English FEATURES COLLET The collet (C) allows you to securely hold the mandrel of an insert tool. The collet nut (B) and spindle (A) are designed with two flat sides each to allow for easy insert tool assembly with the supplied wrenches. TRIGGER The trigger (D) allows the operator to control the start and stop of the air tool. SAFETY THROTTLE LEVER The safety throttle lever (E) prevents the tool from accidentally being actuated.
INSTALLATION Air Supply Safety Rules For Pneumatic Tools The recommended hook-up is shown in Figure A. Pneumatic tools operate on a wide range of air pressures. For maximum efficiency and longer tool life, the pressure of the air supplied to these tools MUST not exceed the rated PSI at the tool when the tool is running. Using a higher than rated pressure will cause faster wear and drastically shorten the tool’s life. A higher air pressure can also cause an unsafe condition and explosion.
English PREPARATION FOR USE Proper Use Of The Tool Disconnect the air line and pour into the air inlet 1 teaspoon (5cc.) of a suitable pneumatic motor lubricating oil, preferably incorporating a rust inhibitor. Reconnect tool to air supply and run tool slowly for a few seconds to allow air to circulate the oil. Lubricate tool daily if used frequently, or when it starts to slow or lose power. Your new Angle Die Grinder is designed for grinding and deburring operations in confined areas.
Using An Angle Die Grinder Continued pressure rating for air tools and accessories. The regulator output pressure must never exceed the maximum pressure rating. INSERT TOOL ASSEMBLY (FIG. 1, PG. 2) • Loosen the collet (C) on the air die grinder by holding the spindle (A) with the supplied 11mm wrench while loosening the collet nut (B) with the supplied 17mm wrench. • Insert mandrel of an insert tool into the collet (C) and tighten by fastening the collet nut (B) with the 17mm wrench.
OPERATING INSTRUCTIONS English OPERATING PROCEDURES Start-up (Fig. 1, pg. 2) • To begin operation, grip tool and depress safety throttle lever while engaging the trigger. • To mount stones and other accessories, use the wrenches supplied with the tool. Always disconnect air supply before changing any accessories. • The grinder should be gradually applied to the work surface until the stone or burr becomes worn. Always replace excessively worn stones or burrs.
