Changing the Oil
Maintenance Service Interval | Maintenance Procedure |
---|---|
Every 100 hours |
|
Crankcase capacity: 2 L (67 oz)—with the filter
-
Start the engine and let it run 5 minutes.
Note: Warm oil drains better.
-
Park the machine so that the drain side is slightly lower than the opposite side to ensure the oil drains completely.
-
Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operator’s position.

When the oil has drained completely, close the drain valve.
Note: Dispose of the used oil at a recycling center.
-
Slowly pour approximately 80% of the specified oil into the filler neck (Figure 32) of the valve cover; refer to Engine Oil Specification.
-
Check the oil level; refer to Checking the Engine-Oil Level.
-
Slowly add the additional oil to bring oil level up to the top-indicator mark on the dipstick.
Changing the Oil Filter
Maintenance Service Interval | Maintenance Procedure |
---|---|
Every 200 hours |
|
Crankcase capacity: 2 L (67 oz)—with the filter
-

Handheld Remote Maintenance
Handheld Remote and the Wireless-Control Module
The handheld remote must link with the wireless-control module before you can use the remote control system. The handheld remote is associated to the wireless-control module at the factory. When you need to re-establish handheld remote and wireless-control module communication (e.g., introducing a new or spare remote control to an existing base unit or changing the signal frequency due to local interference issues), refer to Associating the Remote and the Control Module.
You can associate only Pro Force handheld remote to the Pro Force wireless-control module. Associating a Pro Force remote control to a different Pro Force wireless-control module disassociates that remote control from the original Pro Force machine.
Note: Local interference during operation may disassociate the handheld remote from the wireless-control module. Since the wireless-control module selects the best of numerous signal frequencies during the association process, move the machine to the area of signal disruption or disassociation, and perform the association procedure for best results.
Associating the Remote and the Control Module
Important: Read the entire procedure before starting it.
-
Prepare the machine for maintenance; refer to Preparing for Machine.
-
Rotate the ignition key to the STOP position.
-
While holding the handheld remote, stand near the wireless-control module in an area with an unobstructed, clear line of sight to the antenna (Figure 50).
-
Simultaneously press and hold the ROTATE NOZZLE LEFT and ROTATE NOZZLE RIGHT buttons (Figure 51).
Note: The LED will blink about once per second.
-
Continue to hold both buttons until the LED begins blinking about twice per second.
-
Release both buttons.
-
Press and hold the ROTATE NOZZLE LEFT button (Figure 51).
Note: The LED will blink about twice per second.
-
Continue holding the ROTATE NOZZLE LEFT button (Figure 51) and turn the ignition key start to the RUN position.
Note: The LED turns solid if the procedure is successful. It may take up to 20 seconds for the LED turns solid.
-
Release the ROTATE NOZZLE LEFT button (Figure 51), and rotate the ignition key to the STOP position.
Note: The remote-control system is ready for use with the associated handheld remote.
Replacing the Remote Batteries
Battery specification: AAA (1.5 V)
Quantity: 4
-
Remove the 6 screws securing the cover halves of the handheld remote together, and remove the back cover (Figure 52).
Note: If possible, leave the rubber seal and steel gasket in the channel when removing the cover and batteries.
-
Remove the discharged batteries and properly dispose in accordance with local regulations.
-
Observing battery polarity as shown in Figure 53, insert the new batteries into the terminal cradles.
Note: When installing batteries, observe proper polarity markings (Figure 53) that are embossed onto the battery compartment to avoid damaging the terminal cradles. You will not damage the machine if you incorrectly installing the batteries in the handheld remote, but the handheld remote will not operate.
-
Ensure that the steel gasket and rubber seal are seated in the channel in the cover half and align the back cover to the front cover (Figure 52).
-
Align the lanyard ring over the lanyard pin (Figure 52).
-
Assemble the back cover to the front cover with 6 screws (Figure 52).
-
Torque the screws to 1.5 to 1.7 N⋅m (13 to 15 in-lb).
