2.1 Laws Pertaining to Spark Arresters
Notice: State Health Safety Codes and Public Resources Codes
specify that in certain locations spark arresters be used on internal
combustion engines that use hydrocarbon fuels. A spark arrester is a
device designed to prevent accidental discharge of sparks or flames
from the engine exhaust. Spark arresters are qualified and rated by
the United States Forest Service for this purpose.
In order to comply with local laws regarding spark arresters, consult
the engine distributor or the local Health and Safety Administrator.

2.2 Operating Safety
Familiarity and proper training are required for the safe operation of
equipment! Equipment operated improperly or by untrained personnel
can be dangerous! Read the operating instructions contained in both
this manual and the engine manual and familiarize yourself with the
location and proper use of all controls. Inexperienced operators should
receive instruction from someone familiar with the equipment before
being allowed to operate the machine.
2.2.1 NEVER operate this machine in applications for which it is not
intended.
2.2.2 NEVER allow anyone to operate this equipment without proper
training. People operating this equipment must be familiar with the
risks and hazards associated with it.
2.2.3 NEVER touch the engine or muffler while the engine is on or
immediately after it has been turned off. These areas get hot and may
cause burns.
2.2.4 NEVER use accessories or attachments that are not recommended by
Wacker. Damage to equipment and injury to the user may result.
2.2.5 NEVER operate the machine with the beltguard missing. Exposed

4. Operation
4.1 Description
The Riding Trowel is a modern, high production machine. Finishing
rate will vary depending on operator skill and job conditions. The
heavy-duty gearboxes are designed to provide exceptional
performance, low maintenance, and trouble-free use in most
conditions. The low speed unit is designed to provide higher torque, to
optimize performance with the use of pans. However, either machine
can be configured to be non-overlapping or overlapping, and can
therefore use either two pans, eight or ten finishing blades.
All WACKER Riding Trowels are equipped with a fail-safe kill circuit
and a low oil shutdown or low oil alert for added job safety and engine
protection. Operating time between fuel refills is approximately 4–4½
hours with rotor speeds between 80 and 120 rpm.
Operation CRT 36-23K / CRT 48-25K
wc_tx000175gb.fm 18
4.2 Features and Controls
Control locations and functions:
The Riding Trowel features a seat with an integrated “operator
presence” system, which works in conjunction with a throttle mounted
switch. This system allows the engine to remain running (idling) with
no operator seated in the seat, as long as the throttle is not depressed.
This system meets all safety requirements and eliminates the need for
a foot-operated “kill switch”.
To familiarize a new operator with the Riding Trowel the following
steps should be taken:
4.2.1 With the operator in the seat, show him or her the functions of the
control arms
(c) and how to start the machine.
a right pitch control m work light (one each side)
b water tank n foot pedal (throttle control)
