Slide the dipstick fully into the fill port (Figure 9) without threading it into the port. 6. Remove the dipstick and look at the end.
DANGER In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills. • Never fill the fuel tank inside an enclosed trailer. 1 2 3 • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck.
Using Fuel Stabilizer/Conditioner 1 Use a fuel stabilizer/conditioner in the machine to keep the fuel fresh during storage of 90 days or less. If you are storing the machine for longer, drain the fuel tank; refer to Storage (page 23). Important: Do not use fuel additives containing methanol or ethanol. Add the correct amount of fuel stabilizer/conditioner to the fuel, and follow the directions of the manufacturer. Note: Fuel stabilizer/conditioner is most effective when mixed with fresh fuel.
6. Move the throttle lever to desired setting. Stopping the Engine 1. Turn the engine switch and fuel valve off. 2. Wait for all moving parts to stop before proceeding. Operating the Machine Important: Use the machine on concrete that has not set completely, but ensure that the concrete has set enough to support the weight of the machine. 1. Start the engine. 2. After the engine has warmed up, adjust the throttle to approximately half speed. 3. Adjust the blades to the desired position.
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 25 hours • Change the engine oil. Before each use or daily • • • • • • Check the engine oil level. Check the gearcase oil level. Clean debris from the air cleaner and engine. Lubricate the blade arms. Inspect the air cleaner elements. Check for loose fasteners. Every 40 hours • Check the belt, pulley alignment, belt tension, and belt-guide gap.
Lubrication Engine Maintenance Lubricating the Blade Arms Servicing the Air Cleaner Service Interval: Before each use or daily Service Interval: Before each use or daily—Inspect the air cleaner elements. Grease Type: General-purpose grease. Every 50 hours—Clean the air filter elements. Clean them more frequently in dusty operating conditions. 1. Clean around each grease fitting with a rag and lift the plastic cap off each grease fitting.
4. Remove the cover (Figure 16 Box B). 30 Note: Be careful to prevent dirt and debris from falling into the base. 5W - 30 / 10W - 30 5. Remove the foam and paper elements from the base (Figure 16 Box C). 0 6. Remove the foam element from the paper element (Figure 16 Box D). 20 40 -20 -10 0 7. Inspect the foam and paper elements, and replace them if they are damaged or excessively dirty.
Servicing the Gearcase Oil Service Interval: Every 150 hours Oil Type: 80W-90 gear oil that meets or exceeds API service category GL-5 . Capacity: 1.18 L (1.25 US qt) 1. Set the Dyna-Clutch lever to the Stop position, stop the engine, and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug. 3. Place a pan under the drain plug to catch the oil. 4. Remove the gearcase plug (Figure 18). g021590 1 Figure 20 g021574 Figure 19 1. Gearcase plug 5.
Belt Maintenance Servicing the Spark Plug Service Interval: Every 100 hours—Inspect and adjust the spark plug; replace it if necessary. Checking the Belt, Pulley Alignment, Belt Tension, and Belt-guide Gap Every 200 hours—Replace the spark plug. Use an NGK BPR6ES spark plug or equivalent. 1. Set the Dyna-Clutch lever to the Stop position, stop the engine, and wait for all moving parts to stop. Service Interval: Every 40 hours 1.
Removing and Installing the Belt Guard Replacing the Belt Remove the belt as follows: 1. Stop the machine on a level surface, place the Dyna-Clutch lever in the Stop position, stop the engine, and disconnect the spark plug wire. Remove the belt cover as follows: 1. Remove the 2 hex-washer head bolts (5/16 x 1 inch) that secure the belt guard to the belt-guard bracket (Figure 22). 2. Remove the belt guard; refer to Removing and Installing the Belt Guard (page 18). 3.
Aligning the Pulleys 1. Place a straightedge ruler across the engine pulley and the gearbox pulley (Figure 24). Figure 25 Figure 24 1. Straight edge 3. Engine pulley 2. Gearbox pulley 4. Setscrew 5. Cable 6. Locknuts Note: Lifting the cable housing at the barrel should remove the slack from the cable but apply no tension to the spring. 4. While holding tension on the cable, use your other hand, rotate the jam nuts until the nuts are flush to the clutch bracket (Figure 25). A.
Controls System Maintenance tension on the clutch cable. Shut off the engine and repeat step 7 until the blades do not rotate when the engine is running and the Dyna-Clutch is in the Stop position. Adjusting the Tilt Knob Adjusting the Belt Guide 1. Place the Dyna-Clutch lever in the Run position. 1. Set the Dyna-Clutch lever to the Stop position, stop the engine, and wait for all moving parts to stop. 2. Measure the air gap between the belt and the belt guide (Figure 26). 2.
Adjusting the ProPitch Linkage Rod Ensure that there is still enough tension on the cable and spring to prevent parts from coming unhooked during operation. If the tendency for the blades to rotate when the Dyna-Clutch lever is disengaged cannot be adjusted out of the system without taking all tension off of the cable and spring, carefully inspect the drive belt and Dyna-Clutch lever system for wear or damage. Ensure that all parts are operating freely.
Adjusting the Blades 6. Measure the second blade from the spot previously marked on the floor to the second blades leading edge (Figure 32). Adjust the blades to remove excessive shaking of the machine. 1. Disconnect the spark plug wire and move the Dyna-Clutch lever to the Stop position. 1 2. Place 3 or 4 blocks of equal height under the stationary blade guard (outer ring) to raise the blades off of the floor.
Adjusting the Blade Arms Storage Adjust the blade arms if the machine still shakes excessively after the blades have been adjusted. 1. Set the Dyna-Clutch lever to the Stop position, stop the engine, and disconnect the spark plug wire. 1. Place the machine on a flat surface. 2. Remove dirt and grime from the entire machine. 2. Disconnect the spark plug. Important: You can wash the machine with mild detergent and water. Do not pressure wash the machine.
Troubleshooting Problem Possible Cause Corrective Action The trowel blade turns when the recoil is pulled. 1. The clutch is engaged. 1. Disengage the Clutch. 2. The clutch is not properly adjusted. 3. The belt guide bracket is bent. 2. See Adjusting the Dyna-Clutch Lever. 3. See an Authorized Service Dealer. The trowel blades are wearing unevenly. 1. The blade arm is bent. 1. See Adjusting the Blade Arms. 2. The blade arm need to be adjusted. 3. The tilt mechanism needs to be adjusted. 4.
