● Change the gear oil once a year for the rear axle. The oil model is GL-5 90 (used in summer in the south or
north) or GL-5 80W/90 (in severe cold areas or winter in the north, -35℃ or below) gear oil. It is 1.2 liters.
When replacing, first unscrew the oil drain plug, drain the gear oil, clean, and install the oil drain plug, and then
add new gear oil from the filling hole.
Battery Replacement
Remove battery hold downs and cables. Lift batteries out with a commercially available lifting device.
If the batteries have been cleaned and any acid in the battery rack area neutralized as recommended, no corrosion
to the battery racks or surrounding area should be present. Any corrosion found should be immediately removed
with a putty knife and a wire brush. The area should be washed with a solution of sodium bicarbonate (baking
soda) and water and thoroughly dried before priming and painting with a corrosion resistant paint.
The batteries should be placed into the battery racks and the battery hold downs tightened to 45 - 55 in. lbs. (5 - 6
Nm) torque, to prevent movement but not tight enough to cause distortion of the battery cases.
Inspect all wires and terminals. Clean any corrosion from the battery terminals or the wire terminals with a
solution of sodium bicarbonate (baking soda) and brush clean if required.
WARNING To prevent battery explosion that could result in severe personal injury or death, extreme
care must be used with aerosol containers of battery terminal protectant. Insulate the metal container to
prevent the metal can from contacting battery terminals which could result in an explosion.
Use care to connect the battery wires as shown (Ref Fig. 5). Tighten the battery post hardware to 50 70 in. lbs. (6
-8 Nm) torque. Protect the battery terminals and battery wire terminals with a commercially available protective
coating.
