Tighten the V Belts
WHILE INSTALLING V-BELT
Check the gearbox oil level before every operation, change the gearbox oil every year.
On side of the gearbox there is a plug. Use “SHELL OMALA 220 (750ml)” gear oil, or equivalent.
Clean the machine after it has been used to prevent the collection of hardened cement. Hard concrete/
cement paste is very difficult to remove. To clean it use an old brush or hand brush.
Be careful while changing the old blades with new. Due to the way the blades wear, the old blades become
very sharp, like a knife blade. As a safety precaution very heavy work gloves during this operation to
prevent the hands being cut. Remove bolts and lock washers on each trowel arm and remove the blades.
Before installing new blades clean all concrete/cement from bottom and side of the trowel, be sure trowel-
ling edge of the blade is behind trowel arm. Install bolts and lock washers on each trowel arm and fasten
securely.
If y
ou
notice a loose on V belt, check the tightness.Especially in first using and V belt change.Check the V
belt tightness after 8 hours later.Using your head finger push the V belt from its middle point.It must strech
about 2cm.If it strechs more, it is loose.
For tightening; loose the motor fixing screws.(tiil motor moves away on the table) Loose the motor lock nut.
Loose the screws, push the motor backward. Checking the V belt tighteness, do the same operations.Until
tighteness of V belt is desired value, screw the motor luck nut, and then screw the motor fixing screws.
RIGHT
WRONG
Install the V belt by closing the center
of pulleys to each other and tighten.
While installing V belt do not use crowbar.
•
Adjust the pulley edges with respect to pulley shafts and V-Belt grooves to be on the same plane.
•
Fix the unbalanced pulleys.
•
V-Belts lengths should be the same in multi-grooved pulleys.
•
Change all V-Belts at the same time in multi-grooved pulleys for preventing worn out.
