Using the Milwaukee M12 Cable Stapler is easy. First, make sure you have a fully charged M12 battery installed. Then, load the 1' insulated staples into the 45-staple magazine. Align the cable with the moveable cable guides. Squeeze the two-finger trigger to drive the staple. When stapling overhead or in tight spaces, the compact and lightweight design makes it easier to handle. Remember, this stapler only works with Milwaukee 1' insulated staples. Always check the battery fuel gauge to know when it's time to recharge. The dry fire lock-out feature protects the tool, so don't try to force it to fire when there are no staples. For maintenance, keep the tool clean. Wipe it down after use to prevent dust and debris from building up. Store it in the included case when not in use. This will help keep it in good condition and ready for your next job.
