Vibrator Oil Level Check

CAUTION:

Alwayscleantheareaaroundthevibratoroillevel check hole before removing oil check plug.This will prevent dirt and debris from entering the system.

1.In every 100 hours of operation, with the machine positioned horizontally, remove vibrator oil level check plug (Figure 22) off vibrator 3/4”(19 mm wrench) and see if oil is up to filler port. Be sure to clean area around check hole to prevent dirt and dust from entering.

2.In every 300 hours of operation, replace oil (capacity 1,500 cc). For draining oil through level check hole, have the machine inclined with a sleeper or the like placed under the compaction plate on opposite side.

*Use engine oil 10W-30 for this lubrication.

Replacing Hydraulic Oil

1.Remove the drain plug (Figure 23) at the bottom of the oil tank with a 6 mm hex wrench and drain the hydraulic oil.

2.Clean the filter with light oil.

3.Reinstall the drain plug to the oil tank. Apply seal tape or Roctite #575 to thread portion.

4.Fill tank with hydraulic oil. (Capacity: About 2,500 cc). Use ShellTellus Oil #46 or equivalent.

5.After filling tank, temporarily install cover. Loosen bleeder plug located at the top of the cylinders on side of vibrator (Figure 23). Air remaining in the circuit will be forced out of the bleeder plug.

6.Tighten the breather plug. Check oil level in the tank again.

7.Install the cover of oil tank. Coat packing with liquid packing such as Threebond #1215. Use loctite #242 for mounting screw.

Figure 23. Hydraulic Oil Maintenance

1.Check hydraulic oil in every 100 hours of operation. With handle bar positioned vertically (storage position), remove breather plug (Figure 24) off the top of hydraulic pump and check for proper oil level.

2.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. Over fillingFigure 24. Bleeder Plug (excessive oil) will cause excess oil to blow out

of breather plug.
