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.  
Eye Protection  
Eye protection that meets ANSI Z87.1 or CE requirements must be worn whenever you operate the unit.  
Hand Protection  
Wear no-slip, heavy duty work gloves to improve your grip on the handles. Gloves also reduce the  
transmission of machine vibration to your hands.  
Breathing Protection  
Wear a facemask to protect against dust.  
Hearing Protection  
ECHO recommends wearing hearing protection whenever unit is used.  
Proper Clothing  
Wear snug fitting, durable clothing;  
• Pants should have long legs, shirts with long sleeves.

SAFETY  
PB-770 H/T  
The ignition components of this machine generate an electromagnetic field during operation which  
may interfere with some pacemakers. To reduce the risk of serious or fatal injury, persons with  
pacemakers should consult with their physician and the pacemaker manufacturer before operating  
this machine. In the absence of such information, ECHO does not recommend the use of ECHO  
products by anyone who has a pacemaker.  
Vibration and Cold  
It is believed that a condition called Raynaud’s Phenomenon,  
which affects the fingers of certain individuals, may be brought  
about by exposure to vibration and cold. Exposure to vibration  
and cold may cause tingling and burning sensations, followed  
by loss of color and numbness in the fingers. The following  
precautions are strongly recommended, because the minimum  
exposure, which might trigger the ailment, is unknown.  
• Keep your body warm, especially the head, neck, feet, ankles,  
hands, and wrists.  
• Maintain good blood circulation by performing vigorous arm exercises during frequent work breaks, and  
also by not smoking.  
• Limit the hours of operation. Try to fill each day with jobs where operating the unit or other hand-held  
power equipment is not required.  
• If you experience discomfort, redness, and swelling of the fingers followed by whitening and loss of feeling,  
consult your physician before further exposing yourself to cold and vibration.  
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 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. Some believe that prolonged exposure to  
vibration may contribute to CTS. CTS can cause severe pain for  
months or even years.  
To reduce the risk of RSI/CTS, do the following:  
• Avoid using your wrist in a bent, extended, or twisted position. Instead try to maintain a straight wrist  
position. Also, when grasping, use your whole hand, not just the thumb and index finger.  
Take periodic breaks to minimize repetition and rest your hands.  
• Reduce the speed and force with which you do the repetitive movement.  
• Do exercise to strengthen the hand and arm muscles.  
• Immediately stop using all power equipment and consult a doctor if you feel tingling, numbness, or pain in  
the fingers, hands, wrists, or arms. The sooner RSI/CTS is diagnosed, the more likely permanent nerve  
and muscle damage can be prevented.

EMISSION CONTROL (EXHAUST & EVAPORATIVE)  
PB-770 H/T  
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.  
DO NOT start or operate unit unless all guards and protective covers are properly assembled to  
unit.  
NEVER reach into any opening while the engine is running. Moving parts may not be visible  
through openings.  
Check fuel system for leaks due to fuel tank damage, especially if the unit is dropped. If damage or  
leaks are found, do not use unit, otherwise serious personal injury or property damage may occur.  
Have unit repaired by an authorized servicing dealer before using.  
EMISSION CONTROL (EXHAUST & EVAPORATIVE)  
EPA 2010 and Later and/or C.A.R.B. TIER III  
The emission control system for the engine is EM (engine modification)  
and, if the second to last character of the Engine Family on the Emission  
Control Information label (sample below) is “C”, “K”, or “T”, the emission  
control system is EM and TWC (3-way catalyst). The fuel tank/fuel line  
emission control system is EVAP (evaporative emissions). Evaporative  
emissions for California models are only applicable to fuel tanks.  
An Emission Control Label is located on the engine. (This is an  
EXAMPLE ONLY, information on label varies by engine FAMILY).  
Product Emission Durability (Emission Compliance Period)  
The 50 or 300 hour emission compliance period is the time span  
selected by the manufacturer certifying the engine emissions output  
meets applicable emissions regulations, provided that approved  
maintenance procedures are followed as listed in the Maintenance Section of this manual.

