gas tool to a new location;
  • The gas tool is outside of the operator’s supervi-sion or control
