vehicles must not touch.

2.Shield eyes.

3.Connect one end of the jumper cable to the battery positive (+) terminal and the other to the auxiliary battery positive (+) terminal. Connect one end of the other cable first to the auxiliary battery (-) negative terminal, and the other end to the Hustler tractor frame. Follow the starting procedures above after the jumper cables are connected as instructed.

4.After engine has started, disconnect the negative jumper cable before disconnecting the positive jumper cable(s).

WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

WARNING: Charge batteries in an open well venti- lated area, away from spark and flames. Unplug charger before connecting or disconnecting from the battery. Wear protective clothing and use insulated tools.

WARNING: Avoid skin and clothing contact with battery acid.

WARNING: Always wear eye protection when checking the battery, acid can cause serious injury to skin and eyes. If contact occurs, flush area with clean water and call physician immediately. Acid will also damage clothing.

Do not drink the battery electrolyte.

Do not allow open flame near the battery when charging.

Hydrogen gas forms inside the battery. This gas is both toxic and flammable and may cause an explo- sion if exposed to flame. Always remove the nega- tive ground first and replace it last.

Do not overfill battery.

Electrolyte may overflow and damage paint, wiring or structure. When cleaning the battery, use soap and water. Be careful not to get soap and water into the battery. Clean the battery terminals with a solu- tion of four parts water and one part baking soda when they become corroded.

WARNING: Shorts caused by battery terminals or metal tools touching metal tractor components can cause sparks. Sparks can cause a battery gas explo- sion which will result in personal injury.

Prevent the battery terminals from touching any metal tractor parts when removing or installing the battery.

Do not allow metal tools to short between the bat- tery terminals and metal tractor parts.

WARNING: Incorrect battery cable routing could cause damage to the tractor and battery cables. This can cause sparks which can cause a battery gas explosion which will result in personal injury.

Always disconnect the negative (black) battery cable(s) before disconnecting the positive (red) cable(s).

WARNING: Always connect the positive (red) bat- tery cable(s) before connecting the negative (black) cable(s).

Engine warm up

In cold weather, run the engine at half throttle for a few minutes to allow engine oil and transmission oil to warm up.

WARNING: Never leave the machine running unat- tended.

Stopping the engine

WARNING: Always apply the park brake when leaving the seat.

Stopping the engine should be done according to the following procedures;

1.Pull the throttle lever fully rearward to the low idle position.

2.Release the HST foot pedals.

3.Engage the parking brake.

4.Place the transmission selector and lift control levers in the “N” position.

5.Turn the key start switch to the “OFF” position.

6.Remove the key.

IMPORTANT: Failure to turn the key start switch to the “OFF" position, after the engine stops, will allow the warning lights to remain on, causing the battery to discharge.

IMPORTANT: Do not stop the engine immediately after hard or extended operation. Keep the engine running at slow idle for about 2 minutes to allow engine to cool down.

Operating the hydrostatic transmission and

PTO

Hydrostatic transmission

The hydrostatic transmission is controlled by the HST foot pedals, cruise control switch, and transmission selector lever. Figure 3-5, Figure 3-8 & Figure 3-9

When operating the transmission selector lever, place the HST foot pedals in the neutral position. If it is difficult to engage, slightly depress the Forward or Reverse foot pedal for smooth engagement.

Never engage or disengage the transmission selector lever when the unit is in motion.

With the transmission selector lever in “H” range (Figure 3- 10), ground speed can be varied from zero to maximum by depressing the forward or reverse travel pedal. In “L” range, speeds are about 60% of “H” range. Maximum speeds in
