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.
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.
CONTROLS
Safety Kill Switches
This trowel has been equipped with a safety kill switch or a hand
operated clutch. Safety kill switches should be tested every time
the engine is started.
Centrifugal Type Kill Switch
Located on the main handle tube is a red switch (Figure 18). The
switching mechanism of this switch should operate freely and
should
always
be kept in this condition. With the switch in the OFF
position, the engine should not start or run. The purpose of this
switch is to stop the engine in a runaway situation, (i.e.-the
operator releasing the handle during operation).
NOTE
NEVER!
disable or disconnect the kill switch.
It is provided for operator safety. Injury may
result if it is disable, disconnected or
improperly maintained.
Hand Clutch
Some finisher models are equipped with a
hand operated
clutch
. These units are not equipped with a safety kill switch since
the unit automatically stops rotating when the clutch lever is
released. Clutch operation should be tested each time the machine
is started.
DO NOT let the machine sit unused with the engine at high speed
for an extended period of time. It will cause premature belt wear
or may destroy the belt. Always set the engine speed to idle when
the hand clutch is disengaged.
1. Remove the gasoline cap located on top of fuel tank.
2. Visually inspect to see if fuel level is low. If fuel is low, replenish
with unleaded fuel.
3. When refueling, be sure to use a strainer for filtration. DO
NOT top-off fuel. Wipe up any spilled fuel.
Gearbox Oil
1. Determine if the
gearbox
oil is low by removing the oil
plug located on the side of the gearbox. This plug will be
marked by the "
check
" decal. See Figure 17. The correct
level of the lubrication oil should be to the bottom of the fill
plug.
Figure 17. 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 (Whiteman P/N 10139)
gearbox lubricant oil until the oil filler hole overflows.
