Checking and Adjusting the Control Cable
Checking the Control Cable
| Maintenance Service Interval | Maintenance Procedure |
|---|---|
| After the first hour |
|
| Yearly |
|
Move the control bar back toward the handle to remove the slack in the control cable (Figure 16).
Note: Ensure that a 2 to 3 mm (1/16 to 1/8 inch) gap exists between the control bar and the handle (Figure 16).
Important: The control cable must contain some slack when you disengage the control bar for the rotor blades to stop properly.
Adjusting the Control Cable
-
Slide up the spring cover and unhook the spring from the adjuster link (Figure 17).
Note: You can pull up the adjuster link and cable to make unhooking the spring easier.
-
Move the Z-fitting to a higher or lower hole on the adjuster link as needed to obtain the 2 to 3 mm (1/16 to 1/8 inch) gap between the control bar and the handle (Figure 16).
Note: Moving the Z-fitting higher decreases the gap between the control bar and the handle; moving it lower increases the gap.
-
Hook the spring to the adjuster link and slide the spring cover over the adjuster link.
-
Check the adjustment; refer to Checking the Control Cable.
Note: After extended use, the drive belt may wear and lose its proper belt tension. If the drive belt slips (continuously squeals) under a heavy load, disconnect the spring from the adjustor link and move the upper end of the spring to the hole that is further from the pivot point in the control bar (Figure 18). Then connect the spring to the adjustor link and adjust the control cable.
Note: The belt may slip (squeal) in wet conditions; to dry out the drive system, start the rotor and run it without a load for 30 seconds.
Inspecting the Rotor Blades
| Maintenance Service Interval | Maintenance Procedure |
|---|---|

|
Before each session, inspect the rotor blades for wear. When a rotor-blade edge has worn down to the wear-indicator hole, have an Authorized Service Dealer replace the rotor blades and the scraper (Figure 19).
Changing the Engine Oil
| Maintenance Service Interval | Maintenance Procedure |
|---|---|
| After the first 2 hours |
|
| Yearly |
|
If possible, run the engine for a few minutes before changing the oil to warm it. Warm oil flows better and carries more contaminants.
| Engine oil capacity | 0.70 L (24 fl oz)* |
| Oil viscosity | Refer to Figure 22. |
| API service classification | SJ or higher |
*There is residual oil in the crankcase after you drain the oil. Do not pour the entire capacity of oil into the crankcase. Fill the crankcase with oil as directed in the following steps.
-
Siphon the fuel from the fuel tank into an approved fuel container, or run the engine until it shuts off.
-
Move the machine to a level surface.
-
Place an oil-drain pan under the oil-drain plug, remove the plug, and tip the machine backward and drain the used oil in the pan (Figure 20).
