Using this industrial straight hand brake is quite simple. First, place the light - gauge material you want to bend between the clamping arms. Use the right and left cam lever arms to precisely clamp the material. You can adjust the clamping pressure if you're working on something delicate. Once the material is securely clamped, start bending it to your desired angle, up to 120°. Remember, this brake has a maximum capacity of 20 gauge mild steel and 18 gauge aluminum, so don't try to bend materials thicker than that. When it comes to maintenance, keep the brake clean from dust and debris. Check the welded parts and support trusses regularly to ensure they're still in good condition. If you run into any problems, you can always call Baileigh for lifetime technical support, and they'll help you out. Also, be aware that the specifications of this product may change without notice.
