10-Hour Check
• Hydraulic Oil Check
Every 10 hours of continual operation,
1. Locate the hydraulic oil cap as shown.
2. Remove the cap and pull out the oil dipstick.
3. Check that the oil mark is within the normal level, which is the section between the marks 1 and 2.
4. Refill with the recommended hydraulic oil if needed.

• Hydraulic Hoses Leakage Check
Every 10 hours of continual operation, check all the hydraulic hoses for leakage.

1. Shut the engine if it is running and allow it time to cool. Support the lift arms with sturdy buttresses. Hoist them if necessary.
Note: ALWAYS support both lift arms BEFORE working under the raised lift arms.
2. Toggle all the control rods to depressurize the hydraulic system.
Note: NEVER service a pressurized hydraulic system
3. Put on necessary protective gears, including goggles and mask.
Note: ALWAYS wear protective gears before the check.

4. Replace damaged hoses or adaptors with identical ones.
Drain the leaked hydraulic oil in an air-tight container and dispose of it following all national and local laws and codes. Seek immediate medical attention if your eyes have contacted the hydraulic oil. Normally, the parts of a hose as shown are more prone to damage.
50-Hour Check
Every 50 Hour of continual use, check:

• Battery Check & Storage
