WARNING: Disconnect the spark plug
wire and ground it against the engine
to prevent unintended starting.
WARNING: NEVER attempt to make
any adjustments while the engine is
running, except where specified in the
operator’s manual.
Shave Plate
1. To check the adjustment of the shave plate, place the
unit on a level surface. The wheels, shave plate and
augers should all contact level surface. Note that if the
shave plate is adjusted too high, snow may blow under
the housing. If the shave plate wears out excessively,
or the unit does not self-propel, the shave plate may
be too low and needs to be adjusted.
NOTE: On new units or units with a new shave plate
installed, the augers may be slightly off the ground.
2. To adjust, tip the snow thrower back so that it rests on
the handle. Loosen the four lock nuts and bolts which
secure the shave plate to the housing. See Figure 7.
Move the shave plate to desired position and retighten
the nuts and bolts securely.
Replacing Shave Plate
The shave plate is attached to the bottom of the auger
housing and is subject to wear. It should be checked
periodically. There are two wearing edges and the shave
plate can be reversed. Refer to Figure 7.
1. Remove the four carriage bolts and hex lock nuts
which attach it to the snow thrower housing.
2. Install new shave plate, making sure the heads of the
carriage bolts are on the inside of the housing.
3. Adjust the shave plate according to instructions
above. Tighten the nuts securely before operating the
snow thrower.
NOTE: Call 1-800-800-7310 for information regarding
price and availability of Shave Plate Kit 753-0451 or
contact an authorized MTD Service Dealer in your area.
Control Cable
As a result of both the control cable and the drive belt
stretching due to wear, periodic adjustments may be
necessary.
If the auger seems to hesitate when rotating while the
engine maintains a constant speed, an adjustment is
necessary. Proceed as follows:
The upper hole in the control handle provides for an
adjustment in cable tension. To adjust, disconnect the
end of control cable from the bottom hole in the control
handle and reinsert it in the upper hole. Insert the cable
from the outside as shown in Figure 8. Test the snow
thrower to see if there is a noticeable difference.
Carburetor
WARNING: If any adjustments need to
be made to the engine while the engine
is running (e.g. carburetor), keep
clear of all moving parts. Be careful of
muffler, engine and other surrounding
heated surfaces.
