MAINTENANCE WARNING: When servicing use only identical replacement parts. Use of any other parts may create a hazard or cause product damage. WARNING: Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask. WARNING: Disconnect the tool from the air supply before performing maintenance. Failure to do so could result in serious personal injury. GENERAL MAINTENANCE Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc. WARNING: Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury. LUBRICATION Frequent, but not excessive, lubrication is required for best performance. Oil for pneumatic fastening tools added through the air line connection will lubricate the internal parts. Do not use detergent oil or additives as these lubricants will cause accelerated wear to the seals and bumpers in the tool, resulting in poor tool performance and frequent tool maintenance. cold weather operation For cold weather operation, near and below freezing, the moisture in the air line may freeze and prevent tool operation. We recommend the use of air tool lubricant or permanent antifreeze (ethylene glycol) as a cold weather lubricant. CAUTION: Do not store tools in a cold weather environment to prevent frost or ice formation on the tools' operating valves and mechanisms that could cause tool failure and possible injury. NOTE: Some commercial air line drying liquids are harmful to "O" rings and seals. Do not use these low temperature air dryers without checking compatibility. AIR SUPPLY PRESSURE AND VOLUME Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of undersize fittings and hoses, or from the effects of dirt and water in the system. Restricted air flow will prevent the tool from receiving an adequate volume of air, even though the pressure reading is high. The results will be a slow operation or reduced driving power. Before evaluating tool problems for these symptoms, trace the air supply from the tool to the supply source for restrictive connectors, low points containing water and anything else that would prevent full volume flow of air to the tool. 17
