Using the Jet JT9 - 70431 clamp is quite straightforward. First, decide whether you want to use it as a clamp or a spreader. If it's for clamping, adjust the movable jaw to the right position using the Slide - Glide trigger. You can quickly identify the opening capacity with the Precision - Rule™ measurement system. The moveable rail stand/end stop can help you preset the clamping capacity accurately. Then, turn the Acme threaded handle to apply pressure up to 1,000 lbs. If you need to use it as a spreader, simply reverse the clamping movable jaw. When using, make sure the non - marring composite resin jaw faces are in good contact with the workpiece to ensure even pressure. As for maintenance, keep the clamp clean and dry. Wipe off any glue or debris after use. If the handle or trigger seems stiff, you can apply a little lubricant. Avoid dropping the clamp or subjecting it to excessive force that could damage its precision parts.
