MAINTENANCE
ENGINE OIL
Change and add oil according to chart below based on air temperature at the time of operation. Do not over-
fill. Use a high-quality detergent oil classified for service SF, SG, SH. SJ or higher. Use no special additives
with recommended oils. Do not mix oil with gasoline.
SAE Viscosity Grades
HYDRAULIC OIL
1. Use SAE 10W-30 API Service SJ or higher motor oil.
2. For proper warranty, change oil every 500 hours or annually, which ever is first.
3. Oil level should be 2-2½" (5-6.4cm) from top of the tank when fluid is cold. Do not overfill.
4. After changing oil, run the machine for a few minutes. Check oil level and for leaks.
5.
Always use extreme caution when filling hydraulic oil tank or checking level to keep system free of con -
taminants. Check and service more frequently when operating in extremely cold, hot or dusty conditions.
6. If the natural color of the fluid has become black or smells burnt, it is possible that an overheating prob -
lem exists.
7. If fluid becomes milky, water contamination may be a problem.
8. If either of the above conditions happen, change oil immediately after fluid is cool and find the cause.
Take fluid level readings when the 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 SJ or higher 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 the tank fill area
as to which type you put in.
TIRE PRESSURE
Caution must be used when inflating a low tire to recommended pressure. Over inflating can cause tires to
explode. All tires should be 20 psi (1.4bar). Improper inflation will reduce tire life considerably.
WHEEL MOUNTING PROCEDURE
1. Set park brake. Turn machine off and remove key.
2. Block wheel on opposite corner.
3. Loosen nuts slightly on wheel to be removed.
4. Jack up machine being careful not to damage underside of machine.
5. Place wheel on hub lining up bolt holes.
6. Torque to 64-74 ft/lb (87-100Nm) using a cross pattern. Re-torque after first 10 hours and every 200
hours thereafter.
7. Lower machine to ground and remove blocks and jack.
