J-SeriesWalk-BehindTrowel Familiarization
This
Take a walk around the trowel. Take notice of all the major components (see Figure 3, pages 16 and 17) like the engine, blades, quick pitch control, air cleaner, centrifugal stop switch etc. Check that there is always oil in the engine.
Read all the safety instructions carefully.Safety instructions will be found throughout this manual and on the trowel. Keep all safety information in good, readable condition. Operators should be well trained on the operation and maintenance of the trowel.
Before using your trowel, test it on a flat watered down section of finished concrete that is free of any debris and other objects.
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. In addition you will understand how the trowel handles under actual conditions.
Engines
This trowel is available with either an 5.0 HP HONDA, 4.6 HP ROBIN, or a 5.0 HP Briggs and Stratton gasoline engine. In addition, a 2.0 horsepower 115/230 VAC, single phase electric motor is also available. Refer to the engine owner’s manual for instructions regarding the operation and maintenance of your engine.The engine manual is included with your trowel at the time of shipping from Whiteman.

Drive System
Power is transferred from the engine or electric motor to the gearbox input shaft via
Gearbox
The gearbox is located beneath the engine and transfers power to the rotor or spider assembly. The gearbox controls the rotational speed of the trowel and is equipped with two shafts (input and output).
Spider
The vertical output shaft of the gearbox connects to a cast hub called the spider.The spider has either 3 or 4 arms that extend outward that are used for attachment of blades or other accessories. Remember as the gearbox output shaft rotates so does the spider assembly.
Blades
The blades of the trowel finish the concrete as they are rotated around the surface. Blades are classified as combination (8 inches wide), float (10 or 8 inches wide), and finish (6 inches wide). This trowel comes equipped with either three or four blades per rotor equally spaced in a radial pattern and attached to vertical rotating shaft by means of a spider assembly.
Centrifugal Stop Switch