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. Wear gloves to protect hands from sharp  
edges and hot surfaces.  
Operation of this equipment may create sparks that can start fires. This unit is equipped with a spark  
arrestor to prevent discharge of hot particles from the engine. Metal cutters can also create sparks if  
the cutter strikes rocks, metal, or other hard objects. Contact local fire authorities for laws or  
regulations regarding fire prevention requirements.  
Fuel  
Alternative fuels, such as E-15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting ECHO  
requirements are NOT approved for use in ECHO 2-stroke gasoline engines. Use of alternative fuels  
may cause performance problems, loss of power, overheating, fuel vapor lock, and unintended  
machine operation, including, but not limited to, improper clutch engagement. Alternative fuels may  
also cause premature deterioration of fuel lines, gaskets, carburetors and other engine components.  
Fuel Requirements  
Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Gasoline may  
contain up to 10% Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl ether). Gasoline containing  
methanol (wood alcohol) is NOT approved.  
Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD Standards  
must be used. Echo brand premium Power Blend X TM Universal 2-Stroke Oil meets these standards. Engine  
problems due to inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and  
J.A.S.O. FD certified oil, such as Echo premium Power Blend X TM, will void the two-stroke engine warranty.  
Echo premium Power Blend X TM Universal 2-Stroke Oil may be mixed at 50:1 ratio for application in all Echo  
engines sold in the past regardless of ratio specified in those manuals.  
Handling Fuel  
Fuel is VERY flammable. Use extreme care when mixing, storing or handling, or serious personal  
injury may result.  
Use an approved fuel container.  
DO NOT smoke near fuel.  
DO NOT allow flames or sparks near fuel.

OPERATION  
PB-770 H/T  
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. If fuel leakage is found, do not start or operate unit until leakage is  
repaired.  
Move at least 3m (10 ft.) from refueling location before starting the engine.  
Mixing Instructions  
1. Fill an approved fuel container with half of the required  
amount of gasoline.  
2. Add the proper amount of 2-stroke oil to gasoline.  
3. Close container and shake to mix oil with gasoline.  
4. Add remaining gasoline, close fuel container, and remix.  
Spilled fuel is a leading cause of hydrocarbon emissions. Some  
states may require the use of automatic fuel shut-off containers  
to reduce fuel spillage.  
After use  
• DO NOT store a unit with fuel in its tank. Leaks can occur. Return unused fuel to an approved fuel storage  
container.  
Storage - Fuel storage laws vary by locality. Contact your local government for the laws affecting your area.  
As a precaution, store fuel in an approved, airtight container. Store in a well-ventilated, unoccupied building,  
away from sparks and flames.  
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.

PB-770 H/T  
OPERATION  
Operating Blower  
Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a poison gas. Breathing CO can cause  
unconsciousness, serious injury, or death. Exhaust can cause serious burns. ALWAYS position  
unit so that exhaust is directed away from your face and body.  
Always wear safety glasses, hearing protection and a face filter mask or serious personal injury may  
result. Do not point the blower pipe in the direction of people or pets.  
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.  
Read the Safety Section carefully.  
To avoid engine damage due to over-revving, do not block blower pipe.  
1. Use only during appropriate hours.  
2. Allow the engine to warm up at a fast idle for a few minutes.  
3. PB-770H

4. Use lower speed to blow dry leaves from walks, patios and  
drives.  
5. Additional speed may be necessary to clean grass and leaves from a lawn or flower bed.  
6. Higher speed may be necessary to move gravel, dirt, snow, bottles or cans from a driveway, street,  
parking lot or stadium.  
7. Always stop unit using stop engine procedure.  
Note: Never use a higher speed setting than necessary to perform a task. Remember, the higher the engine  
speed, the louder the blower noise. Minimize dust by using blower at lower speeds. Keep debris on  
your property. Be Smart - be a good neighbor.

