GETTING STARTED Please refer to the TOOL EXPLOSIVE ILLUSTRATION and the PARTS LIST in this manual in order to have a good understanding of the tool parts described. The descriptions of the tool parts appear in this manual are in italics with the parts position numbers corresponding to the tool explosive illustration. 1) This pneumatic powered tool should be used with a compressed air supply. It is recommended to use an air hose with a diameter bigger than 8mm. 2) Before connecting the tool to the compressed air supply, check that the compressed air pressure is within the specified range of between 0.5Mpa ~ 0.7Mpa. Once the air pressure has been confirmed, connect the air hose adaptor onto the tool air adaptor (#47). The air adaptor comes in different versions in different countries. Normally the tools are equipped with the correct version for your country as default, however, if the air adaptor you have received does is incorrect, please contact the tool distributor(s). 3) Change and use correct nosepiece (#1) according to the size of the rivet to be set. This tool is equipped with nosepieces 3.0/3.2mm, 4.0mm and 4.8/5.0mm (on the tool) in the kit. Follow the steps below to change the nosepiece (#1); a) Remove the air supply hose from air adaptor (#47). b) Use the wrench (in accessories pack) to remove the nosepiece (#1) from the tool as below; c) Select the correct nosepiece in the accessories pack and screw on to the tool, using the wrench to fix it firmly on the tool. 4) Install the mandrel release protector (in accessories pack) on the back of the tool.

TOOL OPERATION FOR SETTING BLIND RIVETS 1) After completing the start-up preparations, place the rivet mandrel into the nosepiece, and holding the tool to insert the rivet into the pre-drilled hole of the work piece that needs to be fastened. 2) Pull the tool trigger (#43) to set the blind rivet in its position on work piece. 3) After setting the rivet, tilt the tool to the front in order to release the mandrel from inside the tool or tilt back the tool and the mandrel will be released from the back of the tool into the mandrel release protector. While using the tool, be sure always with the mandrel release protector on the tool, in case a mandrel comes shooting out from the back and causes injuries. TOOL MAINTAINANCE In order to maintain optimum performance after several weeks of regular use, add a few drops of hydraulic oil on the inlet of the air adaptor (#47) of the tool in order to reduce the friction of the tool parts since the oil will be blown inside the tool when tool is in operation. After a period of use, the tool stroke may be reduced which indicated that the hydraulic oil in the pneumatic tool needs to be refilled or changed; 1) Remove the screw (#9) with a hexagon wrench:

2) Connect the air supply and to place a cloth over the hole where the screw (#9) was removed, then to pull the trigger (#43) and the oil will be forced out from the tool; 3) Screw the oil inject adaptor (in oil injector set in the accessories pack) into the hole where screw (#9) was removed; 4) Use the oil injector (in the accessories pack) to slowly inject the oil until full (approx. 15ml). Remove the injector and its adaptor, then clean off any excess oil on the tool and tightly screw the screw (#9) back into the tool; 5) Test the tool stroke. If the stroke is still not what it should be, some air could have entered the oil cylinder (#11) while refilling the oil in the tool. To release this extra air from the tool, connect the tool to the air supply, pull the tool trigger (#43) 6 or 7 times, then loosen the screw (#9), to let the extra air leak out and then tighten the screw (#9) again.

After extensive use, the tool may accumulate small metal chips from rivets within the nose assembly of the tool. This will compromise the tool’s efficiency; therefore, it is recommended that you clean or change the nose assembly parts periodically. 1) Use the wrench (in accessories pack) and a spanner provided by user; Included in accessories kit Provided by user Wrench hole 1 for compressed spring pedestal (#19); Wrench hole 2 for clamping sleeve (#3); Wrench hole 3 for nosepieces (#1); Wrench hole 4 for front sleeve (#2); 2) Remove the nosepiece (#1) on the tool using the wrench included in the kit; 3) Disassemble the front sleeve (#2):

4) Disassemble clamping sleeve (#3): 5) Take out the 3-jaw set (#4) from the clamping sleeve (#3), then remove the assembly pusher (#5) and the pusher spring (#6) from the tool. Once removed, inspect all parts for wear before cleaning and replacing them. Any damaged parts should be replaced at this time. 6) Re-assemble the cleaned or replacement parts. Put the pusher spring (#6) onto the assembly pusher (#5) and insert it back to the tool where assembly oil cylinder (#11) is located; 7) Place the 3-jaw set (#4) into the clamping sleeve (#3) and be sure that all 3 jaws are seated in the correct position;

8) Place the clamping sleeve (#3) with the 3-jaw set (#4) inside it onto the assembly pusher (#5) and ensure it is assembled firmly; 9) Replace the front sleeve (#2) and nosepiece (#1) on the tool; TROUBLE SHOOTING Problem Possible Causes Solutions Rivet mandrel does not break  3-jaw set worn off or damaged.  Hydraulic oil in tool not sufficient.  Air supply with low pressure.  Change 3-jaw set.  Refill hydraulic oil.  Increase air supply pressure within the specified range. Jaws slippery on rivet mandrel  3-jaw set worn out.  Metal chips between jaws.  Pusher spring fatigued.  Change 3-jaw set.  Clean the jaws.  Change pusher spring. Rivet mandrel cannot be put into nosepiece  Incorrect nosepiece size chosen.  Jaws get stuck by mandrel not being released.  Use correct size nosepiece for rivet.  Remove any jammed mandrels by disassembling front sleeve and clamping sleeve.
