HYDRAULIC OIL CHECK
1.Check for any oil leakage from the hoses and joints daily.
2.Check hydraulic oil level every 4 to 5 hours after starting operation.
3.After one week of operation, check hydraulic level twice a day .
4.After two weeks of operation, check hydraulic level once a day .
5.Replace hydraulic oil after first 200 hours and in every 1,000 hours of operation.
CAUTION:
Make sure hydraulic oil is at a normal safe operating level. DO NOT over fill.
REPLACING HYDRAULIC OIL
1.Change the hydraulic oil every 1,000 to 1,500 hours of operation. Change the hydraulic oil more often in high ambient temperature operation.
2.Remove the drain plug and hose tank and drain the hydraulic oil.
3.Reinstall the drain plug to the oil tank.
4.Open the tank cap (Figure 30) and fill tank with hydraulic oil. (Capacity: About 4.5 gallons). Use ShellTellus Oil #46 or equivalent.

5. After filling tank, tighten the tank cap firmly with a wrench.

HYDRAULIC OIL FILTER CHECK
1.The hydraulic oil filter should be replaced after first 25 hours of operation.
2.After first replacement, it should be replaced after 250 hours operation (2 months), every 500 hours of operation (4 months), and every 1,000 hours of operation thereafter.
3.When the suction resistance exceeds 254 mmHg (oil temperature in operation is 140 degrees F), replace filter.
4.To remove the oil filter, wind a cloth around the filter to prevent slipping (Figure 31).
5.Tie a rope securely around the filter (Figure 31).
Figure 31. Cloth and Rope Around Filter
6. Forcibly pull the rope to remove the filter (Figure 32).
Figure 32. Filter Removal
7.Immediately replace with new filter, screwing it on by hand to avoid hydraulic oil leak.
CAUTION:
Make sure that dust , water, and other foreign objects do not enter tank. It is recommended to filter the oil through a cloth.
