MAINTENANCE
HYDRAULIC OIL
1. Use SAE 10W-40 API Service SG motor oil.
2. For proper warranty, change oil every 500 hours or annually, which ever is first and change the filter
after the first 50 hours, then every 250 hours thereafter.
3. The oil level should be 2" to 2

" (5 - 6.4 cm) from top of fill neck when fluid is cold. Do not overfill.
4. After changing oil and/or filter, run the machine for a few minutes. Check oil level and for leaks.
5. Always use caution when filling hydraulic oil tank or checking level to keep system free of contaminants.
Check and service more frequently when operating in extremely cold, hot or dusty conditions.
6. If natural color of fluid is now black or smells burnt, it is possible that an overheating problem exists.
7. If fluid becomes milky, water contamination may be a problem.
8. If either of the above conditions happen, change oil and filter immediately after fluid is cool and find
cause. Take fluid level readings when system is cold.
9. In extreme temperatures you can use straight weight oil. We recommend SAE 30W API Service SG
when hot (above 90°F (33°C)) and SAE 10W API Service SG when cold (below 32°F (0°C)) ambient
temperature. Use either motor oil or hydraulic oil, but do not mix.
10. Oil being added to the system must be the same as what is already in the tank. Mark tank fill area as to
which type you put in.
ENGINE OIL
Change and add oil according to chart below. Do not overfill. Engine oil capacity is 2 quarts. We recommend
high-quality detergent oils classified for service SF, SG, SH, SJ or higher. Do not use special additives. Out -
door temperatures determine the proper oil viscosity for the engine. Use the chart to select the best viscosity
for the outdoor temperature range expected.
SAE Viscosity Grades
Use of multi-viscosity oils (10W-30, etc.) above 80° F (27° C) will result in high oil consumption and possible
engine damage. Check oil level more frequently if using these types of oils.
SAE 30 oil, if used below 40° F (4° C), will result in hard starting and possible engine bore damage due to
inadequate lubrication.
