SAFETY HC-2020 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.
HC-2020 SAFETY • Do exercises 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. All over head electrical conductors and communications wires can have electricity flow with high voltages. This unit is not insulated against electrical current.
SAFETY HC-2020 Never perform blade maintenance procedures while engine is running. Equipment Use only ECHO attachments. Serious injury may result from the use of a non-approved attachment combination. ECHO, INC. will not be responsible for the failure of cutting devices, attachments or accessories which have not been tested and approved by ECHO, INC.

HC-2020 MAINTENANCE * Replacement is recommended based on the finding of damage or wear during inspection. Air Filter Level 1. Parts Required: Tune-Up Kit 1. Close choke (B) (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. Brush dirt from inside cover. 3. Replace filter if it is damaged, fuel soaked, very dirty, or the rubber sealing edges are deformed.
MAINTENANCE HC-2020 Fuel Filter Level 1. Parts Required: Tune-Up Kit 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. Pull the fuel line and filter from the tank. Do not damage fuel line while removing fuel filter from tank. 3. Remove the filter from the line and install the new filter.
HC-2020 MAINTENANCE Spark Plug Level 2. Parts Required: Tune-Up Kit Use only NGK BPM-8Y spark plug (BPMR-8Y in Canada) otherwise severe engine damage may occur. 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).
MAINTENANCE HC-2020 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.
HC-2020 MAINTENANCE Exhaust System Spark Arrestor Screen Level 2. Parts Required: Spark Arrestor Screen, Gasket 1. Remove spark plug lead. 2. Remove muffler cover. 3. Place piston at Top Dead Center (TDC) to prevent carbon/dirt from entering cylinder. 4. Remove exhaust guide (A), gasket (B), and screen (C) from muffler body. 5. Clean carbon deposits from muffler components. Note: When cleaning carbon deposits, be careful not to damage the catalytic element inside muffler. 6. 7.
MAINTENANCE HC-2020 Exhaust Port Cleaning Level 2. Parts Required: As needed: Heat Shield 1. Remove spark plug lead from spark plug, and remove muffler cover. 2. Place piston at top dead center. Remove muffler (A) and heat shield (B). A B Never use a metal tool to scrape carbon from the exhaust port. Do not scratch the cylinder or piston when cleaning the exhaust port. Do not allow carbon particles to enter the cylinder. 3.
HC-2020 MAINTENANCE Carburetor Adjustment The blades must not move at idle, otherwise serious personal injury may result. Periodic carburetor adjustment may be necessary to assure blades do not move at idle. If blades move, readjust carburetor according to these instructions, or see your ECHO Dealer. Engine Break-In New engines must be operated a minimum duration of two tanks of fuel break-in before carburetor adjustments can be made.
MAINTENANCE 1. HC-2020 Check idle speed and reset if necessary. If a tachometer is available, idle speed screw (A) should be set to the specifications found on “Specifications” page of this manual. Turn idle screw (A) clockwise to increase idle speed; counter clockwise to decrease idle speed. A When carburetor adjustment is completed, the cutting attachment should not move at idle, otherwise serious personal injury may result. Lubrication Blades Level 1.
HC-2020 MAINTENANCE 4. Allow cleaning mixture to soften the remaining gummy residue then wipe it from the blade. 5. Apply clean oil to the entire length of the blade. Be certain the blade bolts are lubricated. 6. Wipe excess oil from the blade before putting the unit back in service. Gear Box Level 1. Parts Required: Lithium Based Grease. 1. Clean dirt from the grease fitting (A). 2. Apply 1- 2 pumps of grease into fitting, DO NOT over fill.
MAINTENANCE 1. HC-2020 Move stop switch to STOP position. 2. Disconnect spark plug wire. 3. Remove blade guard. 4. Slide blades to allow file clearance using slots (A) on bottom of blade. Do not pry against cutting edges. 5. File each edge carefully. Follow the original shape of the blade. 6. Install blade guard. A Use new lock nuts each time blade guard is installed. See dealer for correct nuts. 7. Lubricate blades (see “Lubrication”). 8. Connect spark plug wire. Adjustment Level 2.
