Toro Snowthrower 38754

Warning: Warm oil flows better and carries more contaminants.

There is residual oil in the crankcase after you drain the oil. Do not pour the entire capacity of oil into the crankcase.

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.

After draining the used oil, return the machine to the operating position.

Install the oil-drain plug and tighten it securely.

Clean around the oil fill/dipstick.

Unscrew the dipstick and remove it.

If the drive belt becomes worn, oil-soaked, excessively cracked, frayed, or otherwise damaged, replace the belt.

1. Remove the drive-belt cover by removing the 3 bolts.

2. Unhook the brake spring from the idler arm to release the belt tension.

3. Remove the screw and curved washer that holds the rotor pulley.

4. Remove the rotor pulley and the drive belt.

5. Install the new drive belt, routing it.

Note: Route the new drive belt first around the engine pulley, then the idler pulley, and finally around the loose rotor pulley positioned just above the rotor shaft.

6. Install the rotor pulley onto the rotor shaft.

7. Install the curved washer and the rotor-pulley bolt and tighten them securely.

WARNING: Replacing the spark plug while the engine is hot can result in burns. Wait until the engine is cool to replace the spark plug.

Check the control cable and adjust it if necessary.

Inspect the rotor blades and have an Authorized Service Dealer replace the rotor blades and scraper if necessary.

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.

Warning: This procedure requires trained personnel with PPE!

Check the control cable and adjust it if necessary.

Move the control bar back toward the handle to remove the slack in the control cable.

Ensure that a 2 to 3 mm (1/16 to 1/8 inch) gap exists between the control bar and the handle.

The control cable must contain some slack when you disengage the control bar for the rotor blades to stop properly.

Slide up the spring cover and unhook the spring from the adjuster link.

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.

Hook the spring to the adjuster link and slide the spring cover over the adjuster link.
