Troubleshooting and Maintenance Guide for the Hyundai HYCH7070E-2 Petrol Wood Chipper Electric Start – Genpower

Troubleshooting:

Maintenance & Care

WARNING:

ALWAYS stop the engine and disconnect the spark plug HT lead cap BEFORE doing any repairs or maintenance.
NEVER touch a rotating blade.
Check and maintain the oil and fuel level daily.
Frequently check the wood chipper and make sure that all deposits are removed from the feed hopper and discharge chute.
At regular intervals, check the tightness of all nuts, bolts, and screws.
If the blade hits an obstacle, check for damage and if the machine vibrates badly, STOP the machine and take it to a service dealer.

CAUTION:

ALWAYS refuel and defuel in a well-ventilated area with the engine off and cool. Whilst carrying out any maintenance, you must wear the appropriate Personal Protective Equipment (PPE).

CAUTION:

NEVER use a pressure washer or hose to clean the wood chipper.
Water can penetrate areas of the unit and cause damage to spindles, pulleys, bearings, or the engine.
The use of pressure washers or hosepipes will result in shortened life and reduced serviceability.
Shut down the engine, wait for all moving parts to come to a complete stop, remove the HT lead cap and wait for the engine to cool BEFORE performing any maintenance.

AIR FILTER:

NEVER let the engine run without an air filter being fitted.
A dirty air filter element decreases engine performance, increases fuel consumption, and makes it difficult to start.
You MUST make sure that the housing is free of dust and debris. DO NOT allow any dust or debris to enter the carburettor.
Remove the air filter housing by unscrewing the wingnut in an anticlockwise direction.
Carefully remove the cover.
Unscrew the air filter element wingnut and remove the paper/foam filter element.
Replace the filter element if it shows any signs of wear or damage.
Otherwise, remove the foam filter from the paper filter element and tap the debris for the paper element. Use a low-pressure airline to blow the remaining dust from the paper element by blowing from the inside to the outside.
Wash the foam filter element in a mild detergent solution and allow it to dry. Once dry, soak the foam element in engine oil and remove the excess.
To reinstall, reverse the process above.

SPARK PLUG:

CAUTION: The spark plug MUST be tightened correctly; otherwise, the engine will overheat, causing damage.

To ensure the engine runs correctly, the spark plug gap of 06 – 0.7mm must be maintained and the spark plug must be free of carbon deposits.
To remove the spark plug, remove the HT lead cap and the undo the spark plug in an anticlockwise direction.
Once the plug has been removed, check for visual damage, electrode wear and carbon deposits. Replace a damaged or badly worn spark plug. Clean off any carbon deposits using a soft brass brush.
Check the spark plug gap with a feeler gauge and adjust the electrode to the correct gap of 0.6 – 0.7mm.
Check the spark plug washer for damage and replace if required.
Replace the spark plug by hand to make sure it doesn’t cross thread, tighten the spark plug to a torque of 12/15Nm.

ENGINE OIL:

CAUTION:

Risk of burn injury from HOT engine oil. Allow the oil to cool to WARM before changing the oil. Warm engine oil will drain more easily.
Use SAE30 or 15W40 engine oil. The 420cc engine holds 1100ml of oil. The 212cc engine holds 600ml of oil.
Drain the oil while the engine is warm. Warm oil drains quickly and more effectively.
Remove the oil filler/dipstick and place a suitable container under the drain plug.
Unscrew the drain plug and allow the oil to drain, tilt the machine slightly to ensure all the oil has drained.
Once all the oil has drained, check the drain plug washer and replace if damaged.
Reinstall the drain plug by hand to avoid cross threading and then fully tighten with a spanner.
With the lawn mower/engine on flat, level ground, fill the engine with oil to the upper upper edge of the oil filler neck.
Fill slowly, stopping occasionally to check the oil level. DO NOT OVERFILL.
Screw the oil filler/dipstick in securely.
Wipe up any spilt oil

BATTERY:

The battery is maintenance free and as such requires no special treatment other than keeping it clean.
If the machine has not been used in a while, the battery may need charging.
The battery can be charged by starting the machine manually. Once running, it will charge the battery.
You can also remove the battery and charge it with a mains battery charger.
When disconnecting the battery, you MUST observe the correct polarity. Red wire to the Positive (+) terminal. Black wire to the Negative (-) terminal. DO NOT start the machine without the battery installed.
To access the battery, remove the battery cover retaining bolt and keep in a safe place. Remove the cover and lift the battery out and place it on the floor.
Undo the BLACK wire to the (-) terminal FIRST, the undo the RED wire to the positive (+) terminal and cover it with insulating tape.
Place the battery on charge ensuring you connect the correct charge cable to the correct battery terminal.
Once charge reconnect the battery. Connect the RED positive (+) cable first and then the BLACK negative (-).
