7. Adjust the turnbuckle until you obtain the proper
gap.
8. Tighten the jam nut.
9. Insert the 2 screws you previously removed on the
belt cover.
10. If the auger/impeller cable is properly adjusted but

Checking the Auger Gearbox
Oil Level
Service Interval: Yearly—Check the auger gearbox oil
and add oil if necessary.
1. Move the snowthrower to a level surface.
2. Clean the area around the pipe plug (Figure 42).
3. Remove the pipe plug from the gearbox.
4. Check the oil level in the gearbox. The oil should be
at the point of overflowing at the filler opening.
5. If the oil level is low, add GL-5 or GL-6, SAE 85-95
EP transmission oil to the gearbox until the point
of overflow.
Note: Do not use synthetic oil.
6. Install the pipe plug in the gearbox.

Changing the Engine Oil

Service Interval: After the first 5 hours—Change the
engine oil.
Every 50 hours—Change the engine
oil. Change the engine oil every 25
operating hours when operating the
engine under a heavy load.
If possible, run the engine just before changing the
oil because warm oil flows better and carries more
contaminants.

Lubricating the Hex Shaft

Service Interval: Yearly
Lightly lubricate the hex shaft yearly with automotive
engine oil (Figure 44).
1. Hex shaft
2. Aluminum friction plate
Important: Do not get oil on the rubber wheel
or the aluminum friction drive plate because the
traction drive will slip (Figure 44).
1. Drain the gasoline from the fuel tank.
2. Tip the snowthrower forward onto its auger housing
and block it so that it cannot fall.
