inspection/operation Centrifugal Safety "STOP" Switch This trowel has been equipped with a centrifugal safety "STOP" switch (Figure 17). This switch should be tested every time the engine is started. 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).
operation NEVER lift the trowel to unnecessary heights. DO NOT stand underneath the trowel while it is being lifted. Serious damage to the machine or personal injury could be caused by dropping a trowel. 3. Place the centrifugal safety "STOP" switch (Figure 21) in the "ON" position. Starting the Engine OFF 1. Place the engine fuel valve lever (Figure 19) in the "ON" position. ON OFF CENTRIFUGAL SAFETY “STOP” SWITCH Figure 21. Centrifugal Safety"Stop" Switch (ON) ON Figure 19.
operation 5. If starting a warm engine place the choke lever (Figure 23) in the "OPEN " position. 8. Before the trowel is placed into operation, run the engine for several minutes. Check for fuel leaks, and noises that would associate with a loose guard ring and/or covers. Testing the Centrifugal Safety Stop Switch 1. With the engine running at idle, place the safety stop switch lever in the "OFF" position (Figure 26). Verify that the engine shuts off.
operation To Begin Troweling Pitching the Blades (Quick Pitch™ Handle) 1.

maintenance General maintenance practices are crucial to the performance and longevity of your trowel. This equipment requires routine cleaning, blade and trowel arm inspection, lubrication and V-belt inspection for wear and damage. Reference Table 5 and Table 6 for scheduled engine and trowel maintenance.
maintenance NOTICE GAP Operating the engine with loose or damaged air cleaner components could allow unfiltered air into the engine causing premature wear and failure. .028 - .031 IN. (0.7- 0.8 MM.) Engine oil 1. Drain the engine oil when the oil is warm as shown in Figure 43. Figure 44. Spark Plug Gap 2. Remove the oil drain bolt and sealing washer and allow the oil to drain into a suitable container. V-belt 3. Replace engine oil with recommended type oil as listed in Table 4.
maintenance spark arrester cleaning Blade Pitch Adjustment Procedure Clean the spark arrester every 6 months or 100 hours. The maintenance adjustment of blade pitch is an adjustment that is made by a bolt (Figure 48) on the arm of the trowel arm lever. This bolt is the contact point of the trowel arm lever to the lower wear plate on the thrust collar. The goal of the adjustment is to promote consistent blade pitch and finishing quality.
maintenance 2. Pitch the blades as flat as possible. The pitch adjustment bolts (Figure 49) should all barely make contact (0.10 inch max. clearance) with the lower wear plate on the spider. All pitch alignment bolts should be spaced the same distance from the lower wear plate. If one is not making contact, adjustment will be necessary.
maintenance changing blades Trowel arm removal It is recommended that ALL the blades on the trowel are changed at the same time. If only one or some of the blades are changed, the machine will not finish concrete consistently and the machine may wobble or bounce. 1. Each trowel arm is held in place at the spider plate by a hex head bolt (zerk grease fitting) and a roll pin. Remove both the hex head bolt and the roll pin (Figure 53) from the spider plate.
maintenance checking trowel arm straightness trowel arm Lever adjustment Trowel arms (Figure 54) can be damaged by rough handling, such as dropping the trowel on the pad, or by striking exposed plumbing, forms, or rebar while in operation. A bent trowel arm will not allow the trowel to operate in a smooth fluid rotation. If bent trowel arms are suspect, check for flatness as follows: The easiest and most consistent way to adjust the trowel arm lever is to use the Trowel Arm Adjustment Fixture (P.N.
maintenance 7. Once the correct adjustment is made, tighten the lock nut on the trowel arm to lock in place. 8. Loosen locking nuts on the adjustment fixture, and remove trowel arm. 9. Repeat steps for the remaining trowel arms. ReAssembly 1. Clean and examine the upper/lower wear plates and thrust collar. Examine the entire spider assembly. Wire brush any concrete or rust buildup. If any of the spider components are found to be damaged or out of round, replace them. 2.
maintenance LONG-TERM STORAGE For storage of the trowel for over 30 days, the following is required: Drain the fuel tank completely, or add STA-BIL to the fuel. Run the engine until the gasoline in the carburetor is completely consumed. Completely drain the oil from the crankcase and refill with fresh oil. Remove the spark plug. Pour 5 to 10 cc of SAE 30 oil into the cylinder. Turn the engine switch to the START position for a few seconds to distribute the oil. Reinstall the spark plug.
