6 Before use 6.1 Check the tool NOTE Read the operating instructions before the tool is operated for the first time. Check that no cartridge strip is loaded in the tool. If a cartridge strip is present in the tool, use the cycling grip to cycle the tool several times until the cartridge strip projects from the tool at the cartridge strip exit and it can be pulled out and removed from the tool. Check all external parts of the tool for damage and check that all controls operate faultlessly.
7.2.3 Inserting the cartridge strip 4 Push the cartridge strip into the cartridge strip guideway on the side of the tool, as far as it will go. 7.2.4 Driving fasteners with the magazine tool 5 en 1. 2. 3. Press the tool against the working surface at right angles. Drive the fastener by pulling the trigger. Prepare the tool for driving the next fastener by pushing the cycling grip back toward the rear of the tool and then forward to its original position. 7.2.
7.5.3 Inserting the cartridge strip 4 Push the cartridge strip into the cartridge strip guideway on the side of the tool, as far as it will go. 7.5.4 Driving fasteners with the single-fastener tool 1. 2. 3. Press the tool against the working surface at right angles. Drive the fastener by pulling the trigger. Prepare the tool for driving the next fastener by pushing the cycling grip back toward the rear of the tool and then forward to its original position. 7.5.
7.7.3 Driving fasteners using the grating fastener guide 16 1. en 2. 3. 4. 5. Press the tool against the working surface at right angles. Drive the fastener by pulling the trigger. If possible, check the depth of penetration by checking fastener stand-off. If using a flange, screw the retaining flange on with torque of 5 to 8 Nm. Prepare the tool for driving the next fastener by pushing the cycling grip back toward the rear of the tool and then forward to its original position. 7.7.
NOTE Do not use a spray or steam/water jet system for cleaning! Never operate the tool when the ventilation slots are blocked. Do not permit foreign objects to enter the interior of the tool. 1. 2. 3. 8.2 Maintenance Check all external parts of the tool for damage at regular intervals and check that all controls operate faultlessly.

Fault Possible cause Remedy Fastener penetrates too deeply (inadequate fastener stand-off). The fastener missed the steel beam. Mark the position of the beam. Drive another fastener into the beam. Check to ensure that the sheet rests tightly against the supporting material. The wrong piston has been fitted. Check that the right piston / fastener combination is used. The piston is worn. Change the piston and piston stopper. Fastener driven into the rib of the beam.
en Fault Possible cause Remedy The tool remains compressed (doesn’t extend when pressure is released). The cartridge strip has jammed, the tool has overheated. The tool can’t be fired. The tool wasn’t cycled correctly, the cycling grip is not in the starting position. The trigger is pulled before the tool is pressed fully against the working surface. Fastener transport malfunctions Please refer to the fault: “Cartridge strip can’t be removed”.
Fault Possible cause Remedy The piston can’t be fitted. Pull the pusher forward until it engages. The piston guide can’t be fitted. The tip of the pusher is projecting into the piston guide, preventing movement of the piston. The lever is in the closed position. Stiff cycling action. The piston guide is incorrectly positioned. The tool needs to be cleaned. Insert the piston guide in the correct position. Clean the tool. See section: 8.2.2 Cleaning the piston guide 18 19 20 21 Open the lever.
