Rotate regutaotor until desired output is achieved. The settings on the regulator are only for reference only and do not denote a specific power output. Turn regulator to position with smaller circle being the least amount of power and larger circle being for the most amount of power. The tool operates in maximum power in reverse. Figure 2 Regulator Valve I,aWARNINe] Once a bolt or fastener is seated, impacting for longer than five (5) seconds will cause excessive wear and possible damage to the impacting mechanism. If it takes longer than five seconds to tighten or loosen your bolt or fastener, we recommend the use of a larger size impact wrench. Lubrication An in-line filter-regulator-lubricator (fig 1) is recommended as it increases toot life and keeps the toot in sustained operation. The in-line lubricator should be regularly checked and filled with air toot oil. Proper adjustment of the in-line lubricator is performed by placing a sheet of paper next to the tools exhaust ports and holding the throttle open approximately 30 seconds. The lubricator is properly set when a light stain of oil collects on the paper. Excessive amounts of oil should be avoided. In the event that it becomes necessary to store the tool for an extended period of time (overnight, weekend, etc.), it should receive a generous amount of lubrication through the air inlet. The toot should be run for approximately 30 seconds to ensure oil has been evenly distributed throughout the toot. The tool should be stored in a clean and dry environment. Recommended lubricants: Use air tool oil or any other high grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting agents and an EP (extreme pressure) additive. Impact clutch lubrication: The oil reservoir in the anvil housing should be checked every 40 hours of operation Remove the oil plug from the housing and hold tool so the the oil port is lower than the anvil housing. Drain oil. Meausure and refill with approximately 1 oz. (30 rot) of SAE 30 weight oil. Never over fill the anvil.
