General information
JWN Series Ride-On Power Trowel Familiarization
The JWN Series
Take a walk around your trowel. Take notice of all the major components like the engine, blades, air cleaner, fuel system, fuel
Read all the safety instructions carefully. Safety instructions will be found throughout this manual and on the machine. Keep all safety information in good, readable condition. Operators should be well trained on the operation and maintenance of the trowel.
Look at the operator control levers. Grab the control levers and move them around a bit. Notice how moving the control levers causes the gearboxes and frame to move.
Notice the foot pedal which controls the engine speed. Also take a look at the main drive line of the trowel. Take note and reference how the belts look, this is the way the belts should look when adjusted properly.
Before using your trowel, test it on a flat watered down section of finished concrete. This trial test run will increase your confidence in using the trowel and at the same time it will familiarize you with the trowel’s controls and indicators. In addition you will understand how the trowel will handle under actual conditions.
Engine
This trowel is equipped with an air cooled 24 HP Honda gasoline engine. Refer to the engine owner’s manual for specific instructions regarding engine operation. This manual is included with the trowel at the time of shipping. Please contact your nearest Multiquip Dealer for a replacement should the original manual disappear.
Blades
The blades of the trowel finish the concrete as they are swirled around the surface. Blades are classified as combination (10 or 8 inches wide) and finish (6 inches wide). This trowel is equipped with four blades per rotor equally spaced in a radial pattern and attached to a vertical rotating shaft by means of a spider assembly.
Figure 2 and Figure 3 show the location and functions of the controls, indicators and general maintenance parts. Each control may perform more than one function.
Gearboxes
The JWN Series
The gearbox casing has a large oil capacity allowing optimum lubrication to critical points.
Steering Assist
Dual control levers located in front of the operator's seat are provided for steering the trowel. The control levers are linked to two spring loaded cylinders.
Push the left control lever forward and pull the right control lever backward and the trowel will rotate clockwise on approximately a center axis. Pull the left control lever backward and push the right control lever forward and the trowel will rotate counterclockwise. See Table 4 for a complete description on the control levers directional positioning.
Constant Velocity Joints (CV-Joints)
Constant velocity joints insure the efficient transfer of power to the drive shaft and maintain the timing of the gearboxes without any chance of slippage.
Training
For training, please use the “"Training Checklist"” located in the front of this manual. This checklist is not intended to be a substitute for proper training but will provide an outline for an experienced operator to provide training to a new operator.
