SAFETY PB-760 LN H/T Personal Condition and Safety Equipment Users of this product risk injury to themselves and others if the unit is used improperly and/or safety precautions are not followed. Proper clothing and safety gear must be worn when operating unit. Physical Condition Your judgment and physical dexterity may not be good: • If you are tired or sick. • If you are taking medication. • If you have taken alcohol or drugs. Operate unit only if you are physically and mentally well.
PB-760 LN H/T SAFETY • DO NOT OPERATE UNIT BAREFOOTED. Keep long hair away from engine and air intake. Retain hair with cap or net. Heavy protective clothing can increase operator fatigue, which may lead to heat stroke. Schedule heavy work for early morning or late afternoon hours when temperatures are cooler. The components of this machine generate an electromagnetic field during operation, which may interfere with some pacemakers.
SAFETY PB-760 LN H/T Repetitive Stress Injuries (RSI) 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 activities may put you at a high risk for developing a Repetitive 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.
PB-760 LN H/T SAFETY Keep a Solid Stance • Maintain footing and balance at all times. Do not stand on slippery, uneven or unstable surfaces. Do not work in odd positions or on ladders. Do not over reach. Avoid Hot Surfaces • Keep exhaust area clear of flammable debris. Avoid contact during and immediately after operation. Equipment Use only ECHO attachments. Serious injury may result from the use of a non-approved attachment combination. ECHO, INC.

PB-760 LN H/T OPERATION OPERATION Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects away from all openings. Always stop engine, disconnect spark plug, and make sure all moving parts have come to a complete stop before removing obstructions, clearing debris, or servicing unit. Blower housing may contain shredder blades and other sharp edges that can cause serious injuries if touched, even if engine is off and blades are not moving.
OPERATION PB-760 LN H/T • DO NOT smoke near fuel. • DO NOT allow flames or sparks near fuel. • Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize. • NEVER refuel a unit when the engine is HOT or RUNNING! • DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground. • DO NOT overfill fuel tank. Wipe up spills immediately. • Securely tighten fuel tank cap and close fuel container after refueling. • Inspect for fuel leakage.
PB-760 LN H/T OPERATION Starting Cold Engine • Recoil starter: Use short pulls - only 1/2 - 2/3 of rope length for starting. Do not allow the rope to snap back in. Always hold the unit firmly. • (PB-760 LN H): Rotate spring loaded throttle arm downward to a comfortable operating position. 1. Throttle Position Lever Move Throttle Position Lever (A) to IDLE position. PB-760 LN H 2. Choke Move choke (C) up to COLD START ( A ) position. 3.

PB-760 LN H/T OPERATION Use reduced speed only when performing light-duty tasks or to comply with local noise regulations. Continuous low speed operation may allow fuel/oil residue to build-up on the piston and cause rapid build-up of carbon on the spark arrestor screen, resulting in overheating and engine damage. To reduce harmful build-up, run engine at wide open throttle for at least 5 minutes every hour, and inspect/clean the spark arrestor screen after approximately 40 hours of operation.
OPERATION PB-760 LN H/T 3. Install back cushion (A) to frame over intake cover. Note: Blower performance may be reduced slightly. B 24 X7531125902 © 11/2015 ECHO Inc.
