Periodic Maintenance Procedures
Drain the fuel filter/water separator as follows:
1. Position an approved container under the fuel
filter/water separator (Figure 5-7, (1)) to collect
the contaminants.
Figure 5-7
2. Close (Figure 5-7, (2)) the fuel cock
(Figure 5-7, (3)).
3. Loosen the drain cock (Figure 5-7, (4)) at the
bottom of the fuel filter/water separator. Drain
any water collected inside.
4. Hand-tighten the drain cock. (tightening torque:
1.0 - 2.0 N·m (0.1 - 0.2 kgf·m))
If the fuel filter/water separator is positioned
higher than the fuel level in the fuel tank, water
may not drip out when the fuel filter/water
separator drain cock is opened. If this happens,
turn the air vent screw on the top of the fuel
filter/water separator 2 - 3 turns
counterclockwise.
Be sure to tighten the air vent screw after the
water has drained out.
5. Open the fuel cock (Figure 5-7, (3)).
6. Be sure to prime the diesel fuel system when
you are finished. See Priming the Fuel System
on page 4-16.
7. Check for leaks.
■ Check battery
Explosion Hazard!
• Never check the remaining
battery charge by shorting out the
terminals. This will result in a
spark and may cause an
explosion or fire. Use a
hydrometer to check the
remaining battery charge.
• If the electrolyte is frozen, slowly warm the
battery before you recharge it.
• Failure to comply will result in death or
serious injury.
Burn Hazard!
• Batteries contain sulfuric acid.
Never allow battery fluid to come
in contact with clothing, skin or
eyes. Severe burns could result.
Always wear safety goggles and
protective clothing when
servicing the battery. If battery
fluid contacts the eyes and/or
skin, immediately flush the
affected area with a large amount
of clean water and obtain prompt
medical treatment.
• Failure to comply could result in death or
serious injury.
