SERVICE PROCEDURES
CHECKING BELT TENSION.
The first indication of belt wear is a reduced blade speed despite the engine running at full speed. Inspect
belts often for signs of damage or excessive wear. There is no method for manual adjustment of belt
tension. Excessively worn belts must be replaced.There are some things to look for when checking to see if
adjustment is necessary.
Is the machine wearing out blades unevenly (i.e. one blade is completely worn out while the others
look new)?
Does the machine perceptible rolling motion? Look at the machine while it is running,
Do the guard rings “rock up and down” relative to the ground?
These are some indications that the blade pitch needs to be adjusted.
CHANGING A BLADE
We recommend that all the blades to be changed at the same time. The machine may wobble or bounce if
only some of the blades are changed at one time.
a.
Place the machine on a flat, level surface. Adjust the blade pitch control to make the blades as flat
as possible. Note the blade orientation on the trowel arm.
b.
Remove the bolts and lock washers on the trowel arm, then remove the blade.
c.
Scrape all concrete particles from the trowel arm.
d.
Install the new blade, maintaining the proper orientation for
direction of rotation.
e.
Affix the bolts and lock washers.
f.
Repeat steps 2-6 for all of the remaining blades.
FLOAT DISCS
These round discs attach to the spider and allow the machine to “float” on
“wet” concrete. the disc design allows early floating and easy movement
from wet to dry areas. they are also quite effective in embedding large
aggregates and surface hardeners.
