Personal injury or death could result when towing a disabled machine incorrectly.
Block the machine to prevent movement before releasing the brakes. The machine can roll free if it is not blocked.
Follow the recommendations below, to properly perform the towing procedure.
These towing instructions are for moving a disabled machine a short distance, only a few feet at low speed, no faster than 2 km/h (1.2 mph), to a convenient location for repair. These instructions are for emergencies only. Always haul the machine if long distance moving is required.
Shielding must be provided on the towing machine, to protect the operator if the tow line or bar should break.
Do not allow riders on the machine being towed, unless the operator can control the steering and/or braking.
Before towing, make sure the tow line or bar is in good condition and has enough strength for the towing situation involved. Use a towing line or bar with a strength of at least 1.5 times the gross weight of the towing machine, for a disabled machine stuck in mud or when towing on a grade.
Keep the tow line angle to a minimum. Do not exceed a 30° angle from the straight ahead position.
Quick machine movement could overload the tow line or bar and cause it to break. Gradual and smooth machine movement will work better.
Normally, the towing machine should be as large as the disabled machine. Satisfy yourself that the towing machine has enough brake capacity, weight and power, to control both machines for the grade and distance involved.
To provide sufficient control and braking when moving a disabled machine downhill, a larger towing machine or additional machines connected to the rear could be required. This will prevent it from rolling uncontrolled.
The different situation requirements cannot be given, as minimal towing machine capacity is required on smooth level surfaces to maximum on inclines or poor surface conditions.
Consult your AVSpare dealer for additional towing information for a disabled machine.
Switzerland regulations require a cab parking brake release valve. Consult your AVSpare dealer for further information.
Parking Brake Release System
If the air system should fail and the parking brake can not be released from the cab, the parking brake can be mechanically released. Follow the procedure below.
- 1. Block the machine before manually releasing the brakes.
- 2. Loosen the lock nut (1).
- 3. Turn the releasing bolt (2) in (clockwise) until the brakes are released.
- 4. After towing, turn the releasing bolt (2) back out (counterclockwise) and tighten the lock nut (1).
Do not operate the machine until the parking brake is functioning again.
Hydraulic Drive Train Release
If the driving hydraulics have failed, they can be mechanically released. Follow the procedure below.
- 1. Block the machine before releasing the drive train hydraulics.
Lift up the access cover on the upper structure hydraulic controls.
- 2. Turn the two screws in (clockwise) to the stop on the solenoid valve.
- 3. After towing, turn the two screws back out (counterclockwise).
