Vibrator Oil Level Check
CAUTION
Always clean the area around the vibrator oil level 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 21) off vibrator (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

Replacing Hydraulic Oil
1.Remove the drain plug (Figure 22) 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 bleeder 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 22. Hydraulic Oil Maintenance
1.Check hydraulic oil in every 100 hours of operation. With handle bar positioned vertically (storage position), remove breather plug (Figure 23) 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 i is at a normal safe operating
level. DO NOT over fill. Over filling (excessive oil)Figure 23. Breather Plug will cause excess oil to blow out of breather plug.
