Maintenance; Lubricating The Snowthrower; Replacing The Scraper; Replacing The Rotor - Toro 1800 Power Curve Operator's Manual

After clearing the snow, let the motor run for a few
minutes so the ice doesn't freeze any moving parts.
Shut off the motor, wait for all moving parts to stop,
and wipe the ice and snow off the snowthrower. Rotate
the chute crank several times to remove the snow from
the snowthrower.
Lock the snowthrower when you are not using the
snowthrower. Disconnect the extension cord. Hold the
key down, turn it clockwise and remove it from the
handle to prevent an unauthorized person from using
the snowthrower.

Maintenance

Note: Determine the left and right sides of the
snowthrower by standing in the normal operating position.
POTENTIAL HAZARD
If the extension cord is plugged into the
snowthrower and the key is in the handle,
someone could accidentally operate
snowthrower while you are performing
maintenance on it.
WHAT CAN HAPPEN
Operating the snowthrower while performing
maintenance on it can cause serious personal
injury.
HOW TO AVOID THE HAZARD
Disconnect the extension cord before you
perform any maintenance. Hold the key down,
turn it clockwise and remove it from the
handle.

Lubricating the Snowthrower

You do not need to lubricate the snowthrower; all the
bearings were lubricated at the factory for the life of the
snowthrower.

The scraper is located at the bottom of the rotor housing
as shown in Figure 12.
