Activate Battery

c CAUTION: Avoid injury! Prevent Battery Explosions: · Keep sparks, lighted matches, and open flame away from the top of battery. Battery gas can explode. · Never check battery charge by placing a metal object across the posts. Use a volt-meter or hydrometer. · Do not charge a frozen battery; it may explode. Warm battery to 16 degrees C (60 degrees F).

E33536

1. Lift rear hood.

2. Remove nuts (A) and protective cover.

3. Disconnect negative (-) (black) cable from the battery .

4. .Disconnect the positive (+) (red) cable next.

5. Remove battery.

c CAUTION: Avoid injury! BE VERY CAREFUL: Battery acid is a solution of water and sulfuric acid. It is very harmful to skin, eyes, and clothing. Flush eyes with water for 15-30 minutes if acid is splashed into eyes. Seek medical attention immediately if acid is swallowed.

6. Fill the battery:

· Only use battery acid with a 1.265 specific gravity. Slowly add acid (C) to each cell. The solution should be 1/4 in. (6 mm) above plates (D), but NO HIGHER THAN 6 mm (1/4 in.) from the bottom of the filler neck (B).

7. Charge the battery for a MINIMUM of four hours at 4 amps or until specific gravity is 1.250. If your battery charger has a Deep Cycle or Maintenance Free setting, use this setting to charge the battery. Failure to charge the battery before use will reduce battery performance and life.

8. Install the battery:

E33530

9. Connect red positive (+) cable (E) to battery. Apply petroleum jelly or silicone spray to terminal to prevent corrosion. Make sure connection is tight.

E33536

10. Connect black negative (-) cable (F) to battery. Apply petroleum jelly or silicone spray to terminal to prevent corrosion. Make sure connection is tight.

11. Install protective covering over battery. Fasten using nuts (C).

NOTE: DO NOT over tighten screws, it may break plastic cover.

Install Steering Wheel

M77043

1. Remove cap (A).

2. Remove nut from steering bolt and install steering wheel. Fasten using nut and tighten to 33 N·m (24 lb ft.).

3. Install cap (A) in center of steering wheel.

Install Tires

M77001

1. Inflate tires to 34-41 kPa (4-6 psi).

2. Remove nuts from wheel axle bolts.

3. Lift machine high enough to install tires.

NOTE: Valve stem must be to the outside of machine.

M77000

4. Fasten tires using nuts. Tighten to 80 N·m (60 lb ft.).

5. Beveled sides must face inward. Tighten in sequence illustrated, alternately and evenly until recommended torque is reached.

Checking Tire Pressure

c CAUTION: Avoid injury! Explosive separation of a tire and rim parts can cause serious injury or death: · Do not attempt to mount a tire without the proper equipment and experience to perform the job. · Always maintain the correct tire pressure. Do not inflate the tires above the recommended pressure. Never weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure resulting in a tire explosion. Welding can structurally weaken or deform the wheel. · When inflating tires, use a clip-on chuck and extension hose long enough to allow you to stand to one side and NOT in front of or over the tire assembly. · Check tires for low pressure, cuts, bubbles, damaged rims or missing lug bolts and nuts.

M33418

1. Check tires for damage.

2. Check tire pressure with an accurate low pressure gauge.

3. Add air, if necessary:

Connect Lift Actuator

NOTE: The lift actuator, located on the left side of the rear vehicle frame can be positioned two different ways for different functions.

NOTE: Bunker or field rake position (A) and field finisher (B).

NOTE: Machine is shipped in the rake position.
