Perform the first engine oil change after 20
hours of operation, then change at every 100
hours.
When the air cleaner element becomes dirty,
the engine does not start smoothly, and suffi-
cient output cannot be obtained. Machine
operation will be affected and the engine life
will be shortened greatly. Do not forget to clean
the element. (For details, please see the sepa-
rate engine operation manual.) If the element
cannot be cleaned, replace it with a new one.
Check of V-belt (Fig. 16)
At every 200 hours, remove the belt cover (top)
to check the tension of the V-belt. The flexibility
of the belt should be about 10 mm when
pushed strongly with your finger at the mid-
point between the axes. When the V-belt is
loose, the engine power is not transmitted well,
resulting in poor compacting force and shorten-
ing the life of the V-belt.
Changing the V-belt
Removing the V-belt
Remove the top and bottom belt covers. Put a
wrench (19mm) on the tightening bolt of the
vibrator pulley (lower side). Put a piece of cloth
at the center of the left side of the V-belt, and
pull the belt strongly towards you. While pulling,
turn the wrench clockwise, then remove the
V-belt.
Installing the V-belt
Set the V-belt on the lower side of the vibrator
pulley. Push the V-belt to the left side of the
upper clutch. Similar to removing the V-belt,
turn the wrench clockwise to install.
Be careful not to get your hand caught
between the belt and clutch pulley. Injury
may occur. Wear gloves when performing
this operation. (Fig. 17)
Checking the Clutch
Check the clutch when checking the V-belt.
Remove the belt cover and check for any seiz-
ing on the clutch outside drum. Also visually
check for wear and damage on V-groove. If the
V-groove is dirty, clean it thoroughly.
Wear on the lining shoe can be checked by an
operation check. Wear on the shoe will result in
poor power transmission, causing slipping.
To stop the operation, perform the starting
steps in reverse. Return the throttle lever
quickly and suddenly to lower the revolution
speed.
