5.2. Tensioning of the drive belt

Inspect tensioning of the drive belt on a regular basis. Belt deflection should be about 10mm under finger
pressure (2 kg).
When necessary to tighten the belt, proceed as follows:

Loose two bolt fastening the water tank. Tilt the tank forwards and carefully place aside (not
necessary to disconnect the water hose).

Loose four bolts that fasten the engine to the base plate and a lock nut of the tensioning screw (located
under the water tank).

Tension the drive belt by means of the tensioning screw.

Re-tighten the bolts and the lock nut.

Replace the water tank.
Bear in mind that the drive belt connects the engine and the vibrator, which are in mutual movement
under operation. Be careful not to over tension the belt, so that it is able to allow this movement.
DO NOT OVERTENSION THE BELT!

5.3. Inspection of vibrator oil level

Continually check that oil leaking from the vibrator. Interval control and exchange of oil in the vibrator
