PRE-OPERATIONAL CHECKS
CONTROLS AND ACCESSORIES
The following steps should be taken prior to using the power trowel:
1. The operator must be familiar with the location and operation of all controls.
2. The unit ships with oil, but check the crankcase oil and fill the fuel tank before starting. Read and
understand the engine manual supplied with this machine regarding adjustments, operation, and
maintenance before operating this machine.
3. Check the gearbox oil sight glass to ensure the oil is filled halfway up the glass. Use only
MARSHALLTOWN gearbox oil to fill and do not over fill.
4. Check the fuel filter and inspect air filter
5. Check both safety switches and electrical connections.
6. Check nuts and bolts to ensure nothing has loosened during shipping.
Handles
The handle bar is adjusted by simply unscrewing the
adjustment knob attached to the handle and moving
the handle to the preferred height (Figure 12)
Centrifugal Safety Switch
The weight within the safety switch must be able
to move freely without obstruction forward and
backwards. Test the safety switch before every use.
Failure to have a free moving or properly functioning
switch will inhibit the switch from working as intended.
Push the weight away from you so that it is closer to
the engine before starting the trowel.
Throttle
Throttle should be in the furthest forward position
before starting the trowel. Failure to do so will cause
trowel blades to rotate upon starting. Once started pull
throttle towards you to start/increase rotation of blades.
Tether Safety Switch
Secure tether to your person before starting to finish.
If the handle slips out of your hand the plug will detach
from the safety switch and stop the machine. Test the
safety switch before every use. The button on top of
the tether switch can also be used to stop the engine.
