5.If when charging the battery, violent gassing or spewing of electrolyte occurs, or the battery case feels hot (125°F - 52C), reduce or temporarily halt charging to avoid damaging battery.

6.Always turn charger to “off” before removing a charger lead from the battery.

JUMPER CABLES

The battery on the 8400 is located at the rear of the tractor (see Figure 14).

1.Stop the engine on the vehicle with the good battery.

2.Connect one jumper cable to the positive terminal on the good battery. Connect the other end of the jumper cable to either the positive terminal on the dead battery or the battery side of the solenoid located on the right front of the engine.

3.Connect one jumper cable to negative terminal on dead battery. Connect the other end to ground (frame) of vehicle with the good battery.

BELTS

For efficient performance of your machine, worn or frayed belts must be replaced. Check belt tensions as instructed (see SERVICE AND ADJUSTMENTS on page 16).

ENGINE FUEL FILTER

Before servicing the fuel filter, thoroughly clean outside of filter housing and fuel hoses. Dirt must not be allowed to enter into fuel or fuel system. Refer to manufacturer’s Engine Manual for instructions.

ENGINE

Refer to manufacturer’s Engine Manual for maintenance schedule recommendations. Change oil and oil filter after the first 5 to 8 hours of operation.

ELECTRICAL SYSTEM

Make certain all terminals and connections are kept clean and properly secured.

1.Check switches regularly to be sure they are kept clean and operating correctly.

2.Keep wire harness and all individual wires away from moving parts, hot parts, or sharp edges. This will prevent abrasive wear or potential short circuits.

3.Exercise extreme care when working with electrical system.

HYDRAULIC HOSES

DANGER: To avoid serious bodily injury, always lower mowers to the ground, place all controls in neutral and shut off engine before inspecting hydraulic lines or hoses. Never run hands across tubes, hoses or fittings to check for leaks.

Hydraulic hose and tube lines should be inspected every week to check for cuts, loose connections, kinks, and wear.

Be sure tubes and hoses do not come in contact with other frame parts which could cause abrasive wear. Always replace worn hoses or tubes before operating machine.

1.Assemble nut, sleeves and tube to fitting body with minimum torque (finger tight) until flare contacts seat on fitting body.

2.For tightening reference, mark a line lengthwise on both the nut and adapter fitting with a marker.

3.Using a wrench, rotate the nut to tighten. Turn the nut to the amount shown in the chart below. The line will show which fitting has been tightened and how much.

4.On hoses with “o-ring” fittings, make sure o-rings are clean and hose fittings are properly seated by hand before wrench tightening.

5.Hold the fixed portion of the hose coupling with one wrench; use a second wrench to tighten or loosen the hose nut. This will prevent damage to the fitting seal. When tightening a hose, do not allow it to twist; hold it in a normal, straight position.
