PERIODIC MAINTENANCE
CAUTION
• ALWAYS be environmentally
responsible.
• Follow the guidelines of the EPA or
other governmental agencies for the
proper disposal of hazardous
materials such as engine oil, diesel
fuel and engine coolant. Consult the
local authorities or reclamation facility.
• NEVER dispose of hazardous
materials irresponsibly by dumping
them into a sewer, on the ground, or
into ground water or waterways.
• Failure to follow these procedures may
seriously harm the environment.
Replace the fuel filter at specified intervals to
prevent contaminants from adversely affecting the
diesel fuel flow.

2. Close the fuel cock of the fuel filter / water
separator.
3. Remove the fuel filter with a filter wrench,
turning it to the left (Figure 5-14, (1)). When
removing the fuel filter, carefully hold it to
prevent the fuel from spilling. Wipe up all spilled
fuel.
