PTO clutch.

2. Pull the PTO clutch lever SLOWLY to engage the debris blower.

14

15

NOTE:

For cold weather operation, allow sufficient time for the debris blower components to warm up before beginning to blow debris.

DANGER

!

A safety interlock switch (seat switch) will cause the engine to stop if the PTO clutch is engaged and the operator is not in the seat. The function of this switch should be checked by the operator raising off the seat and engaging the PTO clutch; the engine should stop. If the switch is not working, it should be repaired or replaced before operating the debris blower. DO NOT disconnect the safety switches; they are for the operator’s protection.

IMPORTANT: DO NOT engage the PTO clutch when transporting the machine.

DO NOT engage the PTO clutch with the PTO shaft disconnected (the debris blower removed from the tractor).

Recommendations for Operating the Debris Blower

IMPORTANT:

Operate the engine at full speed when operating the debris blower, to allow the engine to produce full horsepower and to increase efficiency of the engine cooling system.

• When operating on a slope, reduce speed and use caution to start, stop and maneuver. Avoid sharp turns or sudden changes in direction.

• Use optional tire chains or all-terrain tires to improve traction.

• Disengage the PTO clutch to stop the debris blower when transporting the machine and not blowing debris.

• Avoid damage to property and extra cleaning work by carefully choosing the direction

to move the debris.

Orient the blower away from people and property due to the possibility of thrown objects.

!

• To momentarily increase traction in case the drive wheels are slipping, use the lift switch to raise the debris blower slightly and transfer extra weight on the drive wheels.

DANGER

!

DO NOT blow debris with bystanders in the area (especially children or pets).

STOPPING THE MACHINE

1. Slow the engine to idle; put the throttle in the

IDLE

position.

2. Pull the steering levers to the NEUTRAL position and then move the FSC lever backward to the

NEUTRAL-PARK position.

3. Disengage the PTO clutch.

IMPORTANT: DO NOT disengage the PTO clutch with high engine speed (above

1/2 throttle) since the brake action on the PTO drive will cause premature wear of the brake band.

WARNING

!

A brake stops the machine from freewheeling within five (5) seconds after disengaging the PTO clutch. If the brake system malfunctions and the machine does not stop within five (5) seconds, the brake should be adjusted or repaired before operating the machine. Refer to the appropriate Tractor

Operator’s Manual for adjustment procedures.

4. Turn the ignition switch OFF .

WARNING

!

Remove the key from the ignition swith when leaving the machine unattended. This will prevent children and inexperienced operators from starting the engine.

5. Engage the parking brake.

IMPORTANT: The hydrostatic transmissions lock to prevent the machine from rolling freely with the engine stopped. However, if the machine is parked on a slope, it is necessary to engage the parking brake to prevent the machine from creeping. This is due to a small amount of slippage in the hydrostatic transmissions, especially when transmission fluid is warm.
