SAFETY IMPORTANT SAFETY INSTRUCTIONS FOR USE OF THE COMPRESSOR WARNING: Death or serious bodily injury could result from improper or unsafe use of compressor. To avoid these risks, follow these basic safety instructions: READ ALL INSTRUCTIONS 1. NEVER TOUCH MOVING PARTS. Never place your hands, fingers or other body parts near the compressor’s moving parts. Never insert your fingers or other objects into the housing's ventilator. Such an action invites the danger of injuries or electric shocks. 2.
16. CHECK DAMAGED PARTS AND AIR LEAK. Before further use of the compressor, a guard or other part is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, air leak, and any other conditions that may affect its operation.
33. THE SAFETY VALVE MUST WORK PROPERLY. Risk of bursting. Before starting the compressor pull the ring on the safety valve to make sure the valve moves freely. If the safety valve does not work properly, over-pressurization may occur, causing air tank rupture or an explosion. REPLACEMENT PARTS When servicing use only identical replacement parts. Repairs should be conducted only by a Hitachi authorized service center.
EXTENSION CORD Use only three-wire extension cords that have three-prong grounding-type plugs and three-pole receptacles that accept the compressor’s plug. Replace or repair damaged cord. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.
OPERATION AND MAINTENANCE NOTE: The information contained in this Instruction Manual is designed to assist you in the safe operation and maintenance of the compressor. Some illustrations in this Instruction Manual may show details or attachments that differ from those on your own compressor.
