meter wire must be connected. Follow the procedure

below to connect the maintenance meter wire:

1. See Figure 2-8. Install sensor wire (A) firmly into

sensor wire connector on back of meter.

Figure 2-8. Sensor Wire Connection

2. Find a suitable path for the sensor wire leading to

the engine spark plug. Use two cable ties to secure

the wire to the handlebar or frame.

NOTE: Do not place wire on or near hot surfaces.

3. Wrap meter wire tightly around the spark plug wire,

approximately 1–2 in (2.5–5.1 cm) from the end of

engine oil prior to starting engine. Failure to do so

could result in engine damage.

12 Owner’s Manual for Chipper/Shredder

General Information and Setup

IMPORTANT NOTE: The unit is shipped without oil in

engine. Traces of oil may be in reservoir from factory

testing. Oil must be added prior to initial operation.

Use only the recommended high detergent engine

oil. See Engine Fluid Requirements.

1. Place unit on a firm, level surface. Verify engine is

cooled.

2. See Figure 2-9. Remove oil dipstick/fill cap (A).

Figure 2-9. Oil Dipstick and Fuel Fill

3. Add one-half of the recommended oil. Wait one

minute for oil to settle.

4. Install oil dipstick and screw in.

5. Remove oil dipstick and check oil level. Clean oil

dipstick after checking.

6. Add a few ounces of oil at a time until level reaches

FULL mark. Check oil dipstick frequently to prevent

overfill. Do not overfill.

7. Install oil dipstick and securely finger tighten when

full.

Adding Fuel

NOTE: The unit is shipped without fuel. Fuel must be

added prior to first starting attempt.

1. Place unit on a firm, level surface. Verify engine is

cooled.

2. See Figure 2-10. Remove fuel fill cap (A).

Figure 2-10. Fuel Fill Cap

3. Fill tank with fresh, unleaded fuel (with a minimum

85 octane rating) to 0.25–1.25 in (6.4–31.8 mm)

below top of the fill neck to allow for fuel expansion.

4. Install fuel fill cap. Secure tightly.

Connect Battery Cables

NOTE: The negative terminal battery cable is discon-

nected prior to shipment to prevent discharge.

• See Figure 2-11. Secure negative cable (A) to

negative terminal (B) on battery.

away. Failure to do so will result in death

or serious injury.

(000214)

DANGER

Explosion and Fire. Do not fill fuel tank past full line.

Allow for fuel expansion. Overfilling may cause fuel

to spill onto engine causing fire or explosion, which

will result in death or serious injury.

Owner’s Manual for Chipper/Shredder 13

General Information and Setup

1. See Figure 2-12. Remove valve stem protective

cap (A) and check tire pressure using a tire pres-

sure gauge.

Figure 2-12. Valve Stem Protective Cap

2. Verify tire pressure is in accordance with recom-

mended pressure stamped on side of tire. Add or

remove air as needed.

3. Replace valve stem protective cap.

High Altitude Replacement Kit

The standard carburetor air-fuel mixture is too rich at high

altitudes for this unit. Performance decreases and fuel

consumption increases. A rich mixture also fouls the

spark plug and causes hard starting. Operation for

extended periods of time at an altitude that differs from

what the engine was certified for may increase emis-

sions.

Install an altitude kit, when required, when operating at

higher altitudes. Follow the guide below to determine

when an altitude kit is required:

Kits can be obtained by contacting Generac Customer

Service at 1-888-436-3722 (1-888-GENERAC), or visit-

ing www.generac.com. Kits must be installed by a quali-

fied individual.

NOTE: If a carburetor is replaced, the correct high alti-

tude kit jet will need to be installed into the replacement

carburetor.

The warranty may be void if necessary installation of a

high altitude kit is not made for high altitude use.
