Inspect Muffler and Spark Arrester

Inspect the muffler for cracks, corrosion, or other damage. Remove the spark arrester, if equipped, and inspect for damage or carbon blockage. If replacement parts are required, make sure to use only original equipment replacement parts.

Regular Maintenance

WARNING

Replacement parts must be the same and installed in the same position as the original parts or fire could result.

reservoir compartment.

 

2. Look at the hydraulic oil reservoir (A, Figure 13) and observe the oil level. When cold, the oil level should be approximately 1/2” (1,3cm) below the MAX. HOT OIL LEVEL line. The oil level should never be above the MAX. HOT OIL LEVEL line.

3. If necessary, remove the reservoir cap (B, Figure

 

13) and add either Mobil 1, 15W-50 synthetic

 

oil or Castrol Syntec 5W-50 oil. DO NOT use

 

conventional oils. Make sure area around the fill

 

neck of the reservoir is free of dust, dirt, or other
