INTRODUCTION ECHO Engine Drill EDR-2100 is a lightweight, high performance, two-stroke engined unit designed for drilling. WARNING DANGER IMPROPER USE OR CARE OF THIS UNIT, OR FAILURE TO WEAR PROPER PROTECTION CAN RESULT IN SERIOUS INJURY. READ AND UNDERSTAND THE RULES FOR SAFE OPERATION AND ALL INSTRUCTIONS IN THIS MANUAL. This Manual provides the information necessary for operation and maintenance.
SAFETY WARNING DANGER WARNING ENGINE DRILL USERS RISK INJURY TO THEMSELVES AND OTHERS IF THE ENGINE DRILL IS USED IMPROPERLY, AND/OR SAFETY PRECAUTIONS ARE NOT FOLLOWED. PROPER CLOTHING AND SAFETY GEAR MUST BE WORN WHEN OPERATING ENGINE DRILL. ALWAYS STOP THE ENGINE WHEN A DRILL JAM OCCURS.

• Wear non-slip, heavy-duty work gloves to improve your grip on the engine drill handles. The gloves also help reduce the transmission of machine vibrations to your hands. PROTECTING OTHERS Spectators, children, fellow workers and animals must be warned to come no nearer than 4.6 m (15 feet) while the engine drill is in use. People working in the area near you should wear the same protective equipment as the operator.
Repetitive Stress Injuries It is believed that overusing the muscles and tendons of the fingers, hands, arms and shoulders may cause soreness, swelling, numbness, weakness and extreme pain in those areas. Certain repetitive hand activites may put you at a high risk for developing a Repetitives Stress Injury (RSI). An extreme RSI condition is Carpal Tunnel Syndrome (CTS), which could occur when your wrist swells and squeezes a vital nerve that runs through the area.
OPERATING TECHNIQUES • When starting to drill, run the engine at full throttle. WARNING DANGER BEFORE DRILLING, BE SURE TO READ AND UNDERSTAND THE ENTIRE OPERATOR’S MANUAL TO AVOID THE CHANCE OF SERIOUS INJURY. • Do not force the drills and only move as quickly as the drills will allow. • Stop the engine and disconnect from ignition cable before: - cleaning or when clearing a blockage; checking, maintenance or working on the machine. • Handle fuel with care; it is highly flammable.

IMPORTANT Use drill bits suited for the material being drilled and for the depth of hole required.
IMPORTANT Stored fuel ages. Do not mix more fuel than you expect to use in thirty (30) days, ninety (90) days when a fuel stabilizer is added. Stored two-stroke fuel may separate. ALWAYS shake fuel container thoroughly before each use. STARTING COLD ENGINE • Stand the engine upright on a level surface. • Place ignition switch in ON (START/RUN) position. • Push purge bulb 3 to 4 times (or until fuel is visible in fuel return line). • Shift choke shutter to close position.
REVERSE ROTATION Clockwise (CW) • This model is equipped with reverse rotation mechanism. • When drilling, set shift lever down to clockwise (CW) rotation position. • If bit is locked due to deep penetration during drilling operation, set shift lever up to counterclockwise (CCW) rotation position and operate reversed for easy pulling-out. • When changing direction of drill rotation, operate as follows: Return engine to idle.
