Towing Procedures
Personal injury or death could result when improperly towing a disabled machine.Block the machine to prevent movement before releasing the brakes. The machine can roll free if it is not blocked.Relieve the hydraulic tank and line pressure before any disassembly. Operate the travel levers back and forth with the engine stopped to relieve pressure.Follow the recommendations below, to properly perform the towing procedure.Removing the plugs from the brake cover of the travel motor without first relieving the internal pressure will cause hydraulic oil to spout out.Even after the machine has been turned off, the hydraulic oil can still be hot enough to burn. Allow the hydraulic oil to cool before draining it.High temperature steam from a hot water cleaning device can cause personal injury. Take necessary precautions to prevent the steam from touching your skin.Wear a protective mask, protective clothing and protective shoes before starting hot water cleaning.
To tow the machine, both final drives must be disengaged.Do not operate the travel motors with the final drives disengaged. Damage could result.Clean the travel motor and the nearby areas before releasing the parking brakes.Dirt can damage the travel motor and thereby inflict reduced performance or cause machine malfunctions.For cleaning with a hot water cleaning device, use a spray steam with a pressure not exceeding 2982 kPa (426 psi) to avoid damage to painted areas of the components.
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.Attach cable to towing eye on front if pulling forward, or attach to drawbar pin if pulling to the rear.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
