ENGINE MAINTENANCE<br />
Engine Lubrication<br />
Proper engine lubrication depends on ambient temperature<br />
and where the vehicle will be operated. Use the recommended<br />
oil for the weather conditions outside.<br />
NOTE: For engine oil specifications, oil change<br />
intervals, engine filter requirements or general<br />
engine maintenance procedures, refer to the Engine<br />
Operation <strong>Manual</strong> included with your vehicle or the<br />
engine manufacturer’s service manual.<br />
Service Intervals<br />
• Check engine oil daily.<br />
Oil Draining:<br />
• Refer to the engine manufacturer's Engine Operation<br />
and Maintenance <strong>Manual</strong> supplied with your vehicle for<br />
information about draining and refilling engine oil, engine<br />
crankcase capacity, engine oil type, and changing oil filters,<br />
etc.<br />
Engine Maintenance<br />
WARNING! Hot engine oil can be dangerous. You<br />
could be seriously burned. Let the engine oil<br />
cool down before changing it.<br />
• Drain the oil into a container designed for this purpose.<br />
• When draining the oil, remove the plug with the proper<br />
size wrench and keep as far away as possible. Always<br />
keep your forearm parallel to the ground to help prevent<br />
hot oil from running down your arm.<br />
• The oil filler cap must be secured to avoid oil spill causing<br />
a potential fire hazard.<br />
Oil Level Check<br />
• To check the engine oil level, park the vehicle on level<br />
ground and wait 5 minutes <strong>after</strong> shutting the engine OFF.<br />
This allows time for the oil to drain to the oil pan.<br />
• Remove the dipstick and wipe it off with a clean, lint-free<br />
rag.<br />
• Reinsert the dipstick all the way in and pull it out again to<br />
check oil level. Correct oil level is between the low (L)<br />
and high (H) marks on the dipstick.<br />
For further information regarding oil level, see the engine<br />
manufacturer's Engine Operation and Maintenance <strong>Manual</strong><br />
supplied with the vehicle.<br />
