Keep hands and body clear of the work table when operating the press.
Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip steel toe-capped shoes/boots.
Keep children and unauthorised persons away from the working area.
DO NOT operate the press if any parts are missing as this may cause failure and/or possible personal injury.
