User manual RYOBI PCN-4550

[. . . ] Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. This enable better control of the power tool in unexpected situations. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. [. . . ] In accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from intended could result in a hazardous situation. Ensure the switch is in the off position before inserting battery pack. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws or other small metal objects that can make a connection from one terminal to another. Under abusive conditions, liquid may be ejected from the battery, avoid contact. Remember that a careless fraction of a second is sufficient to inflict serious injury. WARNING Always wear safety goggles or safety glasses with side shields when operating tools. Failure to do so could result in objects being thrown into your eyes, resulting in possible serious injury. WARNING Do not use any attachments or accessories not recommended by the manufacturer of this tool. The use of attachments or accessories not recommended can result in serious personal injury. Experiment in an out-of-the-way area to find the best speed to use to deliver the caulk bead you want. If filling a crack, insert the spout into the crack, if possible; otherwise, run the caulk gun along the surface. Squeeze the trigger on the caulk gun, allowing the caulk to extrude from the tube tip. note: If the bead of caulk is too narrow , re-cut the nozzle to provide a larger opening. However, it is better to apply a thin bead of caulk and add a little more if necessary than to apply too much and attempt to remove the excess. Carefully move the caulk gun at an even pace along the gap to be filled as you continue to depress the switch trigger. Make sure the caulk comes in full contact with both application surfaces. If necessary, use your finger to gently press the caulk into a corner or crack. Note: The best fill is usually achieved by pushing the caulk out into the gap in a forward motion. However, in some cases (particularly where the side materials are rough or uneven), a pulling motion may work better as the cartridge will be less likely to get snagged along the joint. The motor will shut off automatically when a caulk tube becomes empty. [. . . ] To work properly, the plunger rod of the tool must remain clean and free of all caulk and adhesive material. If material does get on the plunger rod mechanism, clean the material off according to the directions of the caulk or adhesive manufacturer. When the tool is shut off by the electronic overload protection system, always wait for 3 to 5 seconds before depressing the trigger for restart. Frequently depressing and releasing the trigger under these circumstances may cause interior damage to the caulk gun. [. . . ]
