Warranty repairs must be performed by an authorized Great Dane servicing dealer.

Avoid Fumes

c CAUTION: Avoid injury! Engine exhaust fumes

contain carbon monoxide and can cause serious illness or death.

Move the machine to an outside area before running the engine.

Do not run an engine in an enclosed area without adequate ventilation.

•Connect a pipe extension to the engine exhaust pipe to direct the exhaust fumes out of the area.

•Allow fresh outside air into the work area to clear the exhaust fumes out.

Engine Oil

Use oil viscosity based on the expected air temperature range during the period between oil changes.

Use oil that meets the following specification:

•See the engine manufacturer’s owner’s manual provided with your machine for the correct specifications.

Checking Engine Oil Level

IMPORTANT: Avoid damage! Failure to check the oil level regularly could lead to serious engine problems if oil level is low:

•Check oil level before operating.

•Check oil level when the engine is cold and not running.

•Keep level between the FULL and ADD marks.

•Shut off engine before adding oil.

NOTE: Check oil twice a day if you run engine over 4 hours in a day.

Make sure engine is cool when checking engine oil level.

1.Park machine safely. (See Parking Safely in the Safety section.)

2.Allow engine to cool.

3.Clean area around dipstick to prevent debris from falling into crankcase.

4.Remove dipstick (A). Wipe with a clean cloth.

5.Install dipstick and allow the cap to rest on the end of the tube. Do not tighten the cap.

IMPORTANT: Avoid damage! To prevent extensive engine wear or damage, always maintain the proper engine oil level. Never operate the engine with the oil level below the ADD mark or over the FULL mark.

6.Remove dipstick and check oil level on dipstick. Oil must be between the ADD and FULL marks.

•If oil is low, add oil to bring oil level no higher than the FULL mark on dipstick.

•If oil level is above the FULL mark, drain to proper level.

7.Install and tighten dipstick.

Changing Engine Oil and Filter

c CAUTION: Avoid injury! Help prevent serious personal injury. Allow the engine, exhaust pipe and muffler to cool before performing this service function.

IMPORTANT: Avoid damage! Change the oil more often if the machine is used in extreme conditions:

•Extremely dusty conditions.

•Frequent slow or low-speed operation.

•Frequent short trips.

1.Run engine to warm oil.

2.Park machine safely. (See Parking Safely in the Safety section).
