Stow SCT36 User Manual

1. Using a piece of 3/4 inch thick steel plate or any surface which

is 

true and flat, check all six sides of each trowel arm for

flatness.

2. Check each of the six sides of the trowel arm (hex section

only) using a ten thousands of an inch (max.) feeler gauge
(Figure 40) between the flat of the trowel arm and an 

ex-

tremely flat  test surface.

3. If the trowel arm is found to be 

uneven or bent, replace the

trowel arm.  A bent trowel will not allow the trowel to operate
in a smooth fluid rotation.

4. Next, check each of the six sides of  the round machined shaft

section of the trowel arm. Each section should have the 

clearance  between the round of the trowel arm shaft and the
test surface.

3. Should the trowel arm inserts (bronze bushing ) come out

with the trowel arm, remove the bushing from the trowel arm
and set  aside in a safe place.  If  the bushing is retained  inside
the spider plate, carefully remove the bushing.

4. Examine the bronze trowel arm bushing insert  (Figure 38),

and clean if necessary.  Replace the bushing if out-of-round
or worn.

1. Remove the trowel blades from the trowel arm by removing

the hex head bolts (Figure 39) from the trowel arm.   The 36"
model will have two hex head bolts per arm and the  46" model
will have three hex head bolts per arm.  Set blades aside.

2.

Wire brush any build-up of concrete from all six sides of the
trowel arm. Repeat this for the remaining  three arms.

Trowel arms can be damaged by
rough handling or by striking
exposed plumbing or forms while in
operation. 

ALWAYS look-out for

objects which might cause damage
to the trowel arms.
