4-5-2. Structure and disconnecting/reconnecting of the BTN5, BT6, and BT8 series
・Structure of both ends of chain
A snap attachment is inserted in the link from the underside of the link at each end of the chain to prevent the pin from coming out (snap fit).
・Procedure for disconnecting and reconnecting
- (1)Insert a flathead screwdriver into the gap (about 1 mm) between the link hole and the snap attachment to detach the snap attachment.
- (2)Use a threaded head screwdriver and screw it into the center hole (1 mm dia.) of the pin and pull out the pin to disconnect the chain.
- (3)When connecting the links of a chain, bring both ends of the chain together and insert the pin in the hole from one side. Finally, insert the snap attachment from the underside of the chain. Make certain that the snap attachment does not protrude from the bottom of the link.
Note) Use only the attached or dedicated pins for connecting chain
4-5-3. Disconnecting/connecting of the WT1500/1510/1900/2510/2520 (old type of plug)/2700/3000 series
・Disconnecting
(1)Insert a flathead screwdriver or similar tool with a tip of 2 mm or less in between a chain and a plug on the side of the chain.
(2)Remove the plug by levering it out. Be careful not to let the plug jump at this time.
(3)Use a threaded head screwdriver and screw it into the center hole (1 mm dia.) of the pin and pull out the pin to disconnect the chain.
・Connecting
(1)Connect sections of chain by pulling them towards each other and inserting the pin from one of the ends.
(2)Then use a plug to block the pin insertion section. At this point, confirm the orientation of the plug (check if the shape fits in the pin hole), and push it in until it makes a clicking sound.
(3)Make sure that the plug has been properly installed.
Note) Use only the attached or dedicated pins for connecting chain
4-5-4. Disconnecting/connecting of the WT2515G-M330, BTC8H-M and BTM8H-M
Note) Punch length requires 50 mm or more as an effective length.
・Disconnecting
Place a punch (4.5 mm or less) on the side without a notch and strike a hammer on it to thrust off the pin.
・Connecting
Use dedicated connecting pins (special stepped plastic connecting pin color: orange) only.
Pin should be inserted from the end without notch forward. Pushing pin using punch and hammer to connect the chain.
Pin can be inserted either side of the chain.
・Reconnecting
Do not connect at a location where connecting pins (special stepped plastic connecting pin) have been inserted.
・Special stepped plastic connecting pin
Use only dedicated connecting pins (special stepped plastic connecting pin).
The orange color is designed to distinguish it from pins used for base chain color (white).
Each chain has only one connecting pin (special stepped plastic connecting pin) provided.