MAINTENANCE  
PB-770 H/T  
Air Filter  
Level 1.  
REPOWERTM TUNE UP KIT.  
Parts Required:  
1. Close choke (cold start position). This prevents dirt from  
entering the carburetor throat when the air filter is removed.  
Brush accumulated dirt from air cleaner area.  
2. Remove air filter cover, air filter, retainer, and foam pre-filter.  
Brush dirt from inside cover.  
Foam Pre-Filter:  
• Clean foam filter in water/detergent solution and rinse with clean water.  
• Wrap the filter in a clean, dry cloth and squeeze (do not wring) dry. Allow to dry completely before reuse.  
Do not oil.  
Air Filter:  
• Lightly brush debris from filter.  
• Replace filter if it is damaged, very dirty, or the rubber sealing edges are deformed.  
• If filter can be reused, be certain it fits tightly in the airfilter cavity, and is installed with the original side out.  
3. Assemble components in reverse order.  
Fuel Filter  
Level 1.  
REPOWERTM TUNE UP KIT.  
Parts Required:  
Fuel is VERY flammable. Use extreme care when mixing,  
storing or handling, or serious personal injury may result.  
1. Use a clean rag to remove loose dirt from around fuel cap  
and empty fuel tank.  
2. Use the “fuel line hook” to pull the fuel line and filter from the tank.  
3. Remove the filter from the line and install the new filter.  
Note: Federal EPA regulations require all model year 2012 and later gasoline powered engines produced for  
sale in the United States to be equipped with a special low permeation fuel supply hose between the  
carburetor and fuel tank. When servicing model year 2012 and later equipment, only fuel supply  
hoses certified by EPA can be used to replace the original equipment supply hose. Fines up to  
$37,500 may be enforced for using an un-certified replacement part.

MAINTENANCE  
Spark Plug  
Level 2.  
REPOWERTM Tune-Up Kit  
Parts Required:  
Use only NGK BPM-8Y spark plug (BPMR-8Y in Canada)  
otherwise severe engine damage may occur.  
0.65 mm  
(0.026 in.)  
1. Remove spark plug and check for fouling, worn and rounded  
center electrode.  
2. Clean the plug or replace with a new one. DO NOT sand blast to clean. Remaining sand will damage  
engine.  
3. Adjust spark plug gap by bending outer electrode.  
4. Tighten spark plug to 150-170 kgf • cm (130-150 in • lbf).  
Cooling System  
Level 2.  
Parts Required: None if you are careful.  
To maintain proper engine operating temperatures, cooling air must pass freely through the cylinder fin area.  
This flow of air carries combustion heat away from the engine.  
Overheating and engine seizure can occur when:  
• Air intakes are blocked, preventing cooling air from reaching  
the cylinder.  
• Dust and grass build up on the outside of the cylinder. This  
build up insulates the engine and prevents the heat from  
leaving.  
Removal of cooling passage blockages or cleaning of cooling  
fins is considered “Normal Maintenance.Any failure  
attributed to lack of maintenance is not warranted.  
Cleaning Grill  
1. Brush accumulated debris from intake grill between backpack frame and blower housing.

Carburetor Adjustment  
Engine Break-In  
New engines must be operated a minimum duration of two tanks of fuel break-in before carburetor  
adjustments can be made. During the break-in period your engine performance will increase and exhaust  
emissions will stabilize. Idle speed can be adjusted as required.  
High Altitude Operation  
This engine has been factory adjusted to maintain satisfactory starting, emission, and durability  
performance up to 1,100 feet above sea level (ASL) (96.0 kPa). To maintain proper engine operation and  
emission compliance above 1,100 feet ASL the carburetor may need to be adjusted by an authorized ECHO  
service dealer.  
If the engine is adjusted for operation above 1,100 feet ASL, the carburetor must be re-adjusted when  
operating the engine below 1,100 feet ASL, otherwise severe engine damage may result.  
Level 2.  
Parts Required: None  
Note: Every unit is run at the factory and the carburetor is set in compliance with emission regulations.  
Carburetor adjustments, other than idle speed, must be performed by an authorized ECHO dealer.
