17. Set the snowthrower upright.
18. Install the auger/impeller drive belt around the large
auger/impeller pulley and engine pulley, ensuring that
the belt is on the inside of the idler pulley and the belt
guide (Fig. 25).
19. Adjust the belt guide so that there is 1/8 inch
(3 millimeters) of clearance between the auger/impeller
drive belt and the guide, and secure the belt guide when
the auger/impeller drive belt is tight.
20. Check the auger/impeller drive linkage and adjust it if
necessary. Refer to steps 4 through 7 of Installing the
Auger/Impeller Drive Control Linkage on page 10.
21. Install the belt cover.
22. Connect the wire to the spark plug.
Adjusting the Auger/Impeller
Drive Belt
Operating the snowthrower with an auger/impeller drive
belt that slips decreases the snowthrowing performance and
damages the belt. Check the auger/impeller drive belt for
the proper tension after the first operating hour, after every
five operating hours thereafter. Adjust the belt when
necessary.
Danger
Improperly adjusting the auger/impeller may
cause it to turn when disengaged. A rotating auger
or impeller can cut off or injure fingers, hands, or
feet.
• Keep your face, hands, feet, and any other part
of your body or clothing away from concealed,
moving, or rotating parts.
• Ensure that the impeller brake arm clearance is
maintained.
• Do not adjust the auger/impeller drive belt too
tight because it may cause the auger/impeller to
turn when the control lever is in the Disengaged
position. If this occurs, decrease the belt tension.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the plug (Fig. 16).
3. Check and adjust the belt as instructed in steps 4
through 7 of Installing the Auger/Impeller Drive
Control Linkage on page 10.
4. Connect the wire to the spark plug.
5. Check the belt tension by operating the auger.
6. If the belt still slips, replace it. Refer to Replacing the
Auger/Impeller Drive Belt on page 22.
Important Do not operate the snowthrower if the auger
and the impeller rotate when you disengage the
auger/impeller drive control lever.
Replacing the Auger/Impeller
Drive Belt
If the auger/impeller drive belt becomes worn, oil-soaked,
or otherwise damaged, replace the belt.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the plug (Fig. 16).
3. Remove the two flange-head bolts that hold the belt
cover in place and set the cover aside (Fig. 24).
4. Loosen the belt guide (Fig. 25).
5. Remove the auger/impeller drive belt from the engine
pulley and the large auger/impeller pulley (Fig. 25).
6. Install a new belt around the large auger/impeller pulley
(Fig. 25).
7. Loop the belt over the engine pulley, ensuring that the
belt is on the inside of the idler pulley and the belt guide
(Fig. 25).
8. Adjust the belt guide so that there is 1/8 inch
(3 millimeters) of clearance between the auger/impeller
drive belt and the guide, and secure the belt guide.
9. Check and adjust the auger/impeller drive belt as
instructed in steps 4 through 7 of Installing the
Auger/Impeller Drive Control Linkage on page 10.
10. Install the belt cover.
11. Connect the wire to the spark plug.
Important Do not operate the snowthrower if the auger
and the impeller rotate when you disengage the
auger/impeller drive control lever.
Changing the Engine Oil
Change the engine oil after the first two operating hours,
after every 25 operating hours, and at the end of the
snowthrowing season. If possible, run the engine just
before changing the oil because warm oil flows better and
carries more contaminants.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the spark plug (Fig. 16).
3. Block up the rear of the snowthrower.
