Checking V-belt
Remove the belt cover and check that
V-belt is properly stretched every 200 hours.
Press on the portion midway between the
two shafts with your fingers strongly. The
belt is properly stretched if that portion bows
by about 10-15 mm.
Checking the clutch
Inspect Clutch concurrently with the inspec-
tion of V-belt. Check visually for burning of
each clutch-shoe. Check for wear the lining
shoe or the like, in the operation check. If
the shoe wears, power transmission is not
performed properly and Clutch slips. Check
wear or any damage to V-groove also. If
V-groove is stained, clean it thoroughly.
Checking Bolt, Engine
The part of Bolt, Engine is made of rubber
material, of which the inferiority like fatigue
or worn leads V-belt tension low. Whenever
checking V-belt, inspect this part for the
reason as well as Shock Absorbing Rubber.

8.4 Checking/Changing V-belt and Clutch
Make this machine level, and remove the oil
level plug off the vibrator. Check that vibra-
tor oil is provided up to the mouth level. The
oil level plug is on the right side of the vibra-
tor case (opposite to the belt side). (Refer to
Fig.1 on page 5.)
Use the engine oil #10W-30 for vibrator oil.
Refer to page 8 for the amount. Drain the
vibrator oil completely by removing the plug
and tilting the body once a month or every
200 hours’ operation. Replace with new oil.
Replace immediately when it was found the
wear, deformation or degradation of elastic
rubber material, which may cause V-belt
come off or the engine to vibration damage
directly and excessively. ( Fig.4 )
8.6 Inspection and Change of Engine Bolt
8.5 Inspection and Change of Vibrator Oil
When the vibration weakens during op-
eration, or this machine does not
vibrate at all though the engine rotates
normally, conduct the inspection or
change of the V-belt and clutch without
regard to the regular inspection of
every 200 hours.
Always stop the engine before inspec-
tion and adjustment. If you are caught
in a rotating part, serious injury might
occur.
