Many hydraulic problems are a result of low fluid levels.
Before checking any other possibilities, make sure the
hydraulic fluid level is correct. Hydraulic problems could
be a result of the following:
1. Incorrect hydraulic fluid level.
2. Plugged hydraulic oil filter
3. Loose or leaking fittings.
4. Ruptured/damaged hydraulic lines.
5. Faulty hydraulic pump.
Hydraulic Oil System
1. Check hydraulic oil level daily.
2. When checking or adding hydraulic oil, place the
machine so the saw frame is level to get an accurate
reading.
3. Hydraulic oil should be 1/2" to 1" in the Oil Reserve
when cold.
4. If hydraulic oil level is low add oil to 1/2" to 1".
5. Use 15W-40 premium grade engine oil.
6. Change oil and filter annually. See Figure 62.
