Gearbox Oil
1. Determine if the gearbox oil is low by removing the oil
plug located on the side of the gearbox. (Figure 16) This
plug will be marked by the "check" decal. The correct
level of the lubrication oil should be to the bottom of
the fill plug.
Figure 16. Gearbox
2. If lubrication oil begins to seep out as the drain plug
is being removed, then it can be assumed that the
gearbox has a sufficient amount of oil.
3. If lubrication oil does not seep out as the drain plug
is being removed, fill with type ISO 680 (P/N 10139)
gearbox lubricant oil until the oil filler hole overflows.
V-Belt Check
A worn or damaged V-belt can adversely affect the
performance of the trowel. If a V-belt is defective or worn
simply replace the V-belt as outlined in the maintenance
section of this manual.
Belt Guard Check
Check for damage, loose or missing hardware.
Blade Check
Check for worn or damaged blades. Check to see if one
blade is worn out while the others look new. If this is
the case there could be a blade pitch problem. Refer to
the maintenance section of this manual for blade pitch
adjustment procedure. Replace any worn blades.

Centrifugal Safety "STOP" Switch
This trowel has been equipped with a centrifugal safety
"

" switch (Figure 17). This switch should be tested
every time the engine is started.
The switching mechanism of this switch should operate
freely and should always be kept in this condition. With the
