Frequently Asked Questions - GC8000E Generac

What type of engine oil to use and how to check the level?

Use SAE 10W-30 (from -17 to 38 °C) or SAE 30 (from 10 to 38 °C) oil. To check: place the mower on a level surface, remove the dipstick, wipe it, insert it without screwing, remove and read the level. The level should be within the safe operating range.

How to start a cold engine?

Ensure the machine is on a level surface. Set the depth control lever to START. Press the primer bulb three times (wait 2 seconds between each). Pull the starting lever against the handle, then pull the recoil starter slowly until resistance, then pull quickly. The engine should start in 1-2 pulls.

Why is the blade not turning while the engine is running?

The most common cause is a broken or loose drive belt. Also check for dirt buildup in the deck or insufficient tightening of the blade nut (required torque: 47.5 to 61 Nm). Refer to the belt replacement section of the manual.

How to adjust the cutting depth?

Move the depth control lever forward to increase depth. There are six settings, from ground level to 76 mm (3 in). Do not overload the machine: make multiple passes for deep cuts.

How often should the engine oil be changed?

The first oil change should be done after 5 to 8 hours of use. Then every 50 hours or once per season. Always drain oil when the engine is warm. Use a suitable container and dispose of used oil according to local regulations.

How to replace the blade?

Stop the engine and disconnect the spark plug wire. Use two 19 mm wrenches to hold the nut behind the blade and remove the lock nut. Replace the blade and tighten the lock nut to 47-61 Nm. Never sharpen the blade, replace it if necessary.

What is the recommended spark plug and gap?

Use a TORCH F7RTC or equivalent spark plug. The gap should be 0.7 to 0.8 mm (0.028 to 0.031 in). Tighten the spark plug to 25-30 Nm.

How to clean the air filter?

Remove the air filter cover. Separate the outer foam element from the inner paper element. Wash the foam element with detergent and water, then saturate with clean oil. Tap the paper element to remove dirt or use compressed air from the inside out. Replace if damaged.

What precautions to take for storage over 30 days?

Run the engine until it runs out of fuel, drain the oil, remove the spark plug and pour 29.5 ml of oil into the cylinder, then slowly pull the starter to distribute the oil. Reinstall the spark plug. Clean the machine, inspect it, and store it in a well-ventilated area away from spark sources. Cover it with a permeable material.

Where to find the model and serial numbers?

They are on the nameplate attached to the unit. Write them down in the front cover of the manual. You will need them to order parts or get after-sales service.

Cleaning the Air Filter

WARNING

Explosion and fire. Never clean air filter element with gasoline or low flash-point detergents. Doing so could result in death, serious injury, or equipment damage. (000580)

Proceed as follows to clean or replace air filter:

1. Remove outer wing nut, washer, and air filter cover.
2. Remove inner wing nut and air filter.

IMPORTANT NOTE: Do not allow dirt or debris to enter the carburetor.

1. Separate outer foam element from inner paper element.
2. Inspect inside of paper element for dirt or debris.
3. Inspect both elements for tears or damage.

NOTE: If inner paper element is dirty, or if either element is torn, replace air filter.

1. Wash outer foam element in household detergent and water, or in a nonflammable or high flash-point solvent. Soak foam element in clean engine oil, and squeeze out excess oil.
2. Lightly tap inner paper element against hard surface to remove excess dirt, or blow compressed air through the air filter from the inside out.

NOTE: Do not brush dirt off paper element, this will embed dirt into the fibers.

1. Install cleaned foam element onto inner paper element.
2. Reverse steps 1 and 2 to install clean air filter and air filter cover onto the unit.

Storage

DANGER

Explosion and Fire. Fuel and vapors are extremely flammable and explosive. Store fuel in a well ventilated area. Keep fire and spark away. Failure to do so will result in death or serious injury.

(000143)

! DANGER

Explosion and Fire. Drain fuel in a well ventilated area, into an approved container only after engine has cooled. Failure to do so will result in death or serious injury.

(000180)

WARNING

Risk of Fire. Verify machine has properly cooled before installing cover and storing machine. Hot surfaces could result in fire.

(000109)

NOTE: A yearly checkup or tune-up by an IASD is recommended for optimal performance.

Proceed as follows to put unit in storage for thirty days or more:

1. Run the engine until it is out of fuel.
2. Change engine oil. See Changing Engine Oil.
3. Remove spark plug from cylinder. Pour 1 oz (29.5 mL) oil into cylinder. Slowly pull recoil handle so oil will protect cylinder. Install new spark plug in cylinder. Pull starter handle slowly a few times to distribute oil. Pull recoil slowly until resistance is felt to close cylinder valves. Do not attach spark plug wire.
4. Clean edger. Remove all dirt, leaves, debris, grease, etc. from edger, including cylinder cooling fans, recoil starter cover holes, under fuel tank, and under muffler.
5. Inspect edger for damage. Have damaged parts replaced if necessary.
6. Inspect hardware, and tighten any loose fasteners.
7. Store unit in building with good ventilation, away from spark such as space heaters or pilot lights.
8. Cover edger with a breathable material. Do not use plastic as moisture can collect underneath and cause rusting.
